Ingredient form and dose
Ingredient form and dose
The first question is what the ingredient actually is. Magnesium oxide and magnesium glycinate behave differently, and a label that only says “magnesium” hides that. We prefer forms with good absorption at a realistic dose, and we publish the amount per serving rather than per batch. If a supplier cannot state the figure, the product does not get listed.
For men’s vitamin supplements, we also check whether a mineral is paired with a form the body can use at the amount stated, not just present somewhere in the blend.
