In my work as a specialist physician, I hear this sentence again and again. Patients show me bags full of capsules, powders, and shots — and are disappointed that subjectively nothing has changed. This is rarely due to the users' discipline. It is almost always due to the format.
Anti-aging active ingredients such as curcumin, NAD+, resveratrol, or coenzyme Q10 have a common problem: they are sensitive. They only survive the journey through stomach acid and first-pass liver metabolism in small proportions. What says '1,000 mg' on the label often only reaches the bloodstream as a fraction of that.
This page is my attempt to honestly categorize the topic — and to show why a different dosage form is the decisive lever, not a higher dose on the label.
