Best multiple has unique positive features not found together in other multiple vitamin-mineral supplements: provides optimal nutrient allowances in just 3 capsules per day. Multiples that recommend taking one or two capsules a day cannot squeeze sufficient amounts into this small mass, and often take "shortcuts". Avoids common "shortcuts" that compromise product quality. For example, it avoids providing magnesium as magnesium oxide, which is known to be poorly absorbed. Unique source for potent plant vitamin d3. Our vitashine d3 is organically prepared from a sustainable plant source and certified by the prestigious UK vegan society. Supplies b vitamins in their best-utilized forms. Most multiples use b vitamin forms ("vitamers") that are poorly utilized. This formulation does not compromise. Omits synthetic folic acid. This artificial folate is poorly utilized compared to other folate vitamers. This formulation supplies fully active folate. Ensures vitamin B12 fully active for dietary repletion. Virtually all multiples provide insufficient vitamin B12. This formulation provides 1000 micrograms of fully active B12 to help ensure excellent absorption.
