If your arthritis pain is due to inflammation, which I think the majority of arthritis pain is, then as Piedmont mentions, look into "anti-inflammatory diet". BTW, the reason Turmeric is mentioned, is because it's a known anti-inflammatory. When I learned that, I started using the spice liberally in my cooking...and I like the flavor/color it adds to some food, especially chicken.
Lastly, I will add this, CBD oil is a known anti-inflammatory. I use it regularly for the arthritis pain in my Knees and I find it works as good or better than OTC pain meds...PLUS I don't like to take OTC pain meds regularly. I realize to some this product is controversial and I will not argue about it, I will only state my personal experience...and that it is legal in all 50 states thanks to the US Farm Bill, that was passed in 2018.
