Now L-Tyrosine 750 mg Capsules are pharmaceutical-grade supplements designed to support neurotransmitter production and healthy glandular function. This conditionally essential amino acid plays a crucial role in the synthesis of neurotransmitters like dopamine, adrenaline, and noradrenaline, which are vital for maintaining mental alertness, focus, and a positive mood, especially during stressful or demanding situations. Evidence suggests that supplementing with L-Tyrosine can help replenish these important neurotransmitters, enhancing cognitive function compared to a placebo. Additionally, L-Tyrosine is important for the normal functioning of the thyroid gland.
