CoreLabs Men's Multivitamin 18-50 bottle front, 21 essential nutrients, iron-free, 120 capsules, two capsules per serving
WHY THIS ONE

Most multivitamins are unisex compromises with iron in them. Most adult men do not need supplemental iron, so this formula has none. What it has instead is twenty-one nutrients in the forms that actually work — active L-5-MTHF folate, P5P vitamin B6, D3 alongside
