Researchers at Sweden's Karolinska Institute and at the National Institutes of Health are finding a connection between tyrosine hydroxylase activity, thyroid hormone receptors, and depleted dopamine levels in the brain — particularly in the substantia nigra, a region associated with the movement difficulties characteristic of Parkinson's disease.11, 12,13
Calcitriol, the hormonally active form of vitamin D, accumulates in the adrenals, and this stimulates the production of the gene for tyrosine hydroxylase, which is involved in serotonin production.
