The Active Ingredient Is: CoQ10 (Ubiquinol Form)

CoQ10, also known as ubiquinol in its reduced form, is a nutrient that functions as a key component of cellular energy production. This ubiquinol form is produced by natural fermentation and is recognised for improved bioavailability in some formulations.

This form is supplied as ubiquinol to support reliable absorption, with Klaire Labs offering it in a high-quality, clinic-grade preparation designed for consistent potency and traceable identity.

What CoQ10 Does?

CoQ10 plays a part in energy metabolism inside cells and helps support cardiovascular health and healthy ageing, in line with EFSA and NHS style guidance. The ubiquinol form is noted for its potential in keeping cellular energy and antioxidant protection as part of everyday bodily function.

Research suggests that ubiquinol supplementation can boost plasma CoQ10 levels and support energy production, especially in older adults, while keeping metabolic processes safe and normal.
