Form

And may I replace 'a natural form' with 'the natural form of'?

It means it's a natural configuration in which sulfur is found. You may not use "the" because there are many naturally-occurring sulfur compounds, not just MSM.

So, a natural form of?

Or may be 'An organic sulfur in the natural form'?

I don't really know what you're asking anymore.

Sulfur is an element, and found in minerals and in its pure elemental form (natural and inorganic).
Small amounts are in our cells as part of

AlpheccaStarsOrganic sources of sulfur are preferred because they are digestible.

I'll stick with onions, garlic, milk, and eggs and not the solvent MSM if you don't mind, even if it is organic!
