Whether in the form of a fizzy drink or flavored lozenges, cold and flu preventative supplements almost always highlight vitamin C as one of their key ingredients. So, what's so magical about vitamin C? Also known as ascorbic acid, vitamin C is critical to living healthily. Since the human body cannot spontaneously generate this nutrient, vitamin C must instead be absorbed from outside sources, such as vitamin supplements or foods that are naturally rich in it.

What Does Vitamin C Do?

Commonly found in cold and flu preventative supplements, vitamin C strengthens and speeds up immune system functionality. Though research does not indicate that vitamin C intake alone can prevent the onset of cold or flu, adequate daily intake may shorten the duration of an infection or lessen the severity of symptoms.

Vitamin C is crucial for the maintenance of well being. For example, it plays a role in wound healing and helps maintain many essential body tissues. It also acts as a potent antioxidant and can repair damage from free radicals, which are linked to aging effects, and disease vulnerability. Additionally, vitamin C can also prevent anemia, since it helps the body increase absorption of dietary iron, another vital mineral that the body cannot spontaneously create.

Foods that contain high concentrations of vitamin C have been linked with a lower risk of cardiovascular disease, like heart attack and stroke. Vitamin C can also increase levels of nitric oxide, a compound that widens blood vessels and, in turn, lowers blood pressure. In addition, regular intake of vitamin C, along with other vitamins, has been linked to a decreased risk for developing age-related cataracts, a leading cause of visual impairment in the United States.

Common Sources of Vitamin C

Vitamin C can be easily obtained through the many different foods, including:

• Citrus fruits and juices (orange, grapefruit, lemon, lime and tangerine)
• Berries
• Melons
• Mangoes
• Kiwi
• Tomato
• Broccoli
• Red peppers
• Spinach
• Squash
• Potatoes

Cooking these foods may result in the loss of some of the vitamin content, so it is ideal to ingest them raw, either whole or juiced. Nowadays, there are also numerous packaged food products, like cereals, that have been enriched and fortified with vitamin C, so that the nutrient can be easily obtained.

Vitamin C may also be labeled as "L-ascorbic acid" in supplement form, and most over-the-counter multivitamins contain the recommended daily amount of the vitamin. While it is a good source when an individual is in need of a vitamin C boost, supplements are not meant to replace a diet rich in naturally derived vitamin C.

What Happens When You Have Too Much — or Too Little — Vitamin C?

Vitamin C is a water-soluble vitamin that can be easily flushed out of the body via urination when it is not needed. Therefore, if the main source of vitamin C is from naturally occurring foods, it is near-impossible for excess vitamin C to produce side effects. However, taking excessive concentrated vitamin C supplements may lead to diarrhea or stomach upset.

Since vitamin C-rich foods are so readily available nowadays, symptoms of inadequate vitamin C intake are also rare in the United States. However, malnourished individuals can experience symptoms of vitamin C deficiency over time, including:

• Weakness
• Fatigue
• Anemia
• Easy bruising
• Joint pain
• Skin breakdown
• Weakened tooth enamel
• Gum inflammation

Severe vitamin C deficiency is referred to as scurvy. Scurvy can be easily treated with increased dietary or supplemental vitamin C. Since vitamin C is crucial in the detoxification of the body, a lack of vitamin C can compromise the immune system and make an individual more susceptible to diseases and infections. Individuals with insufficient vitamin C may find that it takes longer than usual to recover from a cold or a physical wound.

Daily Dosage Recommendations:

The daily dosage recommendation for vitamin C is different for everyone, depending on factors such as gender, age, lifestyle and current health condition. The recommended daily dosage for vitamin C is at least 75 mg daily for women and 90 mg for men. Since people who are pregnant, breast feeding, smoking or using oral contraceptives have a lower blood level of vitamin C than others, larger doses of vitamin C may be needed to achieve optimal results in these individuals. Those who have prior or current medical conditions may also require bigger or smaller dosage levels, as recommended by their healthcare providers.

How Much Vitamin C To Take To Prevent Cold

How Much Vitamin C To Take To Prevent Cold

Samantha is an everyday health expert with a background in International Public Health and Psychology. Read full profile

When it comes to vitamins, it can all be a bit confusing as to which ones help prevent which ailment. However, there are some vitamins we can all rely on to know their purpose and preventable abilities, such as vitamin C which is well known for being the best for supporting us through colds and flu. But is this entirely true? Is there a more effective vitamin that can help with preventing us from catching colds and flu?

If latest research is anything to go by, the answer is yes and it may be surprising to hear that it's actually vitamin D. Our ideas of vitamin D are usually synonymous with bone health which is entirely true, but it has emerged that vitamin D has been vastly underestimated in its important role of improving our immune systems.

Vitamin C vs. Vitamin D

While getting enough vitamin C is helpful towards preventing colds, we are led to believe that we need more of it to get better and improve immunity. The real truth is, we get plenty of vitamin C in our diets. Easily obtainable and common foods such as fruits (strawberries, melon, tomatoes and citrus fruits) and vegetables (green leafy vegetables, cauliflower, broccoli and brussels sprouts) all contain high levels of vitamin C so a balanced healthy diet will supply more than enough.

On top of that, vitamin C isn't as effective at improving our immune systems as we are led to believe. While it can help towards fighting a cold, it actually makes little impact.

Latest studies have shown a link between low vitamin D levels and higher cases of common respiratory infections. While it's essential for bone health, vitamin D is multi-purposeful and is thought to be much better than vitamin C in its immunity role. A study was conducted involving 19,000 participants using data from a national health survey between 1988 and 1994. It showed 36% of those with low levels of vitamin D in their blood were more likely to report having a recent upper respiratory tract infection than those with higher levels.

Although these studies are just coming through and more research needs to be done, there are more and more strong links between chances of catching colds and low levels of vitamin D.

Getting Enough Vitamin D for Our Body

The problem is that vitamin D is much harder to produce in the body. With reduced exposure to sunlight in many countries especially in the winter, a large percentage of people have a vitamin D deficiency, therefore not getting the full benefits of what vitamin D can do for their immune systems.

This is why diet and supplements are key to getting the sufficient amount of vitamin D we need in order to help prevent colds and flu more efficiently.

Foods such as egg yolks, canned tuna, liver, cod liver oil, fortified milk, and fortified cereals can give you a boost of vitamin D along with supplements ‒ and a dose of sunlight as vitamin D forms in our skin in response to the sun's rays (just 10 minutes is enough). While upping your vitamin D intake may help towards preventing yourself from getting sick, a consistent daily intake is needed for it to have a successful effect.

Vitamin D and The Common Cold

While more and more research is pointing to increasing your vitamin D levels to fight cold and flu, it's important to realize that it only helps to boost the immune system and isn't a preventative measure in itself. Living a healthy lifestyle with a varied, healthy diet and regular exercise is needed to strengthen our immunity and to ward off the nasty bugs and viruses that get into our body.

The research is promising but it has its limits as to what the ideal level of vitamin D is for supporting immune system responses to infection. All they know is that making the conscious effort to increase depleting vitamin D levels is a must for overall health. So if you want to know how to prevent a cold this winter, reach for the vitamin D instead of the vitamin C and see if it makes a difference.

Vitamin C Cause Gas

15 Foods High in Vitamin C

Fact Checked Updated: Mar 2, 2021

Vitamin C keeps the immune system healthy, helping treat infections, viruses, and other conditions. Although research has not proven that vitamin C prevents the common cold, it can help people recover more quickly, and it may reduce the severity of the virus. Though most people think of oranges and orange juice, vitamin C is in many common foods.

Chili Peppers

Chili peppers can be used to spice up just about any dish, and they up your vitamin C intake, too. In addition to burning your tongue, a half cup of diced chili peppers contains more than 100 percent of your recommended daily vitamin C. They also have plenty of other nutrients, like vitamins A and B6 and potassium. To add chili peppers to your diet, try dicing and putting them into soups, curries or meat dishes for a little extra spice. In addition to vitamin C's effects on viruses, the capsaicin in chili peppers can help to clear nasal passages and relieve headaches during cold season, too.

Strawberries

Strawberries are not just delicious; they are one of the best sources of vitamin C, containing even more than oranges. They're also a great source of folate, antioxidants, manganese, and potassium. Strawberries are easy to add to your diet; they can top yogurt or cereal, sweeten smoothies, make a great, simple snack.

Mangos

If you want to consume more vitamin C, turn to mangos. One cup of diced mango pieces can meet your daily recommended intake of vitamin C. Due to their size, eating an entire mango can provide nearly twice the recommended amount. That boost may help to keep you healthy and decrease viral recovery time. Mangos might not be as popular as apples and oranges in the produce section, but given how much protein, potassium, and vitamins are packed into these fruits, maybe they should be!

Sweet Peppers

If chili peppers are too much, sweet peppers can also provide vitamin C. A half cup of chopped green peppers has up to three times the daily recommended intake of vitamin C, and the more colorful sweet peppers contain more than 100%. Raw vegetables contain the most nutrients, so try snacking on raw slices and low-fat dip or dicing them up for salads. Even cooked peppers retain a lot of their nutritional benefits.

Kohlrabi

This turnip-looking green root vegetable is a member of the cabbage family and a cup gives you more than the recommended daily amount of Vitamin C. Kohlrabi contains many key nutrients, including vitamin C, fiber and antioxidants, potassium, magnesium, and vitamin B6. The sweet, crunchy, lightly flavored veggie is delicious raw, but can also be steamed as a side dish.

Kale

Kale is a superfood because of high levels of vitamin K and vitamin A, but it's also a great source of vitamin C, containing about 130% of the daily recommended amount in every cup. In addition, kale is full of iron, omega-3 fatty acids, and other important nutrients. It's easy to add more kale to your diet by swapping it for lettuce in salads or adding it to smoothies.

Pineapple

A cup of pineapple has more than 75 mg of vitamin C. Pineapples have a lot of bromelain, an enzyme that can help with food breakdown during digestion, improving the body;'s ability to absorb nutrients. Pineapple is available fresh, frozen, dried, and canned. Many studies suggest frozen fruit has as much, if not more, nutritional value as fresh, though it may affect the flavor.

Kiwi

Kiwi is a great snack for anyone on the go, and it's packed with vitamins C, K, and E, fiber, and potassium. Although you can eat the peel safely, the best way to eat kiwi is to cut it in half and use a spoon to scoop out the center. Kiwi also has lots of antioxidants and anti-inflammatory properties. These fruits are small and easy to prepare, so pack one to eat at your desk at work, or add them to fruit salad.

Grapefruit

The grapefruit diet might not be as trendy as it once was, but grapefruit is still an excellent source of nutrients. A great source of vitamin C, of course, the citrus fruit also contains vitamin A, potassium, and fiber. Grapefruits also offer lycopene, which has been shown to fight cancer-causing cells and reduce the risk of developing tumors. Research shows that grapefruit improves heart health, making it a good option for those with cardiovascular issues. You can drink grapefruit juice and get many of the same health benefits, but eating half a fruit for breakfast or as a mid-afternoon snack is ideal.

Cauliflower

A cup of cauliflower can meet about 85 percent of your recommended daily intake of vitamin C. This vegetable from the brassica family is a healthy way to get vitamin B6, fiber, and potassium into your diet. A cup of cauliflower only has about 25 calories. For maximum nutrients, try raw cauliflower pieces with yogurt dip. You can also steam or boil cauliflower for a healthy side dish.

Broccoli

Broccoli is packed with nearly 135 percent of the recommended daily intake of this important nutrient in a single-cup serving. It also has lots of other healthy components, like vitamin B6, vitamin A, and plenty of fiber. Both the stems and the flowering heads are edible, and the cruciferous veggie can be served cooked or raw.

Brussels Sprouts

Brussels sprouts might not be at the top of everyone's list, but they're full of vitamin C and have fewer than 40 calories per cup. They're also bursting with potassium, vitamin B6, and vitamin A, and a healthy dose of fiber. Steam or roast Brussels sprouts for a healthy, vitamin C-filled side dish with your next meal.

Guava

Guava grows primarily in Central and South America and is not always well-known to North Americans. However, just one cup of the pretty pink fruit contains a whopping 625 percent of your recommended daily vitamin C. It includes 36 percent of recommended fiber, and 20 percent of vitamin A, too. Guava has been known to help with everything from common colds to high blood pressure.

Papaya

The papaya is another tropical fruit full of vitamins and minerals. It makes a great ingredient for smoothies, salads, and other delicious dishes, and delivers about 150 percent of daily vitamin C in every cup. That amount also has less than half a gram of total fat and just 62 calories. Papaya has a sweet, tropical taste with a very smooth consistency.

Cantaloupe

Cantaloupe is a great source of vitamin C. The melon exceeds the recommended daily value for vitamin A and contains plenty of potassium, too. Because vitamin C is very beneficial to immune system function and heart health, cantaloupe is a good choice for those at risk for cardiovascular concerns. Eating a dish of cantaloupe every day can also help fend off viruses and other illnesses by strengthening the immune system.

The Benefits of Vitamin B Supplements

CC0/mojzagrebinfo/Pixabay

Vitamin B is a crucial resource in your body, yet many people don't consume enough vitamin B with diet alone. Vitamin B vitamins are necessary for both men and women, especially older adults and those with certain medical conditions. Because vitamin B comes in many forms, it can be confusing to figure out exactly how to take for the most health benefits.

Types of Vitamin B Supplements

Vitamin B complex is a supplement that contains a combination of essential B vitamins so you don't have to take multiple pills each day. Some of the most effective vitamin brands include other vitamins as well, such as biotin, zinc, vitamin C and vitamin E. If you only want to take certain B vitamins, look for individual B1, B2, B3, B5, B6 and B12 supplements. If you're pregnant or obese, you need more of these vitamins, but it's good to check with your doctor for specific requirements.

Kidney Health

B Complex is one of the best vitamins for kidney health because each vitamin it contains has an important job. Vitamins B6, B12 and folic acid help prevent anemia, and the other B vitamins, such as riboflavin, thiamine and niacin, turn the food you eat into energy. If you have kidney disease, your vitamin requirements are different than someone who doesn't have it. Vitamin B6 works to make protein and red blood cells, vitamin B12 makes red blood cells and folate maintains nerve cells and assists in making new cells.

Anxiety and Depression

Vitamin B complex vitamins help with depression and anxiety. It's believed that when you're not getting enough B vitamins in your diet, it causes an imbalance in the brain neurotransmitters that create a signal to your brain, leading to depression. Vitamins B3 and B6 added with some folic acid can help improve your mood and reduce anxiety. You can visit your local natural vitamin shop to see what they have, but if you have questions, you should speak to a physician first or do some research to make sure you're taking the right supplements.

Other Conditions

Trials using vitamins B2, B9 and B12 have shown to benefit conditions such as rheumatoid arthritis and osteoarthritis. The reason these B vitamins are the best vitamins for arthritis is because they help reduce inflammation and improve joint mobility. Vitamin B12 is one of the best vitamins for fibromyalgia because low levels of the vitamin in your body can increase symptoms, making your pain and discomfort worse and causing muscle weakness, pins and needles, and unexplained aches and pains. B vitamins are some of the best vitamins to help tinnitus, or ringing in the ear. Many patients who have chronic ringing in their ears are deficient in B12. B vitamins are also the best vitamins for older men and heart health.

What to Buy

What to buy depends on what your body needs. It's helpful to determine your vitamin requirements based on age and sex before increasing your vitamin intake with your diet. Take time to learn about the top 10 vitamin brands and search vitamin company ratings to find something that works best for you. Vitamin E is good as an antioxidant, which protects the cells, so it's another vitamin that is worth considering. Vitamin G is good for improving healing capabilities and reducing inflammation. Vitamin D3 is used for treating and preventing bone disorders by assisting the body in absorbing calcium.

6 Foods With More Vitamin C Than an Orange

There are more ways than one to get a boost of vitamin C!

When it comes to getting enough vitamin C, oranges have reigned supreme as the go-to source. And with 70 mg of vitamin C in one medium-sized navel orange, one serving is about all you need to meet you daily dose (the Daily Value for vitamin C is 75 mg for women and 90 mg for men). Vitamin C is important for collagen synthesis, helps keep our immune system healthy, fights free radicals in your body and boosts iron absorption for vegetarians and vegans. Luckily, most of us get enough vitamin C daily and aren't at risk for a vitamin C deficiency. But when you're looking for other ways to get this essential nutrient in your diet, here are six foods that have more vitamin C than an orange.

Broccoli

broccoli and mushrooms on a stone tray

When people think of vitamin C, the first thing that (probably) comes to mind is citrus fruit. So, it's surprising to hear that some veggies have *even* more vitamin C than an orange—but it's true! One cup of chopped broccoli has 81 mg of vitamin C. And if you're looking for delicious ways to enjoy this veggie, try this foolproof Sautéed Broccoli with Peanut Sauce that even the pickiest eaters will love.

Kiwi

Citrus fruit, step aside. There are plenty of other fruits that probably aren't on your radar that are packed with tons of vitamin C. A single serving—or two kiwis—provides 137 mg of vitamin C. With almost double the amount of vitamin C than an orange, you'll want to be snacking on Chocolate-Pistachio Kiwi or Strawberry-Kiwi Cheesecake Toast as soon as possible.

Bell Peppers

Spanakopita Stuffed Peppers

Whether you're dealing with the red, yellow or green variety, bell peppers have more than enough vitamin C to meet your daily needs. A medium-sized red bell pepper has 152 mg, a medium-sized green bell pepper has 96 mg and a medium-sized yellow bell pepper has 218 mg. But if you can't stomach biting into a bell pepper like an apple (we don't blame you) try slicing them and dipping them into hummus or using them for this Roasted Bell Pepper Salad with Mozzarella & Basil.

Guava

This often overlooked fruit is surprisingly nutritious! With only 37 calories, 8 grams of carbs and 3 grams of fiber per fruit, you may want to consider adding this fruit to your regular rotation. Not to mention, a single fruit has 126 mg of vitamin C. Be sure to eat the rind, as that's where much of the vitamin C lives.

Pineapple

6774310.jpg

Papaya

Another overlooked tropical fruit, papaya is very similar in texture to mango, and a one-cup serving has 88 mg of vitamin C. Try it with some fresh squeezed lime juice or in a recipe, like this Shredded Pork and Fruit Relish or Glazed Tropical Fruit Pie.

Taking Too Much Vitamin C

Taking Too Much Vitamin C

• Amount of Vitamin C
  • What is the recommended dose of vitamin C?
• Vitamin C Deficiency Symptoms
  • What are the symptoms of vitamin C deficiency?
• Center
  • What Happens If You Take Too Much Vitamin C? Center

Although exceeding the recommended amount of vitamin C is unlikely to be life-threatening, these are the potential side effects of taking too much vitamin C.

Taking more than the recommended amount of vitamin C, which is more than 2,000 milligrams per day, results in side effects such as:

• Nausea and vomiting
• Diarrhea
• Abdominal pain and cramps
• Heartburn
• Insomnia (sleeping disorder)
• Headache
• Fatigue
• Fever
• Kidney stones
• Hair loss
• Irritability
• Epistaxis (bleeding through the nose)
• Menstrual abnormalities
• Weight loss
• Altered mental status
• Seizures
• Muscle pain and weakness
• Bone fractures
• Drying of the mucus membranes
• Bleeding per rectum

Vitamin C is also called ascorbic acid, which is one of the essential water-soluble vitamins for the body that is naturally available in all vegetables and fruits. It is an antioxidant that is believed to prevent you from getting sick because it boosts immunity, maintains normal blood pressure, prevents inflammation and increases collagen content in the skin.

Although excess intake of vitamin C may not be life-threatening, it can cause several side effects. Because vitamin C is water-soluble, the body can easily expel it through urine and feces, and serious adverse effects of vitamin C toxicity are rare.

What is the recommended dose of vitamin C?

According to the National Institutes of Health, the recommended daily intake (RDI) of vitamin C with regard to sex and physical condition of a person is described below.

Table 1. RDA of vitamin C for healthy adults and children (in mg)

Age group	RDA
0 to 6 months*	40
7 to 12 months*	50
1 to 3 years	15
4 to 8 years	25
9 to 13 years	45
14 to 18 years (males)	75
14 to 18 years (females)	65
19 years and older (males)	90
19 years and older (females)	75
*Vitamin C requirements of infants should be met through the diet.

Table 2. RDA of vitamin C in special situations

Pregnant teens and adolescents (14 to 18 years old)	80 mg
Pregnant women (19 years old and older)	85 mg
Lactating or breastfeeding teens and adolescents (14 to 18 years old)	115 mg
Lactating or breastfeeding women (19 years old and older)	120 mg
Smokers	Additional 35 mg beyond the RDA as smoking depletes vitamin C levels in the body

Vitamin C is responsible for the absorption of dietary iron, so people with increased iron stores in the body (hemochromatosis) must reduce their intake of vitamin C. Usually, the body absorbs less than 50 percent of the ingested vitamin C, so there are fewer chances of overdosing on the vitamin. However, an overdose of vitamin C in people with hemochromatosis may lead to life-threatening tissue damage.

Since they may interact unfavorably with medicines used to treat cancer and heart diseases, a doctor's approval is required before taking any vitamin C supplements. Additionally, the development of kidney stones has been linked to vitamin C supplementation.

What are the symptoms of vitamin C deficiency?

Whenever there is a vitamin C deficiency, health professionals recommend supplements to rectify the deficiency and allow normal functioning of the body.

Symptoms of vitamin C deficiency include:

• Gum bleeding and tooth loss
• Weight gain without any obvious cause
• Swollen and painful joints
• Weak bones
• Slow healing of wounds
• Rough and bumpy skin
• Corkscrew-shaped body hair
• Bright red hair follicles
• Spoon-shaped fingernails (may have red spots or lines on them)
• Dry and damaged skin
• Bruises (easily formed)
• Anemia (due to chronic iron deficiency)
• Tiredness and low mood
• Oxidative stress and chronic inflammation
• Stone formation in the kidneys

Consumption of too many vitamin C supplements might have serious side effects. However, consumption of excess vitamin C–rich food does not develop negative effects. If a person wants to initiate vitamin supplements and has a history of adverse reactions due to vitamin C, they must consult their physician.
