L-Tyrosine
Flavor: characteristic
L-tyrosine is classified as a non-essential amino acid. This means the body can synthesize sufficient amounts to meet daily needs. An existing theory indicates that L-tyrosine is a semi-essential aminoŚunder certain situations the body cannot meet demands and additional L-tyrosine must be acquired through diet or supplementation.
