L-Tyrosine by Doctor's Best
L-Tyrosine is a semi-essential amino acid with several important functions throughout the body. It is a building block for the formation of signaling substances in the brain and nervous system, such as the neurotransmitters adrenaline, norepinephrine and dopamine, and for the formation of Coenzyme Q10.
Essential in some situations
L-tyrosine is synthesized in the body from the amino acid phenylalanine, but supplementation with L-tyrosine may be helpful in some cases. The non-essential amino acid L-tyrosine under certain conditions becomes semi-, or conditionally, essential.
- Semi-essential organic amino acid
- Precursor of bioactive substances in the body

- Does not contain gluten and GMO-free
Tyrosine comes in an L shape and a D shape. Our body only recognizes the natural L, or left-turning, shape. The mirrored D-shape is the synthetic shape that is not found in living material. Doctor's Best L-Tyrosine contains only the natural L-form and therefore has a very high bioavailability.
Amino Acids Competition
The larger amino acids such as L-tyrosine, L-tryptophan, phenylalanine, methionine and the BCAA's leucine, isoleucine and valine all use the same so-called enzyme transport system for efficient absorption. In order to obtain maximum benefit from L-tyrosine, always separate Doctor's Best L-tyrosine from other amino acids or proteins. Carbohydrates can be taken together with L-tyrosine.
