iron

While iron supplements are great for anyone experiencing fatigue and who are low in iron stores, women in particular will want to consider supplementing with it since they do lose some iron each month with their monthly cycle.

In addition, since women generally do not consume large volumes of red meat through their diet and what is consumed is often the first to go on a fat loss plan; this means they fall even lower in iron intake yet.

Vegetarians will also benefit quite a bit from using an iron supplement since they also tend to reduce the amount of iron-rich foods they're consuming in their daily diet.
