Group one: the general daily formula
01This is the most common purchase and the simplest. A base of vitamin C, B vitamins, vitamin D, zinc, and magnesium, in one or two capsules a day. It suits someone who wants a baseline without thinking about it much.
When comparing within this group, look at the serving size and the mineral form first; those two details separate a well-labelled product from a vague one. A label that says how much zinc arrives per serving, and in which form, tells you far more than a front panel promising daily support.
