Lycopene Supplements Review
 


How Products Were Evaluated

How Products Were Selected:
Products were selected to represent those commonly available in the United States. 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. For each product, the sample was composed of one or more purchased samples from a lot having an expiration date (if labeled) later than the date of testing.

Testing Method:
Lycopene products were evaluated for total lycopene content defined as the sum of the cis and trans isomers determined using High Performance Liquid Chromatography (HPLC) methodology. Potential lead contamination was determined by ICP-MS analyses. All applicable products were also tested for their ability to disintegrate in solution. Disintegration time of non-capsule, non-chewable and non-time release formulations was analyzed utilizing USP (United States Pharmacopeia) 2040 recommendations entitled "Disintegration and Dissolution of Nutritional Supplements."

Products not having passing levels of key ingredients or contaminants were then re-tested in a second independent laboratory using similar methods and instrumentation. The identities of the products were not disclosed to the laboratories performing the testing.

Passing Score: *
To pass testing, a product must meet all of the following criteria:
  1. Contain a minimum of 100% and no more than 135% of label claim of total cis/trans lycopene or specific lycopene isomers.
  2. Meet recommended USP parameters for disintegration of products (excluding capsule, enteric coated, chewable and time-release products).
  3. Not exceed the State of California's Prop 65 limits for lead in supplements in a recommended daily serving: 0.5 mcg of lead per daily serving with an additional allowance of 1.0 mcg for supplements containing 1,000 mg/day or more of elemental calcium and 0.5 mcg for supplements containing specific other minerals**. For supplements not marketed for use by children, ConsumerLab.com provides an additional allowance of 0.5 mcg if containing 250 to 499 mg/day of elemental calcium or 1.0 mcg if containing 500 to 999 mg/day of elemental calcium and an allowance of 0.5 mcg for if containing one whole herb (not extract) ingredient or 1.0 mcg for two or more whole herb ingredients. If a maximum recommended daily serving is not defined, a daily serving size will be determined and applied by CL.
  4. Meet all FDA labeling requirements.

A "Pass" was based on meeting the above criteria in either the first or second round 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 present a safety risk or to provide misleading or inaccurate label information.

** Based on the State of California’s Prop 65 lead limit. California requires supplements exceeding this limit to display a warning label regarding lead.
