Melatonin can induce sleep and reduce cortisone stress but this was done in Zebra Fish…

Lunkes LC, Paiva IM, Egger RC, Braga WF, Alvarez-Leite JI, da Cunha Barreto-Vianna AR, Murgas LDS.
Melatonin administration attenuates acute stress by inducing sleep state in zebrafish (Danio rerio).
Comp Biochem Physiol C Toxicol Pharmacol. 2021 Apr 7;246:109044.

“Melatonin was able to modulate acute stress effects on zebrafish by inhibiting cortisol increasing levels, reducing locomotor parameters, inducing a sleep state, reducing lipid peroxidation and stimulating antioxidant enzymatic activity.”

Comment –

Doesn’t help sleep efficacy that much (2-7%)

But gets you to sleep a little faster(2-20 min)

Helps cancer little bit:

Melatonin has been shown to help irritable bowel syndrome:

Melatonin for the treatment of irritable bowel syndrome.

I take melatonin 15 mg hs for its anti-cancer effects and it does help sleep and irritable bowel some as well…
