Despite the name, this product delivers just 25 mg of **Magnesium** per serving — only 25% of the minimum clinical supplemental dose (100–400 mg). Worse, it uses magnesium oxide, a form your body absorbs at roughly 4%, meaning very little of that 25 mg actually reaches your cells. If you're supplementing magnesium for sleep, stress, or muscle support, this falls well short of what the research says you need.

**Vitamin B6** fares better at 25 mg, landing right at the low end of the studied supplemental range. B6 helps your body absorb magnesium more effectively, and the pairing is clinically recognized — but that synergy only matters when the magnesium dose is meaningful. The B6 here uses pyridoxine, which your liver must convert to the active form (P5P) before your body can use it.

The core problem is simple: you'd need to take 4–16 servings (12–48 tablets) daily to reach an effective magnesium dose, which isn't practical. At the labeled 3-tablet serving, this product is significantly underdosed for its headline ingredient.
