Strength training and brain health belong in the same sentence, and the research finally supports saying so. Most people lift for muscle, bone, or appearance, and they never hear what the cognitive trials measured. Others hear an exaggerated version, in which a barbell becomes insurance against dementia. This article reports what researchers measured, in whom, and where the findings stop. It also explains how I train myself after decades of drug-free bodybuilding, and what that experience does and does not prove. You will finish knowing what to expect from a barbell and what to expect from a bottle.

Strength training and brain health, graded honestly. A researcher and lifelong lifter reports what the human trials measured, and in whom.

☀️ Vitamin D: More Than Just Bone Health!

Did you know vitamin D acts more like a hormone than a traditional vitamin?

It plays important roles throughout the body, supporting:

🦴 Bone and muscle health
🛡️ Immune system function
🧠 Brain and nervous system health
❤️ Cardiovascular health
🧬 Regulation of many genes and cellular processes

Dr. John E. Lewis emphasizes that vitamin D is involved in far more than we often realize!

💚 Are you keeping track of your vitamin D levels? Ask your healthcare professional whether annual testing is appropriate for you and what level is right for your health.

💚 Behind Every Research Breakthrough, There Are People Who Make It Possible.

Sometimes, the most meaningful scientific discoveries begin with something bigger than science: the generosity and compassion of others.

In a recent conference presentation, Dr. John E. Lewis shared the story behind how his Alzheimer's research began.

An opportunity arose to conduct a clinical trial specifically involving people with Alzheimer's disease. The opportunity came about because one family, personally touched by this devastating disease, wanted to make a difference.

Their generosity helped make the research possible.

Dr. Lewis reflected that without this family's willingness to support the study, he might never have had the opportunity to conduct this important research.

Think about that for a moment.

Behind every research study are people. Families who have experienced loss. Loved ones searching for answers. Individuals who choose to turn their personal struggles into an opportunity to help others.

🌱 Research doesn't happen in isolation. It takes generosity, collaboration, dedication, and people who believe that tomorrow's answers are worth pursuing.

To the family who helped make this Alzheimer's research possible: thank you. Your generosity has contributed to a greater understanding of brain health and the ongoing search for new possibilities.

At Dr Lewis Nutrition, we are reminded that science moves forward because people care.

💚 Sometimes, one family's desire to help can make a difference far beyond their own.

How to increase acetylcholine naturally is a question I hear from people who feel their recall slipping. Acetylcholine is the signaling molecule your brain leans on for attention and memory formation. Most articles on the subject list supplements and stop there. This article does something different. I explain what acetylcholine does, where the raw material comes from, and what human trials have measured. You will learn which foods supply choline, how much you need, and where the evidence runs thin. You will also see why I put sunflower lecithin in Daily Brain Care.

How to increase acetylcholine naturally: what choline does in the brain, which foods supply it, and what the human trials actually found.

Vitamin K2 MK-7 is sold by the microgram, and most dosing pages answer with a number and give no more information. Shoppers see 45, 90, 100, 180, and 360 micrograms on competing labels with no way to judge between them. Those numbers are not arbitrary, and they are not clinical recommendations either. Each one traces to a trial that measured a specific marker in certain people. This article explains where the trial doses came from and what the researchers measured. It also covers the form question, the food sources, and the interaction that matters most. You will finish this article able to read any MK-7 label and know what its number means.

🌱 Can Nutrition Help Activate Your Body’s Natural Repair Systems?

When you hear “stem cells,” you might think of medical procedures for joint pain. But researchers are also exploring how nutrition may influence the body’s own cellular and immune processes.

🔬 What did Dr. John E. Lewis discuss in his research?

In a study involving people with Alzheimer’s disease, researchers reported a **286% increase in CD14+ cells** over 12 months, alongside changes in immune markers and inflammation.

🧬 Why is this interesting?

• CD14+ cells are immune cells involved in processes that interact with stem cells and tissue repair.

• The immune system plays an important role in maintaining the body’s normal functions.

• Researchers are investigating whether specific nutritional compounds may help support these biological processes.

💚 The bigger picture: Nutrition is about more than vitamins and minerals. Understanding how food-derived compounds interact with our cells may help researchers uncover new possibilities for healthy aging.

Important: CD14+ cells are not themselves a direct measure of stem-cell production. These findings do not prove that nutrition increases stem cells, regenerates joints, or reverses Alzheimer’s disease.

At Dr Lewis Nutrition, we believe good science starts with asking questions, examining evidence, and understanding what research really tells us.

EGCG benefits are claimed on nearly every green tea supplement sold, and almost none of those claims comes from human trials. Most of what you read goes back to laboratory work on cells rather than to people who swallowed a capsule. The compound is real, the chemistry is real, and the absorption problem is real as well. I will show you what researchers have measured in people and how little of an oral dose reaches your bloodstream. You will also see why the one change that raises absorption is the change regulators warn against. Knowing both halves lets you judge a green tea product on evidence rather than packaging.

EGCG benefits come mostly from cell studies. Human absorption is poor, and the one change that raises it also raises liver risk.

🌿 Why Do We Take Aloe Vera Orally?

Aloe vera isn’t just for your skin! Its clear inner-leaf gel contains unique polysaccharides that researchers are studying for their potential effects on digestive health, immune function, and the body’s natural cellular processes.

🧬 Why is it interesting to researchers?

💚 Digestive health: Aloe gel is being studied for its potential role in supporting digestive function.

🛡️ Immune function: Aloe-derived polysaccharides are being investigated for how they may interact with immune cells.

🩸 Metabolic health: Some small human studies suggest oral aloe gel may help improve blood sugar control, but more research is needed.

🔬 Nutrient absorption: Preliminary research suggests aloe gel may influence the absorption of certain nutrients, including vitamins C and E.

At Dr Lewis Nutrition, we’re interested in the science behind aloe’s unique compounds and their potential role in supporting human health.

Remember: promising research is not the same as proven benefits. Choose products made from properly processed inner-leaf gel, with potentially harmful aloe latex compounds such as aloin minimized. Oral aloe can interact with medications and may not be appropriate for everyone.

🌱 Nature offers fascinating compounds. Science helps us understand them.
