What is Doctor's Best L-Theanine with Suntheanine?
Doctor's Best L-Theanine with Suntheanine is a patented form of the amino acid L-theanine. L-theanine is an amino acid found in green tea that is responsible for the relaxation-inducing effect of tea consumption. L-Theanine with Suntheanine has been shown to promote an alert state of relaxation. This is characterized by an increase in alpha brain waves (signifying a relaxed, alert state) and a decrease in beta brain waves (signifying an awake, excited state of mind). L-Theanine with Suntheanine may improve sleep quality, enhance mental acuity and soothe away tension and nervousness.

Why should I take Doctor's Best L-Theanine with Suntheanine?
Doctor's Best L-Theanine with Suntheanine contains 100% Suntheanine and is best known for its unique ability to promote relaxation without causing drowsiness. L-theanine is one of green tea's natural health-promoting compounds. It is the ingredient that is responsible for both the taste and the relaxing effects of green tea. Research shows that supplemental L-theanine crosses the blood-brain barrier within 30 minutes of intake and thus is able to exert its effects directly on the brain.

Simple but effective
I do like Eucerin products and this night cream is predictably smooth. I haven't noticed any miraculous change in my dark spots but I'm more interested in just keeping my skin soft. A little goes A LONG way so this bottle will last quite a while.

Great sunscreen, easy to use and absorbs well
I would recommend this product because it's super easy to apply and doesn't leave a greasy feeling. The SPF 50 gives good sun protection, and it feels lightweight on my face. Plus, it's hydrating thanks to the hyaluronic acid. Definitely a good choice for daily use, and I like that it doesn't clog pores.

Best face sun protection
My Neutrogena one stung my eyes and made me constantly tear and this is soooo much better. It feels light and dries down well without feeling greasy. Also it didn't make my skin react. A++
