WHITE PLAINS, N.Y.—ConsumerLab.com tested plant seed oil products containing omega-3 and omega-6 fatty acids and found that 14 out of the 16 products selected for testing contained what was stated on the labels. One supplement was found to completely lack the omega-6 fatty acid GLA (gamma-linolenic acid), indicating that it didn't contain a plant oil it promised. Another product mislabeled its amount of oleic acid, an omega-9 fatty acid. In addition to testing each product for omega-3 and -6 fatty acids, ConsumerLab.com tested for freshness and potential heavy metal contamination (lead, arsenic, and cadmium).
Test results and comparisons of the 16 products selected by ConsumerLab.com for testing, as well as for 10 supplements which passed the same testing through ConsumerLab.com's voluntary Quality Certification Program, are provided in a new report online.
The report includes information about the uses, dosage, and potential side-effects of the seed oil supplements, for personal care and pet care use.
