EndurPro, Suntheanine® SR, 200mg, 90 Tablets

Suntheanine SR is a dietary supplement featuring patented Suntheanine® L-theanine and formulated to support calmness, mental clarity and cognitive function. The SmartMatrix™ sustained-release tablet releases L-theanine gradually - over 6 to 8 hours - for both immediate and long-lasting support. Since L-theanine has a similar structure to glutamate and can bind to glutamate receptors in the brain, researchers believe this is the main action responsible for its ability to help the body manage stress and reduce its negative effects. After ingestion, L-theanine has the ability to cross the blood-brain barrier from 30 minutes up to 5 hours.
