What is the difference between pharmaceutical grade mag oxide and non pharmaceutical grade? is this usp?

We were asked by our Dr. to use this particular mag oxide, so we do, from what I have learned, it outsells and outperforms any other mag oxide. So I cannot exactly answer your question, we just think it is the best available.

Are these big ... can someone post pic?

About the size of a regular aspirin. They go down easily and I take two at a time daily.

size and shape of pill? is it smaller than a penny?

Mag-Ox® 400 tablets are very small; only 7/16” in diameter and 1/8” thick! They are also coated so that they are easy to swallow.

Not being Jewish, I don't know specifically the actions that make items kosher. I would suggest that you contact the manufacturer of the product. What I can say about this product which was recommended to me by m Dr., is that I no longer have those loathsome leg cramps. I have been purchasing them on a continuing basis.

GREAT, GREAT PRODUCT

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
