CLEAN Supplement w/Positive Benefits
Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
Very PURE supplement. No extremely nasty fillers or chemical compounds which is hard to find today on the market. I feel as though it's helping slightly with my energy levels, with Mag. Malate being the key. I take one every morning on an empty stomach with a probiotic and 24oz of water. Then a Mag. Glycinate at night to encourage sleep. The combination of these two Magnesium's have encouraged more regular bathroom visits for me when consistently taken (do not exceed 400mg-500mg or severe laxative effects can take place). It is a larger pill but I have not had issues with swallowing- as I can have with others. Yes, a bit more costly than similar types but this brand focuses on main ingredients. Will buy again! Impressed with the company's quality and transparency.

Finally Found a Magnesium That Works Without Side Effects
Size: 180 Count (Pack of 1)
I started taking this magnesium because I was dealing with frequent leg cramps, especially at night, and it has made a huge difference for me. Since using this brand consistently, my cramps have almost completely disappeared and my muscles feel much more relaxed. Another thing I really appreciate is that it does not upset my stomach or cause diarrhea like other magnesium supplements I tried before. After testing several brands, this is the only one that has worked well for me without uncomfortable side effects.
