This is a short-term bowel cleanse rather than a daily mineral supplement. The active is **Magnesium** at 1,035mg, delivered as ozonated magnesium oxide and meant to be taken at bedtime over a 7-10 day stretch, not ongoing. The oxide form absorbs at only around 4%, which is the point here: the magnesium that stays in your gut pulls in water and produces an osmotic laxative effect, while the ozonated processing is intended to release oxygen in your digestive tract.
Because so little of that magnesium reaches your bloodstream, you're not getting the heart-rhythm, sleep, or muscle benefits that well-absorbed magnesium forms provide, even though 1,035mg looks like a large dose. The 99mg of potassium, as well-absorbed citrate, sits right at the FDA's 99mg per-dose limit and mainly offsets electrolytes lost during the cleanse; that's roughly 3% of your daily potassium target, so it isn't a meaningful intake source on its own.
If your goal is regularity over a defined cleanse window, this is built for exactly that. If you're looking for magnesium to support heart, sleep, or muscle function, this form and purpose won't deliver it, and a daily glycinate or citrate is the better route for those goals.

Rice FlourFiller
Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.
Citric AcidAcidulant
Natural acid derived from citrus fruits
Microcrystalline CelluloseBinder
Plant-derived cellulose used as a binder and filler in supplements
How to Take It
Best taken in the evening
The Magnesium in it is what pulls this toward the evening. Take it with food — the potassium in it is what makes this kind of product feel nauseating on an empty stomach.
With food
Space it a couple of hours from Iron and Calcium
On the label
As a dietary supplement, take 3 capsules at bedtime, on an empty stomach, with 8-12 oz of water. Use for 7-10 days or until desired cleanse has been attained.
The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.
