NAD+: Is It the Fountain of Youth or Just Another Overhyped Supplement?

I was browsing through social media recently when I saw another celebrity talking about getting NAD+ infusions. It made me smile because over the decades of reading and writing about natural health, I've watched one 'miracle' supplement after another make headlines. Some stood the test of time, and I even take them myself. Others quietly disappeared.

So…where does NAD+ fit?

The answer isn't as simple as the advertisements would have you believe.

What Is NAD+?

First of all, nicotinamide adenine dinucleotide, or NAD+, is a substance found in every cell of your body. It helps convert the food you eat into energy and plays an important role in hundreds of chemical reactions.

Scientists also know that NAD+ helps repair DNA, supports healthy mitochondria, and activates proteins called sirtuins that are involved in aging and metabolism.

One consistent finding among researchers is that NAD+ levels decline as we get older.

That naturally raises an interesting question.

If our NAD+ levels go down with age, would increasing them help us stay healthier?

That's what scientists are trying to answer.

Why All the Excitement?

It turns out much of the enthusiasm comes from studies in mice.

When researchers boosted NAD+ levels in laboratory animals, they often found improvements in metabolism, muscle function, endurance, and overall health. Some studies even suggested longer lifespans.

While those are impressive results, animal studies are where research begins, not where it ends.

What About NAD+ IV Therapy?

One of the newest trends involves receiving NAD+ through intravenous infusions.

These treatments can cost several hundred dollars, or even over a thousand dollars per session.

Supporters claim IV therapy works faster and produces better results than oral supplements.

The problem?

There is surprisingly little high-quality research showing that NAD+ IV therapy provides long-term health benefits.

At this point, most of the claims are based on testimonials rather than large, well-controlled clinical trials.

That doesn't mean it doesn't work.

It simply means we don't know yet.

Are There Risks?

Overall, studies suggest that NAD+ precursors like NR and NMN are generally well tolerated when taken for relatively short periods.

Reported side effects have usually been mild and may include nausea, stomach discomfort, headache, fatigue, or diarrhea.

What researchers don't yet know is whether taking high doses for many years is completely safe.

Since these supplements affect cellular metabolism, many scientists believe long-term studies are still needed.

What Have Human Studies Found?

So…here's the encouraging human news.

Several clinical trials have shown that supplements such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) do increase NAD+ levels in humans.

That part seems well established.

The harder question is whether higher NAD+ levels actually make people healthier.

Some studies suggest they might.

Researchers have reported modest improvements in muscle function, insulin sensitivity, and certain markers of metabolic health in some groups of people.

On the other hand, several well-designed clinical trials found little or no improvement in physical performance, blood sugar, memory, or overall health, even though NAD+ levels increased significantly.

In other words, boosting NAD+ may be easier than proving it produces meaningful health benefits.

A recent review of human studies reached much the same conclusion. The supplements consistently raise NAD+ levels, but there isn't enough evidence yet to say they slow aging or prevent disease.

That's an important distinction that sometimes gets lost in the marketing,

Can You Raise NAD+ Naturally?

This is the part I find especially interesting.

Many of the same lifestyle habits we've been hearing about, and that I’ve been writing about for years, also appear to support healthy NAD+ levels.

Regular exercise stimulates mitochondrial function.

Getting enough sleep allows your body to repair itself.

Eating foods rich in vitamin B3 gives your body the raw materials it needs to produce NAD+.

Some research also suggests that intermittent fasting and calorie restriction activate many of the same cellular repair pathways linked to NAD+.

Nobody is making headlines by saying they took a brisk walk, got eight hours of sleep, and ate a healthy dinner.

But these habits have decades of research behind them.

Should You Take It?

At this point, I don't think anyone can honestly say yes or no for NAD+.

The science is exciting, but it's still developing.

If future studies show that NAD+ supplements truly improve healthy aging, I'll be the first to say that's great.

But we're not there yet.

Right now, the best evidence tells us that these supplements raise NAD+ levels. Whether that translates into living longer, thinking more clearly, or feeling younger remains uncertain.

As consumers, it's worth remembering that increasing a number on a lab test isn't always the same as improving health.

I've learned over the years that when something sounds almost too good to be true, it's usually wise to wait for more evidence before spending a lot of money.

Sometimes the newest supplement turns out to be a breakthrough.

Sometimes it turns out to be an expensive lesson.

Only time and good research will tell.

So..to NAD+ now, or NOT is up to you!

Is Blue Light Really an Option to Fight Skin Cancer?

I had never heard of blue light therapy until after I published the Blog last week about Red Light Therapy. A subscriber wrote to me about her husband’s experience with blue light therapy.

I have to admit that my reaction was…huh? 

It turns out blue light is being used a lot. 

It’s being used in Dermatology offices, in skin care commercials, and even in face masks that have a special purpose. It seems to be everywhere these days.

As I discovered, you might have seen a commercial with someone sitting on the couch looking like they're about to board a spaceship while wearing a glowing LED blue light mask.

So...what's the deal with blue light?

I found out that it clears up acne.

It helps heal skin cancer, too.

.So…before you order the latest blue light gadget, there's something important you need to know. The blue light your dermatologist uses is not the same as the one you’ll be using at home, plus there are some other things your dermatologist knows that is necessary for the blue light to even work!

First, Let Me Talk About Acne

Blue light has earned a pretty solid reputation for helping people with acne, and there's good science behind it. It turns out certain wavelengths of blue light can actually kill the bacteria that contribute to acne breakouts. It also helps calm inflammation and may reduce some of the oil production that feeds those annoying pimples.

This means:

No needles.

No medications.

Just light.

Sounds pretty good, and that's why many dermatologists recommend blue light therapy as part of an acne treatment plan, especially for people who want to avoid stronger medications.

How About Going To The Next Level  

It turns out dermatologists are also using blue light to destroy precancerous cells.

It’s true, but there’s a catch. 

The blue light doesn't do the work by itself. 

Before the blue light is even turned on, the dermatologist needs to apply a prescription medication called aminolevulinic acid to the damaged skin.

It turns out that abnormal cells soak it up like a sponge. Healthy cells? Not as much.

Patients then need to wait for a couple of hours while those damaged cells absorb the medication, and only then does the blue light come into play.

When the light shines on those medication-filled cells, it triggers a chemical reaction that creates a special form of oxygen. That oxygen destroys the abnormal cells while leaving most of the healthy skin around them alone.

This is a great example of targeting with incredible precision instead of using a "one-size-fits-all" approach.

What Can It Actually Treat?

This treatment, called Photodynamic Therapy (PDT), is used most often for actinic keratoses. These are rough little patches that many of us dismiss as "just dry skin". They are actually areas of sun damage that can eventually turn into squamous cell skin cancer if left untreated.

Blue light PDT can often stop that progression before it starts.

It's also used for some very early basal cell skin cancers, and for a condition called squamous cell carcinoma in situ, where abnormal cells are still confined to the surface of the skin.

This means instead of cutting away large areas, doctors can often treat an entire field of sun-damaged skin at the same time. 

But Before We Crown Blue Light the Superhero...

Blue light has a weakness…it simply can't travel very deep into the skin.

That means it won't treat aggressive skin cancers or melanoma.

Those require completely different treatments because they extend much deeper than the light can reach.

So, if you discover a changing mole or suspicious spot, please don't assume your home LED mask is the answer. You’ll need your dermatologist to check it out.

And About That Recovery...

Someone being treated with blue light also needs to know that after their photodynamic therapy, their skin becomes incredibly sensitive to light.

And it’s not just sunshine that you have to avoid!

Even bright indoor lights can trigger the medication that's still in your skin. This means for about 48 hours after treatment, patients become “professional shade seekers”.

The treated area usually looks and feels like a pretty serious sunburn. Redness, peeling, swelling, and some stinging are all parts of the healing process.

Fortunately, it usually settles down within several days.

So...Should You Buy That Blue Light Mask?

If your goal is to treat mild acne, it may be worth considering. Many people see improvement with regular use.

If your goal is to treat precancerous skin damage or skin cancer...FORGETABOUTIT!

Save your money because those treatments require prescription medication, medical-grade equipment, and the expertise of a dermatologist.

It turns out, in that case, the most important part of the treatment isn't the light.

It's everything that happens before the light is turned on.

On The Bright Side

Until the subscriber told me about blue light therapy, I would not have guessed that a blue light could help destroy harmful cells, calm inflamed skin, and prevent some skin cancers from progressing!

I started last week’s blog with the old kids’ game of Red Light…Green Light 1,2,3.

So…I guess an update to that game would now be Red Light…Green Light…Blue Light…and whatever light is coming next -1,2,3!

Red Light Therapy Miracle Treatment or Wellness Hype? What the Research Really Says

I remember as a kid playing a game called Red Light, Green Light 1,2,3.

So…today, it’s only the red light that’s my focus.

As a matter of fact, today it seems like everywhere I look, someone is talking about red light therapy. There are ads for masks that promise younger-looking skin, beds that claim to improve your health, and handheld devices that are supposed to reduce pain, help wounds heal, and even boost your energy.

Let’s explore this further, because whenever I see something promoted as the answer to almost everything, I want to make sure it’s real.

So, I decided to look at what the research actually says.

The first thing I discovered is that there are really two types of light often discussed together.

Red light has wavelengths of about 620 to 700 nanometers, and primarily affects the skin and tissues close to the surface.

Near-infrared light ranges from about 700 to 1,100 nanometers and penetrates deeper into muscles, joints, and other tissues.

Scientists often refer to both as photobiomodulation, which simply means using specific wavelengths of light to stimulate changes inside cells.

The theory is interesting. These wavelengths appear to stimulate mitochondria, the tiny power plants inside our cells, to produce more ATP. This is the molecule our bodies use for energy. Researchers also believe these wavelengths may reduce oxidative stress and inflammation.

That sounds impressive.

But does it actually work?

The answer is...sometimes.

Where the Research Looks Promising

One of the strongest areas of research is wound healing.

Several studies have found that red light therapy can speed the healing of wounds and reduce inflammation after injuries. A 2014 review published in Photomedicine and Laser Surgery concluded that photobiomodulation has beneficial effects on tissue repair and wound healing.

There is also fairly good evidence for reducing certain types of pain.

Research has shown benefits for conditions such as osteoarthritis, chronic neck pain, and tendon injuries. A large review published in The Lancet found that low-level laser therapy reduced chronic neck pain better than a placebo in many patients.

Dermatologists have also been using red light for years, and studies suggest it can improve collagen production, reduce wrinkles, and help certain acne patients by decreasing inflammation and promoting skin repair.

Athletes have become interested as well.

Some research suggests using red or near-infrared light before exercise may reduce muscle fatigue and improve recovery afterward. A systematic review published in the Journal of Biophotonics found encouraging results, although the authors noted that treatment timing and dosage are critical.

Now for the Downsides

Here's where you need to be careful.

Many of the claims being made online go far beyond what the research currently supports.

Can it cure Alzheimer's disease?

Reverse diabetes?

Treating depression?

Boost immunity?

Increase longevity?

Well…to put it simply, the evidence isn't there…yet.

Researchers are actively studying these possibilities, and some early results are intriguing. But intriguing isn't the same as proven.

Another issue is that not all devices are created equal.

Many inexpensive products sold online don't provide enough power or the correct wavelengths to produce the effects seen in research studies.

In other words, just because something glows red doesn't mean it's therapeutic.

Dosage also matters since too little light may do nothing, and too much may actually reduce the desired effects.

Scientists even have a name for this: the biphasic dose-response effect. More is not always better.

Then there's the cost.

Some home devices cost several hundred dollars. Others are well over a thousand.

That's a significant investment for something that may or may not help your particular condition.

So…The Next Question: Is It Safe?

Fortunately, red and near-infrared light therapy appears to be quite safe when quality devices are used correctly. If there are side effects, the reports are that they are mild and temporary. Some of the side effects are eye strain, headaches, or skin irritation. All of these are usually from improper use or excessive exposure. So…follow the damn instructions!

Unlike ultraviolet (UV) light, these wavelengths do not appear to damage DNA or increase skin cancer risk.

However, eye protection is recommended with many higher-powered devices, especially lasers, and people taking medications that increase light sensitivity should talk with their healthcare provider before using them.

My Take

I'm encouraged by the research because this isn't one of those therapies with no science behind it.

There are legitimate studies showing benefits for wound healing, pain relief, and certain skin conditions.

At the same time, I think the marketing has gotten ahead of the evidence. (When has that ever happened in drug advertising??!!)

Whenever someone claims that one treatment helps almost every disease known to medicine,  my "healthy skepticism meter" starts flashing.

As with so many natural health approaches, red light therapy isn't magic.

It isn't a cure-all.

But for some people, and for some conditions, it may become another useful tool in the toolbox.

And that's probably the healthiest way to look at it.

One Final Thought

Red light therapy is interesting, and I expect we'll learn much more about it over the next few years. But I also think it's important to keep things in perspective.

Regular exercise, eating a healthy diet, getting enough sleep, managing stress, and spending some time outdoors have far more evidence supporting their benefits than any light therapy device currently on the market.

If red light therapy helps, think of it as one more tool in your wellness toolbox, not a replacement for the healthy habits that can or are serving you well.

Your Heart Has a Brain of Its Own: What Science Is Discovering About the Heart-Brain Connection

 

Have you ever had a "gut feeling" about something? Or perhaps you've made a decision that just felt right in your heart, even when logic coming from your brain told you otherwise?

For centuries, people have spoken about listening to their hearts. Modern science is now revealing that there may be much more to this idea than was once believed.

Most of us were taught that the brain is the command center of the body and the heart is simply a pump that keeps blood moving. While the heart certainly performs that critical function, researchers have discovered something remarkable: the heart has its own nervous system, which some researchers started referring to as the "little brain."

This doesn't mean your heart is sitting there solving math problems or writing novels. However, it does mean that your heart is constantly gathering information, processing signals, and communicating with the brain and the rest of the body in ways scientists are only beginning to understand.

This research is really pointing out how interconnected our bodies truly are.

The Heart's Little Brain

This new information comes from researchers in the field of neurocardiology. They have identified what they call an intrinsic cardiac nervous system within the heart. This system contains thousands of specialized nerve cells and functions independently in many ways.

Neurocardiologist Dr. J. Andrew Armour, one of the pioneers in this field, first described this network as a "little brain" in the heart because it can process information, learn, remember patterns, and influence how the heart functions (pretty cool, and there is more to come).

The researchers have even found that communication between the heart and brain is actually a two-way street!

For years, scientists assumed the brain was always in charge, and the heart simply followed instructions. Today, research shows that the heart is constantly sending information back to the brain.

In fact, many of the signals traveling through the nervous system are actually moving from the heart to the brain rather than the other way around.

Think about that for a moment.

Your heart is continuously communicating with your brain, influencing emotions, stress responses, attention, and even how clearly you think.

The Heart Talks to the Body in Four Different Ways

According to research from the HeartMath Institute, the heart communicates with the brain and body through four primary pathways.

1. Through the Nervous System

The heart sends signals through nerves that connect directly to the brain.

These signals influence areas involved in emotional regulation, decision-making, memory, and stress management.

2. Through Hormones and Biochemicals

Most people don't realize that the heart is also a hormone-producing organ.

It releases hormones and signaling molecules that help regulate blood pressure, fluid balance, and other important bodily functions.

3. Through Physical Rhythms

Every heartbeat creates pressure waves that travel throughout the circulatory system.

These rhythmic patterns carry information that affects organs and tissues throughout the body.

4. Through Electromagnetic Fields

The heart generates the strongest measurable electromagnetic field in the body.

Researchers have even measured that this field extends beyond the physical boundaries of the body. It may be that when two people meet, and they are attracted to each other, it’s their hearts that are communicating with each other!

Why Your Emotional State Matters

One of the most interesting discoveries involves something called heart rate variability, or HRV.

Most people assume that a healthy heart beats with perfect regularity like a metronome.

Surprisingly, that's not the case.

A healthy heart naturally varies the time between beats. This variation reflects the flexibility and adaptability of the nervous system.

Higher HRV is generally associated with better resilience, improved stress management, and greater overall health.

What researchers have also discovered is that our emotions affect these heart rhythms.

When we experience frustration, anger, anxiety, or chronic stress, our heart rhythms tend to become more erratic.

On the other hand, feelings such as gratitude, appreciation, compassion, and love tend to create smoother and more coherent heart rhythm patterns.

This may help explain why positive emotional states often leave us feeling more balanced, clear-headed, and energized.

Can Positive Emotions Improve Health?

This is where the research becomes even more interesting.

The HeartMath Institute has spent years studying what they call "heart coherence"—a state in which the heart, brain, and nervous system are working together in a more synchronized manner.

When people intentionally focus on positive emotions such as gratitude or appreciation, their heart rhythm patterns often become more coherent.

With coherence, many people report feeling calmer, thinking more clearly, and handling stress more effectively.

Now, this doesn't mean we should ignore difficult emotions, or pretend life is always wonderful.

Life happens…Challenges happen…Stress happens.

But learning how to intentionally shift your emotional state may be one of the most powerful tools you have for improving both mental and physical well-being.

So…How Can You Strengthen Your Heart-Brain Connection?

The good news is that there are simple ways to support healthy heart-brain communication.

Practice Gratitude Daily

This may sound overly simple, but gratitude has been shown to positively influence heart rhythms.

There is even a meditation technique called Loving Kindness Meditation where you focus on sending feelings of love, compassion, goodwill to yourself and others. Researchers actually found that the meditators' social interactions increased, and even their muscle strength increased!

So, at least take a few moments each day to focus on something you genuinely appreciate.

It could be a loved one, your health, a beautiful sunrise, or even a small blessing that often goes unnoticed.

Try Heart-Focused Breathing

Slow, relaxed breathing can help balance the nervous system and promote heart coherence.

Place your attention on the area around your heart and breathe slowly and comfortably for several minutes.

Many people find this practice calming almost immediately.

Spend Time in Nature

Nature has a remarkable ability to calm the nervous system.

A walk on the beach, time in the woods, or simply sitting outside can help reduce stress and restore balance.

Prioritize Sleep

The heart and brain perform important repair and recovery functions during sleep.

Poor sleep can negatively affect heart rate variability and overall health.

Move Your Body

Regular exercise strengthens both the cardiovascular system and the nervous system.

You don't need to become a marathon runner.

Walking, swimming, cycling, gardening, and other enjoyable activities can all make a difference.

Nurture Meaningful Relationships

Human connection plays a powerful role in emotional and physical health.

Positive relationships help support nervous system balance and overall well-being.

Maybe We Should Listen to Our Hearts After All

I find it great that science is confirming what many ancient healing traditions have suggested for centuries, which is that the heart is much more than a mechanical pump.

The heart possesses its own complex nervous system. It communicates continuously with the brain. It influences emotions, stress responses, and even aspects of perception and decision-making.

While researchers are still uncovering exactly how these systems work together, one thing is becoming increasingly clear: the heart and brain function as partners, and that the heart may be even more powerful than the brain!

This is why practices such as gratitude, compassion, prayer, meditation, and emotional healing can have such profound effects on our well-being.

So…the next time someone says to you, "Follow your heart," remember that it’s something real for you to do!

Here’s to sending you warm-hearted feelings with a smile on my face!

If you’d like to get a feel for how the body is talking to us in very unique ways, you can watch this video of the first 17 minutes of my doing a keynote presentation for a group. I think this will amaze you as much as this information about your heart.

Modern Diets and Autism: Are We Looking in the Wrong Place?

Autism rates have increased dramatically over the past several decades.

In the 1960s and 1970s, autism was estimated to affect just a few children per 10,000. Today, the CDC estimates that approximately 1 in 36 children in the United States is identified with autism spectrum disorder (ASD).

That is a staggering increase.

The standard explanation is that better awareness, broader diagnostic criteria, and improved screening account for much of the rise. There is certainly truth to that. Children who may have been overlooked decades ago are now more likely to receive an accurate diagnosis and support.

But many researchers believe that explanation does not tell the whole story when the numbers increase to 1 in 36!

Could environmental factors be contributing as well? More specifically, could the dramatic changes in our food supply be affecting the developing brains of future generations?

A growing body of research suggests we should not dismiss the possibility and with my background with a PhD in Holistic Health Sciences I would say this area is a major factor in the spread of ASD.

The Food Experiment Nobody Talks About

Think about what your great-grandparents ate…their diets included butter, eggs, cream, lard, tallow, meat, vegetables, and food prepared from scratch.

What they did not have were the industrial seed oils that now dominate processed foods. Today, soybean, corn, canola, sunflower, and other vegetable oils are found in everything from salad dressings to restaurant meals and packaged snacks.

Most people consume them every day without giving them a second thought.

Yet from a historical perspective, these oils are relatively new additions to the human diet.

A Study That Raises Important Questions

A recent study published in Psychiatry and Clinical Neurosciences examined umbilical cord blood and found that elevated levels of certain metabolites derived from arachidonic acid were associated with greater autism symptom severity later in childhood.

One compound, called diHETrE, stood out (good luck pronouncing that word!).

This is what is called an inflammatory metabolite and children exposed to higher levels of this substance during fetal development appeared more likely to experience greater challenges related to ASD symptoms.

To be clear, this study does not prove that seed oils cause autism.

What it does suggest is that compounds produced from certain dietary fats may influence neurodevelopment during pregnancy.

Why Fat Quality Matters

To answer this, we need to turn to the omega-6 fatty acid linoleic acid which is abundant in modern seed oils. While linoleic acid is an essential nutrient, the amount consumed today is dramatically higher than what humans historically ate.

As a matter of fact, researchers estimate that linoleic acid intake has increased more than tenfold over the past century. When we consume linoleic acid, it can be converted into arachidonic acid which helps produce compounds involved in inflammation and immune function.

Inflammation itself is not bad. We need it to train our system for when it needs to defend itself.

The concern becomes whether excessive inflammatory signaling during critical periods of development could influence long-term health outcomes.

Because the developing brain is especially vulnerable during pregnancy, researchers are increasingly interested in how maternal nutrition and inflammation affect fetal brain development.

Autism Is a Complex Puzzle

Autism is strongly influenced by genetics. Researchers have identified numerous genetic variations associated with autism risk.

At the same time, genetics alone cannot explain why autism diagnoses have risen so dramatically over a relatively brief period.

This is why many scientists are exploring interactions between genes and environmental exposures, including nutrition, toxins, metabolic health, gut health, and inflammation during pregnancy. All of these factors can impact when genes turn on or off.

So, the reality is that autism is likely influenced by multiple factors working together and that maybe Grandma was onto something!

Plus, Grandma didn’t have to be concerned about eating organic or conventional foods since everything was organic in her time.

Modern research seems to bring us back to traditional foods, such as eating:

• Butter
• Eggs
• Whole milk
• Homemade soups
• Slow-cooked meats
• Farm-fresh foods

Were their diets perfect? Of course not.

But they consumed far fewer ultra-processed foods and significantly lower amounts of industrial seed oils.

The Bottom Line

If you’re wanting to become pregnant or are pregnant, the smart thing to do would be to eat like your great grandma did.

If you have children, you want to feed them that way, too, since these highly processed foods can affect children in all kinds of ways. You don’t want to be looking back and saying to your kids…oops…you want to be able to say we did our best to protect you!
