Ubiquinol is the reduced, active antioxidant form of coenzyme Q10 (CoQ10), a compound naturally present in the body and crucial for energy production in cells. It plays a key role in the electron transport chain within mitochondria, which is essential for ATP synthesis – the energy currency of the body. Compared to its oxidized form, ubiquinone, ubiquinol is more bioavailable and readily utilized by the body.
In the context of physical activity, ubiquinol supports mitochondrial function and helps reduce oxidative stress caused by intense training. Its antioxidant properties are especially relevant for protecting muscle cells and cardiovascular tissues from free radical damage.
Ubiquinol becomes increasingly important with age, as the body’s ability to convert ubiquinone to ubiquinol diminishes. Supplementation can help maintain optimal cellular energy and recovery capacity, particularly in active individuals.
Synonyms:
Reduced CoQ10, Active CoQ10
Benefits:
- Supports mitochondrial energy production
- Enhances cardiovascular health and endurance
- Protects cells from oxidative stress
- May reduce exercise-induced fatigue
- Helps maintain performance in aging athletes
Sources:
- Naturally found in organ meats (e.g., heart, liver), oily fish, and whole grains
- Produced through fermentation in supplement form
Observations:
Often used in softgel capsules or combined with other antioxidants in performance or anti-aging supplements. Typical doses range from 50 to 200 mg per day. Excessive intake may cause mild gastrointestinal upset in some individuals. May interact with blood-thinning medications.
