How Is Jigsaw's L-Theanine By Suntheanine Different?
- Contains 100% Suntheanine, the ONLY pure form of L-theanine on the market — with no impure D-theanine. (Many companies mix the more expensive Suntheanine with inexpensive versions of L-theanine, so they can sell it cheaper yet make more profit.)
- Protected by 60 internationally recognized patents for manufacturing and usage.
- Has no known drug interactions or side effects unlike Kava, Valerian, and St. John's Wort — often taken instead of L-theanine — which may have severe contraindications with alcohol, over-the-counter medications, and prescription drugs.
- Safer than Kava, which research indicates may be linked to hepatotoxicity in such cases as hepatitis, cirrhosis, and liver failure.
- Safer than Valerian, which can cause drowsiness and may also impair motor function.
- Pure, patented, pharmaceutical-grade L-theanine.
- Suntheanine is FDA GRAS certified (Generally Recognized as Safe).

Background Information:
L-theanine, a unique and naturally-occurring amino acid found almost solely in green tea plants, is both expensive and time-consuming to extract. Since just 1-2% of this ingredient is present in tea leaves, it’s impossible to yield 100% purity in the process.
In more than 45 different studies, Suntheanine — which is structurally identical to the L-theanine found in tea leaves — has been found to reduce stress and anxiety, promote relaxation, and improve learning and concentration*.
Suntheanine was also found to diminish normal symptoms associated with Premenstrual Syndrome (PMS). One study found that 200 mg of Suntheanine per day significantly reduced physical, mental, and social symptoms of PMS including insomnia, muscle stiffness, cramps, depression, anxiety, and irritability*.
Suntheanine can also counteract the negative side effects of caffeine and ephedrine. After injecting mice with Suntheanine, results showed that convulsions induced by high doses of caffeine were notably diminished. Suntheanine has also been found to reduce hypertension and limit sleep disturbances*.
L-Theanine by Suntheanine contains 100% Suntheanine. As the only pure form of L-theanine on the market with no known side effects or drug interactions, L-Theanine by Suntheanine gives you a safer alternative for reducing stress and feeling better*.
