Nutrient quality
Vitamin D3 and zinc citrate are useful, while synthetic vitamin E, folic acid, and cyanocobalamin are less preferred, and biotin is substantial, but vitamin D, vitamin C, zinc, choline, and inositol are modest. Very high biotin can distort some thyroid, hormone, and cardiac laboratory tests, while the active formula is compact, although tiny choline and inositol amounts add little.
