How Much Vitamin D Do I Need
Most people get as much vitamin D as they need from sunlight. If you get enough sunlight, you probably dont need to worry about extra vitamin D in your diet.
However, some people dont get enough even in a sunny country like Australia. Those most at risk are older people, especially if they live in residential care and dont get outdoors very often.
Others who might not get enough vitamin D from sunlight are those with darker skin, who cover up for cultural or religious reasons, who wear protective clothing, and who avoid the sun, for example because they have had skin cancer. Obese people, babies of mothers who dont have enough vitamin D, and people with certain medical conditions or on some medicines may also be at risk of low vitamin D.
The amount of vitamin D you need varies with your age:
- Everybody under the age of 50 needs 5 micrograms each day . A microgram is one millionth of a gram.
- People aged 51 to 70 need 10 µg/day .
- People 71 and over need 15.0 µg /day .
Why Is Vitamin D Added To Milk
- Article
If youve ever looked closely at your milks label, you may have noticed that vitamin D is added to milk. Why is vitamin D added to milk, you may ask? The story behind vitamin D and milk actually goes back to the early 20th century.
In the 1900s, rickets, a childhood bone disorder caused by not getting enough vitamin D, impacted a good number of children. In fact, around 80 percent of children in Boston had rickets at that point in history.
Around that same time, scientists began to understand the roles milks nutrients play in the body. For example, they learned that milks minerals, specifically calcium and phosphorus, were key to bone and teeth development.
In 1922, Dr. E. V. McCollum discovered that vitamin D could prevent rickets, because it was needed to help the calcium to get absorbed, so there was a scramble to get vitamin D into the diets of American children. Because vitamin D is not prevalent in many foods, fortifying milk with additional vitamin D was a natural solution, since it also contained key minerals for bone development.
Vitamin-fortified milk began to appear in the 1920s and became more common by the 1930s. Today the milk found in your supermarket is fortified with vitamin D, which has played a role in making rickets now a rare disease in the United States.

These days, milk is almost always fortified with vitamin D and the reason dates back to the 1900s. The cause of rickets is a deficiency in vitamin D or calcium. Vitamin D is synthesized in our bodies when our skin takes in the sun, and our bodies need Vitamin D to be able to absorb calcium.
Additionally, what form of vitamin D is added to milk? Cholecalciferol is a form of vitamin D of animal origin that is created from exposure to the sun, whereas ergocalciferol is of plant origin. In Canada, milk is fortified with vitamin D3. This form of vitamin D is considered to be the most effective for achieving optimal vitamin D status.
Thereof, is there a difference between whole milk and vitamin D milk?
Skim milk, 1 percent milk, 2 percent milk and whole milk all have the same amount of protein, calcium, vitamins and minerals. Vitamin D is added to all of them. The amount of fat is the only difference between them, and it’s a big difference.
How much vitamin D is in a glass of milk?
In general, an 8-ounce glass of milk contains at least 100 IUs of vitamin D, and a 6-ounce serving of yogurt contains 80 IUs, but the amount can be higher depending on how much is added. Some soy and rice milks are fortified with about the same amount, but check the label since not all contain vitamin D.

Vitamin D Fortification Strategies
Vitamin D3, administered through cod liver oil, has been used in infant nutrition in northern Europe since the 1700sat a daily dosage of a small teaspoon . This experimental dose of cod liver oil was really effective, as discovered in studies performed two centuries later the 375 IU of vitamin D3 in one teaspoon was confirmed as being the most appropriate for children .
Milk fortification with vitamin D started in the USA in the 1930s . Milk was initially fortified using two different methods: by irradiating milk with vitamin D or feeding the cows irradiated yeast . In the 1940s, a simple and valid method based on direct supplementation of vitamin D concentrate to milk was developed it is still in use today .
When considering vitamin D food fortification, it is important to evaluate whether such a public health intervention is likely to be cost-effective . Usually, micronutrient fortification is considered the most cost-effective public health intervention . With reference to vitamin D food fortification, there are only a few reports available on its cost-effectiveness. The available studies have reported that systematic vitamin D fortification may indeed be highly cost-effective . The following distribution of costs for a typical food fortification programme was determined as follows: 80% recurrent production costs, 8% marketing and education costs, 7% food control and monitoring costs, and 5% other production costs .
Contribution Of Vitamin D
For this review, 22 observational studies reported data on the contribution of vitamin D-fortified milk to vitamin D intake including 99,023 subjects . Data from the following countries were provided: United States , Canada , Finland , Ireland , Australia , Norway , Spain , Sweden , and United Kingdom . Additionally, one study provided data from both the United States and Canada. Various methods to assess vitamin D intake were used: food records , 24 h recalls , food frequency questionnaires , one-week diet history , household food diary , and both FFQ and food records .

Vitamin D In Dairy Products
Dairy cow breeding started around 5000 years ago during the late Neolithic and early Bronze Age in northern and central Europe . Milk is normally associated with cow milk however, milk from other animal species is also consumed .
Milk is a complete food providing several nutrients, specifically carbohydrates , proteins, fat, minerals, and vitamins, contributing a mean daily intake of 134 kcal, 8 g of proteins, and 7.3 g of fat to the average human diet . Water is the most represented compound in all different milks, ranging from water content lower than 50% in whale milk to water content of around 90% in donkey milk .
Milk is a natural source of calcium and vitamin D these nutrients have a synergic interaction in the human body . If the level of ionized calcium in the blood falls, the parathyroid hormone is secreted by the parathyroid gland, stimulating the conversion of vitamin D to its active form, calcitriol with a consequent decrease in vitamin D status, determined by measuring the amount of the inactive form. Vitamin D, as calcitriol, influences calcium absorption in the intestine, and lack of vitamin D is associated with a reduced absorption of dietary calcium .
How Much Vitamin D Does Milk Have
Each serving of milk fortified with vitamin D has at least 100 IU per 8 oz serving . How much is that exactly? The average healthy adult needs about 600 IU of vitamin D each day to stay healthy, and an 8 oz serving is roughly 15-20% of the daily requirement.
The best way to see how much vitamin D is in a bottle of milk is to check the nutrition label .
Here are some common brands of milk and how much vitamin D they have:
- Borden Lactose-Free 2% Reduced Fat Milk: 2.5 mcg of vitamin D

Find Out Whether Soy Almond And Other Popular Nondairy Drinks Provide Enough Of This Key Vitamin
Getting enough vitamin D from your diet can be a challenge if youre not much of a milk drinker. That’s because dairy milk, which is usually fortified with the bone-friendly nutrient, is one of the few foods that contain D in abundant amounts. But milk alternatives, such as soy milk, almond milk, coconut milk, and rice milk, may be a good option for getting vitamin D, especially now.
Many milk alternatives are fortified with vitamin D, so they contain almost as much D as cows milk. And since the Food and Drug Administration has recently increased the amount of vitamin D that can be added to both dairy milk and milk alternatives, you can now get up to 205 international units of D in an 8-ounce glass of your favorite dairy substitute. That’s almost twice as much as a milk drink could contain before the rule change.
This could really help, says Kelly Pritchett, Ph.D., R.D., an assistant professor in nutrition and exercise science at Central Washington University in Ellensburg, Wash., and a spokeswoman for the Academy of Nutrition and Dietetics. Most people dont get enough D. Fortified foods are the biggest provider in the American diet. They may be especially important if you rarely get outside in the sunshine, because your body makes D from sunlight.

Vitamin D Deficiency: Symptoms Treatment And Prevention
So how does food fit in? Back in the 1930s, people discovered that adding vitamin D to common foods like cereal and milk could improve public health. Most notably, fewer children had ricketsa condition of weak and deformed bones caused by low vitamin D intake .
Adding vitamin D to milk has other benefits, too. Milk is rich in calcium, but our bodies cant absorb it without the help of vitamin D. Adding it to milk during processing ensures were getting vitamin D and enables calcium absorption for strong bones.

Uk Scientists Want Vitamin D Added To Bread And Milk In The Middle Of The Pandemic
A group of researchers in the UK are calling for the government to encourage vitamin D supplementation in common grocery items like bread and milk, citing evidence that the nutrient can help fight the coronaviruspandemic.
Dr. Gareth Davies, an independent medical researcher, is among a group of scientists that have been investigating the role of vitamin D in COVID-19 prevention for months, and are now urging officials to take action, The Guardian reported.
As many as half of all UK residents may be deficient in vitamin D, and research suggests vitamin D deficiency could be a factor is severe COVID-19 cases.
The human body naturally produces vitamin D in response to sunlight, and it’s also found naturally in foods like fatty fish and egg yolks. Countries like the US already fortify milk and similar products with vitamin D, and residents of those nations get a substantial amount of the nutrient from fortified foods.
But many people could still benefit from supplementing, experts say. Davies has previously recommended that every adult get 4,000 IUs of vitamin D per day, 10 times the current dose recommended by health officials.

Keeping this in view, is there a difference between whole milk and vitamin D milk?
Skim milk, 1 percent milk, 2 percent milk and whole milk all have the same amount of protein, calcium, vitamins and minerals. Vitamin D is added to all of them. The amount of fat is the only difference between them, and it’s a big difference.
Subsequently, question is, how much vitamin D is in a glass of milk? In general, an 8-ounce glass of milk contains at least 100 IUs of vitamin D, and a 6-ounce serving of yogurt contains 80 IUs, but the amount can be higher depending on how much is added. Some soy and rice milks are fortified with about the same amount, but check the label since not all contain vitamin D.
Likewise, is Vitamin D milk bad for you?
Drinking whole milk may have some benefits.Research has found that among adult women, higher intake of high-fat dairy was actually linked to less weight gain than intake of low-fat dairy. Since it’s a fat-soluble vitamin, Vitamin D may be better absorbed when it’s paired with the fat in whole milk.
Which type of milk has the most vitamin D?
Whole milk contains 5 percent of your daily value of vitamin A and 24 percent of your daily value of vitamin D. After fortification, reduced-fat milk contains 9 percent of your daily value of vitamin A and 29 percent of your daily value of vitamin D.

Current Barriers To Adequate Vitamin D Intake
Many of the barriers that keep the current vitamin D fortification practices from preventing hypovitaminosis D are attributable to problems with the consumption of fluid milk. First, the amount of vitamin D added to milk may not be adequate to produce the desired health changes or even to increase circulating 25-hydroxyvitamin D concentrations. Second, milk is not uniformly consumed in the United States and Canada, and both countries have experienced pronounced declines in the overall consumption of milk in the past decade . In addition, only a few eligible milk products are fortified with vitamin D, such as a few brands of yogurt, and the concentrations in those products are variable. Furthermore, the racial/ethnicity groups at greatest risk of vitamin D insufficiency consume less milk and ready-to-eat cereal than do their white counterparts . Finally, the vitamin D contents of food are variable, which can confound analyses because of inaccurate nutrient content information.
We are indebted to Dr Youngmee K Park, retired FDA expert scientist in exposure assessment, for her valuable help in designing the determination of usual intakes of vitamin D from the NHANES III data.

What Are The Best Sources Of Vitamin D
The best source of vitamin D is sunlight. Just spending a few minutes outdoors on most days of the week should give you all the vitamin D you need.
In Australia, it is safe to go outdoors in autumn and winter with some skin uncovered, as long as the UV index is below 3. Being active while youre outside for example by walking or gardening will boost your vitamin D levels.
When the UV index is higher than 3, usually in spring and summer, most people need to protect themselves from the sun to prevent skin cancer. During these months, and if you live in parts of Australia where the UV index is above 3 all year, its usually safe to go outside without sun protection in early morning and late afternoon.
Very few foods contain much vitamin D. The best food sources of vitamin D are fatty fish like salmon, herring and mackerel, and eggs. In Australia, vitamin D is added to margarine. Some milk, soy drinks, breads and cereals may also be fortified with vitamin D.
