Since we are recommending alternatives to Miracle-Mineral-Supplement
not that Miracle-Mineral-Supplement wouldn't help but it may be wise to also try iodine. Take a look at the Iodine forum for more info

Iodine deficiency may be a major contributor to the widespread Arthritis problems in the US. A home remedy for Arthritis is consumption of two drops of Lugol�s solution each day. Two drops of Lugol�s solution contain thesame amount of Iodine as one Iodoral tablet. Lugol�s solution is a water solution of 10 per cent potassium Iodide and 5 per cent iodine.
