Magnesium Glycinate elemental percent

Original post in this thread

Aldarund · 4 points

I have a bottle of older one and it says 1500mg - 200mg. But as I see right now on images it show as 1600mg - 200mg.

Why its changed and on what elemental magnesium % depends? I though that its depends on form e.g. its same for all magnesium glycinate etc

It's the same as it always has been. Nothing has changed with the raw material itself. We only changed the label claims because of a better understanding of the FDA regulations surrounding things with RDAs, or recommended daily allowances. Magnesium has an RDA, so it is treated a bit differently from a regulation standpoint. The regulations state that you have to be at or above label claims on any random sample. There is no wiggle room. So that means we lowered the label claim to be absolute worst case scenario. The absolute minimum elemental magnesium you would get is 200mg in a 1,600mg serving. We also thought it didn't make sense that we had 800mg capsules with a suggested serving of two (1,600mg), but we had 1,500mg as the suggested on the powder. So we brought them in line with each other. Almost always you are getting more than 200mg elemental magnesium in a 1,600mg dose. That's just our lower limit for acceptance. Most of the time it will be around 220mg elemental per 1,600mg. The FDA doesn't care about most of the time on things with RDAs, though. They care about absolute worst case scenario, which will be what our label claim is on anything with an RDA. It's purely a regulatory thing for label claims.

ETA on when Lithium Threonate will come to fruition?! I am sooooo excited for this and have been checking the ETA’s daily, haha. The last update was 4 months ago. Thanks for all you guys do!

The manufacturer we were working with pulled out on the project, and the other labs we have gotten interested want crazy MOQs. We are still working on it, but it is hard to get manufacturers to take on projects right now
