Hi, a friend of mine told me that her fatigue was helped by magnesium injections. I've only tried magnesium supplements but gave up because the taste was vile (these were pure and in tablet form from health shop). I've now bought some Floradix from the health shop but there was another liquid compound suggesting iron and other vitamins eg some of the B vitamins and Vit C were good for fatigue. There is another compound that has Magnesium and Vit D which I was drawn to but this was suggested for healthy teeth and bones, even though I have had a Vit D deficiency in the past. In the end I bought the iron one so will see what impact if any it has on my fatigue, then I could the magnesium one. I just wondered about others' experiences with magnesium.
