Hi there I am still researching. I tried splitting my 20mg ferrous bisglycinate in half and it still made me drowsy and horrible. It clears after three or so hours... is it because it's all going in at once?
Please if you could take a look at this product as I would love to hear your views. Feosol natural release here is the link.
There aren't many papers - this was the most recent I found.
