iHerb Customer Reviews

Decent bio-availability. Good, reliable product

Posted by 5702615038509124220 on Jan 14, 2017 | Verified Purchase

My body reacts well to this product, and I see the results in my nails and other such indicators... therefore, I deduce that it has decent bio-availability. The caps are easy to swallow. I would give this a 5 star rating if it were made in a higher dose cap, as then I wouldn't need to take as many to obtain the prescribed dosage for my needs. I have used this product for some time now and feel that from bottle to bottle, the quality remains consistent. Good, reliable product

Magnesium 400 mg helps keep my body in balance!

I recently read an article by a local nutritionist that most people are lacking in magnesium and the conditions it may affect to keep the human body functioning properly. Sure helps by improving energy, digestion, body tensions, nervousness, and irritability, to mention just a few.
