Theanine Overview
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.
Zanamivir Overview
-
Zanamivir is used in adults and children at least 7 years of age to treat some types of influenza ('flu') in people who have had symptoms of the flu for less than 2 days. This medication is also used to prevent some types of flu in adults and children at least 5 years of age when they have spent time with someone who has the flu or when there is a flu outbreak. Zanamivir is in a class of medications called neuraminidase inhibitors. It works by stopping the growth and spread of the flu virus in your body. Zanamivir helps shorten the time you have flu symptoms such as nasal congestion, sore throat, cough, muscle aches, tiredness, weakness, headache, fever, and chills.
