If you're supplementing B6 for mood, energy, or hormonal balance, this gives you the form your body actually uses. **Vitamin B6** as pyridoxal-5'-phosphate (P5P) delivers 33 mg per capsule, landing squarely within the 25–100 mg clinical range — and because it's already in active form, your liver doesn't have to convert it from standard pyridoxine.

You're also getting 25 mg of **Magnesium** from bisglycinate (TRAACS chelate), a premium form with good absorption. However, 25 mg is a small fraction of the 100–400 mg clinical range — it's more of a cofactor complement than a meaningful magnesium dose on its own.

If you're supplementing B6 specifically for mood support, energy metabolism, or hormonal balance, the active P5P form at this dose is well-positioned. Just don't count on this to meaningfully move the needle on your magnesium intake.
