Magtein Magnesium L-Threonate, 2,000 mg – 120 Capsules

Magtein Magnesium L-Threonate 2,000 mg – 120 Capsules

Magtein (magnesium L-threonate) is a breakthrough form of magnesium developed at MIT that is uniquely able to cross the blood-brain barrier and raise magnesium levels directly in the brain. This makes it the premier magnesium for cognitive support.

By increasing brain magnesium, Magtein supports sharper memory, improved learning, better focus, and healthy brain aging. It is also valued for promoting calm, relaxed sleep — making it a true mind-and-rest supplement.

Each Double Wood serving delivers 2,000 mg of premium Magtein magnesium L-threonate, with 120 capsules per bottle. It is the smart daily nootropic-mineral for adults seeking cognitive clarity and restful nights.

The Double Wood Promise: At Double Wood Supplements, we believe quality and transparency come first. Every product is manufactured in the USA in GMP-compliant facilities, third-party tested for purity and potency, and made with carefully sourced ingredients — so you know exactly what is in every batch.
