Vitamin C and Cellular Energy Production


Vitamin C is a water-soluble nutrient that the human body requires for a wide range of functions. Vitamin C, taken in the diet or in vitamin C supplements, promotes wound healing, supports the immune system and is required for proper function of the brain cells. In addition, research indicates vitamin C affects energy production in the body’s cells.

The human body is an electrical system. Body cells use chemical messengers to communicate and control various functions such as growth, repair and the production of important enzymes and hormones. Individual cells have what is known as electrical potential. Each cell is surrounded by a thin membrane that allows ions of minerals like sodium and potassium to cross back and forth based on the concentrations on each side of the membrane. The mitochondria – structures inside the cells – are like tiny powerhouses that regulate energy production. Basically, each cell is a battery that can produce or accept an electrical charge depending on the concentrations of its ions. When vitamin C becomes depleted in the cells, the electrical potential of the cells drops.

Having adequate amounts of vitamin C in the body is critical for health at the cellular level. Humans need at least 40 to 120 milligrams of vitamin C every day and many scientists think higher doses are beneficial. Foods like peppers and citrus supply vitamin C, as do vitamin C supplements.

Vitamin C’s Role in Brain Health


Most people are aware that vitamin C is an important part of a healthy diet and that humans need a regular dose since the body can’t store this vitamin. Vitamin C supports tissue healing and natural collagen production. What is less well-known is the importance of vitamin C to brain health.

Vitamin C – also known as ascorbate – is an antioxidant. It can be obtained from foods like citrus fruits and peppers or through vitamin C supplements. Although the whole body uses vitamin C in various functions, it is of critical importance in the brain. Researchers have found that the body’s highest concentrations of vitamin C are found in the brain and other neuroendocrine tissue. It is also very difficult for the brain to become depleted of ascorbate, suggesting that it is critical for proper brain function. In addition, when vitamin C deficiency (scurvy) occurs, the body holds onto ascorbate in the brain tissue when other tissues become depleted.

Among other functions, vitamin C is used by the brain to produce neurotransmitters, which are chemical messengers the brain cells use to communicate. Neurotransmitters affect the body’s emotions and control important chemical processes such as the “fight or flight” response to stress and danger. Scientists have discovered, for example, that the nerve cells of the eye – the retina is part of the nervous system – must be bathed in ascorbate in order to function properly. The retina contains special cells called GABA receptors, that help control communication between brain cells. Current findings indicate vitamin C is critical for these receptors to function properly; in the absence of vitamin C, the receptors stop working.

The implications of these findings support the long-standing advice from nutritionists and doctors for people to eat or take vitamins C in some form every day. Vitamin C-rich foods include chile and bell peppers, kale, papaya, strawberries, cauliflower and, of course, oranges. Vitamin C supplements are also readily available in various forms.

Vitamin Deficiencies Can Cause Bruising


Everyone suffers bruises from time to time, usually as the result of some sort of blunt-force trauma. Normally, it’s not a serious problem, but excessive bruising can sometimes indicate an underlying issue such as thin skin, weak capillaries or insufficient collagen levels. These conditions may be linked to vitamin deficiencies.

Bruises typically occur when someone bumps into something. The trauma damages capillaries beneath the skin, causing a tiny amount of blood to seep out and leave a darkened area. The older a person gets, the more they tend to bruise. This is because the skin gets thinner and loses a protective layer of fat as people age. Certain medications, such as blood thinners, can also cause people to bruise more. However, another common culprit is Vitamin C deficiency.

Vitamin C is an essential nutrient for the body. It supports the immune system, works as a powerful antioxidant and is necessary for the natural production of collagen. Collagen is a structural protein that aids in the maintenance and repair of blood vessel walls and other connective tissue. When a person does not get enough Vitamin C, their body can bruise more easily. They may also experience joint pain, a weakened immune response and slower healing of wounds.

If a person develops a severe Vitamin C deficiency, known as scurvy, they can also suffer from bleeding gums, the loss of teeth and hair and the degeneration of blood vessels. This condition is relatively rare in the modern U.S., especially given the wide availability of Vitamin C in the diet and  Vitamin C supplements, but it does still occur in some individuals with poor nutritional habits. In order to prevent these health problems, health experts recommend that adults consume at least 60 – 90mg of Vitamin C each day.

In addition to Vitamin C deficiency, insufficient levels of Vitamin K and Vitamin D may also lead to excessive bruising, as they are both essential to the blood coagulation process. Meanwhile, Vitamin B9 and B12 deficiencies can also cause blood vessel damage and increased bruising. While a healthy diet is important for the prevention of vitamin deficiencies, the use of Vitamin C supplements and other supplemental nutrients can give the body an extra layer of protection.

What are the effects of Vitamin C on the liver?


The liver is the largest solid organ in the human body, and it performs over 400 important functions. For example, it manufactures and secretes bile, which helps with the absorption of vitamins and fats, and it creates blood proteins, cholesterol and immune factors. It also acts as a detoxifying filter, protecting the body from toxins introduced through the consumption of alcohol and certain drugs.

In order to perform its essential responsibilities, the liver needs the support of certain nutrients, including Vitamin C. Vitamin C is a natural antioxidant that can protect against the harmful effects of free radicals that build up in the body. This benefit is particularly helpful to the liver, as it is constantly working to clear the body of harmful substances. To give the liver the support it needs, some health experts advocate consuming elevated doses of Vitamin C.

The body cannot make Vitamin C on its own, so it depends on diet and Vitamin C supplements to get what it needs. Vitamin C-rich foods include oranges and other citrus fruits, strawberries, red cabbage, cantaloupe, broccoli, Brussels sprouts, red and green peppers, kiwi and tomato juice. However, Vitamin C supplements can also help support a healthy liver.

Vitamin C is generally considered very safe at high doses, but exceeding 2,000mg per day may cause nausea and digestive upset in certain individuals. High doses may also interfere with some medications, including drugs used to treat diabetes, cancer and HIV. It is best to consult a physician before taking high doses of Vitamin C or any other nutrient.

Staying Well Through Winter with the Help of Vitamin C

With winter approaching, the majority of us modify our skincare routines, what we wear, and even what we eat in response to the colder, drier air. Including Vitamin C supplement in your winter routine may help prepare your immune system for the season.  

Vitamin C and Its Relationship to Winter

  • Vitamin C, also known as L-Ascorbic Acid, is the most well-known antioxidant and Vitamin C supplements are the most commonly used supplement.
  • During the winter months, Vitamin C rich fruits are typically out of season. This can make supplements especially helpful for reaching the required daily dose.
  • Since it functions as an antioxidant, C is a well-known supporter of a healthy immune system.
  • The minimum recommended dose of this antioxidant is 60mg per day. It is crucial to ensure you are getting this amount through food or supplements.
  • In addition to Vitamin C, Iron and Vitamin B can also be helpful for staying healthy in the winter months.

Final Thoughts

Instead of crossing your fingers that you stay healthy this winter, make sure you reach the dietary requirements for Vitamin C each day either through food or supplements.

Vitamin C and Workout Recovery


Whether you’re brand new to working out, or a veteran fitness buff, muscle recovery is a key factor in avoiding injury. Did you know that Vitamin C has been proven to aid in workout recovery? Here are a few ways this powerhouse vitamin can keep you from getting sidelined.

1) It Packs an Antioxidant Punch

Antioxidants are nutrients that block damage created by free radicals. Not only can free radicals speed the aging process of our skin, but they can also speed the rate at which our muscles break down. Adding Vitamin C to your health regimen will boost your defense against free radicals and protect your muscles after a hard workout.

2) It Fights Inflammation

Vitamin C helps boost our metabolism. Great for losing weight, but also helpful in blocking proteins that are actually harmful to our bodies. The synthesis of certain proteins can increase the risk of inflammation and infection. The more inflammation, the greater the risk of muscle injury. By blocking the chemical reactions in your body that can lead to inflammation, you’ll experience less muscle soreness and be less likely to experience an injury.

3) It Supports Healthy Immunity

After putting your body through a workout, all of your internal systems are working hard on recovery. During this time, you may experience a temporary dip in your immunity levels. Vitamin C helps support your immune system as a powerful antioxidant.

4) It Helps Reduce Cortisol

Cortisol is a stress hormone that increases during times that our bodies are under stress or extreme exertion. We store excess cortisol, and it can lead to an increase in fat around our midsections. Vitamin C helps lower cortisol levels after a workout, preventing the storage of excess levels and that pesky abdominal fat.

Increasing your Vitamin C intake is a simple way to help your body recover from your workout and prepare you for your next one.

Your Heart Health and Vitamin C

vitamin c suppliements heart health

Vitamin C, also referred to as ascorbic acid, is one of the most well-known antioxidants. Linus Pauling, a two-time Nobel Prize winner, pioneered the majority of research surrounding this powerful vitamin and its numerous health benefits.

More research has been conducted on this antioxidant than almost any other nutrient. For starters, it has been shown to help prolong the onset of cataracts by a decade. It also plays a crucial role in joint, bone, and immune health. Arguably, one of its most important roles is supporting heart health.

Vitamin C and Heart Health

Ascorbic acid provides the heart with a variety of benefits:

  • It enhances the level of natural glutathione in the body and thereby helps prevent coronary artery disease.
  • As a potent scavenger of free radicals, it helps protect arteries.
  • It helps strengthen blood vessels walls by supporting the synthesis of collagen. If collagen is weak, oxidized LDL, heavy metals, and toxins create inflammation in the vascular lining. This is how atherosclerotic plaque begins to form.
  • Vitamin C helps improve vasodilation, the ability of arteries in the heart to widen to accommodate more blood when needed – this is one of the main factors in decreasing the risk of heart disease. It improves vasodilation by increasing Nitric Oxide’s availability. Nitric Oxide is a promoter of vasodilation.

What Does the Research Say?

recent meta-analysis analyzed the effect of antioxidant supplements on arterial stiffness. The results indicated that antioxidant supplements played a significant role in helping to reduce arterial stiffness. However, decreased arterial stiffness was only observed in studies that used ascorbic acid combined with other antioxidants, such as Vitamin E. Additionally, antioxidant supplementation was the most effective in patients that already had low concentrations of Vitamins E and C in their plasma.

How to Obtain It

Vitamin C is classified as an “essential nutrient”. This means it is not manufactured by our body and must be consumed in foods or supplements. Foods rich in this antioxidant include tomatoes, citrus fruits, broccoli, strawberries, watermelon, and kiwis. Vitamin C supplements are another very effective method in meeting your daily requirements for this key vitamin.

While many of us know that Vitamin C helps support a healthy immune system, it also plays important roles in the health and maintenance of other organ systems. From our heart to our skin, let’s take a look at which of our bodies’ systems benefit from a boost in Vitamin C.

Cardiovascular Health

Vitamin C can be a big part of maintaining healthy blood pressure levels. Keeping blood pressure within a healthy range is important to prevent heart disease and reduce the risk of a stroke. In fact, a study from the American Journal of Clinical Nutrition found that people with higher levels of baseline plasma vitamin C had a 42% lower risk for stroke.

Skin Health

Vitamin C is also a factor when it comes to keeping your skin healthy. A double-blind, placebo-controlled study revealed that taking liposomal Vitamin C every day can help your skin age gracefully by increasing skin firmness and reducing the appearance of fine lines and wrinkles.1 This may happen because the body uses vitamin C to produce collagen. Collagen is the most abundant protein in the body. It provides structure to many parts of the body, including bones, skin, tendons and ligaments, and is a key part of connective tissue that helps maintain firm and healthy skin.

Muscular Health

As discussed earlier, Vitamin C is essential to the natural production of collagen, which plays many roles in the muscular system.  Collagen makes up the connective tissue found in tendons and blood vessels, and muscles throughout the body.  Vitamin C may also help reduce the build-up of lactic acid during exercise and promote muscle recovery from normal exercise.
