Theanine Overview

Theanine Theanine, often referred to as L-theanine as that is the predominant isomer of theanine, is an amino acid commonly found in tea leaves, particularly in green tea. It is purported to increase levels of GABA, serotonin, and dopamine in the brain, which can help to reduce stress and anxiety. L-theanine may also promote a sense of calm and improve overall well-being. Some studies have also suggested that it may improve cognitive function, although more research is needed. Most reported drug interactions with theanine are due to its sedative effects.

Tazarotene Overview

  • Tazarotene (Tazorac, Fabior) is used to treat acne. Tazarotene (Tazorac) is also used to treat psoriasis (a skin disease in which red, scaly patches form on some areas of the body). Tazarotene (Avage) is used to reduce facial wrinkling and discoloration in patients who are also using other skin care and sunlight avoidance programs. Tazarotene is in a class of medications called retinoids. It works to treat acne and psoriasis by slowing skin cell overgrowth and decreasing skin cell inflammation, which can lead to acne or psoriasis. It works to reduce facial wrinkles and discoloration by causing an increase in the thickness of the outer skin layers.
