I started taking this product for ongoing ibs (D C) as well as benefits in more naturally reducing anxiety tied to ADHD. This product came quickly, was well packaged with appropriate seals and was easy to take. The size of the pill and lack of taste made this an easy addition to my vitamin regimen. Within days I noticed a huge difference in water retention (as the idea is that magnesium pulls stored water to the bowel to ease of passing food). I literally fit in jeans a size down I had not worn for a year. I found myself thirsty but given the excess water loss I was not surprised. Surprising was the colon cleanse aspect of the vitaminâ€" especially the first few days be close to home as you may use the bathroom more frequently than normal and without as much warning. Within 3 to 4 days this went away. I did notice my anxiety was considerably less within this same 3 to 4 day period which allowed me to fall asleep much faster. An unexpected and incredibly welcomed benefit was the fairly immediate reduction of a appetite!! I am a snacked especially working from home and I now have to remind myself to eat! This makes sense as your body better absorbs the nutrients in food! Highly recommend
