BIOptimizers Magnesium Breakthrough 50 Veggie Caps
Verified Purchase
Magnesium is essential for roughly 300 body functions, and yet somewhere around 60% of Americans are deficient in magnesium. Not good. BIOptimizers 7 forms of Magnesium is good value and the right dosage.

It's fantastic, it's a shame it's out of stock so I can't buy it. I think I'm sleeping a bit better since I started taking magnesium, thanks.

I decided to try these because my usual magnesium is just one kind of magnesium. I like the benefits of them all though, and it's an important mineral to consume. These brand is known for their quality ingredients
