Magnesium Glycinate + L-Theanine

About Magnesium Glycinate

That’s why Pure Lab’s Magnesium Glycinate + L-Theanine combines our best-absorbing, bowel-friendly magnesium formulation with l-theanine in a 2:1 ratio to provide synergistic relaxation benefits.

Each capsule of Pure Lab’s Magnesium Glycinate + L-Theanine contains our trusted original magnesium glycinate formulation, providing 150 mg of elemental magnesium. With this highly bioavailable formula, less stays unabsorbed, reducing the chance of bowel disturbance while achieving higher blood levels of magnesium to relax muscles and mind.

Each capsule of Pure Lab’s Magnesium Glycinate + L-Theanine contains 75 mg of l-theanine—the secret ingredient for stress. Originally discovered in green tea, l-theanine supports relaxation – calming the mind without causing drowsiness. That means that unlike certain drugs and natural health products, Pure Lab’s Magnesium Glycinate + L-Theanine can be taken any time of day or night. The formulation is also safe to take by individuals using anti-depressants and sleep pills.

Since Pure Lab’s Magnesium Glycinate + L-Theanine supports muscle function and relaxation, it can benefit individuals who have stress, sleeping difficulties, nervousness, muscle spasms, “busy brain” or lack of concentration.
