How Products were Selected:

Products tested represent those popular among members of ConsumerLab.com and commonly sold and/or available in the U.S. ConsumerLab.com purchased products on the open market through retail stores, on-line retailers and direct sales companies. Products were not accepted directly from manufacturers.

Testing Methods:

  1. Products were tested for their total calories, total fat, poly- and monounsaturated fat, saturated fat, trans fat, cholesterol, protein, amino acids, total carbohydrates, total sugars and sodium content using Association of Official Analytical Collaboration (AOAC) International methods.
  2. Analyses for lead, arsenic, cadmium, mercury and sodium were performed using Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS).
  3. Quantitative analysis of gluten in any product claiming to be gluten free by Enzyme Linked Immunosorbent Assay (ELISA).
Testing was performed by one or more independent contract laboratories. Any product that did not pass (below) a test was sent to another independent laboratory to repeat testing for the criterion on which it did not pass.

ConsumerLab.com may modify or use other appropriate test methods if necessary to test special product formulations.

The identities of the products were not disclosed to the laboratories performing the testing.

Passing Score:*

To be "Approved" by Consumerlab.com, a product must meet the following requirements:
  1. Specify the amount of all nutrients in the product as required by the FDA and be appropriately classified as a food or dietary supplement.
  2. Meet its label claims within a specified range for each nutritional component as indicated below:
    • Total Fat (within 1 gram or 15% above claimed amount or 2 grams or 30% under claimed amount, whichever is greater; or, if claiming or, if claiming zero total fats, no more than 1 g per serving);
    • Saturated Fat (within 0.5 gram/serving or 15% above claim, whichever is greater; or, if claiming zero saturated fats, no more than 1 g per serving);
    • Trans fat (no more than 0.5 gram per serving - FDA 2018);
    • Cholesterol (within 5 mg/serving or 15% above claim, whichever is greater; or, if claiming zero cholesterol, no more than 2 mg/serving);
    • Sodium (within 50 mg/serving or 15% above claim, whichever is greater; or, if claiming zero sodium, no more than 5 mg/serving);
    • Protein (within 1 gram/serving or 15% of claim, whichever is greater);
    • Total Carbohydrates (within 5 gram/serving or 15% of claim, whichever is greater; or, if claiming zero to 3g/serving of carbohydrates, within 1g of claim);
    • Total Sugars (no more than 1g claim over or 2g under claim or 15% above claim, whichever is greater; or, if claiming zero sugar, no more than 0.5 gram/serving);
    • Total Calories (within +/- 20% of claim).
  3. Heavy Metals: Products containing whole plant ingredients, rice bran, cocoa, or more than 250 mg of minerals per daily dose must not exceed the following specific limits for lead, arsenic, cadmium and mercury.
    Lead:
    • Products marketed for use by children under 12 years of age or by pregnant or nursing women may not exceed the State of California's Prop 65 limits for lead in dietary supplements of 0.5 mcg per recommended daily serving with an additional allowance of 0.8 mcg if the product contains more than 1,000 mg/day of calcium.
    • Products with a single serving weight of less than 5 grams that are not marketed for use by children under 12 years of age, may not exceed the State of California's Prop 65 limits for lead in dietary supplements of 0.5 mcg per recommended daily serving (above which a warning regarding reproductive harm, birth defects, or cancer risks is required in California) with an additional allowance of 0.4 mcg if containing 250-999 mg/day of any combination of elemental calcium, magnesium and potassium or 0.8 mcg if containing more than 1,000 mg/day of any combination of these minerals. An additional allowance of 0.5 mcg is provided if containing 250-999 mg/day of whole herb (not extract) or 1.0 mcg if containing 1000 mg/day or more of whole herb (not extract). However, total lead allowance must not exceed 2 mcg per daily serving.
    • Products with single serving weights of 5 grams or more that are not marketed for children under 12 years of age may not exceed 2.5 mcg per serving nor 4.0 mcg per daily serving.
    Arsenic:
    • Contain less than 10 micrograms of total arsenic per daily serving (based on Canada’s limit per daily serving of a natural health product, and U.S. EPA and state of New Jersey limit in 1 liter of water). Products found to exceed this amount were tested for inorganic arsenic and must not contain more than 2.1 micrograms of inorganic arsenic per daily serving (Canada's additional limit in natural health products).
    Cadmium:
    • If marketed for use by children under 12 years of age, may not exceed 3.0 micrograms of cadmium per recommended daily serving (based on Canada's limit for a child weighing 75lbs). If not marketed for use by children under 12 years of age, may not exceed 4.1 micrograms of cadmium per recommended daily serving (above which California's Prop 65 law requires a "reproductive harm" warning due to developmental toxicity and male reproductive harm).
    Mercury:
    • May not exceed 2 micrograms of inorganic mercury per daily serving (based on EPA limit for mercury in 1 liter of water).
  4. Gluten: Products labeled as "Gluten-free" must contain less than 20 ppm of gluten (FDA), except that products with serving sizes greater than five grams or five mL must contain less than 10 ppm of gluten.
  5. Meet all FDA labeling requirements.
A "Pass" was based on meeting the above criteria in either the first or second rounds of testing.

* Passing scores allow for specific margins of technical error associated with each analysis. ConsumerLab.com reserves the right to disqualify a product at any time from passing if it considers such product to display unacceptable variation in quality, present a safety risk or to provide misleading or inaccurate information in its labeling.
