How To Treat And Prevent Vitamin C Overdose
The single best way to prevent vitamin C overdose is to avoid taking supplements in high doses and to get the vitamin C your body needs from foods instead, especially fresh vegetables and fruits. Some of the foods richest in vitamin C include citrus fruits like oranges, leafy green vegetables, red peppers, melon, berries, kiwi, mango and sweet potatoes.
As mentioned above, vitamin C is water-soluble. What does this mean in terms of getting extra vitamin C out of your body? Do you pee out excess vitamin C?
Because vitamin C is water-soluble, its not as risky to take too much vitamin C as it is to take fat-soluble vitamins like vitamin A or D. Unmetabolized ascorbic acid is excreted in the urine.
That said, overdose of vitamin C is still possible if someone takes supplements in high doses for an extended period of time, especially if that person also consumes lots of vitamin C from his or her diet and/or fortified foods.
How long does it take to get vitamin C out of your system?
Vitamin C can stay in the body for weeks. However, excess amounts are usually urinated out in a matter of hours.
Vitamin C will stay in someones body longer if that person doesnt already have high levels or are deficient. In order to prevent vitamin C from being lost in the urine, its best to take smaller, multiple doses spread out throughout the day.
Is Vitamin C A Humectant
The bottom line. With age, skin becomes drier and less elastic, increasing the appearance of fine lines and wrinkles. Vitamin C is a powerful antioxidant that can help battle oxidative damage to the skin. Its often paired in skin care products with hyaluronic acid, a humectant that helps keep skin moisturized.
Why Do We Need Vitamin C At All
Ascorbic acid is a water-soluble vitamin found in a variety of fruits and vegetables. Often, we think of citrus fruit as the best vitamin C delivery system, but you can also get it from peppers, tomatoes, and cauliflower.
Once its in your system, the C helps your immune system function at its best and protect against damage from free radicals. Plus, ascorbic acid is needed to make collagen, that wondrous protein that helps heal wounds and keep our skin looking young and lovely .
Our bodies cant make vitamin C on their own, so its important that we get enough ascorbic acid from food or other outside sources.
Vitamin C deficiency is fairly rare in Western countries, but it can happen. If you take a long break from fresh produce , its possible to get scurvy which causes inflamed gums, skin spots, depression, and eventually death.
Its not common or likely if you have access to healthy food and produce, but its good to be mindful of your vitamin C intake all the same.

Can You Take Vitamin D If You Are Not Deficient
Although vitamin D is generally beneficial, there are potential side effects, so supplementation should be used in patients who have low vitamin D levels and who need vitamin D to a normal serum level. Before you stop taking the supplement, make sure you arent deficient in vitamin D, says rheumatologist Chad Deal, MD.
Is 2000 Iu Of Vitamin D Daily Safe
Mayo Clinic recommends that adults get at least the RDA of 600 IU. However, 1,000 to 2,000 IU per day of vitamin D from a supplement is generally safe, should help people achieve an adequate blood level of vitamin D, and may have additional health benefits.Read more

Can You Take 1000 Milligrams Of Vitamin C Daily
The short answer is yes, you can absolutely take 1,000 milligrams of vitamin C daily . And, based on reported benefits from this higher dosage, it’s probably a good idea to consider a higher potency source of C in your targeted nutrition regimen.
Not only does vitamin C have a high safety profile, but higher doses may also yield incrementally beneficial health benefits. For example, in a study published in Free Radical Biology & Medicine, researchers wanted to see if vitamin C could reduce C-reactive protein , a marker of the inflammatory response. High levels of CRP can indicate there may be some underlying health concerns increasing inflammatory actions that you may be unaware of.
For this study, a group of healthy nonsmokers was divided into groups. One group received 1,000 milligrams of vitamin C per day and the other received a placebo. After two months, participants in the vitamin C group experienced a 16.7 to 25.3% decrease in CRP levels compared to their baseline at the start of the study.*
Fascinatingly, the unique vitamin C/lipid/citrus bioflavonoid trio discussed earlier has also been shown to reduce CRP levels at 1,000 milligrams and better than other forms of vitamin C.*
Of course, it’s always best to discuss dosage recommendations with your personal health care provider, as they know your medical history and will be able to identify any contraindications.
How Much Do I Need
Vitamin C dissolves in water and is not stored in the body, so we do need a consistent supply to maintain adequate levels, says registered dietitian Jillian Greaves. The recommended daily intake is about 75 mg per day for women and 90 mg per day for men. For women, you could get more than your daily requirement by eating one kiwi and men could have half a papaya and call it a day.

Mayo Clinic Q And A: How Much Vitamin D Do I Need
DEAR MAYO CLINIC: I have heard different recommendations from different sources regarding vitamin D. One doctor told my husband that everyone living in the Northern Hemisphere should take a vitamin D supplement every day, even in the summer. What do you recommend?
ANSWER: Understanding how much vitamin D you need can be confusing because there are different recommendations about how much vitamin D adults should get. Using the recommendations that fall on the low end, many adults dont get the amount of vitamin D they should. Because few foods contain vitamin D naturally, eating foods fortified with vitamin D and taking a supplement may be beneficial.
Vitamin D is important because it helps your body sustain normal levels of calcium and phosphorus. Because it works as a key that allows your body to absorb calcium, vitamin D plays a critical role in forming and maintaining healthy bones. It also helps keep your muscles, nerves and immune system healthy.
Research suggests that consistently getting enough vitamin D can significantly lower the risk for the bone-thinning disease osteoporosis. Low vitamin D also is associated with falls, multiple sclerosis, rheumatoid arthritis, chronic pain, diabetes, high blood pressure, cardiovascular disease and some cancers. However, an association does not mean low vitamin D causes these conditions, or that taking a vitamin D supplement will adequately prevent or treat them.

Research suggests that vitamin C may help prevent heart disease and cancer.
Antioxidants like vitamin C do seem to reduce the oxidative stress associated with these diseases. This can happen when there are too many free radicals in your body.
A 2013 review found that vitamin C may help prevent stroke. This was mostly true for people who had low intake of vitamin C before treatment or were at high risk for stroke.
The review only found this benefit for vitamin C from food sources, not from supplements.
A 2013 review noted that high intake of vitamin C does seem to be associated with a lower risk of certain cancers. It also noted that intravenous vitamin C has been shown to improve outcomes for cancer patients.
Many experimental cancer therapies include using vitamin C along with other treatments, however. This makes it hard to know how much of an impact vitamin C has on its own.

Linus Pauling Institute Recommendation
Combined evidence from metabolic, pharmacokinetic, and observational studies, and from randomized controlled trials supports consuming sufficient vitamin C to achieve plasma concentrations of at least 60 mol/L. While most generally healthy young adults can achieve these plasma concentrations with daily vitamin C intake of at least 200 mg/day, some individuals may have a lower vitamin C absorptive capacity than what is currently documented. Thus, the Linus Pauling Institute recommends a vitamin C intake of 400 mg daily for adults to ensure replete tissue concentrations an amount substantially higher than the RDA yet with minimal risk of side effects.
This recommendation can be met through food if the diet includes at least several servings of vitamin C-rich fruit and vegetables as part of the daily recommended fruit and vegetable intake . Most multivitamin supplements provide at least 60 mg of vitamin C.

Vitamin C: The Evidence For Safety
The preponderance of scientific evidence, which has been thoroughly reviewed by several authors, shows consistently that vitamin C is safe at intakes of 2000 mg/d . Several hypothesized adverse effectsincluding the hypotheses of adverse effects of increased oxalate and kidney stone formation, increased uric acid concentrations, excess iron absorption, reduced vitamin B-12 concentrations, systemic conditioning , and prooxidant effectswere examined in detail and were found to have no substantive basis .
Although vitamin C supplementation may be less studied than vitamin E supplementation for the prevention for chronic disease, several clinical trials are relevant to its safety evaluation . For example, in the Roche European American Cataract Trial , the Age-Related Eye Disease Study , and the simvastatin-niacin study of Brown et al , patients who received the vitamin cocktails also ingested vitamin C at doses of 750, 500, and 1000 mg/d, respectively. A combination of 800 IU vitamin E/d and 1000 mg vitamin C/d has been reported to attenuate the beneficial effects of a combined simivastatin-niacin treatment when measured as angiographic endpoints, but it had no significant effects on the treatments clinical endpoints . The meaning of this observation with respect to the safety of vitamin E, vitamin C, or both in the presence or absence of simivastatin and niacin is not known.

A good recommendation is 2,000 IU per day for adults.
Deficiency in vitamin D has been associated with a higher risk of CVD, anumber of cancers, and autoimmune disorders like multiple sclerosis and type 1diabetes. Most of these come from observational studies, however, notcontrolled scientific studies. So there is only this association between theselower levels of circulating active vitamin D and these disorders.
Its a large leap to say that if we supplement the population thatits going change things. Its certainly not going to be the magic bulletthats going to cure any of these, but it will lower the risk. Therefore,Im a believer in a higher dose. For adults, I would recommend 2,000 IUper day. I myself take 2,000 IU per day. Given that it is going to depend onlatitude and other things, a good recommendation is 2,000 U.
For children, it is at 200 IU now, but it should be higher. Some of thosestudies show that if children obtain a higher level of vitamin D, they have alower risk of diseases like type 1 diabetes. I would probably increase that to400 IU daily and possibly higher. But Im going to be a littleconservative and say 400 IU for now.

The most concerning pro-oxidant effect happens in the presence of free transition metals. Now these metals are something all of us have in our bodies, so its impossible to avoid 100%. Ascorbic acid is one of the most researched nutrients and to date, the overwhelming consensus is that its good for you even when this is factored in.
Plus unlike dogs and cats, human are unique mammals in that we dont internally create this vitamin. We literally dont have a choice we need to get it from dietary sources.
What we do have a choice on though is how much we consume. We know how much is needed to avoid scurvy and deficiency symptoms and its the amount beyond that where the question mark remains is more necessarily better?
A recent scientific review of its antioxidant and pro-oxidant activity in oral health sums up the current mindset quite well:
The data validates the role of Vitamin C as an antioxidant under physiologic conditions exhibiting a cross over role as a pro-oxidant in pathological conditions. Further studies are required to substantiate its pro-oxidant activity to draw concrete conclusions.
While that review was specific to oral health, the scientists factored in generalized pro-oxidant vs. antioxidant research, too.

What Does Vitamin C Do
Vitamin C has many roles when it comes to promoting health, such as:
- Acting as an antioxidant, helping protect against free radical damage and slowing the effects of aging.
- Counteracting the negative effects of sun damage, cigarette smoke, air pollution and other environmental stressors.
- Supporting the immune system to protect against illnesses.
- Helping form collagen and maintain connective tissue, including the skin, bones, joints and blood vessels.
- Supporting eye health/vision and potentially reducing the risk for cataracts.
- Helping reduce the risk of certain types of cancers and cardiovascular disease.
- Facilitating absorption of iron.
Certain people can benefit from getting even higher amounts of vitamin C than the general population, including those who:
- smoke or around secondhand smoke
- people who eat a poor diet lacking vegetables and fruits
- those with medical conditions, such as severe malabsorption, cancer and kidney disease
Researchers shows that vitamin C deficiency symptoms most often affects those with severe malnourishment, drug and alcohol abusers, or those living in poverty.
What Dosage Of Vitamin C Is Too Much Anyway
