How Much Vitamin C Is In An Orange

What Is And How Much Vitamin C Per Day – Functions, Benefits Of, Foods High In Vitamin C

While you might typically turn to oranges as your go-to Vitamin C food source, you can get this immune-supporting nutrient in other fruits and vegetables, too. For example, take a look at these Vitamin C-rich food sources:3,

  • Sweet Yellow Peppers : 137 mg
  • Guava : 126 mg
  • Kale : 80 mg
  • Kiwi : 71 mg
  • Broccoli : 51 mg
  • Brussels Sprouts : 49 mg
  • Lemons : 83 mg
  • Papaya : 87 mg
  • Strawberries : 89 mg
  • Orange : 70 mg

Tip: Did you know that excessive heat can destroy Vitamin C in food? To get as much Vitamin C from these foods as possible, eat them raw or lightly cooked. Try cooking them for shorter periods of time, preferably through steaming or microwaving, which limits the loss of nutrients in the cooking process.4

Realistically, if you eat a healthy, balanced diet with plenty of fruits and vegetables, you probably get enough Vitamin C in your daily diet. However, if you dont consume these types of foods every day, a Vitamin C supplement can be helpful.

How Much Vitamin C Per Day Should You Take

The recommended daily allowance for vitamin C is 75mg for adult females and 90mg for adult males. However, there are certain conditions and scenarios when more vitamin C is recommended.

To boost immunity – One study found that taking 1 to 2 grams of vitamin C daily while sick shortened the duration of illness. Taking a higher dose has also been shown to potentially prevent more severe infections such as pneumonia.

To support healthy skin – The RDA is typically enough to support overall skin health and collagen production. However, some studies suggest that supplementation of up to 250mg per day is best to support wound healing.

Pregnant women – Recommended intake is 85mg per day to support moms needs and the babys development.

People who smoke – Generally, its recommended to add 35mg to the RDA per day, as people who smoke are already at higher risk for infection and cell damage.

People with iron deficiency – If youre iron deficient, you may be advised to take additional vitamin C to help with iron absorption. In fact, one study found that combining 100mg of vitamin C with an iron-rich meal increased iron absorption by 67 percent.

Should I Take More Vitamin C When Im Sick

Many people pop vitamin C pills when they feel a cold coming on. Though vitamin C helps the immune system, it does very little for a cold.

A study from the Australian National University found that vitamin C supplements did not prevent colds at all. Supplementation, in a few cases, helped people get over the cold a little bit faster since about 8 percent of participants had one less day of sickness due to vitamin C.

If you want to play it safe and add more vitamin C when youre sick, its still best to do it through food. Add more citrus or greens. Even if the vitamin C doesnt make a difference, the healthy food will help you feel better.

Vitamins And Minerals For Older Adults

Vitamins help your body grow and work the way it should. There are 13 essential vitamins vitamins A, C, D, E, K, and the B vitamins .

Vitamins have different jobs to help keep the body working properly. Some vitamins help you resist infections and keep your nerves healthy, while others may help your body get energy from food or help your blood clot properly. By following the Dietary Guidelines, you will get enough of most of these vitamins from food.

Like vitamins, minerals also help your body function. Minerals are elements that our bodies need to function that can be found on the earth and in foods. Some minerals, like iodine and fluoride, are only needed in very small quantities. Others, such as calcium, magnesium, and potassium, are needed in larger amounts. As with vitamins, if you eat a varied diet, you will probably get enough of most minerals.

The best way to take vitamin C supplements is 2 – 3 times per day, with meals, depending on the dosage. Some studies suggest that adults should take 250 – 500 mg twice a day for any benefit.

Common Nutrient Deficiencies: Know The Signs

Severe vitamin C deficiency may bring about scurvy, a condition that includes symptoms ranging from fatigue to depression, joint pain, poor wound healing, and bleeding gums. Though serious, scurvy and even vitamin C deficiency are rare in developed countries. Theres one exception: Smokers have a more-than-threefold-greater risk of vitamin C deficiency, according to research published in The American Journal of Clinical Nutrition. This is likely because smoking causes greater vitamin C turnover in the body. Cigarette smoking increases free radicals in the body, which damages our cells antioxidants such as vitamin C counteract this damage but are depleted more quickly in people who smoke.

Is Taking A Huge Dose Of Vitamin C Bad For Me

Vitamin C is an important nutrient, but as the old saying goes too much of a good thing can be a bad thing.

After taking too much vitamin C, you may experience symptoms such as:

  • Diarrhea

So how much vitamin C is too much?

For adults, the daily upper limit of vitamin C is 2,000 mg. For teens, it’s 1,800 mg. For children, the upper limit depends on age, and it ranges from 400 to 1,200 mg per day.

In addition, vitamin C is water-soluble, making it hard for your body to store it with excess being secreted in your urine. So even if you’re adult and can handle the 1,000 mg in each vitamin C packet or pill, just know that your body can’t absorb more than about 400 mg. This means that most of the vitamin C in that supplement you’re taking just goes down your toilet .

All this to say, however, that getting the recommended amount of vitamin C is still a critical step in staying healthy, as this vitamin plays many important roles in your body. But, you don’t need to take a supplement to make that happen.

What Is Emergen C

I use Emergen C in my Vitamin C smoothie recipe because it makes it easy to get the right amount. They are small packets to add to water with vitamins and minerals to support your immune system.

I use the Super Orange original Emergen C, but they have several other flavors. You could make an Emergen C smoothie recipe with coconut pineapple, cranberry pomegranate, lemon lime, raspberry, pink lemonade, strawberry kiwi, or tangerine.

You would use the same immune booster smoothie recipe and use different fruits.

I like using Emergen C to support my immune system, but I’m not crazy about the taste. I’ll drink it when I need to, but this Emergen C smoothie recipe tastes better than using the packet in water.

Emergen C is for kids 14 years old and older and adults. Two of mine are over 14, so they can drink the a vitamin C smoothie recipe.

I can’t get them to drink the powder in water, but they will happily drink an Emergen C smoothie recipe.

Each Emergen C packet has 1000 mg of vitamin C, so don’t drink all of this Vitamin C smoothie recipe at once. Save half for the following day.

Emergen C is getting harder to find. I linked to Amazon, but iHerb also carries it. You can get free shipping at only $20 at iHerb.

How Can I Get The Vitamins And Minerals I Need

It is usually better to get the nutrients you need from food, rather than a pill. Thats because nutrient-dense foods contain other things that are good for you, like fiber.

Most older people can get all the nutrients they need from foods. But if you arent sure, talk with your doctor or a registered dietitian to find out if you are missing any important vitamins or minerals. He or she may recommend a vitamin or dietary supplement.

If you do need to supplement your diet, look for a supplement that contains the vitamin or mineral you need without a lot of other unnecessary ingredients. Read the label to make sure the dose is not too large. Avoid supplements with mega-doses. Too much of some vitamins and minerals can be harmful, and you might be paying for supplements you dont need. Your doctor or pharmacist can recommend brands that fit your needs.

Effects Of Mega Doses Of Vitamin C

According to a study, researchers have treated cancer patients with high dosages of vitamin C, through IVC therapy . Scientists gave cancer patients up to 100g of vitamin C a day! Thats 100,000 mg. 100 times more vitamin C than a dosage of 1,000 mg or 100,000 times the recommended daily intake of vitamin C Thats a huge dose. So, what happened to these patients?

Regarding cancer, researchers observed:

  • improvement in the quality of life,
  • improved tolerance of conventional therapy,
  • deterioration in clinical condition, in the absence of vitamin C dosage.

The side effects of mega dosages of vitamin C seem to be minimal, though. Patients experienced symptoms of Jarisch-Herxheimer reaction. This is a reaction of the body to endotoxins produced by the necrosis of harmful cells. Fever, chills, strong body odor, and pimples may be other side effects.

Dont forget that these side effects happened to cancer patients, after megadoses of vitamin C. Symptoms resolved after 2 to 3 hours, after injection with vitamin C.

On the other hand, therapy with high dosages of vitamin C may:

  • stabilize cancer,
  • have anti tumor activity in some cases,
  • help patients regain strength, even walking again
