Quick shipping, fair pricing

I was looking for something that was made in the USA...not just packaged in the USA and I came across these magnesium glycinate capsules. They're easy to swallow, and what can I say...they're vitamins. As long as they're made in the good ol USA then I feel good about them and I'm happy!!

Great product

For many years I have taken a different form of magnesium, but glycinate was recommended to me, and so I tried it. It is gentle, yet "keeps everything moving." I take it an hour before bedtime every night. Magnesium is excellent for muscles, nerves, heart, brain..... everything.
