Sulfur interferes with the storage of
copper, an essential trace element,
however with copper levels being on the high side with many people, this
is generally a positive effect. It is interesting that patients with normal
or below-normal copper levels rarely exhibit deficient sulfur levels. In fact,
the benefits of sulfur-containing supplements (Glucosamine Sulfate, MSM)
on some forms of arthritis are not just a result of their positive effect on
cartilage regeneration, but are largely based on lowering elevated copper
levels which promote joint degeneration, particularly - or more so - on the
right side of the body.
