160mg per serving (80mg per pill) seems a bit low compared to other brands. Qunol might be a better deal right now: https://www.amazon.com/dp/B0CKGDP...e_0_1&th=1

This had an additional 40% off for me. Thanks.

Edit: it's buffered though meaning it's mixed with mag oxide which is a laxative.

Isn't magnesium oxide unabsorbable? So if that's kind of toward the total would be a negative

Quote from Scoopzpoopz :
Costcos natures bounty glycinate isn't chelated meaning it's not mixed with a cheaper less effective magnesium such as oxide
Chelated means the mineral is bonded to an amino acid or other organic molecule, not that it's mixed with another mineral

Don't confuse 420 mg of magnesium with 420 mg of the compound. Qunol's label specifically says the 420 mg is elemental magnesium, provided by 2 capsules.

Pure magnesium bisglycinate is only about 14% elemental magnesium by weight. So, to get 420mg of elemental magnesium, you'd need ~3,000mg of the compound—about 1.5 grams per pill. Technically possible, but highly unlikely unless those pills are horse-pill sized. Look closely...qunol is buffered, and I'd bet money that it's buffered with oxide to fit more magnesium into a smaller serving.

Neither has any magnesium oxide in them (which, yes, is pretty close to nonabsorbable). The qunol version is absolutely a better deal.

I just started taking another brand of this to help with my sleep a couple weeks ago. It's only 125mg. Don't think I'm sleeping any better, but my blood pressure and blood sugar are down.

Qunol is magnesium glycinate "buffered," which generally means the glycinate is combined with a much higher elemental magnesium source--usually magnesium oxide. I guess you can call it a labeling loophole...that doesn't mean qunol is a bad product, but the "buffered" formulation is a cost-efficient way to achieve a higher elemental-magnesium number than pure bisglycinate alone without disclosing the exact breakdown.

No. This isn't potent enough.
