HOW PRODUCTS WERE EVALUATED:
How Products Were Selected:
Products tested represent those commonly sold and/or available nationally in the U.S. and Canada. ConsumerLab.com purchased products on the open market through retail stores, on-line retailers, and direct sales or multi-level marketing companies. Products were not accepted directly from manufacturers.
Cinnamon supplements and spices were tested in one or more independent laboratories for the following:
- Quantification of coumarin by High Performance Liquid Chromatography (HPLC).
- Quantification of flavanols and procyanidins (PACs) as a predefined molecular degree of polymerization (DP) of 1-7 by high performance liquid chromatography (HPLC) methodology .(applies only to supplements).
- Salmonella contamination; using the FDA's Bacteriological Analytical Manual (BAM) and AOAC methodologies (does not apply to extracts).
- Filth in spices as per AOAC method 968.38, Light filth testing in ground cinnamon (applies only to spices).
- Disintegration of non-chewable, non-capsule and non-time-release formulations utilizing USP (United States Pharmacopeia) <2040> recommendations entitled "Disintegration and Dissolution of Nutritional Supplements."
Any product not passing any initial testing criteria was sent to a second independent laboratory for repeat analysis using similar methodologies.
Identities of products were not disclosed to laboratories performing the testing.
To pass, a product must:
A "Pass" was based on meeting the above criteria in either the first or second rounds of testing.
- Not exceed the following limits for elemental lead: **
- Products with single serving weights of 5 grams or more which are not marketed for children may not exceed 2.5 mcg per serving or 4.0 mcg per daily serving.
- Products with a single serving weights of less than 5 grams which are not marketed for use by children, 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 0.4 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 will not exceed 2 mcg.
- Products marketed for use by children 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.
- Contain less than 10 micrograms of total arsenic and no more than 5 micrograms of inorganic arsenic per daily serving (EPA limit - based on 1 liter of water).
- Cadmium: If marketed for use by children, may not exceed 3.0 micrograms of cadmium per recommended daily serving (based on Canada's limit for a child weighing 75 lbs). If not marketed for use by children, may not exceed 4.1 micrograms of cadmium per recommended daily serving (based on the State of California's Prop 65 limit).
- Negative for salmonella, USP <2022> (All cinnamon products and spices).
- If applicable to the product, it must meet recommended USP <2040> parameters of disintegration for dietary supplements (excluding capsule, enteric coated, chewable and time-release products).
- Be in compliance with FDA labeling requirements.
- Ground spices must contain less than 400 insect fragments and less than 11 rodent hairs per 50 grams FDA Defect Level Handbook 2014.
* 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 its testing if it considers such product to present a safety risk or to provide misleading or inaccurate information in its labeling.
** If available for sale in California, a product that exceeds the State of California's Prop 65 lead limit requires a warning label. However, with or without this warning label, a product cannot pass ConsumerLab.com testing if it exceeds the levels described in this paragraph.
1 Passing score for elemental lead and arsenic in cinnamon spices based on a daily serving of 1 gram, and cadmium on a per gram basis. Levels of filth found in spices are shown in report. Pass/fail criterion based on U.S. government DAL (defect action levels) for filth specifically for ground cinnamon spice.
