How Your Gut Controls Magnesium Absorption: The TRPM6 Channel and What Form Actually Matters
Your gut's TRPM6 ion channels regulate magnesium absorption based on body status, upregulating when depleted and downregulating when replete. While…
Krill Oil vs Fish Oil: What the Evidence Shows About Bioavailability Claims
Krill oil is marketed as two to eight times more bioavailable than fish oil, but direct comparison studies with matched…
Magnesium Supplement Claims vs. Evidence: What the Science Actually Shows
Animal studies show tissue-specific magnesium uptake, but human trials have not replicated these findings. Multiple magnesium forms demonstrate similar cognitive…
Functional Mushrooms: What the Evidence Actually Shows

Why creatine works in muscle but not the brain—yet
Creatine supplementation raises muscle creatine by 20–50% in days, but brain creatine increases by only 4% due to the blood–brain…
Why Spinach Iron Doesn’t Count Like Meat Iron: The Bioavailability Gap
A cup of spinach contains 6 mg of iron but only 2–20% is absorbed, while beef's 2.5 mg iron is…
