Two capsules give you 500mg of elemental **magnesium** — a full dose that clears the 100–400mg supplemental range and covers the entire 310–420mg daily target on its own, with the evening-meal timing aimed at calm, muscle relaxation, and sleep.

The selling point is the seven different magnesium forms, which is a reasonable idea since each is absorbed through slightly different pathways. Just know it's a proprietary blend, so the split across those seven forms isn't disclosed — the number you can actually verify is that 500mg elemental total, and that's the figure that decides whether magnesium works for you.

One thing to watch: 500mg sits above the 350mg upper limit for supplemental magnesium, the point where loose stools become common. Taking it with food, as the label directs, helps soften that.

How to Take It

Best taken in the morning

Many people prefer B-vitamins earlier in the day; take with food to avoid nausea.

With food
Space it a couple of hours from Iron and Calcium

On the label

Directions: Take 2 capsules with your evening meal.

The label says evening; the ingredients lean morning. Timing isn't strict here — either is fine.

General guidance based on the ingredients, not a substitute for the label or your doctor.
