Glad I am signed up for delivery from Walmart.

This was a substitute for magnesium glycinate to help me sleep at night. ( live over a bar) and to help me ease up with the stresses from work. Need was effective and no side effects, no bloating or loose stools.. AND I am very pleased with the delivery from Walmart. Lke the rest of the universe fI've used AMAZON PRIME for years. You may not have all the products I order on line but you have most.. So thanks!

My chill pill

L-Theanine helps to keep my mood in balance. L-Theanine takes the stress out of drinking coffee and keeps me relaxed and focused. Nutricost provides a pure product at a reasonable price.
