I've been using the Natural Calm in the canister for years as a magnesium supplement. In the beginning, I used it to help with migraines, but now take it for general health since many of us are magnesium deficient. If you told me I could only keep one supplement, this might be it! I prefer the Raspberry-Lemon, as the plain lemon is a bit tart for my taste. I recently purchased the packets for travel and found the individual packets to be sturdy to hold up to the rigors of travel and easy to open. This product is also Non-GMO Project Verified. Buy the canister for home use as it's more cost effective.
