What is Doctor’s Best Multi-Vitamin? Doctor’s Best Multi-Vitamin provides the full range of vitamins and minerals proven essential for health. It is a vitamin-mineral dietary supplement formulation fully optimized for absorption and utilization by individuals of all backgrounds and lifestyles. Doctor’s Best Multi-Vitamin is solidly grounded in the most current nutritional research, and provides key vitamins and minerals in their safest, best tolerated, and most biochemically active forms. How does it work? The many vitamins, essential minerals, and other important nutrients in Best Multi-Vitamin include: Vitamin A (as retinyl palmitate) is crucial for the integrity of the delicate cell layers (epithelia) that line the intestinal tract, lungs, and sinuses. Vitamin A is also crucial for healthy embryonic development and for the eye to function. Additionally, Vitamin A facilitates the body’s capacity to produce antibodies and new immune cells. Vitamin C (as ascorbic acid) is essential for numerous enzymatic reactions, including the synthesis of neurotransmitters and production of collagen molecules, which strengthen the body’s connective tissues. Humans cannot make ascorbic acid and therefore must obtain it from the diet. Vitamin D (as D3, cholecalciferol, plant source) is important for bone strength and is well established. However, Vitamin D3 is also very important for the body’s other organ systems. This formulation supplies vegan-friendly cholecalciferol at a potency that is safe long-term and respects the need for higher D3 intakes to support optimal well-being. Vitamin E (as alpha, beta, gamma, delta tocopherols) is the major antioxidant protector for membranes, the most dynamic cell zones. It helps protect omega-3s, phospholipids, and coenzyme Q10 against damage. This formulation provides not only the alpha-tocopherol form but also the beta-, gamma-, and delta-tocopherols, to better represent the spectrum of vitamin E present in foods. Vitamin K (as K2, menaquinone-7 or MK-7) is crucial for healthy calcium metabolism and is necessary for integrating calcium into bone and preventing deposition of calcium into blood vessel walls and other soft tissues. Vitamin K2 also supports the generation of energy by the mitochondria within the body’s cells. The menaquinone-7 (MK-7) in Doctor’s Best Multiple has high measured K2 activity. Thiamin (Vitamin B1) is essential for the body’s cells to make energy and to metabolize amino acids and carbohydrates (including blood glucose). Thiamin is especially important for managing the modern high-carbohydrate diet, which has
