How To Use Vitamin D For Acne

If youre deficient in vitamin D, sitting out in the sun wont fix your acne. Doctors agree that prolonged exposure to sunshine is not the best way to get vitamin D. Exposure to the sun without using a protective sunscreen can put you at risk for skin cancer. Taking dietary supplements and consuming foods rich in vitamin D are the best ways to increase your vitamin D levels to help treat acne.

There are few foods naturally rich in vitamin D. Dairy products, like milk and cheese, are a great source of the vitamin, but have been found in

100 mcg per day of vitamin D for men and women who are not pregnant or nursing.

The most common side effect of vitamin D toxicity is a buildup of calcium in your blood, called hypercalcemia. Hypercalcelmia can cause nausea and vomiting. Taking too much vitamin D over time can result in heart arrhythmias, tissue calcification, kidney stones, and organ damage.

Vitamin D levels can also be decreased when taking corticosteroid medication.

Advice For Infants And Young Children

The Department of Health and Social Care recommends that babies from birth to 1 year of age should have a daily supplement containing 8.5 to 10 micrograms of vitamin D throughout the year if they are:

  • breastfed
  • formula-fed and are having less than 500ml of infant formula a day, as infant formula is already fortified with vitamin D

Children aged 1 to 4 years old should be given a daily supplement containing 10 micrograms of vitamin D throughout the year.

You can buy vitamin D supplements or vitamin drops containing vitamin D at most pharmacies and supermarkets.

Women and children who qualify for the Healthy Start scheme can get free supplements containing vitamin D.

See the Healthy Start website for more information.

Vitamin D is an essential nutrient that can help fortify bones and keep them strong while also potentially lowering the risk of cancer and death from cancer for some individuals. But its other effects needs to be further investigated before scientists, doctors, and everyone else can make informed decisions about supplementing or upping dietary intake of the vitamin.

Until then, take steps to get your recommended daily amount of the nutrient through food, supplements, and sunlight . If you suspect that you have a vitamin D deficiency, talk to your doctor about getting a blood test to check if your level is adequate.

Why Is A 25

Your doctor may request a 25-hydroxy vitamin D test for several different reasons. It can help them figure out whether too much or too little vitamin D is causing bone weakness or other abnormalities. It can also monitor people who are at risk for having a vitamin D deficiency.

Those who are at high risk of having low levels of vitamin D include:

  • people who dont get much exposure to the sun
  • older adults
  • babies who are breastfed only
  • people who have had gastric bypass surgery
  • people who have a disease that affects the intestines and makes it difficult for the body to absorb nutrients, such as Crohns disease

Your doctor may also want you to do a 25-hydroxy vitamin D test if theyve already diagnosed you with a vitamin D deficiency and want to see if treatment is working.

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.

Vitamin D Can Support The Immune System And Fight Inflammation

Dr. Nasrallah adds that vitamin D can also help build immunity. It can support the immune system by fighting off harmful bacteria and viruses, she says. In fact, this role in possibly preventing infections has become a critical concern during COVID-19 pandemic, as researchers are interested in its potential role in infection outcomes. There is particular interest in its role in viral infections such as influenza and coronavirus,Barry Boyd, MD, RDN, a Yale Medicine hematologist, oncologist, and nutritionist, tells Health. He points to a 2017 BMJ analysis of 25 randomized control trials comparing vitamin D supplements to placebos, which found that vitamin D reduced the risk of acute respiratory infection with either daily or weekly vitamin D supplementation, particularly in individuals who were deficient in it. Studies indicate that high latitudes and winter season are risk factors for both low vitamin D, increased influenza, and other respiratory illness and adverse outcomes, he says. We now are seeing a similar pattern with higher mortality rates in COVID-19 infections,” though more research still needs to be done to determine whether the link is causal or merely a correlation.

Vitamin D3, how much is good enough?

Vitamin D3 can assist decrease the chance of developing particular types of cancer. Epidemiological studies have shown that people who reside in southern/equatorial regions and are more exposed to the sun have a lower risk of some malignancies.

Vitamin D has been linked to cancer in numerous studies. Vitamin D aids in the repair and regeneration of cells, which might slow the growth of cancerous tumors, stimulate the death of cells that have been damaged by cancer, and decrease blood vessel formation in tumors.

Approximately one billion people worldwide are not getting enough of the highly beneficial vitamin D. We can synthesize vitamin D through our skin from exposure to sunlight, and there are small amounts of it in some foods. However, many people are still finding it difficult to obtain adequate amounts, which is why healthcare professionals recommend we take supplements to meet our nutritional needs.

In Issue 171 of The Inside Tract® newsletter, we discussed the benefits of vitamin D and how they relate to individuals with gastrointestinal diseases and disorders. We explained that individuals who have difficulty absorbing dietary fat, such as those with Crohns disease or celiac disease, may have difficulty obtaining enough vitamin D because it is fat soluble. In addition, we talked about the reduced risk of colon cancer in individuals with adequate vitamin D intake.

How Does Vitamin D3 Work

Vitamin D is a fat-soluble vitamin that can be found in only a few foods, added to others, and obtained as a dietary supplement. It’s also made naturally by the body when sunlight hit the skin and stimulate vitamin D synthesis.

Vitamin D obtained from sun exposure, food, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D , also known as calcidiol.

Calcitriol circulates as a hormone in the blood and regulates calcium and phosphate metabolism for bone formation and other physiological functions. Vitamin D sufficiency is achieved when serum 25D concentrations are 30 ng/mL .

Most vitamin D is derived from sun exposure however, the amount of sun exposure required to maintain adequate levels varies by age, skin pigmentation, season, latitude, time of day, clothing habits, and use of sunscreen.

People who have limited sun exposure need to include good sources of vitamin D in their diet or take supplements to achieve and maintain adequate serum 25D concentrations.

Elevated Blood Calcium Levels

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.

Drug Interactions Of Vitamin D2 Vs D3

Vitamin D2 and D3 each are metabolized by the liver to 25D, and therefore the potential drug interactions are similar for both forms. Vitamin D may increase the serum levels of aluminum when taken with aluminum hydroxide, a common antacid, and therefore the combination should be avoided. Thiazide diuretics, such as hydrochlorothiazide, may increase the chance of vitamin D raising calcium levels in the blood to a dangerously high level. Patients on both thiazide diuretics and vitamin D supplementation should be monitored for this effect by their healthcare provider. Some drugs may decrease the absorption and effectiveness of your vitamin D supplement. Bile-acid sequestrants, such as cholestyramine, are an example of a drug which will impair vitamin D absorption. Vitamin D and cholestyramine should not be administered at the same time.

Q: Why Is Vitamin D Important

A: Research I have done in this area has found that people with low blood levels of vitamin D have a greater risk of a heart attack, heart failure, stroke, diabetes or high blood pressure later in life. In pregnant women, low vitamin D levels are linked to pre-eclampsia, gestational diabetes and adverse pregnancy outcomes. No matter your age or stage of life, having adequate vitamin D levels is important.

How Much Vitamin D3 Should A Person Take

There is no Recommended Dietary Allowance for vitamin D. The Institute of Medicine recommends a daily intake of 600 IU of vitamin D for most adults between the ages of 19 and 70 years, including pregnant and lactating women.

The IOM set an Upper Limit of 4000 IU per day for adults to avoid the potential risk of adverse health effects associated with excessive vitamin D intake.

Pregnant and lactating women, as well as people over the age of 70 years, are advised to get more than 600 IU/day because they are at increased risk for vitamin D deficiency.

People with dark skin are at increased risk for vitamin D deficiency and may need higher intakes of vitamin D. Some researchers recommend that people with dark skin should get up to 1000-2000 IU of vitamin D per day.

A number of factors can affect how much vitamin D you need, including your age, skin color, and level of sun exposure. Talk to your healthcare provider about how much vitamin D you should take.

Is Vitamin D Or D3 More Effective

Vitamin D2 and D3 are absorbed into the bloodstream where they are metabolized by the liver into 25-hydroxyvitamin D2 and 25-hydroxyvitamin D3, otherwise collectively known as 25D or calcifediol. Calcifediol is the vitamin D complex circulating in your blood, and its levels directly reflect your bodys stores of vitamin D. Calcifediol is commonly referred to as the active form of vitamin D. When your doctor orders lab tests to check your vitamin D levels, they are measuring your calcifediol levels.

There have been several studies comparing whether supplementation with vitamin D2 or D3 produces a higher blood level of calcifediol. A study published by the National Institutes of Health was conducted in elderly, post-menopausal women who had been identified as vitamin D deficient. It compared the effects of receiving a single high dose of vitamin D2 or vitamin D3 on calcifediol levels. The study concluded that vitamin D3 produced about twice the amount of circulating calcifediol in this patient population versus that of vitamin D2.

In a separate clinical trial comparing a 10-week regimen of twice weekly 50,000 IU dosing of both vitamin D2 and vitamin D3 in demographically matched groups, vitamin D3 was also found to be superior in producing higher levels of 25D, or calcifediol.

Vitamin D3 Benefits [& WHY I NEVER GO WITHOUT IT!]

Vitamin D is a fat-soluble vitamin that is both a nutrient and acts as a hormone, explains Melissa Prest, D.C.N., R.D.N., spokesperson for the Academy of Nutrition and Dietetics. Its main function is to help the body absorb and regulate calcium and phosphorous, ensuring theyre available to strengthen bones and teeth, she adds. It also aids in the absorption of magnesium, which supports muscle and nerve function as well as energy levels.

Vitamin D boosts the immune system, too, by inhibiting the production of inflammatory cytokines, a molecule that signals inflammation, explains Heather Mangieri, R.D.N., a sports and wellness dietitian in Pittsburgh, Pennsylvania.

There are two main types of vitamin Dvitamin D2 and vitamin D3. Vitamin D2 naturally occurs in some plants, whereas vitamin D3 is found in some animals and produced by human skin via sunlight exposure. Mangieri explains that D3 is considered the more potent form of the vitamin because it has been shown to raise levels higher and for a longer period of time than D2.
