Monthly periods are the most common cause of iron loss, and research shows that women of childbearing age need up to three times more daily iron than men. It is estimated that 220 to 250mg of iron per pint of blood is lost during menstruation.

As a result, many experience tiredness and fatigue¹. A recent survey conducted by Active Iron² shows that 67% of women experience heavy periods. Yet, 41% of women admit they have never considered that their menstrual cycle could be causing inadequate iron levels, resulting in fatigue.


Women can also experience an increased need for iron during perimenopause and menopause, as periods can become irregular and menstruation may be heavier or more frequent. Amongst women who experience heavier periods, adequate daily iron intake is particularly important and may be difficult to achieve through diet alone.

I bought these tablets for my wife, who was really suffering with headaches, dizziness, and nausea every time she has her period. These tablets have worked miracles for her. My sincere thanks to the seller.

This pill has helped me with my borderline inadequate iron levels. I felt a big difference in my period cycle, my fatigue around the cycle had also diminished. The other positive thing around this product is that its gentle on the tummy. As a former chronic gastritis and irritable bowel syndrome sufferer, avoiding an upset or trigger is a must. This really does the trick.

Having used iron tablets before and noticing the side effects after a period of tiredness brought on my stress and exercise I gave these a go. They are very easy to take and can be taken on an empty stomach. I notice a difference in a few days and feel less inclined to nap. I'd especially recommend these for ladies who also get digestive problems associated with their periods.
