Dr Bernard Jensen in his book on arthritis, rhemetism and osteoporosis died talk about the need for getting organic sodium that is natural in food while stopping sodium form salt.

He said a few of the best sources are whey and Celery juice so this does seem plausible to me

he has other suggestions and the book is pretty cheap on amazon

You might also try raw apple cider vinegar three times a day in water (braggs, edem, spectrum are common brands)see the book Arthritis by dr dc jarvis

May add raw honey if you like as this is helpful with it..since calcium can cause bone spurs if it is not going to bones right, these book would be of help
