Welcome @frman, My vote is for door number 2. @sueinmn has some good information in her post earlier in the discussion here - https://connect.mayoclinic.org/comment/658326/

Do you mind sharing a little bit about your condition, symptoms and any treatments you've tried?

The concept of "salt" in joints is a hoax.
When salt is said to be bad for people with inflammatory conditions, it is consumption of too much salt that can increase inflammation in the body. The salt does not deposit in the sore joint. Anyone who promotes this theory is not grounded in scientific evidence.
I will repeat my former caution - this looks like another "miracle cure" for a condition the plagues us with aches and pains, but will not go away. The ingredients all appear to be safe, but the evidence that this is any better than Brand X is just plain lacking, and the price is high. There has been no independent testing and certification of the product, or if there was, it did not prove their claims, so it wasn't published.
Nope, not for me...
