What is Suntheanine?

Suntheanine is a patented, pure form of L-theanine produced through a proprietary enzymatic process that mirrors the natural production of L-theanine in tea leaves. Unlike lower-quality L-theanine supplements that may contain D-theanine (an inactive form), Suntheanine is 100% pure L-isomer—the only form shown to cross the blood-brain barrier and deliver therapeutic benefits.

Who It's For

Suntheanine is ideal for adults seeking to manage occasional stress, improve focus during demanding tasks, or support restful sleep without next-day grogginess. It's a favorite among students, professionals, and anyone looking to maintain calm clarity throughout the day.

Suggested Use

Chew 1 tablet 1–2 times daily, or as directed by a healthcare practitioner. May be taken anytime—morning for focus, afternoon for stress relief, or evening to support relaxation before bed.
