For soothing relaxation that doesn’t make you drowsy, Calming L-theanine is made with L-theanine, an amino acid rich with benefits like increased focus, better immunity, and blood-pressure management. Help tame your anxiety and find calm with every Parsley doctor’s top-recommended stress management supplement.
Found primarily in green and black tea and some mushrooms, L-theanine helps to ease anxiety, stress, and even insomnia. While not snooze-inducing, research indicates that L-theanine could also be beneficial for a good night’s sleep.

What do we mean when we say that Parsley Health supplements are “professional grade”?
Like prescription drugs, supplements are powerful tools whose safety, quality, effectiveness, and relevance should be taken seriously.
At Parsley, our doctors are trained in prescribing high-quality supplements that are indicated to work for the conditions they support, like treating microbial imbalances in the gut, addressing nutrient deficiencies, or balancing blood sugar. We are highly selective and cautious in prescribing supplements, which are formulated with vitamins, minerals, nutrients, and botanicals in their most digestible and effective form. We often find they are more effective than conventional drug therapies alone.
We call Parsley-branded supplements “professional grade” because they’re third-party tested for quality and purity by reliable NSF- or USP-certified manufacturers in the U.S. They are manufactured at cGMP-compliant facilities, meaning the facility must meet requirements set forth by the FDA.
