Vitamins and Minerals
Reviews of individual vitamin and mineral supplements for UK buyers — multivitamins, vitamin D, vitamin B12, zinc, iron, and the other single-nutrient products that come up most often when a deficiency, rather than a specific health goal, is the starting point.
Dosing conventions and forms (methylated versus standard B vitamins, different iron compounds, vitamin D3 versus D2) vary more than most buyers expect, and matter for both effectiveness and side effects — each review covers the specifics rather than assuming one form fits everyone.
