Is Suntheanine Bad For You?
Short answer
No, Suntheanine is not bad for the human body. This patented substance shares the same benefits with its base compound L-theanine (theanine), but at a higher price. This refined form is said to be far more effective. The additional substances that may be present in a Suntheanine tablet are inactive and benign, especially in the amounts that may be present.

Category 'F'
Category 'F' is for things that fail to bring anything beneficial to the table, and are very harmful to your health. We recommend completely avoiding anything in this category. Long-term side effects of 'F' items are usually very serious.

Long answer
Much like L-theanine, Suntheanine promotes alpha brain waves that are known to induce a state of mind that is both relaxed and alert at the same time. This new form of an age-old tea extract may be used as part of a supplemental vitamin regiment. However, users can expect some uncomfortable side effects when used in larger than recommended doses, and may include headaches and dizziness.
The active ingredient in Suntheanine is believed to release large quantities of dopamine, in turn helping the brain halt the onset of a cerebrovascular accident, or commonly referred to as, a stroke. However, there is no definitive proof to authenticate this theory. Suntheanine is not limited only to stroke prevention, but also positively impacts areas of the brain that are responsible for mood, focus, and nervousness. This L- theanine derivative is also attributed to immune wellness and the manufacturer claims that it will ease the adverse symptoms associated with pre-menstrual syndrome (PMS) in females.
Since the active ingredient in Suntheanine is L-theanine, it is important to point out that patients that are treated with sedative medicines should consult with their physicians before deciding to use this product. L-theanine is considered to be a relaxant supplement, and therefore may induce deeper sedation in individuals using sedatives and hypnotic drugs. Additionally, pregnant women should always consult their doctors prior to considering any supplement.
