I think this is a great product. I have tinnitus, and the sound is greatly reduced when I take the magnesium. I'm very pleased! Thank you. Margaret Dube

The products are great, but the processing and shipping takes way too long! I’ve ordered several times & it took three days to process and ship AFTER order placed and another 8 days to receive. So, 11 days after my order was placed, I finally got my order. Too long. There should be options available for faster shipping. And disappointed it takes 3 days to fulfill order to even ship.

Excellent product. They have definitely made a difference in my digestion, hands down. I've tried many different digestive enzymes that never took away the piling up of food in my gut. They actually have helped me greatly improve my bowel movements. Thanks much!

Great product! It helps a lot with the quality of my sleep and keeps me calm during the day. Will definitely continue using.
