The body hydroxylates it to L-DOPA, decarboxylates that to dopamine, and from dopamine builds norepinephrine and then epinephrine — the chemistry of attention, drive, and the acute stress response. It is also the precursor to thyroid hormone and to melanin. Few amino acids carry so much downstream traffic.\u003c\/p\u003e\u003cp\u003eThe catch is that free tyrosine is not especially stable or soluble. N-acetyl-L-tyrosine is the amino acid with an acetyl group attached at the nitrogen, which improves its solubility and its stability in solution; the acetyl group is cleaved in the body, releasing tyrosine.\u003c\/p\u003e\u003cp\u003ePyridoxal-5-phosphate is the active coenzyme form of vitamin B6 — the form the liver would otherwise have to convert pyridoxine into. It is the required cofactor for aromatic L-amino acid decarboxylase, the enzyme that makes dopamine from L-DOPA. Supplying the substrate without the cofactor is half a formula, which is why both are here.\u003c\/p\u003e\u003cp\u003eUsed to support normal neurotransmitter synthesis and normal cognitive function under demand.\u003c\/p\u003e\u003cp\u003eHypoallergenic, no diluents, binders, or fillers.\u003c\/p\u003e\u003cp\u003eNALT 300 mg · P5P 10 mg · Available in 120 capsules\u003c\/p\u003e\u003cp\u003e\u003cem\u003eThese statements have not been evaluated by the Food and Drug Administration.
