The recommended daily intake for vitamin C is 90 mg for men and 75 mg for women .

Smokers are advised to consume an additional 35 mg per day, as tobacco reduces the absorption of vitamin C and increases the bodys use of the nutrient (

  • Acerola cherry: 2,740% of the RDI
  • Guava: 628% of the RDI
  • Blackcurrants: 338% of the RDI
  • Sweet red pepper: 317% of the RDI
  • Kiwifruit: 273% of the RDI
  • Lychee: 226% of the RDI
  • Lemon: 187% of the RDI
  • Orange: 160% of the RDI
  • Strawberry: 149% of the RDI
  • Papaya: 144% of the RDI
  • Broccoli: 135% of the RDI
  • Parsley: 133% of the RDI

Vitamin C rapidly breaks down when exposed to heat, so raw fruits and vegetables are better sources than cooked ones .

Since the body does not store large amounts of vitamin C, it is recommended to eat fresh fruits and vegetables every day.

Supplementing with vitamin C has not been found to be toxic, but taking more than 2,000 mg per day may cause abdominal cramps, diarrhea and nausea, as well as increase the risk of developing oxalate kidney stones in men .

Additionally, doses over 250 mg per day may interfere with tests designed to detect blood in the stool or stomach and should be discontinued two weeks before testing .

Summary Fresh fruits and vegetables are excellent sources of vitamin C and should prevent deficiency when consumed on a daily basis. Supplementing with vitamin C is not toxic but may cause unpleasant side effects at high doses.

How Much Vitamin D Do You Need

Wondering, âHow much vitamin D do I need?â The recommended dietary allowance for people in different age groups is shown below. These recommendations come from the National Academies of Sciences, Engineering, and Medicine. Based on a number of factors, however, your healthcare provider may suggest doses that are higher or lower than whatâs listedâso consider asking your provider for their recommendation. Note that the amount of vitamin D in foods and supplements is usually expressed in terms of International Units , so âIU/dayâ refers to âInternational Units per day.â

Recommended dietary allowance for vitamin D followed by the upper intake level:

Infants 0-6 months

  • 400 IU/day for adequate intake
  • Upper intake level of 1,000 IU/day

Infants 6-12 months

  • 400 IU/day for adequate intake
  • Upper intake level of 1,500 IU/day

Children 1-3 years old

  • Recommended dietary allowance of 600 IU/day
  • Upper intake level of 2,500 IU/day

Children 4-8 years old

  • Recommended dietary allowance of 600 IU/day
  • Upper intake level of 3,000 IU/day

People 9-70 years old

  • Recommended dietary allowance of 600 IU/day
  • Upper intake level of 4,000 IU/day

People over 70 years old

  • Recommended dietary allowance of 800 IU/day
  • Upper intake level of 4,000 IU/day

Women 14-50 years old who are pregnant or lactating

  • Recommended dietary allowance of 600 IU/day
  • Upper intake level of 4,000 IU/day

Depression And Other Mood Changes

Another common symptom of vitamin D deficiency is feeling depressed. Like with fatigue, this symptom is associated with a lot of other conditions. Therefore, this is only one potential cause that can easily be verified with a blood test.

One explanation for the connection between vitamin D deficiency and feelings of depression is that the vitamin is involved in a variety of brain processes. When there isn’t enough of this vitamin to fully support all of the brain’s actions, it’s possible for depression to result.

Your healthcare provider can order tests that measure your levels of 25-hydroxyvitamin D, which is the form of vitamin D that circulates in your blood.

Causes Of Vitamin D Deficiency

The daily intake of vitamin D a person needs in order for their body to function optimally, depends on factors such as age, weight, skin color and their overall health. People whose bodies require a greater intake of vitamin D are at greater risk of experiencing vitamin D deficiency.

Being an infant or an elderly person, being obese, having darker skin and/or experiencing a health condition which compromises oneâs ability to absorb vitamins properly are all factors which may increase the daily quantity of vitamin D an individual requires.

Factors which increase the likelihood of being affected by vitamin D deficiency include:

  • Living in countries where there is little sun all year round
  • Having darker skin
  • Wearing high-factor sunscreen
  • Spending the majority of oneâs time indoors
  • Malabsorption as a result of conditions such as Coeliac disease which impede the normal uptake of nutrients
  • Avoiding foods which provide a source of vitamin D such as fatty fish and dairy products
  • Being obese
  • Being elderly

The main source of vitamin D is exposure to solar UVB radiation (from sunlight. When the body is exposed to sunlight, it can manufacture vitamin D from cholesterol, a fatty substance synthesized by the liver and found in some foods. Anything that reduces a personâs access to solar UVB radiation will compromise the bodyâs ability to manufacture sufficient levels of vitamin D, therefore eventually causing vitamin D deficiency.

How Vitamin D Became So Controversial

Vitamin D: What happens when your body does not have ...

The controversies about the benefits of vitamin D reflect how science evolves, said Dr. Barry Kramer, director of the cancer prevention division at the National Cancer Institute.

Early research on the benefits of vitamin D was mostly observational large-scale, population-level studies and did not look at endpoints that are important for long-term health, like whether a high vitamin D intake reduces one’s risk for particular diseases or death.

Researchers found associations between higher levels of vitamin D intake and a range of health benefits. “But with the observational studies especially when you’re dealing with dietary supplements and diet taking supplements is also associated with many other confounding factors that predict the outcome: being wealthier, being health-conscious, having health insurance and access to the health care system, low smoking prevalence, increased physical exercise,” said Kramer.

In other words, the people who were taking these vitamins were doing many other things that might have caused them to have better health outcomes. Still, this early science encouraged people to hop on the vitamin D bandwagon.

There are also well-documented costs associated with overtesting and getting too much vitamin D: the cost to the health system for all those tests, and the potential harms from high vitamin D levels, such as kidney stones and high calcium which can cause nausea, vomiting, and loss of appetite.

Breastfeeding And Vitamin D Deficiency

it is important to ensure that a breastfeeding person maintains adequate levels of vitamin D to support the healthy growth of a newborn in the postnatal period. For most newborns, breast milk is their primary source of vitamin D. However, not all breast milk will contain sufficient levels of vitamin D to provide an infant with their recommended vitamin D intake . If the amount of vitamin D present in breast milk is not sufficient, It is possible for infants to develop vitamin D deficiency, particularly if they:

  • Lack exposure to sunlight
  • Live in weather conditions with intense cloud covering
  • Live in a highly polluted area

The American Academy of Pediatrics recommends) that a daily supplement of 400 IU should be given to all breastfeeding infants, to safeguard against vitamin D deficiency.

However, recent research indicates that if a mother takes a supplement with a sufficiently high concentration of vitamin D , her breast milk will contain high enough levels of vitamin D to provide an infant with their recommended daily intake. This removes the need to give a supplement to an infant directly.

How Can You Measure Your Vitamin D Intake In International Units

If youâre taking a vitamin D supplement, the amount of vitamin D will likely be listed on the supplement’s nutritional label, either in International Units or micrograms . Micrograms may be abbreviated as “mcg.”

Vitamin D amounts arenât always listed directly on the labels of food items. However, labels often do list the percent Daily Value , which reflects the amount of vitamin D in a serving of that food as a percentage of 800 IU.

Finally, you can also get a sense of the vitamin D content of various kinds of food by visiting the National Institutes of Health’s resource on vitamin D .

Its Very Individual How Much Sun Exposure A Person Needs Roberta Bivins

Its very individual how much sun exposure a person needs during summer, depending on the pigment in the skin to the amount of fat in the body and how quickly your body makes new bone. Its incredibly complicated, she says.

Thats why the best way to determine if you have low vitamin D is not by symptoms alone, but with a blood test arranged through your medic.

Supplement levels

Then there is the question of exactly what level of supplementation people need. Reid says theres no danger in taking over-the-counter vitamin D of less than 25 nanomols per day.

US and Canada guidelines suggest taking 15 micrograms of vitamin D supplements each day, but some believe its not enough

But with supplements offering doses as high as 62.5 micrograms available over the counter, there are concerns around the risk of excessive vitamin D levels, which can, in rare cases, cause side effects, including nausea and vomiting. In the long term, some studies suggest too much vitamin D can increase risk of cardiovascular disease, although the research isnt conclusive.

But others argue that even more vitamin D is needed.

With such conflicting results, its unsurprising that medical experts themselves are deeply divided over the benefits of widespread supplementation. Some even argue that vested interests are propping up the billion-dollar vitamin industry, with Spector calling vitamin D supplements a pseudo-vitamin for a pseudo-disease.

Determination Of Oxygen Radical Antioxidant Capacity

The oxygen radical antioxidant capacity values for ascorbic acid and calcium ascorbate were determined using the OxiSelect Oxygen Radical Antioxidant Capacity Activity Assay Kit according to the manufacturers instructions. In brief, the area under curve of each Trolox concentration was calculated using the standard curve for ORAC activity. Ascorbic acid and calcium ascorbate were calculated as the mmol Trolox equivalents by comparison against the standard curve. The ORAC values were expressed as TE/L.

Signs And Symptoms Of Vitamin C Deficiency

Vitamin C is an essential nutrient that must be consumed regularly to prevent deficiency.

While deficiency is relatively rare in developed countries due to the availability of fresh produce and the addition of vitamin C to certain foods and supplements, it still affects roughly 7% of adults in the US .

The most common risk factors for vitamin C deficiency are poor diet, alcoholism, anorexia, severe mental illness, smoking and dialysis .

While symptoms of severe vitamin C deficiency can take months to develop, there are some subtle signs to watch out for.

Here are the 15 most common signs and symptoms of vitamin C deficiency.

Youre Not Using The Right Delivery System

It could simply be the way the vitamin is deliveredi.e. is it a chewable, a gummy, or a coated capsule? Coatings keep the vitamin from dissolving as fast, which can cause irritation in your stomach. If you take a coated vitamin and are still feeling nauseous with food, check with your doctor to see if theres a different formula you can take, suggests Sonpal. If coated capsules are a problem for you, chewables or gummies could be a good alternative.

Elevated Blood Calcium Levels

One a Day Vitamins and Nausea

Vitamin D helps your body absorb calcium from the food you eat. In fact, this is one of its most important roles.

However, if your vitamin D intake is excessive, your blood calcium may reach levels that can cause unpleasant and potentially dangerous symptoms.

The symptoms of vitamin D toxicity are primarily related to hypercalcemia, which means excessively high blood calcium levels (

Hypercalcemia typically develops after people take megadoses of vitamin D for a prolonged period of time.

For example, a 2015 case study reported that an older man with dementia who received 50,000 IU of vitamin D daily for 6 months was repeatedly hospitalized with symptoms related to high calcium levels .

In the 2020 case report mentioned earlier, the woman who took an average of 130,000 IU of vitamin D per day for 20 months was also hospitalized for symptoms related to hypercalcemia .

These included nausea, vomiting, muscle weakness, and kidney injury. Her blood calcium levels were 3.23 mmol/L (

  • poor appetite

However, not all people with hypercalcemia experience the exact same symptoms.

One woman experienced nausea and weight loss after taking a supplement that was later found to contain 78 times more vitamin D than stated on the label .

Importantly, these symptoms occurred in response to extremely high doses of vitamin D3, which led to calcium levels greater than 12 mg/dL.

How To Avoid Getting Nauseous From Taking Vitamins

Here’s a recap of the best tweaks to make to your routine to avoid feeling icky after you pop your supps.

1. Switch up *when* you take them.

If you are not used to eating first thing in the morning, you can simply take your vitamins with lunch or dinner instead. Also, take vitamins with a good amount of water to help with absorption, says Arielle Levitan, MD, co-founder Vous Vitamin LLC and author of The Vitamin Solution: Two Doctors Clear the Confusion About Vitamins and Your Health. A full 8-ounce glass is ideal. It is also best to avoid taking vitamins immediately before or after exercise, which can subsequently cause nausea, so plan your daily vitamin intake accordingly.

2. Don’t take vitamins at the same time as other medications.

It may be super simple to take all of your pills at once and call it a day, but one of the easiest ways not to get nauseous after taking vitamins is by taking them without other medications or supplements.

For instance, some women don’t feel well when taking their birth control pills and multivitamins at the same time, says Debanjan Banerjee, MD, consultant at DoctorSpring and a consultant geriatric psychiatrist at the National Institute of Mental Health and Neurosciences.

A simple solution, Dr. Banerjee says, is to show your doctor both your vitamins and medications to know if they are indeed safe to be consumed together.

3. Try a different type.

4. Double check the label for any instructions.

5. Check your dosages.

One Study Estimates That Around 20% Of The Population In The Uk Has A Profound Vitamin D Deficiency

Few doubt the role that vitamin D plays in our bone health to regulate calcium and phosphate in the body, which is why those who have a vitamin D deficiency are particularly encouraged to address it. And that may be more people than you think: one study estimates that around 20% of the population in the UK has a profound vitamin D deficiency, for example.

A third of UK adults who supplement their diet with vitamins take vitamin D

But some experts say that people with healthy levels have no need of vitamin D supplements which would be most people. In other words, they argue that in healthy people, vitamin D is not, as some have hoped, a way to prevent disease.

So whats the reality?

The basics

Despite its name, vitamin D is not a vitamin. Instead, it is a hormone that promotes the absorption of calcium in the body. The challenge is that, aside from a few foods like oily fish, vitamin D is hard to find in the average diet. But in the presence of “ultraviolet B” rays, our skin can produce its own from a common cholesterol.

Vitamin D is found in only a few foods, like oily fish

There are two main types of D. The first is vitamin D3, which is found in animals including fish and is the kind the skin makes when exposed to sunlight. The second is vitamin D2, which comes from plant-based foods including mushrooms. Studies have found that D3 is more effective, and the conclusions of a 2012 meta-analysis argue that D3 is the preferred choice for supplementation.

It is also important to note that there are areas of the population that cant convert the Beta Carotene they get from food into formed Vitamin A. This is particularly apparent in those with Type II Diabetes and Hypothyroidism.

Vitamin E

Finally, Chandler Bing is Vitamin E. He has bad habits like smoking and was more flawed than the others. He struggled to find a girlfriend for ages and had periods of self-destruction.

Vitamin E is a powerful antioxidant but can go awry if its single for too long and become a pro-oxidant. It bounds around, as my lecturer once said like a drunk friend on Tinder, desperately trying to find someone to pair up with and become more stable, if not it remains a free-radical causing mayhem. Monica saved him.

Better together

Put the whole cast together, and the synergy is unbreakable. Try and separate them, make one more important than the other, and it will not work. Our body is precisely the same it has been fine-tuning this chemistry since time began.

What can you do then?

There we have it, a cautionary tale of not mega-dosing on individual vitamins. This is just a small example of the implication of taking a reductionist approach to supplementation.

Yes, give the body what is missing.

Yes, take away what it doesnt need.

But always remember it knows better, it is continually working to restore homeostasis.
