Tetrahydrobiopterin (BH4)

Tetrahydrobiopterin (BH4) is a naturally occurring molecule in the body that acts as a critical helper in producing certain amino acids and neurotransmitters, such as serotonin, dopamine, and norepinephrine. It also plays a key role in the proper functioning of enzymes involved in converting the amino acid phenylalanine into tyrosine. Without enough BH4, these processes can be disrupted, leading to neurological issues and metabolic problems. BH4 is essential for maintaining normal brain chemistry and amino acid balance, and it’s sometimes used as a supplement to treat specific metabolic disorders related to enzyme deficiencies.
