This **Magnesium Complex** spreads its 225mg of elemental magnesium across three forms — glycinate, taurate, and aspartate — covering calm, sleep, and muscle relaxation through several absorption pathways at once. That 225mg sits inside the 100–400mg supplemental range and well under the 350mg upper limit, so it's an easy daily dose to tolerate for sleep and relaxation support.

The form mix is the point here: glycinate and taurate make up about two-thirds of the magnesium, and both are well-absorbed and gentle on the stomach — the forms most studied for relaxation and sleep without the loose-stool effect some magnesium can cause. The aspartate portion rounds it out at a more moderate absorption tier.

Worth knowing: 225mg falls below the 310–420mg total most adults need daily, so treat it as a top-up alongside a magnesium-rich diet, not your whole intake. You'll need all three capsules to reach that 225mg.
