Tenet for Preventing Heart Disease

From eNewsletter 8/18/2025

DID YOU KNOW that according to new research, monolaurin's antiviral properties are not its only benefit?

Researchers in a Frontiers in Nutrition study found that glycerol monolaurate (monolaurin) improved the integrity of intestinal tight junction protein expression.

Why is this important?

Intestinal tight junction damage, often referred to as "leaky gut," allows harmful substances to pass through the intestinal walls, triggering immune responses and inflammation, potentially leading to gastrointestinal and autoimmune diseases.

This should not surprise us given that glycerol monolaurate (a coconut ester) mimics the immune properties of human breast milk. It is a powerful immune protector.

COVID and Vitamin D

From eNewsletter 8/13/2025

DID YOU KNOW that while this should not come as a surprise to you, a study from PLoS One found that those with insufficient or deficient vitamin D levels were at much higher risk for COVID-19-related hospitalization?

The study followed over 150,000 subjects. Deficient vitamin D levels were considered 24 nmol/L or less, insufficient levels were 25-50 nmol/L, while normal was 50 nmol/L and above.

This is critical because many labs in the United States consider above 30 nmol/L to be within reference range. We have always said between 50-80 is optimal.

Creatine for the Brain

From eNewsletter 8/11/2025

DID YOU KNOW the claim that creatine supplements benefit the brain is misleading and unfounded? Here's why.

Researchers at the Fralin Biomedical Research Institute understood that creatine can benefit the brain when deficiency exists. However, they also understood that creatine as currently comported in supplement form does not cross the blood-brain barrier. The researchers had to use focused ultrasound to direct creatine through the blood-brain barrier.

If a substance does not cross the blood-brain barrier, it cannot affect the brain. Unless supplement manufacturers find a delivery system that can drag creatine through the blood-brain barrier, supplementing with it for brain health is worthless.
