N-Acetyl-L-tyrosine, also known as NALT, is a modified form of the non-essential amino acid L-Tyrosine, or just Tyrosine. The addition of acetic acid makes the Tyrosine more bioavailable to the body. This means that it is more easily absorbed by the body. N-Acetyl-L-tyrosine is believed to be approximately 20 times more water soluble than standard a L-Tyrosine supplement.
L-Tyrosine is synthesized by the body naturally in the creation of proteins which is why it is considered a non-essential amino acid. While we don't require it through diet, taking additional Tyrosine in the form of NALT may offer an array of health benefits.
