“ The pituitary gland produces endorphins, while the thyroid gland produces serotonin; production of the two chemicals is often correlated so that elevating endorphin levels can produce a natural rise in serotonin levels.
This is poor info, not everything on the internet is correct.
Anyone worried about
serotonin- 90% is made in your gut.
Thyroid hormone production is needed for your gut to work right. The thyroid itself does not make seritonin. So at best its indirectly related.
