WHAT IS IT?

Norival contains the amino acid N-Acetyl L-Tyrosine 300 mg, Vitamin B6 10 mg, and Biopterin 25 mcg per capsule. Other ingredients include cellulose, magnesium stearate, and silicon dioxide.
 

WHAT DOES IT DO?

L- Tyrosine is an amino acid which is the precursor (the substance from which it is made) for brain neurotransmitters such as L-Dopa, dopamine, norepinephrine , epinephrine (adrenalin,) and Phenylethylamine (PEA.)

Like the acetylated version of other amino acids such as cysteine and carnitine, this version is more easily absorbed and more bioavailable than regular L- Tyrosine. It can therefore be used at a lower dose. Biopterin further enhances its bioavailability.

CAUTIONS
