I have RA and I have been taking CBD oil for a few months now, and I definitely see a difference. I started with tincture, but the drops are hard to measure, so I went with capsules. I started with one 15mg capsule, but after a couple of weeks I increased it to 2 - 15mg capsules before bed.
Normally joint pain makes it very hard to fall asleep, and stay asleep but now I sleep like a dream most nights and I wake up much more relaxed and I think the inflammation in my joints is less too.
I do take prednisone daily for the last 4 yrs, but so far I have not had to increase my dosage this year, amazing.
It's much cheaper than the RA meds the Dr wants me to take, the meds are around $2400 to $4800 a month and have horrible side effects but CBD is only about $75 a month and no side effects at all for me at all.
As long as it keeps working, I'll keep taking it. I buy mine online and they ship it to me, but now that I know what strength and what type I use, I'm going to check out some local shops around here that sell it and see if the price is better.
