Healthy Aging Supplements: Reviews by Dr. Bell

Healthy aging is less about adding years and more about keeping function as you age. The systems that age fastest — mitochondria, cellular cleanup pathways, hormone production, cognitive sharpness — are also the ones most responsive to good support. Most people do not need to optimize aging in their twenties. By the late thirties and forties, the math starts to shift.

Supplement support here clusters around a few well-studied targets: mitochondrial health (CoQ10, PQQ, NAD+ precursors like NMN and NR), cellular cleanup pathways (autophagy and senolytic support), antioxidant defense (glutathione, vitamin C, E, selenium), inflammation control (omega-3, curcumin), and hormone balance support. Different targets matter at different ages, and some are better used cyclically than continuously.

This page collects every Designs for Health healthy aging supplement I have reviewed — what it is for, the research behind it, who tends to do well on it, and dosing in clinical practice. None of these replace sleep, exercise, or eating real food — the foundations age you faster than anything else if they are missing. If you are on prescription medication, several products in this category interact with drug metabolism, so always check with your provider before starting.
