Question: What cofactors are needed to synthesize and recycle BH4?
Short Answer: Zinc, magnesium, potassium, and niacin are the cofactors needed for the synthesis and recycling of BH4. Folate and methylation are not involved, though high-dose folate or folic acid could hypothetically hurt BH4 recycling since both are recycled by dihydrofolate reductase (DHFR).
