Floravit is something I have been using for years. It helped to keep my iron levels up. I usually take it in spring and in autumn. I have been giving it to my kids, too as they have been growing up on vegetarian diet. What I like about it is that it comes from natural sources and it is in a liquid form. It tastes fruity but has bit of a metallic taste. I don’t mind that at all and kids take it with little bit of juice. Once opened it needs to be kept in the fridge. It is bit pricey but it is worth it. In the reviews of the product I read that people take it when their immunity is down or when they feel tired. Most of the reviews I came across were positive. When I hear that somebody is anemic or when my friends are pregnant I tell them about this. As a bonus it contains Vitamin B12 and is gluten free. If you need some iron boost then check it out!
Update 2019: I am still relying on Floravit and Floradix. I think it absorbs well and does not cause constipation as most of the iron supplements. Tastes O.K. I do a course every three months.
