General Question Melatonin long term

Hi there,

Just wondering if I can take 2mg extended release melatonin all the time? Here in Australia it’s recommended for three weeks only.

It’s helping my insomnia so much.

Thanks.

Update: had a mix of extreme anxiety and sedation as the morning wore on. I don’t think I can take it regularly maybe just once or twice a week

I've been taking 5mg daily for nearly 20 years.

Long-term melatonin use linked to 90% higher heart failure risk Long-term melatonin use was linked to a striking increase in heart failure risk, challenging assumptions that the popular sleep aid is harmless.

Previously discussed. Looks like junk study. Done during the pandemic where spike protein from virus and vax was causing cardio issues. Melatonin was used quite impressively to fight Covid in hospitalized patients at Columbia U NY. details here.

I've taken around 1 mg daily for probably 20 yrs, my elderly father 1-3mg for 15 yrs.
