What is Vitamins C?
Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement. Humans, unlike most animals, are unable to synthesize vitamin C endogenously, so it is an essential dietary component . Vitamin C is required for the biosynthesis of collagen, L-carnitine, and certain neurotransmitters; vitamin C is also involved in protein metabolism [1,2]. Collagen is an essential component of connective tissue, which plays a vital role in wound healing. Vitamin C is also an important physiological antioxidant  and has been shown to regenerate other antioxidants within the body, including alpha-tocopherol (vitamin E) . Ongoing research is examining whether vitamin C, by limiting the damaging effects of free radicals through its antioxidant activity, might help prevent or delay the development of certain cancers, cardiovascular disease, and other diseases in which oxidative stress plays a causal role. In addition to its biosynthetic and antioxidant functions, vitamin C plays an important role in immune function  and improves the absorption of nonheme iron , the form of iron present in plant-based foods. Insufficient vitamin C intake causes scurvy, which is characterized by fatigue or lassitude, widespread connective tissue weakness, and capillary fragility [1,2,4,6-9]. The intestinal absorption of vitamin C is regulated by at least one specific dose-dependent, active transporter . Cells accumulate vitamin C via a second specific transport protein. In vitro studies have found that oxidized vitamin C, or dehydroascorbic acid, enters cells via some facilitated glucose transporters and is then reduced internally to ascorbic acid. The physiologic importance of dehydroascorbic acid uptake and its contribution to overall vitamin C economy is unknown. Oral vitamin C produces tissue and plasma concentrations that the body tightly controls. Approximately 70%–90% of vitamin C is absorbed at moderate intakes of 30–180 mg/day. However, at doses above 1 g/day, absorption falls to less than 50% and absorbed, unmetabolized ascorbic acid is excreted in the urine . Results from pharmacokinetic studies indicate that oral doses of 1.25 g/day ascorbic acid produce mean peak plasma vitamin C concentrations of 135 micromol/L, which are about two times higher than those produced by consuming 200–300 mg/day ascorbic acid from vitamin C-rich foods . Pharmacokinetic modeling predicts that even doses as high as 3 g ascorbic acid taken every 4 hours would produce peak plasma concentrations of only 220 micromol/L . The total body content of vitamin C ranges from 300 mg (at near scurvy) to about 2 g . High levels of vitamin C (millimolar concentrations) are maintained in cells and tissues, and are highest in leukocytes (white blood cells), eyes, adrenal glands, pituitary gland, and brain. Relatively low levels of vitamin C (micromolar concentrations) are found in extracellular fluids, such as plasma, red blood cells, and saliva .
The History of Vitamins C
Humankind has long suffered from a lack of understanding of basic nutrition. Scurvy was among many diseases suffered due to malnutrition. It wasn’t until the 1930’s that Albert Szent-Györgyi discovered the chemical ascorbic acid—also known as vitamin C—that enables the body to efficiently use carbohydrates, fats, and protein. His discovery was among the foundations of modern nutrition. Those sitting down to nutritious meals usually do not consider what would happen if fresh vegetables and fruit or vitamin-supplemented juices and cereals were not routinely available. Centuries ago, sailors experienced such a lack first-hand: swollen and bleeding gums, loose teeth, hemorrhaging under the skin, and slowed healing of wounds. What we now know as vitamin C was in short supply on most ships, and human bodies reacted by developing the condition known as scurvy. Death could, and often did, quickly follow, thousands of miles away from otherwise life-sustaining provisions. Scurvy had long been the scourge of those who sailed for extended distances without fresh food and supplies, with the first clear-cut descriptions of the malady appearing in the medieval records of the European Crusades. Toward the end of the 15th century, scurvy was cited as the major cause of disability and mortality among sailors on long sea voyages. Although Danish mariners were long acquainted with the condition, and included lemons and oranges in their marine stores, it was not until 1753 that scurvy was recognized in the British medical community at large as directly related to dietary deficiency. In 1769, William Stark, a young British physician, began a series of experiments on diet and nutrition, using himself as the experimental subject. After consuming only bread and water for 31 days, Stark added other foods to his diet one by one, including olive oil, figs, goose meat, and milk. In two months, Stark recorded that his gums were red and swollen, bleeding easily to the touch. Seven months later he died, possibly from scurvy, and likely from the cumulative effects of malnutrition. Stark’s diet was heavy on meat and starch, but devoid of fresh vegetables and citrus fruits. Twelve years before Stark’s ill-fated experiments, Scottish physician James Lind, having observed the preventive and curative powers of citrus fruits and lemon juice during his years as a naval surgeon, wrote a treatise recommending their mandatory consumption by British sailors. By 1795, Lind’s advocacy had resulted in the issuance of lime juice to all naval vessels and the gradual elimination of scurvy within the entire British fleet. At the time, no one, including Lind, knew of the existence of ascorbic acid, which would eventually become commonly known as vitamin C. It would take more years to pinpoint the scurvy-prevention substance responsible for maintaining the body’s connective tissues. That would take the meticulous work of a brilliant Hungarian-born researcher named Albert Szent-Györgyi, whose isolation and identification of vitamin C and discovery of the metabolic mechanism that enables its use within cells would be recognized with a Nobel Prize in Physiology or Medicine. Vitamin C and the Body Vitamin C enables the body to efficiently use carbohydrates, fats, and protein. Because vitamin C acts as an antioxidant — a nutrient that chemically binds and neutralizes the tissue-damaging effects of substances known as free radicals — it is vital to the growth and health of bones, teeth, gums, ligaments, and blood vessels. Vitamin C also plays a key role in the formation of collagen, the body’s major building protein, and is therefore essential to the proper functioning of all internal organs. Vitamin C is found in various foods, including citrus fruits such as oranges, lemons, and grapefruit; in green vegetables such as spinach, broccoli, and cabbage; and in tomatoes and potatoes. Food processing may degrade or destroy vitamin C, as can exposure to air, drying, salting, cooking (especially in copper pots), or processing. (Freezing does not usually cause loss of vitamin C unless foods are stored for a very long time.) In modern times, access to fresh fruits and vegetables is common, rendering full-blown cases of vitamin C deficiency relatively rare. Cases are normally limited to isolated elderly adults, usually men whose diet is limited to foods lacking in vitamin C, as well as to infants fed reconstituted milk or milk substitutes without a vitamin C or orange juice supplement. Those with certain illnesses, such as AIDS, cancer or tuberculosis, surgical patients, and those exposed to long periods of cold temperatures can also suffer from vitamin C insufficiency.
The Top 4 Reasons You Need Vitamins C
The most commonly cited lecithin benefits include:
1. Improves Heart Health As per one American study, vitamin C might play a role in reducing heart disease risk. Multiple cohort studies have demonstrated that higher plasma levels of vitamin C could be linked to reduced heart disease risk (1). More studies state that vitamin C could be as good as exercise for your heart. A regular dose of vitamin C can hinder the activity of a protein named endothelin-1, which leads to the constriction of small blood vessels – and this eventually causes heart attack (2). The vitamin can also lower your blood pressure and keep your arteries flexible. 2. Regulates Blood Pressure Levels As per a report by Johns Hopkins Medicine, large doses of vitamin C can lower blood pressure. This function of vitamin C could be attributed to its physiological and biological effects. Vitamin C acts as a diuretic and causes the kidneys to remove more sodium and water from the body – this relieves the pressure on blood vessel walls (5). Vitamin C also protects your body’s supply of nitric oxide, a molecule known to relax the blood vessels (6). The blood pressure lowering effect can be attributed to supplements as well – consuming vitamin C supplements in a dose of 500 mg in a day could reduce systolic blood pressure by 4 points and diastolic blood pressure by 1.5 points – in a period of 2 months (7). 3. Treats Viral Infections According to a study, high dose intravenous vitamin C can be effective in treating allergies. In the past, such doses were used to treat infections like measles, herpes, mumps, and viral pneumonia. This shows the efficacy of vitamin C as an antibiotic (34). Also, since vitamin C is an antioxidant, it combats the harmful free radicals and helps treat viral infections. A high dose of vitamin C was also found to aid in the treatment of mononucleosis (an abnormally high proportion of white blood cells that causes glandular fever) (35). It also fights the free radicals (as already discussed) that might lead to mononucleosis. 4. Improves Your Mood Studies on hospitalized patients have proved that taking adequate amounts of vitamin C can improve mood. It has mood-elevating effects (44). Vitamin C supplementation was also found to reduce anxiety in students (45). 5. Boosts Energy Boosts Energy Vitamin C was found to help you push through the pain barrier and eliminate fatigue. Supplementing vitamin C had also made the training of school footballers about 10% easier and reduced fatigue by as much as 55%. In another Korean study, vitamin C had significantly reduced work-related fatigue in healthy employees (47). Vitamin C supplementation was also found to improve physical activity levels in men who had marginal vitamin C status (48).
2. Boosts Immunity A deficiency of vitamin C reduces the body’s resistance against certain pathogens (9). As per a study, vitamin C stimulates the immune system by enhancing the strength and protection of the organism (10). In addition to protecting the immune system, vitamin C also reduces the severity of various allergies and fights off infections. It achieves this by enhancing T-cell proliferation in response to the infection (11). It has also been found that individuals suffering from wounds could accelerate their healing process by an optimal dose of vitamin C (12). The nutrient had improved the quality of the newly synthesized collagen, thereby quickening the process of wound healing. And coming to common cold, though more research is required, vitamin C has been found to reduce the duration of the cold (13). We don’t know yet if the vitamin can protect against a cold – but it sure does reduce how long the cold lasts. Vitamin C might also be a potential treatment for asthma (14). However, more research is required in this aspec
3. Helps Prevent Cancer Numerous laboratory studies have shown that high doses of vitamin C can slow down the growth of prostate, liver, colon, and other types of cancer cells (15). Higher concentrations of vitamin C might also help in cancer treatment. The intravenous administration of a type of vitamin C to inoperable patients with cancer resulted in a significant reduction in tumor volume without any side effects. Ascorbate also killed cancer cells, as noted in numerous studies (16). Another report by Cornell University had stated that vitamin C halts aggressive colorectal cancer (17).
4. Aids In The Treatment Of Osteoarthritis According to the Arthritis Foundation, vitamin C can help prevent some forms of arthritis. But too much of it might worsen some other forms of the condition – which is why finding a balance is key. Getting the right dose of vitamin C helps prevent inflammatory arthritis and maintains healthy joints with osteoarthritis (18). Research also states that people with the lowest levels of vitamin C would be three times more likely to develop inflammatory arthritis (19). But as we already discussed, taking note of the dosage is important. Dietary intake of vitamin C exceeding the RDA recommendation (90 milligrams per day for men and 75 milligrams per day for women) might worsen arthritis symptoms (20).
Shocking Facts About Vitamins C
Many of the facts on vitamin C is known because for many people it is usually the first vitamin they learn about at school. Vitamin C fact #1. The first fact we have about vitamin C is that we are one of the few mammals that do not manufacture our own vitamin C through an enzymatic glucose conversion process. This is because we (together with other primates) have lost this ability and we must therefore absorb the nutrient from external dietary sources. Vitamin C fact #2. The next fact we have on vitamin C is that because it is a water-soluble vitamin, your body will get rid of any excess within a 24-hour period of consumption. The fact that your body cannot store vitamin C means that you need your vitamin C from your meals and drinks every day. Vitamin C fact #3. One more facts on vitamin C is that humans vary greatly in their vitamin C requirement. It's possible for one person to need 10 times as much vitamin C as another person. The main reasons for this wide variation can be attributed to a person's age and health status. Vitamin C fact #4. Our next vitamin C fact relates to how it interacts with other nutrients. Like many vitamins and minerals, vitamin C is most effective when combined with other nutrients because it has significant interactions with several key minerals in the body. Vitamin C can for example significantly improve your ability to digest and absorb the essential mineral iron. It is also involved in the regeneration of vitamin E and these two vitamins appear to work together in their antioxidant effect.
The Benefits of Vitamins C
You may already know about all the amazing things vitamin C can do for your system. It helps to promote healthy bones and teeth, it boosts overall immunity, and it has even been shown to help lower blood pressure. But did you know how many amazing things it can do for the way you look? Collagen is the main structural protein found in your skin and connective tissue. In fact, 70% of all the protein found in your skin is collagen. It’s responsible for the elasticity of your skin, and keeps everything looking young and fresh. How do we get collagen? By taking in Vitamin C. Your body needs vitamin C to produce collagen, and you need collagen for healthy skin. Vitamin C is an antioxidant, which your body uses to fight off harmful free radicals. Many of these are produced when ultraviolet radiation from the sun comes into contact with your body, and a lack of vitamin C can leave you with a reduced ability to fight them off naturally. Now, don’t go skipping your sunscreen, but studies do show that people who get enough vitamin C have less overall sun damage to their skin.
Why Vitamins C Is The #1
A deficiency in vitamin C shows itself in several common ways in the body. While the signs and symptoms of Vitamin C deficiency are not too bothersome, the results of long-term low levels of vitamin C are very detrimental and worth making a priority. A severe vitamin C deficiency will result in scurvy, a disease resulting from the breakdown of collagen. Scurvy will make you feel fatigued and lethargic. It affects bone and muscle strength and it stifles the immune system. Scurvy is rarely seen today, as only a very small amount of vitamin C is needed to prevent it. Citrus was actually used in the 18th century in order to cure the two million sailors that were suffering from Scurvy. It is important to understand, however, that less noticeable signs of Vitamin C are still very serious such as: • Easy bruising • Swollen gums • Bleeding gums • Slow wound healing • Gingivitis (inflammation of the gums) • Dry and splitting hair • Dry red spots on the skin • Rough, dry, scaly skin • Nosebleeds • Weakened immune system • Digestive disorders like leaky gut and autoimmune disease • Possible weight gain because of slowed metabolism • Swollen and painful joints • Health problems related to a vitamin C deficiency can get much worse over time, and may lead to some serious health issues. Long Term Problems from Low Levels of Vitamin C include: • High blood pressure • Gallbladder disease • Stroke • Certain cancers • Atherosclerosis To get the most nutrition and Vitamin C from your fruits and veggies, there are a few easy tips to follow: eat real foods that are uncooked and raw, make an effort to eat your fruits and vegetables soon after cutting them up, and steam fruits and veggies, instead of boiling them. As I always say, eating organic, raw fresh foods is your best possible source of nutrition. Food in its natural state will provide your body with the most abundant source of nutrition, so even though many people choose to turn to supplements when looking to get more vitamins into their bodies, I want to emphasize that the best source of any vitamin, mineral, or nutrient is fresh, raw food sources.
Top 3 Questions People Ask About Vitamins C
There are a few frequently asked questions about these Vitamins C.
1. How much vitamin C should I take? Your optimal dose of vitamin C depends on one thing: you. Are you healthy? Stressed? Sick? In sickness it was observed by Robert F. Cathcart, III, MD, that, "The amount of oral ascorbic acid (vitamin C) tolerated by a patient without producing diarrhea (loose bowels) increases somewhat proportionately to the stress or toxicity of his disease" and "[s]tressful conditions of any kind greatly increase utilization of vitamin C." In other words, the sicker or more stressed you are, the more vitamin C you will "hold" before getting to saturation (bowel tolerance). Bowel tolerance is indicated by gas, a rumbling stomach, or slightly loose stool. If you take way too much C, very loose stool will result, but this goes away once dosages are reduced. When bowel tolerance is reached, this is a sign to back off the extra C. We continue to take C, but we take less and less often. It may take days to resolve illness (it depends how sick we are) but when healthy, the body needs less and "holds" less C.
I take 8,000-10,000 milligrams (mg) of vitamin C orally a day when I am healthy. I take far more when I am under stress. If I am really sick, I may take up to 100,000 mg of vitamin C a day. Two-time Nobel Prize winner Linus Pauling took 18,000 mg of vitamin C a day, and he recommended taking 6,000 to 18,000 mg per day. For healthy children, Frederick R. Klenner, MD, recommended 1,000 mg per day per year of age, leveling off at 10,000 mg per day when the child reaches ten years of age. He recommended far more during illness. For example, in good health, my five-year-old gets 5,000 mg of vitamin C a day and perhaps 25,000 mg per day when sick. We always divide our doses of vitamin C and take it throughout the day. "The effects of this substance (vitamin C) when used in adequate amounts markedly alters the course of many diseases," said Dr. Cathcart. To read his important paper about bowel tolerance doses of vitamin C as it pertains to specific illnesses see:
2. I'm confused about vitamin C frequency and dose. Can you help? I find vitamin C dosing takes some getting used to. If I am sick, stressed, etc., I take vitamin C in divided doses until bowel tolerance (saturation) is reached. Then I continue to take C but less, and less often. So for me, when sick, I may start the day with 8,000 mg and then take 2,000 to 4,000 mg every hour until I experience saturation indicated by a rumbling tummy and/or loose stool. Once saturation is reached, I may still have some symptoms of illness, but they are improved and I feel better. I continue to take saturation level doses of C until I am symptom free, and yes, sometimes it may take a few days depending on how sick I am. When I am healthy, I regularly take 8,000 to 10,000 mg per day in divided doses, approximately 3,000 to 4,000 mg at each meal. (When I am healthy, if I took that 8,000 mg all at once it would be a quick trip to the toilet for sure. But when I'm sick I can "hold" a very large amount of C and can take larger doses.) The optimal amount may differ for other people.
3. How much vitamin C is needed to treat colds and flu? According to Robert F. Cathcart, MD, the usual bowel tolerance doses for a mild cold could be somewhere between 30,000 mg to 60,000 mg of vitamin C per day given in divided doses. A person with a severe cold might take 60,000 mg to 100,000 mg per day before reaching bowel tolerance. The flu? Up to 150,000 mg daily might be taken in divided doses to achieve bowel tolerance. And for all those folks who feel great? Taking 4,000 mg to 15,000 mg per day could be enough to get to bowel tolerance. Stress, sickness, infection, vaccinations, postpartum or post-surgical healing, etc., indicates a need for far more. Again, here is a link to Dr. Cathcart's important paper on bowel tolerance. The entire paper is worth reading. Scroll down to see the dosage chart for vitamin C. Note that the doses on his chart are given in grams and that 1 gram = 1,000 milligrams (mg):
Tips for a Vitamins C
At my first job out of college, I had a boss who ate a whole grapefruit for breakfast every morning, without fail. I always knew that grapefruit was good for you, but I couldn't understand how she didn't get bored. I still don't completely get it, but now that I know more about nutrition, I see why she would make a point of having a grapefruit every day. Grapefruit is one of the best fruit sources of vitamin C, with about 88 milligrams of the good stuff. And, because this important vitamin is water soluble, it is important to get it from food (or drink) daily. Water soluble vitamins don't stick around very long in our bodies. The body absorbs what it needs at the time, and the rest is washed away in your urine. (Fat soluble vitamins last much longer.) Vitamin C is a powerful antioxidant, which means it could help fight the free radical damage in your body. This vitamin is also associated with a reduced risk of chronic diseases, such as cancer, cardiovascular disease and cataracts, according to a 1999 study in the American Journal of Clinical Nutrition. A study this year in the same journal found that vitamin C might also help reduce blood pressure, in addition to the myriad of other health benefits. It's important to note that this study didn't control for other factors, such as blood pressure medication, so more research must be done. Still, it probably wouldn't hurt to get a little more vitamin C in your diet. Here are some tips for getting the most vitamin C out of your daily diet: • Eat your fruits and veggies raw whenever possible. When you cook them, youstrip the food of some of its vital nutrients. Cooking especially affects water soluble vitamins, such as vitamin C. • Keep a bowl of vitamin-C rich fruit in the house for snaking. A grapefruit for breakfast is not a bad idea. You may also consider eating more oranges, mangos and kiwifruit. • Have a light lunch with a side of crudité. Raw broccoli and red peppers are extremely high in this powerful antioxidant. • Eat more fermented vegetables. One serving of kimchi (a traditional Korean recipe made of fermented cabbage) provides about half of your recommended daily value of vitamin C. Sauerkraut is also a good option; just be sure to buy it in the refrigerated section. In addition to vitamin C and other vitamins, kimchi and sauerkraut also contain gut-strengthening probiotics.
