Natural occurring levels of dimethyl sulfoxide in selected fruits, vegetables, grains, and beverages

Pearson TW, Dawson HJ, Lackey HB · Journal of Agricultural and Food Chemistry

The canonical survey of where MSM and its precursor occur naturally in the food supply — and its scope is the answer to a common claim: fruits, vegetables, grains and beverages. No meat, bone, connective tissue or stock was examined, and no analytical study since has measured MSM in any of them.

Population

Selected fruits, vegetables, grains and beverages (analytical survey, no subjects)

Intervention

Measurement of naturally occurring dimethyl sulfoxide and dimethyl sulfone levels in foods

Limitations

No abstract is indexed in PubMed, so the individual per-food concentrations circulating in secondary sources could not be verified here from the primary text; cite those figures as secondary. Establishes scope, not joint relevance.
