A need supplement for every person.
25 April 2024iHerb Customer

originally posted on iherb.com

Such supplement ist absolut need things for everybody. Magnesium peroxide is a compound of magnesium+ oxygen. The laxative effect is due to the magnesium. It ensures that more water enters the intestine due to osmotic effects and liquefies the stool there. This can then be removed more easily. The dose of tablets (500 mg) is optimal for daily use of one piece. There are 180 tablets in a package, which will last for 6 months. Thus, price + quality + quantity = obvious advantages for consumers.

Essential for Helping Me to Naturally Manage Digestion
28 November 2023iHerb Customer

originally posted on iherb.com

This is a reliable supplement that helps me manage IBS / IBD, and maintain my desired digestive wellness. It helps me to remedy and regulate my movements with gentle ease, and as such provides unexpected mood benefits (confidence, trust). Ingredient (magnesium oxide) is good quality, performing as expected if not exceeding expectation with the amount of relief it offers - while I don’t take it for joint / muscle / sleep or hormone concerns, there’s no question this mineral does offer multiple benefits. Tablets are average in size with zero taste, packaging is as expected and dosage is easy. My one drawback are the fillers, but I know those can’t be helped with a product like this.

Poor quality
8 August 2022

Bought the container of180 magnesium oxide tablets. I had to throw away probably 20 or more tablets as they were broken. I had a kidney transplant and magnesium is very important to my health. At the end of the bottle wa a layer of crushed pieces and tablet dust. Will not purchase anything from this company again.

This form of magnesium is not too expensive. Helps with constipation and poor sleep. I take it in the morning on an empty stomach with plenty of water.
