A small amount wont do any harm but they now say it aint good to drink a lot. They think it helps strip you of minerals same as it does your plants. If you get a remin cartridge fitted to the output of your RO filtration unit then it’s good for you and your plants (we should all be drinking water with some mineral content) That is the advice i got from a few sources when i looked into this last year.
It’ll all change again soon no doubt so do what works for you
