Its portfolio of 35+ formulas centers on a patented AM + PM two-tablet dosage system and the flagship VitalFactors NAD+ effervescent formula, with separate men's and women's Fitness Tabs multivitamins and a broad catalog covering joint, heart, immune, brain, and anti-aging wellness goals.

Product overview

MDR offers a portfolio of 35+ doctor-formulated nutritional supplements sold directly to consumers, organized around daily wellness goals including energy and focus, healthy aging, immune support, joint health, heart health, and digestion. The core product line centers on VitalFactors (NAD+ effervescent tablets) and the Fitness Tabs AM/PM multivitamin system (separate formulations for men and women), both built on the company's original patented two-tablet daily dosage approach. These flagship products are supported by targeted add-on supplements addressing specific health concerns — ranging from joint support (Chondro-Pro, Bio H.A. Firm & Flex) and heart health (Active Co-Q10 Ubiquinol, Delta E, OlivOmega, Pristinium) to anti-aging (Longevity Antioxidants, Ultra Pure Resveratrol, MITO-C), brain and vision (Vision Formula, Wild Blueberry & Bilberry), immune defense (OnGuard, Colostrum), and digestive wellness (Tummy PRObiotics, Healthy Tract). Bundled multi-month packages (Year of Health, Year of Vitality, GLP-1 Wellness Bundles) combine the core products with related formulas at discounted prices. All products are manufactured and packed in MDR's Sunrise, Florida facility and carry a 30-day satisfaction guarantee.
