Alpha-galactosidase can reduce gas after beans and crucifers by targeting GOS. Here’s what randomized studies and food-science research suggest—plus where the enzyme won’t help.
foundations
Ferritin often declines before hemoglobin, making it a better early signal of iron deficiency tied to fatigue, brain fog, and restless legs. Learn who may benefit from testing, food strategies, and why ruling out overload matters.

A focused, evidence-based guide to homocysteine as a practical marker of B‑vitamin status and methylation, what affects it, and food-first strategies.
longevity
A focused, evidence-based look at how CoQ10 powers mitochondrial electron transport and cellular energy, with aging, statin, bioavailability, and PQQ context.
longevity
A focused look at how chronic stress relates to telomere length, what mechanisms and trials suggest, and why telomere testing is not a stress gauge.

Resveratrol’s mixed human results may stem from low bioavailability and metabolite complexity. This focused review explains the sirtuin controversy, summarizes clinical evidence, and compares resveratrol with other polyphenols.
mind-stress
A focused, evidence-based look at how supplements may influence deep sleep (N3) and REM, and how they compare with CBT-I for lasting sleep improvements.

A focused guide to exercise-associated hyponatremia in endurance athletes — what it is, who’s at risk, the sweat science, when sodium and ORS may help, and how to avoid overdrinking.
longevity
A focused review of what the NIA Interventions Testing Program (ITP) reveals about rapamycin’s lifespan effects, how it intersects with caloric restriction via mTOR, early dog and human data, risks, and natural modulators.
mind-stress
A focused look at fermented foods as proto‑psychobiotics. Evidence on Lactobacillus/Bifidobacterium strains, the vagus nerve, and traditional ferments like kimchi, kefir, and miso—and what this may mean for mood.
performance-recovery
Research-backed look at beta-alanine for 1–10 minute high-intensity efforts, how it buffers muscle acidity by raising carnosine, key meta-analyses, side effects, and ISSN guidance.
gut-immune
A focused look at molecular mimicry—how gut microbes and infections may trigger autoimmunity—and what current evidence shows across conditions like T1D, RA, and thyroid autoimmunity.
foundations
Vitamin C’s lesser-known job: cofactor for collagen-building enzymes. Learn how this shapes skin health, joints, and wound healing, what the evidence says, and how traditional sources like amla and acerola fit in.
gut-immune
A focused, evidence-based look at when digestive enzymes truly help food intolerance—lactase, alpha-galactosidase, and sacrosidase—versus where marketing outpaces data.
foundations
Ferritin often reveals iron deficiency before anemia develops. Learn why ferritin outperforms hemoglobin for detecting non-anemic iron deficiency, how symptoms like fatigue and restless legs relate, and how to interpret ferritin in context—plus traditional food strategies and overload cautions.
