Great Supplements. Good prices. Made in the USA
Size: 90 Count (Pack of 1)
I love this company for all my supplement needs. My only complaint about the magnesium supplement is that the capsules are pretty large. If you have a problem swallowing pills/capsules you may have a bit of trouble swallowing these. However, I’ve never had magnesium that was easy to swallow. Most of Pure Supplements are small and very easy to swallow. The magnesium is the exception. All magnesium pills are large.
