Father in law started doing it a few months back to help him sleep. Loves it. But don’t go cheap only get the good stuff. I think he puts a couple drops under his tongue before bed.
Try it but make sure it’s certified by a third party…you’ll pay more but at least it’s somewhat tested and reviewed. Anything else could be cat urine for all you know.
I work in the medical field and involved in research and studies such as SIREN…and I’d have no issues using this stuff.
My 40ish yr old buddy who is a granite counter installer takes a squirt of it morning and night. He says it has helped with all sorts of pains, sleep, etc. He buys “reputable” stuff that is about $100/bottle and I can’t remember how long he said that lasts.
I think at this point anecdotal evidence is mostly what you will get.
