ConsumerLab tests Coenzyme Q10

Just 1 of 39 coenzyme Q10 (CoQ10) (ubiquinol) supplements tested contained levels lower than listed on the label.

But large variations in dose and forms may confuse consumers, according to ConsumerLab in their latest report.

Among the 39 products, suggested daily doses ranged from 22 mg to 600 mg and some products were “solubilized” to deliver more than twice as much CoQ10 into the blood as simple capsules.

The 1 product that provided just 87% of its claimed ingredient indicated that it was made under the FDA Good Manufacturing Practices.

The bottom line?
CoQ10 has been used, recommended, or studied for many conditions. Here’s a summary from 2 websites that reviewed the literature.

The products tested are listed on the ConsumerLab website. You have to subscribe to their service in order to have access to the entire report.
