Melatonin supplements linked to side effects and hormonal changes

Melatonin, frequently marketed in online shops as a natural sleep aid, is being scrutinized for its potential side effects and impact on hormonal balance. While many users turn to the supplement to combat sleep issues, it can lead to adverse reactions such as headaches, decreased blood pressure, and lowered body temperature. Some users have reported feeling groggy or lethargic for several hours after consumption.

Beyond sleep disruption, there are concerns regarding how certain supplements, including melatonin, may interfere with hormonal axes. Specifically, melatonin is noted for its potential to influence the HPG axis, which could lead to a reduction in libido. Other supplements like St. John's Wort and saw palmetto are also mentioned in discussions regarding their impact on hormonal health and potential interactions with other medications.
