Active men can take one multivitamin after a full meal, like lunch, for better absorption. Pick a supplement with key nutrients like vitamins A, C, D, E, D3, B12 B-complex, zinc, magnesium, and iron, folic acid, calcium, and omega 3. It supports stamina, focus, and daily strength. Drink enough water and avoid tea or coffee right after. Keep a fixed time every day to take it. Don’t skip meals or double the dose if missed.
