Outstanding Review by

I have tried many different brands of magnesium for relaxing muscles (my work is quite physical) and sleep including specifically magnesium-sleep formulas, and this outshines them all. Have ditched all other sleep supplements and now just use this. Great result.

Excellent Review by

Very pleased with the efficiency and speed of delivery. Ethical Mg helps my leg cramps and sleeping and it doesnt cause diarrhoea which is a problem with some other brands Mg products.

I brought this product to eliminate or reduce muscle cramps Review by

Very easily absorbed magnesium, works better than every other over the counter i've tried on my daughter shes has problems absorbing nutrients but not with this one works well.

Found a great brand Review by

In the past I have used a different brand of Magnesium but decided to try Ethical Nutrients on advice, a really good brand. This product is great as it is not so dramatic on the bowel motions. It was always a rush for the loo first thing in the morning. Now I do not need to go so urgently and no cramps in the night.

the jury is out Review by
