Intolerance of Oral Iron.

Iron is an essential nutrient to life, but oral iron supplements have long come with a reputation for debilitating side effects such as constipation, bloating, and nausea. It is estimated that 8/10 people who take iron supplements report side effects¹, with 50% stopping taking their supplements entirely².

Active Iron is different.

Active Iron’s non-constipating formula helps avoid gut irritation from iron and is clinically proven to deliver 2X better absorption of iron sulfate³.

Active Iron - JAY


These iron tablets are absolutely brilliant. For me it has taken 2 weeks to start noticing a difference, no longer do I feel the tiredness or fatigue that I typically would in the afternoon and the extra energy has meant I am now doing things like going to the gym, going for walks - stuff that I would just not have the energy/motivation to do. Absolutely no side effects or constipation. Will continue to buy these from hereon as part of my vitamin intake.

Great product. It was recommended to me by a friend and I said I would try it as I have to take iron regularly but hate the side effects. I can take this product on an empty stomach and at any time of the day. Have already purchased my next month's supply 🙂 Would definitely recommend this particularly if iron is part of your daily routine!

This was definitely the best iron supplement I ever took. My energy levels improved and I really felt great. They really have changed my life, and can't praise them highly enough.
