The Claim

In healthy older adults aged 65–75, daily supplementation with 100 mg of CoQ10 combined with eight weeks of high-intensity interval training (three sessions per week) results in significantly greater improvements in insulin sensitivity and lipid profile than high-intensity interval training alone, as measured by larger reductions in fasting insulin, HOMA-IR, total cholesterol, triglycerides, LDL cholesterol, and vLDL.

Cause and effect
1 study reviewed
In plain English

In healthy adults aged 65 to 75, taking 100 mg of CoQ10 daily along with eight weeks of high-intensity interval training three times per week leads to greater improvements in insulin sensitivity and blood lipid levels than high-intensity interval training alone.

See the scientific wording

In healthy older adults aged 65–75, daily supplementation with 100 mg of CoQ10 alongside eight weeks of high-intensity interval training (three sessions per week) leads to significantly greater improvements in insulin sensitivity and lipid profile compared to high-intensity interval training alone, as evidenced by larger reductions in fasting insulin, HOMA-IR, total cholesterol, triglycerides, LDL cholesterol, and vLDL.

Why this might work

CoQ10 helps mitochondria produce energy more efficiently and reduces harmful molecules that interfere with insulin signaling and fat processing. This lets muscles take up more sugar and the liver handle fats better, so blood sugar and cholesterol drop more after exercise.

  1. Study: Impact of CoQ10 supplementation on metabolic adaptations to HIIT in older adults: focus on glycemic control, insulin resistance, lipid profile, and liver enzyme

    For older adults doing intense interval workouts, taking a daily CoQ10 supplement made their blood sugar and cholesterol levels improve even more than just working out alone.
