Coenzym Q10—how it supports your health and how to optimise your intake

Have you ever caught yourself yawning midday and wondering, “Where on Earth did all my energy go?” Well, there’s a chance Coenzyme Q10—often shortened to CoQ10—might be part of that conversation. Picture CoQ10 as your body’s tiny assistant, hustling behind the scenes to keep cells energized and shield them from harm (though, to be fair, the science is still evolving). Below, we’ll explore the basics of this fascinating compound, how it supports your health, and how you might work it into your daily life—without going overboard.

What exactly is CoQ10?

CoQ10 (sometimes called ubiquinone) is a nutrient that’s mainly found in your mitochondria (think of these as your cells’ power plants). It’s basically a big player in creating ATP, the energy currency of our bodies. But there’s more: CoQ10 also happens to be a potent antioxidant that helps defend your cells against free radicals—those unruly molecules that can damage DNA, proteins, and cell membranes. It’s like having a built-in bodyguard, although, admittedly, not an all-powerful one.

Why do we need it?

  • Energy production: CoQ10 helps ferry electrons around in the mitochondria, enabling ATP formation (i.e., the stuff that keeps our muscles moving and our brains thinking).
  • Antioxidant power: By neutralizing free radicals, CoQ10 might reduce the oxidative stress that has been linked to heart disease, neurodegenerative disorders, and, you know, the general wear-and-tear of daily life.
  • Age and medication factors: Our natural CoQ10 levels can decline with age or when taking certain drugs (like statins). That means some folks turn to supplements to keep levels up—though whether this is essential for everyone is still a topic of debate.

Where do you get CoQ10?

Food sources

Despite its scientific-sounding name, CoQ10 is actually present in many everyday foods:

  • Organ meats (liver, heart): A powerhouse of nutrients, organ meats boast some of the highest CoQ10 concentrations. Not everyone’s cup of tea, but still.
  • Fatty fish (salmon, tuna, mackerel): These varieties contribute notable amounts of CoQ10, plus healthy fats to boot.
  • Meat, nuts, seeds: Muscle meats (beef, pork, chicken) and plant-based snacks (like peanuts, pistachios, or sesame seeds) add moderate CoQ10 to your diet.
  • Spinach and broccoli: These veggies won’t drown you in CoQ10, but they contribute a fair share—plus a host of other vitamins and minerals.
  • Oils (olive, corn, soybean): Frequently used in cooking, these oils also contain CoQ10, though not in sky-high amounts.

Supplementation

Sure, you might get enough CoQ10 from a balanced diet if you’re a big fan of organ meats and fish. But not everyone loves liver on toast, and that’s okay. Enter CoQ10 supplements, which come in several forms (soft gels, capsules, tablets, and so on). People often seek these out to address:

  • Statin-related depletion: Statins, commonly prescribed for high cholesterol, can reduce CoQ10 in the body, prompting some doctors to suggest supplementation.
  • Age-related declines: Because our natural CoQ10 levels may slip as we get older.
  • Chronic health concerns: Heart issues, migraines, or certain neurodegenerative conditions (like Parkinson’s) sometimes nudge folks toward exploring CoQ10.

Potential health perks (with a side of caution)

Researchers have taken a keen interest in CoQ10 for several reasons, though the verdict can be a bit mixed—like a patchwork quilt of promising findings and inconclusive data. Let’s look at some highlights:

  1. Heart health:
    • Some studies connect CoQ10 supplementation with improvements in heart failure management and blood pressure. It might help energize cardiac cells and combat oxidative stress in the cardiovascular system.
    • Still, not every study has shown dramatic benefits. So, proceed with optimism and a dash of skepticism.
  2. Migraine management:
    • Lower CoQ10 levels have been linked to an uptick in migraine headaches. Taking supplemental CoQ10 may lessen how often these headaches occur or shorten their duration.
    • The effect size varies person to person, so don’t skip your migraine prescriptions without a doctor’s go-ahead.
  3. Neurological protection:
    • Because of its antioxidant punch, CoQ10 appears promising in certain neurodegenerative disorders (like Alzheimer’s or Parkinson’s). It’s thought to protect neurons from damage and shore up mitochondrial function.
    • Early research is encouraging, though more controlled trials are definitely needed before hailing CoQ10 as a new silver bullet.
  4. Diabetes support:
    • A handful of small studies hint that CoQ10 might help balance blood sugar levels or improve lipid profiles.
    • Larger, longer-term research is crucial to nail down whether these effects are real and clinically meaningful.
  5. Skin health:
    • Skincare aficionados might notice more products touting CoQ10. The antioxidant properties could help fend off UV-induced damage and signs of aging.
    • Remember, topically applied CoQ10 vs. oral supplementation might act differently—one size doesn’t fit all here.

CoQ10 supplements: a quick primer

Forms and absorption

  • Ubiquinone vs. Ubiquinol: Ubiquinol is often labeled as the “more bioavailable” version, especially for older adults. Some feel it’s worth the extra cost; others are fine with standard ubiquinone.
  • Dosage: Typical daily intakes range from 30 mg to 200 mg. Higher doses (like 400 mg or more) appear in some studies, but it’s wise to consult a healthcare professional before experimenting with bigger amounts.

Where to get CoQ10 supplements?

When it comes to sourcing food supplements, plenty of reputable companies exist, each with its own unique spin on quality and formulation. Names like

are often cited for their commitment to ingredient purity and rigorous testing methods, although standards can vary across the board. You might also stumble upon Garden of Life, Jarrow Formulas, or Life Extension, which emphasize transparent labeling, third-party certifications, and sometimes even non-GMO or organic seals. Of course, it’s smart to dig a little deeper into manufacturing practices and customer reviews if you want to be absolutely sure a particular brand aligns with your health goals. After all, supplements are only as good as the care and science that go into making them—and, you know, how they fit into your overall lifestyle.

Safety and Interactions

CoQ10 is generally seen as safe and well-tolerated, with rare reports of mild side effects (like upset stomach or headaches). However:

  • Medication interactions: Blood thinners, insulin, and certain chemotherapy drugs might not play nicely with CoQ10.
  • Pediatric use: The data is still thin regarding children, so medical advice is key if you’re considering CoQ10 for a youngster.
  • Consistency Counts: Taking your supplement with a meal—especially one containing some healthy fats—can help boost absorption.

Research roundup

To be honest, the literature is a bit all over the map. Some robust meta-analyses suggest CoQ10 helps in conditions like heart failure and fatigue. Other research is less convincing, showing mild or no benefit in certain scenarios (e.g., some psychiatric disorders). In my own social circle, I’ve heard glowing reviews from a friend dealing with chronic fatigue—yet another acquaintance said they noticed zero difference. So it’s not a guaranteed homerun, but it might be worth discussing with your doctor if you have a relevant condition.

Cooking and preparation tips

Yes, you can get CoQ10 from real food - if that’s your thing. Here’s how to keep it as intact as possible:

  • Opt for gentle cooking methods: Baking, grilling, or sautéing tends to preserve CoQ10 better than boiling. Imagine a sizzling pan of beef liver with onions or a grilled salmon fillet - both potentially rich in CoQ10.
  • Plant-based picks: If liver isn’t in your top five favorite foods, legumes (like lentils), nuts, and seeds can help bolster CoQ10 intake for vegan or vegetarian diets.
  • Pair with healthy fats: This nutrient is better absorbed when fat is present, so drizzle some olive oil or toss in some avocado to amp up absorption.

Final thoughts

CoQ10 stands at the intersection of energy metabolism and antioxidant defense, making it a nutrient of keen interest for anyone curious about heart health, brain function, or plain old vitality. While many studies point to potential benefits, others are inconclusive or show only modest gains—so we’re still unraveling the full story.

If you’re thinking about boosting your CoQ10 through diet or supplements, consider checking in with a healthcare professional first. After all, no single supplement (or miracle pill) can outdo a balanced lifestyle that includes nutritious meals, regular exercise, adequate sleep, and stress management. In the meantime, keep an open mind and remember: science evolves, and so should our approach to well-being.

Pressing pause on aging?

A ton of hype—and equally high hopes. What’s going onFrom high-profile Instagram influencers to billionaire investments, the quest for a “fountain of youth” is big business. US tech entrepreneur Bryan Johnson claims to swallow more than 100 pills a day, while research teams worldwide test potential “longevity” drugs—think rapamycin, metformin, senolytics, or GLP-1 receptor agonists. Key takeawaysLifestyle still reigns: Studies repeatedly show that not smoking, limiting alcohol, getting enough sleep, and eating a balanced diet can add years—even decades—to one’s life.Genes vs. pills: Many dream of a simple longevity pill, but genes and healthy habits usually have a stronger impact.Blue zones and centenarians: Places like Okinawa or Sardinia boast unusually high numbers of 100-year-olds—though skeptics argue administrative errors may inflate these stats.Money and skepticism: From NAD+ or glutathione IV drips to plasma infusions, countless “anti-aging” offers exist—but most lack solid human trial evidence. Experts warn against overstated promises.Why it mattersWhether you call it geroprotection or anti-aging, halting the aging process has gripped humanity for centuries. Billionaire-backed labs test new therapies, while social media swarms with expensive “youth-restoring” treatments. But the bottom line remains: basic healthy habits often outweigh any miracle cure.Looking ahead Extending “Health Span”: The goal isn’t just to live longer, but to live better, avoiding debilitating diseases in old age.A pill vs. ice baths?: Future meds might slow aging’s clock—though their real-world impact is yet unknown.Societal implications: Lifespans are rising, as are the years spent in poor health. Policymakers and scientists hope new therapies can compress those frail years—worth billions if proven effective.

Testosterone and longevity: how hormone levels impact our quality and length of life

Testosterone is often seen as a symbol of masculinity, strength, and vitality. But what if I told you that this hormone also plays a crucial role for longevity in men?Indeed, low levels of testosterone were linked to a shorter life span, in a recent study (1). And, as we age, the apparent effects of testosterone on our health, mood, and well-being become even more significant.In the following, we will explore how testosterone influences longevity and what you can do to optimize your hormone levels for a longer, healthier life. What is testosterone and why does it matter? Testosterone is a vital hormone for both men and women. It is primarily produced in the testes in men, in the ovaries in women, and in the adrenal gland in both sexes. It’s crucial for muscle growth, bone density, libido, and the regulation of mood. But beyond these commonly known roles, testosterone also affects cognitive function, cardiovascular health, and metabolic processes, all of which are key players in how “well” we age.As men reach their 30s, testosterone levels begin to decline, typically by about 1% each year (2). While subtle at first, this decline can significantly affect health, leading to decreased energy, loss of muscle mass, mood fluctuations, and reduced libido. This is especially concerning given that up to 40% of men today are affected by testosterone deficiency (3).On the other hand, maintaining optimal testosterone levels has been associated with both a longer lifespan and an extended health span - that is, the number of years lived in good health (4,5). Over the past years, we have worked closely with hundreds of men to optimize their hormone levels, and the impact on key longevity markers has been strikingly clear. Let me explain in more detail:The connection between testosterone and longevity Testosterone’s influence on bodily functions has been extensively studied, and several key findings highlight its critical role in longevity: Muscle mass and metabolism: Testosterone plays a direct role in building and maintaining muscle mass. As we age, muscle loss accelerates, contributing to frailty and a decrease in overall vitality. Testosterone helps prevent this by promoting muscle protein synthesis and supporting metabolic function. This is particularly important because muscle mass is not only a sign of strength but also a key factor in metabolic health and weight management.Cardiovascular health: Testosterone also plays a crucial role in cardiovascular health. Research suggests that optimal testosterone levels help maintain healthy cholesterol levels, improve blood circulation, and even promote the production of red blood cells. Low testosterone has been associated with a higher risk of cardiovascular disease. The aforementioned recent Australian study involving nearly 25,000 men further reinforced this link, directly connecting testosterone deficiency to increased cardiovascular mortality (1).Bone health: Osteoporosis is an often overlooked condition in men. The disease is closely associated with aging, however the role of testosterone in the development of the disease is frequently underestimated. Testosterone is being aromatized to estrogen, which has a significant impact on bone density. Studies show that men with low testosterone levels tend to have lower bone mineral density and a higher risk of fractures. Ensuring adequate testosterone levels can thus help maintain bone health, reducing the risk of falls and fractures as we age.Mental health and cognitive function: Testosterone isn’t just about physical health, it also affects your mental well-being. Low levels of testosterone have been linked to depression, fatigue, and cognitive decline. On the other hand, maintaining healthy testosterone levels can improve mood, cognitive function, and overall mental clarity, helping you stay sharp well into your later years. Many of our patients report symptoms like brain fog and difficulty concentrating, which often disappear once hormonal imbalances are corrected.The downside of low testosteroneTestosterone deficiency is no longer just a condition of aging men. Today, around 20% of young men suffer from low testosterone levels, and research suggests that this trend is continuing to worsen (6). The symptoms can be wide-ranging and often impact daily life. Common complaints include:Decreased energy and motivationLower libido and sexual dysfunctionIncreased body fat and decreased muscle massPoor mood, irritability, and even depressionDifficulty concentrating or memory problemsThese symptoms not only affect quality of life but can also contribute to other health issues like obesity, diabetes, and cardiovascular disease—a well-published phenomenon. Recognizing the signs of low testosterone and addressing them early can significantly improve overall well-being.How to optimize testosterone naturallyFortunately, there are several effective ways to naturally optimize testosterone levels, supporting both health and longevity. Interestingly, the typical age-related decline (starting in the 30s for most men) is often not observed in those who maintain a healthy lifestyle and remain free from chronic diseases. To my knowledge, the most powerful strategies to sustain optimal testosterone levels include:Regular exercise: Physical activity is one of the most effective ways to ensure healthy testosterone levels. Strength training, high-intensity interval training, and aerobic exercises can all increase testosterone production. Regular exercise also helps maintain muscle mass, supports cardiovascular health, and improves metabolic function.Nutrient-rich diet: A healthy diet rich in essential nutrients is crucial for maintaining healthy testosterone levels. Foods high in zinc (like pumpkin seeds and lean meats), vitamin D (such as fatty fish and eggs), and healthy fats (like avocados and olive oil) support hormone production. Avoiding excessive sugar and processed foods can also help maintain stable testosterone levels.Sleep hygiene: Sleep is a powerful tool in hormone regulation. Testosterone production peaks during deep sleep, so it’s essential to prioritize quality rest. Aim for 7–9 hours of sleep each night, and ensure your sleep environment is conducive to deep, uninterrupted rest (i.e., keep it cool and dark).Manage stress: Chronic stress can significantly affect testosterone levels by increasing cortisol, a hormone that negatively impacts testosterone. Managing stress through practices like meditation, yoga, mindfulness, and sports can help lower cortisol levels and support healthy testosterone production.When to consider medical interventionWhile natural methods can help optimize testosterone levels, some men may need medical intervention. Testosterone replacement therapy (TRT) is a treatment option for those with significantly low testosterone levels, particularly when lifestyle changes are insufficient. TRT can improve energy, mood, and physical health by restoring testosterone to normal levels. Over the years, I have been truly fascinated by the profound impact it can have on men, often transforming their vitality, confidence, and overall well-being. However, it’s important to approach TRT with caution, as it comes with potential side effects, including benign prostate enlargement, mood swings, and increase in red blood cells. It’s essential to work closely with a healthcare provider to assess whether a TRT is appropriate for you, taking into account your individual health conditions and goals.Finding balanceThrough our work with hundreds of men, I have witnessed firsthand the profound impact that testosterone optimization can have, not just on energy, mood, and strength. I truly believe that testosterone plays a crucial role in how well we age, and there is much to be learned from its effects on long-term health. By maintaining optimal testosterone levels through natural lifestyle changes, you can significantly enhance your quality of life and potentially extend your health span. However, it’s essential to approach testosterone optimization with balance—too little can be detrimental, but too much can also have negative effects. In the end, maintaining healthy testosterone levels is just one piece of the longevity puzzle. A holistic approach that includes regular exercise, a nutrient-rich diet, stress management, and quality sleep is, in my view, the key to living a long, strong, and fulfilling life.
