L-Tyrosine is a non-essential amino acid that comes from the amino acid phenylalanine. It is converted into dopamine and norepinephrine and found in nuts, fish, and poultry. Supplementation with both tyrosine and phenylalanine leads to alertness and mental arousal. It may also have a positive effect on your mood.
Tyrosine deficiency is thought to be present in those who are diagnosed with ADD/ADHD and can lead to depression, low blood pressure, and Restless Leg Syndrome. Tyrosine is also beneficial as a supplement to those with Parkinson’s Disease.
Please consult your doctor before taking any supplement.
