Vitamins

This page holds every vitamin in the catalogue, and no vitamin sits outside it. Strengths and counts are shown as printed on the manufacturer's label, which matters most for vitamin D3, where the same brand sells 1000, 5000, 10000 and 50000 IU under near-identical packaging.

By vitamin: Vitamin C in plain, buffered and rose-hip forms; Vitamin D as cholecalciferol, alone or paired with K2; Vitamin E; Vitamin K including MK-7 at 100 and 300 mcg; and Vitamin B, which covers methyl B12, methylfolate, biotin, niacinamide, pantothenic acid and B-complex. If you would rather take one product than several, Multivitamins holds the daily formulas for men, women and over-50s.

Two related pages are worth knowing about: Minerals, since several vitamin products are sold paired with zinc or magnesium, and Immune Support, where vitamin C, D3 and zinc are grouped by purpose. Brands include NOW Foods, Life Extension, California Gold Nutrition, Jarrow Formulas, Centrum, Doctor's Best and Nature's Truth.

A multivitamin and a single-vitamin product are not the same thing and are not interchangeable. A multivitamin supplies several nutrients together, each in a smaller amount; a single-vitamin product concentrates on one. Eleven of the products here are multivitamins and the rest are single nutrients — vitamin B, D, C, K and E — so the first choice to make is which of the two you are looking for.
