Performance and Quality
Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
The Pure Encapsulations Magnesium Citrate is a very good product. I am a senior woman and is struggling with low bone minerals and strength. I found this product to be very good for my bone health, helping to strengthen the bone and bone density as well it helps with blood pressure stability, and can help with maintaining heart health, and it works well as a supplement for constipation and other digestive issues.

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.

This is an excellent supplement, I highly recommend it. I can feel the changes after just a couple of weeks of using it. It's very effective in helping me fall asleep after trying lots of different things
