Ubiquinone and exercise capacity in trained men

Editorial study summary

Study type

Double-blind, placebo-controlled human crossover trial.

Product relevance

Ingredient evidence for ubiquinone, the oxidized form of CoQ10. The trial did not test the DR.MORGAN formula.

Sample or population

11 younger and 8 older trained men.

Studied dose

120 mg/day of ubiquinone or placebo.

Duration

6 weeks of ubiquinone supplementation.

Finding

Serum ubiquinone increased. Maximal oxygen uptake did not improve, time to exhaustion was longer with placebo, and serum malondialdehyde did not change.

Limitations

The sample was small and limited to trained men. Blood exposure did not translate to better exercise performance.

Study quality

Controlled crossover with separate age groups and objective exercise testing. Editorial review was limited to the abstract. No formal risk-of-bias rating was assigned.

Funding and disclosures

Funding and conflicts were not verified from the abstract.

The studies discussed here examine ingredients or other formulations. They do not establish results for this DR.MORGAN finished product.
