Magnesium That Improves Your Brain Function

What Is It?

Magnesium L-Threonate is a unique form of magnesium combined with L-threonic acid, a vitamin C metabolite. It’s been shown to cross the blood-brain barrier and directly increase magnesium levels in the brain.

Why That Matters

Magnesium is essential for over 300 brain and body processes, but most forms don’t reach the brain in meaningful amounts.

Benefits

More connections between neurons = better learning and recall.

Helps your brain adapt, learn, and stay resilient over time.

Supports calm, focus, and mental clarity — naturally.
