You're getting 350mg of **Magnesium** per serving in bisglycinate form — one of the best-absorbed forms available, and one that's gentle on your stomach. That dose sits near the top of the 100–400mg clinical range, giving you strong support for muscle relaxation, energy production, and sleep quality. Since over half the population doesn't get enough magnesium from diet alone, this covers a meaningful gap.
The formula includes 5mg of **BioPerine** (black pepper extract) to boost absorption further — right at the studied minimum dose for enhancing nutrient uptake. Four capsules per serving is a moderate pill burden, but the tradeoff is a full clinical dose in a premium form.
The main thing to know: you need all four capsules to get the full 350mg. If you only take one or two, you're getting a fraction of the effective dose and losing the benefit of this product's strong formulation.
