Why would they not just take supplemental melatonin? Body doesn’t know the difference.
Sorry, I had to excerpt the article for FR. At the end, the article does go on to say that melatonin could be prescribed as a supplement.
Sounds like the next thing to investigate. Just because we think the body doesn't know the difference doesn't make it so. It would have to be investigated and verified. In the meantime, I don't see any harm in women battling breast cancer trying this out.
