National Academy of Sports Medicine answeredThere is a possibility that you are losing considerable iron during your period. On average, women lose about ¼ cup of blood at each menstrual cycle; women with a heavier flow may even lose more. If you are feeling fatigue and weakness, this might be associated with a temporary drop in iron level associated with your menstrual cycle. Iron can be found in red meats, most legumes (kidney, lima, pinto, navy, black and soybeans), dark greens (collard greens, kale, mustard greens, spinach, and turnip greens) tofu and certain vegetables (broccoli, Swiss chard, asparagus, parsley, watercress, Brussels sprouts). You may want to check with your health care provider to see if taking a supplement is necessary during time of the month.

No, unless you’re not eating healthfully. Most people don’t eat enough fruits and veggies, whole grains and healthy fats, so be sure to include veggies and/or fruit at each meal, a lean protein (skinless chicken, beans, seafood and soy products) and whole grains (oats, brown rice, whole wheat pasta/bread) at each meal. Low-fat milk products or alternatives fortified with calcium and vitamin D are also important for health. Finally, many females, especially adolescent girls do not get enough iron from their diet so in addition to eating healthfully, you should consider taking a quality multivitamin and/or a separate iron supplement if your doctor advises you to do so.
