L-theanine is the only brand of l-theanine that relieves my anxiety. It sedates the mind-talk and calms down feelings of anxiety. Helps me with my insomnia. The only downside is that the calming i feel from it doesn't last more than 2 hours.

This product does not disappoint. This product was recommended by my hormone doctor as part of my nighttime routine. Will continue using this brand. It's pricey but worth every penny.

This is nowhere close to being as effective as something like caffeine. Caffeine causes a stimulating effect, whereas this is supposed to cause a relaxation effect yet doesn't.

Review is feedback from user of product. Saves a bundle, works just as well. It's worthy the money you spend because you can feel the results.

I recommend these supplements to anyone who has energy/sleep/ stiffness issues. Berg recommends increasing potassium to decrease insulin.

It dissolves just fine in filtered water from the fridge. It takes a bit of stirring, but it'll eventually all dissolve. Add all of the above to a blender and blend with 1/2 to 1 cup of ice.

No more cramping. The taste isn't great, but it blends very well. I workout often and find myself getting muscle cramps alot.
