L-Tyrosine Lamberts is presented as an amino acid in free form for maximum absorption. Amino acids are used by the body to build proteins. Proteins are essential for the formation of cells, being also linked to the biochemical structure of hormones, enzymes, neurotransmitters and antibodies. Amino acids are classified as essential or nonessential. Essential amino acids cannot be synthesized in the body and must be obtained through the diet, while non-essential amino acids, even though they are extremely important for health, can be synthesized in the body and, therefore, are not classified as “essential” . Lamberts amino acids are presented in "free form", that is, they are ready to be absorbed and used by the body, (they do not need to be digested). Tyrosine is a non-essential amino acid, because it can be produced by the body from phenylalanine, but it is also obtained from protein-rich foods like cheese, chicken, fish, and soy. It is recommended to take 1 to 4 capsules a day with water or fruit juice. Food supplements should not be used as a substitute for a balanced and varied diet and a healthy lifestyle. Do not exceed the recommended daily dose. Keep out of reach of young children. L-tyrosine should not be used with MAO inhibitors (a type of antidepressant drug). Store in a cool, dry place, protected from light and out of the reach of young children.
