Magnesium and zinc
Magnesium turns up in capsules, tablets, and even gummies, and it supports normal muscle function. Zinc is included in many products for men because it contributes to normal immune function. Both are minerals with real dose ranges, and this is where format matters: a soft chew often carries less magnesium than a capsule simply because of physical limits.
Read the elemental amount, not the compound weight, when a label offers both — that single habit catches more confusion than any other.
