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 significant contraindications with alcohol, over-the-counter medications, and prescription drugs.)
- Safer than Kava, which research indicates may be linked to hepatotoxicity (harmful to the liver).
- 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 support a healthy response to stress, promote relaxation, and enhance learning and concentration.*
Suntheanine was also found to soothe normal symptoms associated with Premenstrual Syndrome (PMS). One study found that 200 mg of Suntheanine per day significantly eased physical, mental, and social effects of PMS including insomnia, muscle stiffness, cramps, depression, anxiety, and irritability.*
Suntheanine can ease the effects of occasional caffeine consumption. Suntheanine has also been found to support healthy blood pressure levels and support healthy sleep cycles.*
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 promoting a healthy mood so you can start feeling your best.*
