The targeted formula for Brain Health...

Jigsaw Brain Boost™ utilizes patented Magtein® Magnesium L-Threonate specifically designed to support brain health.*

Magnesium is critically important for many of your brain's functions such as learning abilities, working memory, and short and long-term memory.*1

The special form of Magnesium used in the new Jigsaw Brain Boost™ -- Magnesium L-Threonate -- has been clinically tested and shown to permeate the blood-brain barrier, which enhances the receptors involved in supporting healthy short-term & long-term memory, and improves learning abilities.*

Each serving of Brain Boost contains 144mg of elemental Magnesium that is quickly released into the bloodstream to fuel your brain.*

Since your body requires a minimum of 400mg of Magnesium per day, we recommend using the Jigsaw Brain Boost™ in conjunction with our top-rated MagSRT® to give your body ample supply of magnesium while fueling your brain with this targeted formula.*
