Rated 4.5 out of 5 by 6 reviewers.
Rated 5 out of 5 by great product The product does what it's made for. Excellent quality has are all my purchases from Swanson April 12, 2016
Rated 5 out of 5 by Excellent product This is an excellent intestinal cleanser. I used 2 tsp. in 8 oz. of water with juice of 1/2 small lemon. I had 6 bowel movements within 12 hours. Flushes you right out. I mixed it up using my magic bullet. Worked like a charm. Much much better than the costly product Oxy-Powder (I have used many times) which is nothing more than magnesium oxide January 10, 2015
Rated 5 out of 5 by MgO without additives I appreciate this product, mostly because it is the only magnesium oxide that I've been able to find which doesn't have anything else added to it. I fill my own capsules with it, which is not as convenient as using those which are already filled, but all of the convenient kind have other things added which I do not want to consume. I am so glad that there is still a magnesium oxide product on the market, and hope that Swanson will continue to make it available. I used to purchase my products from Puritan's Pride, and then Lucky Vitamin, but I find that Swanson has the best overall prices and such a good guarantee for customer satisfaction. Keep up the good work Swanson!!! - kamele - Ga, USA November 23, 2013
Rated 5 out of 5 by excellent product I really like this form of magnesium. No large pills to swallow. I put the product on my tongue and take some water; it's quick and easy with no after taste. (Cold water is better). You can also add it to the water first, before drinking it. July 21, 2013
Rated 2 out of 5 by Ick smells bad I thought this magnesium oxide powder would make for an easy routine for me to put in my coffee in the mornings (one less pill to swallow) on my way in to work but it doesnt dissolve completely so Im not sure if Im getting enough to benefit me AND it smells like seawater/seafood/seaweed since its made from oceanic materials. Doesnt taste bad just stinks. Im now looking for capsules instead. May 9, 2011
