The Claim

In healthy older adults aged 65–75, high-intensity interval training combined with CoQ10 supplementation results in greater reductions in low-density lipoprotein cholesterol and triglycerides compared to high-intensity interval training alone.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

Among healthy adults aged 65 to 75, combining high-intensity interval training with CoQ10 supplements leads to larger decreases in LDL cholesterol and triglycerides than high-intensity interval training by itself.

See the scientific wording

In healthy older adults aged 65–75, high-intensity interval training combined with CoQ10 supplementation leads to greater reductions in low-density lipoprotein cholesterol and triglycerides than high-intensity interval training alone.

Why this might work

During high-intensity interval training, the body burns fat for energy, but in older adults, this process is less efficient. CoQ10 helps mitochondria work better by reducing harmful molecules and improving how they break down fat. This leads to less fat being made in the liver and more fat being cleared from the blood, lowering bad cholesterol and triglycerides.

    When older adults do intense exercise, adding a supplement called CoQ10 helps lower their bad cholesterol and triglycerides even more than exercise alone. The study showed this clearly.
