Does melatonin effect ovulation? is it bad if you take it once every couple months because i read online it effects ovulation. is it safe?

Yes: Melatonin is safe, but it does impair fertility, and you should not take it if you are trying to conceive. Otherwise it should be fine.

See answer: Melatonin can effect hormone levels in women, including changes in the levels of progesterone, estradiol, luteinizing hormone and thyroid levels, which can affect both ovulation and menstruation and cause problems with conceiving or maintaining a pregnancy. Bcps increase how much melatonin the body makes. Taking melatonin along with birth control pills might cause too much melatonin in the body.
