Optimum Nutrition Opti-Men Multivitamin FAQ's
Everything you need to know before getting started.



Opti-Men is built specifically for active men — whether you're running, cycling, lifting, or competing at any level. The formula is calibrated for the higher nutrient demands that consistent training creates, going well beyond what a standard grocery store multivitamin provides.
Take 3 tablets with food once daily. Most men find it easiest to take with breakfast to build a consistent daily habit. Pairing with a meal that contains some healthy fat also helps your body absorb fat-soluble vitamins like A, D, E, and K more effectively.
Free-form amino acids are the building blocks that your muscles use to repair and rebuild after training. Most multivitamins skip them entirely — Opti-Men includes 1 gram per serving to give your body an extra layer of muscle support on top of the standard vitamins and minerals.
B vitamins are essential for converting the carbohydrates, fats, and proteins you eat into actual usable energy. Active men burn through B vitamins faster than sedentary individuals because their metabolic demands are higher. The 275mg+ B complex in Opti-Men is calibrated for that elevated output — not the minimum daily value set for someone who isn't training.
The 18 fruit and vegetable concentrates are concentrated whole-food sources of antioxidants and phytonutrients — the naturally occurring compounds in plants that help fight the cellular stress that intense exercise creates. They're an added layer of recovery support that goes beyond standard synthetic vitamins.
