A clear guide to what CoQ10 is, why levels fall with age, and how to optimise absorption for healthy ageing. Could one molecule help your cells make more energy while defending them from oxidative stress?
If your CoQ10 naturally declines with age, what can you do to restore it for better metabolic and brain performance?
TL;DR
Coenzyme Q10 (CoQ10) sits at the heart of mitochondrial ATP production and acts as a lipid-soluble antioxidant in cell membranes. Levels fall with age and in many chronic conditions. Optimising CoQ10—through diet and especially well-absorbed supplements (e.g., liposomal CoQ10)—may support energy, cardiovascular health, cognition, exercise performance, and skin vitality. This article explains what CoQ10 does, where to get it, and why delivery method matters for healthy ageing and longevity.
Science Snapshot
- Core role: CoQ10 (ubiquinone/ubiquinol) shuttles electrons between Complex I/II and Complex III of the electron transport chain and quenches lipid peroxyl radicals in membranes.
- Ageing link: Tissue CoQ10 levels fall with age; mitochondrial dysfunction and oxidative stress are hallmarks of ageing that CoQ10 directly influences.
- Systems impact: Signals for cardiovascular markers, exercise capacity, glycaemic control, migraine frequency, skin appearance, and statin-associated muscle symptoms.
- Formulation matters: Conventional oral CoQ10 has modest absorption; advanced delivery (e.g., liposomal) aims to raise plasma/tissue availability.
What Is CoQ10?
Coenzyme Q10 belongs to the coenzyme Q family (ubiquinones) and is abundant in human cells. It is stored in the mitochondria and concentrates in energy-demanding tissues such as the heart, liver, brain, muscles, and kidneys. As a lipid-soluble molecule, CoQ10 embeds in membranes where it participates in electron transfer and antioxidant defense.
How CoQ10 Works: Glycolysis, ETC, and ATP
Nutrient metabolism begins with glycolysis in the cytosol, yielding pyruvate and reducing equivalents (NADH). Pyruvate enters mitochondria, fueling the electron transport chain (ETC). Within the ETC, CoQ10 accepts electrons from Complex I (NADH dehydrogenase) and Complex II (succinate dehydrogenase) and delivers them to Complex III. This electron flow powers proton pumping, establishing a gradient that drives ATP synthase to generate ATP—the cell’s energy currency.
Without adequate CoQ10, electron transfer becomes less efficient, ATP output drops, and oxidative stress may rise—effects that can be felt as fatigue, reduced exercise tolerance, and slower recovery.
CoQ10 and Anti-Ageing: Why Decline Matters
CoQ10 supports two themes central to longevity and healthy ageing: mitochondrial efficiency (energy production) and antioxidant protection (defending membranes, lipids, and DNA from oxidative damage). Multiple observational reports show that CoQ10 concentrations decline with age and are often lower in chronic conditions. Repleting CoQ10 may help maintain energy metabolism and reduce oxidative burden—two levers widely targeted in biohacking for longevity.
Evidence-Informed Benefits of CoQ10
| Area | Rationale | What to Watch For |
|---|---|---|
| Heart health | Myocardial tissue has high ATP demand; CoQ10 supports mitochondrial output and may aid symptoms in heart failure settings. | Use under medical guidance if on cardiac meds. |
| Exercise performance | Improves electron transport efficiency; antioxidant action may reduce exercise-induced oxidative stress. | Benefits are modest and build with weeks of use. |
| Glycaemic support | Links between mitochondrial function and insulin sensitivity; trials report improvements in fasting glucose/HbA1c in subsets. | Coordinate with clinician if using glucose-lowering meds. |
| Skin & healthy appearance | Topical and systemic antioxidant effects may limit photo-aging signals; supports cellular energy in skin. | Combine with sun protection and nutrition. |
| Lungs & neuro | Oxidative stress is implicated in COPD and migraine; CoQ10 may help via antioxidant and mitochondrial pathways. | Discuss with a clinician for personalised use. |
| Statin-related muscle symptoms | Statins reduce mevalonate pathway products; supplemental CoQ10 is sometimes used to support muscle comfort. | Always consult the prescribing physician. |
Skin support: Our product Injuv is an all-natural moisturiser designed to improve skin from the inside; CoQ10’s antioxidant role complements topical and nutritional skin strategies.
Can You Get Enough CoQ10 from Food?
Diet contributes only a fraction of the body’s CoQ10 pool (often estimated at ~3–6 mg/day), which may be insufficient to raise status meaningfully—especially as endogenous synthesis declines with age.
| Food Category | Examples | Notes |
|---|---|---|
| Organ meats | Heart, kidney, liver | Highest natural sources |
| Muscle meats | Beef, pork, chicken | Moderate amounts |
| Fatty fish | Sardine, herring, mackerel, trout | Adds omega-3s for anti-inflammatory support |
| Vegetables & legumes | Spinach, cauliflower, broccoli; soybeans, peanuts, lentils | Lower levels; still valuable for overall health |
Bioavailability: Traditional vs. Liposomal CoQ10
A key challenge with CoQ10 is absorption. Conventional oral forms show modest bioavailability; only a small percentage reaches circulation. Advanced delivery systems aim to improve uptake and tissue delivery.
| Feature | Traditional CoQ10 (standard oral) | Liposomal CoQ10 (advanced delivery) |
|---|---|---|
| Absorption | Variable; relatively low oral bioavailability | Designed to enhance uptake via lipid vesicles |
| Onset | Slower; requires higher dosing for effect | Potentially faster and more consistent |
| Tissue delivery | Limited penetration | Formulated to improve membrane passage |
| Use case | General wellness with patient dosing | Optimisation for biohacking and healthy ageing goals |
Why this matters: If traditional forms deliver only a small fraction to circulation, advanced formats like liposomal supplements can be a pragmatic way to raise CoQ10 status without resorting to very high doses.

How to Use CoQ10 (Practical Tips)
- When: Take with a meal containing healthy fats to support absorption; many prefer morning or mid-day with food.
- How much: Common daily ranges are 100–300 mg; discuss personalised dosing with your clinician—especially for cardiac, metabolic, or neurological goals.
- Stacks: Some longevity protocols pair CoQ10 with exercise (boosts mitochondrial biogenesis), PQQ (pyrroloquinoline quinone), and fasting/calorie restriction strategies that support mitochondrial renewal.
- Safety: Generally well-tolerated; coordinate with your healthcare provider if you take anticoagulants, antihypertensives, or glucose-lowering medications.
Product context: Traditional oral CoQ10 has limited bioavailability. Liposomal CoQ10 formulations are designed to improve absorption and cellular delivery.
Skin support: Our Injuv all-natural moisturiser helps improve skin hydration and the visible signs of ageing from the inside, complementary to CoQ10’s antioxidant role.
FAQs
Is CoQ10 actually anti-ageing?
CoQ10 supports mitochondrial energy and antioxidant defense—two levers tightly linked with ageing biology. While it is not a cure-all, maintaining adequate CoQ10 aligns with healthy ageing strategies focused on energy, resilience, and inflammation balance.
How quickly will I notice effects?
Some people report changes in energy or exercise recovery within 2–4 weeks; skin and endurance changes may take longer. Consistency and an absorbable form matter.
Can I get enough from food?
Dietary intakes are typically low (≈3–6 mg/day). Because endogenous production declines with age, diet alone often isn’t sufficient to optimise CoQ10 status.
Ubiquinone vs. ubiquinol—does the form matter?
Both forms interconvert in vivo. The bigger determinant for many users is overall delivery system and absorption rather than redox form alone.
