Vitamin Demands Of Iron Women

Physically active women are at elevated risk of iron deficiency according to a study published in the American Journal of Clinical Nutrition. Researchers gave half a group of female soldiers engaged in combat training 15 milligrams of iron per day. Women in the other half of this group received a placebo.

When the study began, 14 women in each group were identified as being iron deficient. After the training concluded, there were twice as many iron deficient women in the placebo group (a 100% increase), but only a 35% increase in the supplementing group.

The Bigger Picture: While your workout might not be as taxing as a soldier's, it's important to note that the women who didn't take any iron in the military study posted slower running times than women who supplemented with iron. A high-potency multivitamin with plenty of iron might put more spring in your step on the treadmill.
