As a supplement

Roll Call does not check drug interactions or assess personal safety.

A naturally occurring mineral element, present in the body mainly as part of certain amino acids and in compounds like glutathione. As a standalone supplement ingredient it is typically elemental sulfur or a simple sulfur compound, distinct from related supplement forms like MSM.

Why it’s used

Taken by some for general skin, joint, or hair support, based on sulfur's role in body proteins.

What the evidence says

There is little to no clinical trial evidence examining elemental sulfur supplementation on its own for any specific outcome in humans. Its biological importance is well established as a component of amino acids and proteins made in the body from dietary protein, but that is a different question from whether taking extra elemental sulfur as a supplement does anything measurable.

This says what this database holds under these terms. It is not a finding that no research exists.

Context

Dietary sulfur needs are normally met through protein intake, and standalone elemental sulfur supplements have not been the subject of the kind of dose-ranging human studies that would establish an effective amount.
