A brand’s own lab report
California Gold Nutrition posts a lab report for its CoQ10 100 mg on iHerb. It is for lot B23016, dated April 10, 2023, and was run by Health Level One. It found 110 mg of CoQ10 a softgel (label: 100 mg) and no E. coli, Salmonella or Staph aureus. Lead was 0.083 mcg a softgel. A report like this covers one lot, not every bottle.
How to check your own bottle
- Look for the USP Verified mark or the NSF mark on the bottle.
- Search NSF’s list or USP’s list for the exact product name and strength. Nature Made has several CoQ10 strengths, and only some are listed.
- Read the Supplement Facts for CoQ10 in mg per serving, and the serving size. Some lists count 2 or 3 softgels as one serving, so match the serving size on your label to the one on the list.
- Choose the form you want. See ubiquinol vs ubiquinone and how much to take in the dosage guide.
Questions
Which CoQ10 supplements are third-party tested?
Nature Made CoQ10 200 mg, Kirkland Signature CoQ10 300 mg, Momentous Ubiquinol CoQ10 100 mg, Thorne CoQ10 100 mg, Thorne Ubiquinol 100 mg and Nordic Naturals CoQ10 Ubiquinol Sport 100 mg are each on a public list: USP Verified, NSF/ANSI 173 or NSF Certified for Sport. The lists check the label amount and set limits for contaminants. They do not print a result for each bottle.
Is Nature Made CoQ10 USP Verified?
Yes. USP lists Nature Made CoQ10 in 100 mg, 200 mg and 400 mg softgels and a 100 mg softgel with black pepper extract. The one we link is the 200 mg softgel, 80 count. USP’s list shows the product name, not the pack size. USP list read September 22, 2026.
Is Doctor’s Best CoQ10 third-party tested?
Doctor’s Best says its 200 mg capsule with BioPerine is USP Verified. We did not find it on USP’s list. The 100 mg softgel has no testing claim on its label. ConsumerLab bought and tested Doctor’s Best High Absorption CoQ10 With BioPerine for its 2024 review.
Is California Gold Nutrition CoQ10 third-party tested?
California Gold Nutrition posts a lab report for one lot of its CoQ10 100 mg (lot B23016, April 10, 2023), but the product is not on a USP or NSF list.
Which is better tested, ubiquinol or ubiquinone?
Both forms are on the lists. Thorne CoQ10 and Nature Made are ubiquinone; Thorne Ubiquinol, Momentous and Nordic Naturals are ubiquinol. A listing says nothing about which form absorbs better. See ubiquinol vs ubiquinone.
