You're getting 350mg of **Magnesium** per serving in the bisglycinate form — one of the best-absorbed forms available, and gentle on your stomach. That dose sits right at the top of the 100–400mg clinical supplemental range, so you're well-covered whether your goal is sleep quality, stress relief, muscle recovery, or heart health. Deficiency is extremely common (estimated in over half the population), and this dose meaningfully addresses that gap.
The formula includes 5mg of **BioPerine** (black pepper extract), which is dosed at the minimum studied level to help enhance nutrient absorption. It's a minor addition, but it supports your body's ability to take in the magnesium more efficiently.
The tradeoff is pill burden — you need to take 4 capsules per serving to reach that 350mg dose. If swallowing multiple capsules daily is an issue, a powder format might be more practical for you at this dose level.
