Douglas Laboratories L-Theanine is an amino acid which has been demonstrated to induce relaxation, lower stress and reduce anxiety levels without daytime grogginess. In addition to relaxation, research on L-theanine suggests that it can have significant benefits for cardiovascular, immune and neurological health.
As it is digested in your small intestine, L-theanine stimulates your brain's production of alpha waves, which make you feel relaxed but alert and not drowsy. L-theanine also helps you stay relaxed by stimulating your body to produce other calming amino acids, such as dopamine, GABA, and tryptophan.
You may benefit from L-Theanine supplementation if:
- You often feel anxious for no reason
- You sometimes feel “free-floating” anxiety
- You frequently feel “edgy,” and it’s difficult to relax
- Falling asleep is sometimes difficult
- It’s hard to turn your mind off when you want to relax
- You occasionally experience feelings of panic for no reason
L-Theanine has a significant effect on the release or reduction of neurotransmitters like dopamine and serotonin, resulting in improved memory and learning ability. L-theanine may also influence emotions due to its effects on the increased release of dopamine. L-theanine reduces brain serotonin concentration by either curtailing serotonin synthesis or increasing degradation in the brain.
Warning: If you are pregnant or breastfeeding, or if you are taking any prescription medication, consult a physician prior to use. Excessive consumption may impair ability to drive or operate heavy machinery. Not recommended for consumption with alcoholic beverages.
Suggested Use: Adults take 1 capsule daily or as directed by physician. L-theanine is most effective in the range of 50-200 mg, with the effect being felt within 30 minutes and lasting for 8-10 hours.
