Found this from ConsumerLab and have been very satisfied.

I am satisfied with the service I received the shipping time and the product

This is the magnesium compound - magnesium L-threonate - that is absorbed more readily by the human body. And with a subscription it can't be beat! Buy it and try it! Bestvite is the absolute best in quality and service!

Shipping is good. Very Quick.

I am very happy with BESVITE
