At least not so natural that just 'anybody' can put it in a bottle.
Could they have chosen to bring it to market as a supplement?
Raising money to do clinical trials doesn't indicate the path to market.
Unless we expect that every protein combination exists somewhere in nature, this pretty much by definition isn’t naturally occurring.
But its " Gila Monster’s venom".
So natural, but you aren't going to just go out and eat it like resveratrol from wine.
At this point, 'natural', just means made from atoms, yes atoms are naturally occurring.
That pretty much covers everything in the universe. I've always thought it was natural vs synthesized.
When really, just being 'natural', doesn't mean anything really. There are poisons that are 'natural'.
Like resveratrol. Yes, it is natural and its in wine. But you need to drink many gallons a day to get enough to do anything. But people see 'Natural' and wine, and think it is a license to drink a lot.
