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.
