L-tryptophan is an essential Amino Acid , which means the human body cannot produce it and needs to obtain it through diet. Serotonin can help improve mood, reduce anxiety, and tryptophan also contributes to the production of melatonin. It participates in the production of antibodies and supports immune function. As an amino acid, it is essential for protein synthesis and is crucial for the growth, repair, and maintenance of body tissues, Ingredients For DNA Or DHA

L-tyrosine can help reduce the negative effects of stress by increasing the production of neurotransmitters such as dopamine and norepinephrine. It supports cognitive function and can enhance psychological clarity and focus. Some studies suggest that it may improve memory and reaction time, tyrosine can increase metabolic rate, aid in weight loss and management, and improve physical fitness, especially in endurance activities, as it can increase the production of adrenaline and norepinephrine, and L-tyrosine plays a role in immune system function. It participates in the production of thyroid hormones, which are crucial for metabolism. By producing dopamine and tyrosine, it can help regulate emotions
