Nattokinase Lacks Evidence; Choose Omega‑3 or Berberine

Nattokinase isn’t high on my list for cardiovascular prevention. I don’t see convincing evidence that it should be a primary strategy for cardiovascular disease or stroke risk reduction. If the goal is cardiovascular prevention, there are options with much stronger support. Omega-3...

Higher Omega‑3 Levels Cut Alzheimer’s Risk by Half

Higher omega-3 status is associated with dramatically lower Alzheimer’s risk. People with a high omega-3 index (~10%) have about a 50% lower risk of Alzheimer’s disease compared with those at the low end (~4%). Other studies have reported a dose-dependent relationship -...

Resistance Training Counters Age‑related Muscle Loss and Restores Protein Sensitivity

Muscle loss with age is common, but much of that decline is driven by inactivity, not aging alone. On average, we reach peak muscle mass somewhere between 20 and 30, then lose about 8% per decade after that. By the time...

Urolithin A Enhances Mitochondrial Health and Endurance

I'm fascinated by Urolithin A. It's a compound that stimulates mitophagy (mitochondrial autophagy), helping clear out and replace damaged or dysfunctional mitochondria. Recent studies show that urolithin A improves endurance performance and even keeps immune cells "younger" with age. The data are early...
