Deal Details
Sports Research® Magnesium L-Threonate Capsules 2000mg - High-Absorption Magtein® for Enhanced Brain Health, Memory, Focus & Restful Sleep Support - Vegan · Non-GMO · Gluten Free - 90 Count

Not sure if this is YMMV, but this is on sale, normally $29, currently $24 with Prime Day deal, and then an extra 40% off with S&S, plus the normal S&S discount.

I don't know much about this brand, but it has a lot of good reviews, says manufactured in the US (globally sourced ingredients), 3rd party tested, and GMP certified. But I know that can all be fake.

In for a bottle at this price.

Link takes me to 120 count, at same price after discount. 4 capsules per serving, so this is a month's supply.

What kind of brand is "Teraputics"?!
not to be confused with "therapeutic".

i looked at same listing the other day when searching for Mg L-threonate but felt brand is sketchy (e.g. reading "About" box on the web site)

there is a Malaysian company by that name https://www.facebook.com/profile....9668902841

Can you read what these seals say? I noticed on one of the images of the listing. They look like blurred but on closer look seem Gippity (AI) generated. "SQUGFED FROM A GMP C**TIFIED SOUN*TY"
"VEMETANIAH PDIGRACY PLOSTARIAN EXI**A**"
"THD PARTY TAST80 ADD SAUTE TEST**"
"OLNTEN FREE **UTED FARM"

Our community has rated this post as helpful. If you agree, why not thank iCEifer

For those looking for a more reputable brand with the same Magtein, Life Extension is selling a 30 day supply of the powder for around $18 after 40% coupon on Amazon and the Sports Research one is around $21 for Prime Day. For Costco you can get more than a 30 day supply of the Sports Research brand for cheaper per capsule at any time than both options I have suggested.

This is a great price but limited to just 1. Sometimes where there are no limits you can purchase a large quantity and then cancel once delivered but looks like this is not the case with this one.
This type of magnesium is very expensive due to patents. It is best to take 1 or 2 pills of this for the blood brain barrier and then fill the rest of your needs with Magnesium Glycinate, there is high quality version from Doctor's Best.
