BulkSupplements.com L-Theanine Powder - L-Theanine Supplement, L-Theanine 200mg - Amino Amino Supplement, Pure & Gluten Free, 200mg per Serving, 100g (3.5 oz) (Pack of 1)

L-Theanine is an amino acid that is naturally found in green tea. Green tea is widely reported as being very healthful and is found in the form of an extract in everything from power bars to ice cream these days. This is because green tea is a source of polyphenols which have antioxidant properties, keeping healthy cells from being damaged by harmful outside sources like free radicals. Since green tea in America generally has less than 10mg theanine in it, very few people actually see its effects in action. This supplement is a better source.
