Understanding L-Amino Acids vs D-Amino Acids: Essential Building Blocks of Life Amino acids are the fundamental components of proteins. Except for glycine, each exists as two non-superimposable mirror images (enantiomers): an L- form and a D- form. These mirror images can behave very differently in biology. The molecular mirror: what L and D actually mean L/D notation does not equal “levo/dextro” optical rotation. L and D are assigned by comparing a molecule’s configuration (in a Fischer projection) to that of reference D-/L-glyceraldehyde. Some L-amino acids rotate plane-polarized light to the right (+), and some D-amino acids rotate it to the...

The Hidden Dangers of Synthetic Multivitamins: Why Whole Foods Reign Supreme It’s tempting to reach for a “catch-all” multivitamin, especially when hunting for the best multivitamin for men over 50. Reality check: supplements can help, but they’re not a panacea—and synthetic, isolated nutrients can behave differently in the body than nutrients packaged by nature in food. The Synthetic Dilemma Many popular multis rely on lab-made (synthetic) nutrient forms. Molecules can be chemically identical yet differ in isomer mix, cofactor context, or dose. Evidence on “synthetic vs. natural” bioavailability varies by vitamin: for some (e.g., vitamin C), trials show similar uptake;...

Kayla Barnes-Lentz’s Longevity Protocol: A Woman’s Guide to Living to 150 Kayla Barnes-Lentz, age 33 and co-founder of LYV The Wellness Space, has developed a longevity protocol for women aimed at extending life far beyond current norms. She believes early, disciplined biohacking can shift the lifespan curve. Designing for Women’s Biology Recognizing that many longevity protocols are male-centered, she adapts protocols for women—e.g. doing cold plunges at 55 °F (13 °C) and timing them to the first half of her menstrual cycle to align with hormonal phases. Data-First Mornings She begins at ~5:00 am, accessing metrics from her smart scale...

In recent years, neuroplasticity has emerged as one of the most exciting concepts in brain science, with applications that stretch far beyond cognitive functions. It’s the process that allows the brain to adapt, rewire, and grow in response to new experiences. What many don’t realize is that neuroplasticity is equally important in fitness, playing a crucial role in skill development, injury recovery, and overcoming training plateaus. Let’s take a closer look at how understanding and leveraging neuroplasticity can unlock your potential for greater physical achievements, and why brain training is just as essential as muscle training. The Brain-Body Connection: How It...
