Methylsynephrine in Dietary Supplements

Methylsynephrine is a substance that does not meet the statutory definition of a dietary ingredient. The Federal Food, Drug, and Cosmetic Act defines a dietary ingredient as a vitamin; mineral; herb or other botanical; amino acid; dietary substance for use by man to supplement the diet by increasing the total dietary intake; or a concentrate, metabolite, constituent, extract, or combination of the preceding substances. Methylsynephrine does not fit under any of these categories, rendering misbranded any dietary supplement products that declare methylsynephrine as a dietary ingredient.

Methylsynephrine is also known as:

  • oxilofrine
  • p-hydroxyephedrine
