By midlife, NAD+ and human growth hormone decline sharply. That's why you feel slower, tire faster, and recover less. VitalFactors helps restore both.

"I recommend MDR to my patients who want a clean, physician-designed stack — nothing flashy, just dosed correctly."

"I've been performing for six decades. VitalFactors keeps me feeling like I've got another six in me."

Most customers subscribe — it's cheaper per month, you never run out, and you can skip, pause, or cancel in one click from your account.
Most customers report more consistent energy and better sleep within the first 2–3 weeks. Visible strength, skin, and endurance changes typically show up between weeks 6 and 12. Consistency matters more than dose — that's why we designed VitalFactors as a daily drink rather than a capsule stack.
VitalFactors is built around precursors for NAD+ (including nicotinamide riboside and niacinamide), amino acids that support natural HGH (arginine, ornithine, glutamine, glycine, lysine), plus key vitamins and minerals. Full Supplement Facts are on every bottle and on the product page.
MDR formulas are food-grade nutritional supplements, but any new supplement can interact with medications — especially blood thinners, blood-pressure medication, and diabetes medication. Bring the Supplement Facts panel to your doctor before adding it, and we'll honor the 90-day guarantee if your physician recommends you stop.
Nothing beyond the current month. Skip a shipment, change the frequency, or cancel entirely from your account page in one click — or email us and we'll do it for you. No phone tree, no retention scripts.
