I have used it and it was working for awhile but now it is starting to cause indigestion. You need to try different brands. The one that caused the indigestion one "Color spot"
I am researching other brands now.

I use CBD for my arthritis and restless leg. Some are oilier than others, meaning they have fish oil or others added. Be sure that the ingredients are compatible with your system.

This is the brand I've been using: https://pluscbdoil.com/ (the 15mg softgels seem to have really helped)

Yes, and my guts have actually been feeling much better! I'm typically super sensitive to anything with dairy or grains, and so have to almost completely stay off both (but can usually get away with doing dairy once a week if I take Lactase enzymes) but after taking CBD once or twice daily for the majority of the last month, things have been noticeably better!!! Just overall healthwise too. But I've been able to do dairy/grains more and have not had any flareups. Which is pretty exciting!

They can, if not reputable. If it sounds too cheap to be true it probably is. Tried some from amazon, did very little. Some from a Colorado company and its great for my RA. I hope it helps you.
