Rating (out of 5): 4

Biopterin, specifically in its active form tetrahydrobiopterin (BH4), plays a crucial role in the dopamine system. BH4 is an essential cofactor for the enzyme tyrosine hydroxylase, which catalyzes the rate-limiting step in dopamine synthesis from the amino acid tyrosine. Deficiencies in BH4 are well-documented to result in impaired dopamine production, leading to neurotransmitter disorders such as some forms of hyperphenylalaninemia and dopa-responsive dystonia. Clinical use of BH4 (rather than biopterin itself, which is the oxidized, inactive form) has shown benefit in patients with certain genetic disorders affecting dopamine synthesis. Several studies and reviews have established the biochemical necessity of BH4 in the biosynthesis of dopamine, serotonin, and nitric oxide. However, evidence supporting the use of supplemental biopterin (as opposed to pharmacological or prescription BH4) in healthy individuals or for general support of dopamine function is limited. The use is scientifically justified in the context of specific enzymatic deficiencies, but general supplementation for dopamine support in healthy people is not broadly validated. Thus, the evidence is strong for clinical deficiencies but less so for routine supplementation.
