SR CoQ10 refers to a sustained-release form of CoQ10, designed to optimize absorption and efficacy. Traditional CoQ10 supplements can result in high peaks of the compound in the bloodstream followed by rapid drops, which may lead to inconsistent energy levels and reduced effectiveness. In contrast, the sustained-release formulation allows for a gradual release of CoQ10 over an extended period. This provides a more stable supply of this essential nutrient to the body's cells, enhancing its potential benefits.
