Magnesium and muscle function
Magnesium is involved in normal muscle function and energy metabolism, which is why it shows up in formulas aimed at active men. Food sources include nuts, seeds, and leafy greens.
Different forms behave differently: magnesium citrate and magnesium oxide are common in capsules, and the element amount on the label is what counts, not the total weight of the compound. If a pack lists several magnesium forms, add the elemental amounts together.
Read it this way
Elemental amount, per daily serving — not the compound weight printed beside it.
