Suntheanine is a patented, purified form of L-theanine, an amino acid found in green tea. A fermentation process that mimics the natural compound gives it a consistent, high-purity profile.
This amino acid encourages calm, relaxed alertness without drowsiness. People take it to manage everyday stress, sharpen focus, or support sleep quality, often using it before bed.
Take Suntheanine as a capsule or tablet, usually on an empty stomach. Use it as needed for moments of stress, or take it daily as part of a wellness routine.
Most people tolerate Suntheanine without issue. A few may notice mild headaches or digestive upset. Talk to a doctor before starting any new supplement, especially if pregnant, nursing, or taking medication.
