Not very effective at all
I don't know if it's just me but I found the Biotrace Magnesium Citrate to be quite disappointing, almost completely ineffective and I will not purchase again. I take Magnesium Citrate at night to help me sink into a deep sleep. I was quite used to the Solgar Magnesium Citrate, which I find to be excellent, except this product now seems impossible to get, so I've been forced to try other brands. But I won't be trying Biotrace again. BIOTRACE COMMENT: Magnesium is required for many different actions in the body such as bone formation, detoxification, metabolism, relaxation and to assist sleep. A form of magnesium that may be helpful for relaxation and sleep is BioTrace Magnesium Bisglycinate. The magnesium is bound to two glycine peptides and glycine has a calming and relaxing effect on the body.
