Ingredients

Supplement ingredients in a single table. Select a highlighted name to open the page about that ingredient.

  • The table is ordered by group, then by category (a thick line marks where each category starts), then by role. Within a role, ingredients are ordered by the number of products that state them in the Supplement Facts panel.
  • “Group” is the type we assign from the ingredient classification; carbohydrates, excipients and blends go under “Other”. “Category” is the nutrient or other category.
  • “Role” has three values. “Nutrient” is the name of the nutrient with no form stated (in categories that group related nutrients, such as omega-3 fatty acids, each member). “Form” is a salt, ester, coenzyme form and so on that counts directly toward the amount of the nutrient. “Related” is a compound of the same family that is counted differently or not counted. Materials that contain the nutrient (fish liver oil, algae, plants and so on), whose label weight is the weight of the material rather than the nutrient, are not listed. Branded ingredients such as FloraGLO get the same role as the ingredient they contain.
  • “Type” is the chemical class, such as the kind of salt or ester. Where the category is itself a raw material, such as a plant, mushroom, microbe or enzyme, the role is “—” and “Type” shows the kind of material instead (whole or extract, the group of bacteria, what the enzyme breaks down).
  • Groups, categories and ingredient classes are assigned automatically from ingredient names. Roles and types are assigned by us from ingredient names and classes. Check the product label for how a specific product treats an ingredient.
  • Key nutrients are ingredients often used as the main ingredients of supplements worldwide, selected by us: vitamins and minerals, fatty acids such as omega-3, amino acids such as BCAAs, CoQ10, carotenoids such as lutein, polyphenols such as curcumin, herbs such as ashwagandha, probiotics, enzymes, mushrooms and more. Probiotics, enzymes and mushrooms are combined into one row each. Everything else is on the “All categories” page.
  • Rows are mainly ingredients identified by a UNII (unique ingredient identifier). Under the key nutrients we also list names without a UNII when at least 100 products use them as a main ingredient.
  • Spellings that differ only in punctuation, spacing or plural form (such as Coenzyme Q-10 and Coenzyme Q10) share one row. Abbreviations and other names share a row only when we have confirmed them as the same substance (DHA and docosahexaenoic acid, CoQ10 and coenzyme Q10, and so on); others stay as separate rows.
  • The product list filtered by an ingredient counts every spelling under the same identifier (Cobalamin and Vitamin B12, for example), as well as products labeled with a merged abbreviation or other name. A row with an identifier is named after the spelling used on the most products under it (except where we have named the ingredient ourselves).
  • For some categories, mainly vitamins and minerals, the description gives only what sets the ingredient apart (a dash means nothing specific is noted). Statements about absorption come from US NIH fact sheets (see Sources below) and do not describe the effects of any product. Elsewhere, descriptions not written individually are generated from the ingredient classification.
