Magnesium Bisglycinate · 300 mg elemental

UNBUFFERED. UNCOMPLICATED.

Most "premium" magnesium hides cheap oxide behind a big number on the label. Ours doesn't. The dose you read is the dose you get — lab-verified every batch.

The buffer problem

A big number isn't a big dose.

Oxide is cheap to source and heavy on the scale, so it inflates the milligram count while almost none of it absorbs. Here's the gap, in their own numbers.

~20%

of buffered magnesium absorbs

When oxide is hiding in the "other ingredients," most of that 300 mg label is buffer your body doesn't take up.

more elemental, same price

300 mg of real bisglycinate vs. ~60 mg of usable buffered magnesium. Same shelf price, five times the dose that counts.

$0

spent on proprietary blends

No "blend" to hide the ratio. One ingredient, one dose, one certificate of analysis — published.
