Vitamart's Take
Magnesium and L-theanine are two of the most popular relaxation nutrients, and this formula puts them together in a 2:1 ratio so you don't need two bottles. The magnesium comes from bis-glycinate chelate, which Pure Lab formulated for high bioavailability and minimal bowel disturbance, and the L-theanine is non-drowsy, so you can take it three times a day, as the label directs, without feeling sleepy. Pure Lab also notes it's safe to use with antidepressants and sleep medications.
How Pure Lab Magnesium + L-Theanine Compares
Magnesium + L-Theanine vs. Magnesium Glycinate 165 mg

Magnesium + L-Theanine vs. L-Theanine Chewables
Pure Lab L-Theanine Chewables give 125 mg of L-theanine in an orange-flavoured tablet, with no magnesium. Choose this capsule if you want magnesium for muscle function as well.

Pure Lab also makes an unflavoured Magnesium Glycinate Powder. It's magnesium only; this capsule adds L-theanine and needs no mixing.
