LTO3 increases brain levels, the neurotransmitter of pleasure and reward- and serotonin, the primary inhibitory neurotransmitter, which are critically degraded in situations of stress and overwork. It thus reduces the chronic conditions of stress, anxiety, and depression without violence to the natural functioning of the brain, as opposed to synthetic antidepressants.

LTO3 readily crosses the blood-brain barrier and triggers tranquilizing effects on the brain. LTO3 protects the brain from neurotoxicity induced by glutamate, one of the leading causes of neurodegenerative diseases. LTO3 induces relaxation without causing drowsiness, which can be verified by the increased generation of alpha-waves in the brain. Studies show that it improves the brain's ability to concentrate. Unlike caffeine, LTO3 increases brain levels of GABA (gamma-aminobutyric acid), an inhibitory neurotransmitter that invites relaxation and promotes a sense of well-being. LTO3 significantly reduces mental, physical and social symptoms associated with premenstrual syndrome.


LTO3 helps in the following situations;








Quickly absorbed by the small intestine, LTO3 is transported directly to the brain. Although effective doses are between 50 and 200 mg of LTO3, it only takes 30-40 minutes to get to a gentle awakening of the state of mind and emotion, as well as vigilance. This effect lasts from 8 to 12 hours. LTO3 can be ideal for people who have difficulty sleeping and feel tired in the morning. Take one to two capsules one hour before bedtime.
