Everything You Need To Know About Vitamin D

Vitamin D

Vitamin D is an essential vitamin that you need to maintain a healthy life. It helps protect your bones from breaking, supports the immune system, and can even help prevent cancer. Vitamin D also significantly impacts how you feel every day because it regulates your mood and energy levels. How much vitamin D do you need? The answer depends on what factors affect your vitamin d. In this blog post, we will go over everything you should know about vitamin D.

What Is Vitamin D For?

Vitamin D is a vitamin that your body produces on its own when exposed to the sun. It is a fat-soluble vitamin that helps the human body absorb calcium and phosphorus. It helps maintain healthy bones, teeth, and muscle function, among many other things. As with many other vitamins, People don’t believe they’re getting enough vitamin D or putting enough into their bodies. It’s not exactly a one-size-fits-all as it varies among different people and their specific needs.

How Much Vitamin D Should You Take Daily

There are several variables to consider while determining how much Vitamin D you require each day. It’s primarily dependent on your present vitamin D level and whether it’s too little or excessive. If you are someone with vitamin d insufficiency or deficiency, you should take daily vitamin d supplements until your levels are within the normal range. When daily intake has reached a healthy level, it’s essential to continue supplementation to maintain optimal dosage of Vitamin D. Get your blood regularly tested to ensure that your daily dose is correct for you.

Here Are Some Factors That May Affect Your Vitamin D Levels:

  • Genetics – If you’re high or low in certain types of genes called VDRs, this can affect the body’s ability to process and use calcium efficiently.
  • Your age – If you’re younger or older than 18 years old.
  • Your Gender – Females are more likely to have lower daily vitamin d intake than men, especially after 50.
  • Your Skin Color – People with darker skin tones need a longer exposure time for their bodies to produce vitamin D. This also means that their daily intakes should be significantly higher since they require a lot more sun exposure. It’s harder for them to absorb enough sunlight through their skin. If you’re someone who has a light or fair complexion, daily dosage requirements will vary depending on your daily level.
  • How much exposure you get in the sun – Some days will be worse for sun exposure depending on where in the world you live.

Recommended Amounts

The Dietary Reference Intake(DRI) developed by NASEM’s expert committees includes guidance for vitamin D and other nutrients. The DRIs are a set of reference values devised for planning and evaluating nutrient intake among healthy individuals. The DRI values represent the intake at which there is no longer a requirement for that nutrient.

  • Recommended Dietary Allowance – The recommended dietary allowance is based on age and gender, which vary by sex and age group. They include adequate intakes rather than optimal or good intake levels. These nutrients have not been studied extensively in population groups beyond infancy. Adequate intakes ensure the nutritional adequacy of an average person over time without providing too much daily vitamin d to reduce the risk of toxicity. Females between 19-50 years old should get 600 IU per day, while males within this age range require only 400 IU/day due to increased muscle mass.
  • Advisory Committee on Nutritionals Requirements – Anyone who doesn’t meet daily intake level with food sources can take a vitamin D supplement to reach recommended dietary allowance.
  • Estimated Average Requirements – For everyone else who doesn’t meet their adequate intakes through diet alone, it’s essential to take a vitamin d supplement. Taking supplements is vital to have enough for good bone health and other functions. It’s also highly beneficial if you’re pregnant/planning on becoming pregnant or breastfeeding.

Vitamin D and Health

There are many vitamin d benefits for health. Vitamin D is vital to the body since it regulates the absorption of calcium and phosphorus in bones, affecting bone mineral density, thus preventing osteoporosis. It’s also important for optimal immune function as well as cardiovascular system regulation. You should try to keep your levels balanced to get all the benefits you need and stay healthy. Some potential benefits include:

Cancer Prevention

The effects of Vitamin D and cancer are still being researched and studied daily. Vitamin D may help reduce the risk of developing lung, breast, ovarian, and prostate cancers. The vitamin D receptor has been found in many cells throughout the body, including normal cells and cancerous ones. Researchers are studying how it works to see if there’s a link between low levels of vitamin d and increasing your chances of getting these cancers. There isn’t any evidence that suggests you should avoid going outside or wear sunscreen. However, exposure to UV rays increases your chance of skin cancer. Some think having enough Vitamin d can prevent that from happening altogether.

Immune Function

Vitamin D is essential for helping your immune system work properly. It can help you fight off infections, including colds and the flu.

Research indicates that taking vitamin D supplements may lessen respiratory tract symptoms in children at risk of asthma development or who have existing respiratory conditions. Vitamin d also regulates mood by controlling anxiety levels, increasing energy throughout the day because it regulates sleep patterns. Wheezing, choking, or difficulty breathing are examples of early warning signals that you need to be aware of.

Muscle Strength

Vitamin D is also involved in muscle function, and a recent study suggests that it might even help prevent falls. Vitamin d deficiency may cause your muscles to be weaker. As a result, you’ll have more trouble accomplishing basic activities like dressing yourself, getting out of bed, or climbing stairs.

Gastrointestinal Function

In addition, vitamin d plays an essential role in the digestive system, which helps with bowel movements and maintaining healthy teeth and gums. In one clinical trial, people who took high doses of vitamin D showed improved symptoms compared to those given a placebo pill. The calcium found naturally present within our bodies cannot work without this fat-soluble hormone. Because they need to be absorbed into the bone tissue, blood, and intestinal tissue, they are not suitable for direct application.

Cardiovascular Disease

Vitamin D may also help protect against heart disease. In a study published in the American Heart Journal, researchers looked at whether there was an association between vitamin d and calcium intake and coronary artery calcification. CAC is used as a marker of subclinical atherosclerosis or to assess cardiovascular risk factors like heart disease.

The results showed that those with low levels of vitamin d had about twice as much CAC compared to those who took higher amounts daily. This would suggest that people taking higher doses of aspirin are less likely to get cardiovascular diseases, such as stroke or heart attack. Because it helps keep your blood pressure down by regulating sodium levels. Plus, lower cholesterol reduces risks for developing other health problems like diabetes and obesity, among others.

Diabetes Prevention

Studies show that vitamin d can help prevent diabetes. One study found that people with higher levels of vitamin D were less likely to develop type-I diabetes. Another observational study in the Netherlands showed an inverse relationship between dietary intake, serum concentration, and risk for developing type II diabetes.

Individuals who had a low intake of foods containing vitamin D were more likely to have developed these conditions during this time frame. Vitamin D’s primary function is to regulate glucose metabolism, which allows us to control it much better than those who don’t have it. It helps regulate insulin secretion within our bodies while keeping cells sensitive to its effects. There’s also research indicating high doses may improve glycemic control among diabetic patients. Still, more studies need to be done in this area.

Bone Health

Vitamin D has been shown to help protect against bone loss and bone fractures. Low vitamin D levels have been linked to an increased risk of fractures in older people. Several studies suggest that high-dose vitamin D supplementation can prevent bone fractures if taken correctly. Vitamin D has also been shown to help maintain bone health, and it’s essential for calcium absorption.

This is important because bones are the most common site for vitamin d deficiency. Weak bones can lead to osteoporosis, the loss of bone density, which can lead to fractures. You’re more likely to develop bones like soft bones ( osteomalacia ) or brittle bones ( osteoporosis ) if your body doesn’t get enough Vitamin D. Soft bones are relatively common within this deficiency.

Vitamin D Toxicity

Intravenous fluids and medications such as corticosteroids or bisphosphonates, depending on the severity of your condition, might be administered by your doctor. Taking 60,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity. Although vitamin D is a vital vitamin for the body, excessive vitamin D can be dangerous. Vitamin d toxicity comes from taking vitamin supplements or eating foods high in vitamin d.

A vitamin D overdose causes the vitamin to build up in your body over time which is why it’s essential to know how much you need daily. If vitamin d toxicity is not treated, it can become life-threatening and even death from a heart attack or stroke. Vitamin D therapy might include stopping vitamin D intake and restricting dietary calcium. Intravenous fluids and medications such as corticosteroids or bisphosphonates, depending on the severity of your condition, might be administered by your doctor. Taking 60,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity.

Symptoms Of Vitamin D Toxicity

Some vitamin d toxicity symptoms include:

  • nausea and vomiting
  • loss of appetite, weight loss
  • headache
  • dry mouth and thirst.

Know The Dose

When vitamin D builds up in the body, it can cause changes in your blood levels. It is essential to talk to a physician about how much vitamin D you should be taking daily to make sure you avoid vitamin d toxicity. Remember that everyone has different needs depending on age, skin color, sun exposure, etc. Being aware of these factors will go a long way in knowing what dosage or amount works best for you. You can have normal healthy bones with vitamin d supplementation. Still, too much vitamin D leads to other problems, so always consult your doctor before beginning any vitamin d supplementation. The same goes for vitamin deficiency or insufficiency.

Skin Cancer

Vitamin D has several advantages for the body, but too much of it can also be harmful. Too much sun exposure or UV radiation causes skin cancer. You should avoid spending long periods in the sun without sunscreen. Sunscreen protects you from damaging UV rays that might boost your risk of Vitamin D and Calcium depletion.

Vitamin D Deficiency

Vitamin D deficiency is one of the most common vitamin deficiencies. Vitamin d is necessary for healthy bones, and lack of vitamin d can result in bone pain, muscle weakness. Suppose you’re experiencing any sort of chronic aches or pains. In that case, it’s essential to visit a doctor because you may have Vitamin D deficiency in your system, leading to calcium absorption.

Multiple sclerosis, an autoimmune disorder that affects the central nervous system, has also been associated with vitamin d deficiency. Multiple sclerosis is when the immune system attacks the myelin sheath surrounding nerve fibers. Vitamin d deficiency may cause an autoimmune response which leads to this disease. It is essential to get more vitamin d when experiencing this.

Most Common Causes Of Vitamin D Deficiency

  • Not getting enough sun exposure.
  • Certain medications such as heartburn medicine can interfere with vitamin d absorption.
  • Older adults typically don’t eat well enough to maintain good levels of vitamin D.
  • People who have darker skin types need more sun exposure.

Vitamin D Deficiency Symptoms Can Include

  • muscle weakness
  • bone pain and aches in the bones or joints
  • chronic fatigue, tiredness, etc.
  • Constipation.

Vitamin D Deficiency Risk Factors

  • Sun avoidance
  • Darker skin color
  • Lack of vitamin D in the diet (vegan, elderly)
  • Aging (lowers the ability to synthesize vitamin d from sunlight).
  • obesity/overweight status
  • Many factors can affect your vitamin d levels, including age and genetics, so knowing these risk factors before supplementation.

Who Is At Risk?

Vitamin D deficiency is more common amongst individuals who cannot tolerate or do not consume milk, eggs, and fish. Those who are lactose intolerant or who follow a vegan diet. People at increased risk of vitamin D inadequacy include Individuals with inflammatory bowel disease or other conditions affecting the body’s ability to absorb fat. Vitamin D is a fat-soluble vitamin that requires fat absorption in the intestine.

Obese individuals have lower vitamin D levels in their blood. Vitamin D is stored in fat cells, intestines, and inflammatory diseases such as Crohn’s disease and ulcerative colitis, which result in irritation in the digestive tract. Low vitamin D levels have also been linked to increased breast cancer risk in women. Vitamin D can regulate normal breast cell development and might stop breast cancer cells from developing.

How Can I Prevent Getting Vitamin D Deficiency?

There are several options for individuals to acquire more Vitamin D. The best way to prevent getting vitamin d deficiency is sun exposure. This means that people with lighter skin should spend more time in the sun because their bodies can create enough vitamin D from sunlight. Whereas those with darker skin color typically need more prolonged periods under direct sunlight and are prone to vitamin d deficiency. Always consider how much sunscreen you’re using when spending long periods outside. This can block your body’s ability to synthesize vitamin d naturally. There are methods in preventing vitamin d deficiency.

  • Spend at least 15 – 20 minutes per day in direct sunlight
  • Get tested regularly (especially children)
  • with a doctor about whether or not you’re experiencing vitamin d deficiency symptoms.
  • Make sure you eat foods with good levels of Vitamin D, such as fatty fish, mushrooms, etc.

Vitamin D supplements are also widely available and can help prevent vitamin d deficiency. However, this is not a replacement for getting outside but rather an addition to get your daily dose of sunshine! The optimal vitamin d status is between 30 – 80 ng/ml. Always consult with a medical professional before taking any dietary supplements.

Food Sources Of Vitamin D

With natural Vitamin D found in only just a few different foods, there’s still hope that you can find some sources. . The flesh of fatty fish and fish liver oils are the most significant sources. Another few foods would be egg yolks, cheese, and beef liver have trace amounts. Some mushrooms contain vitamin D2 and certain commercially sold mushrooms that have been exposed to high quantities of ultraviolet light intentionally. Vitamin D-fortified orange juice, dairy and plant milk, sardines, and fortified cereals are excellent sources. Fortified foods are the best source of vitamin D because it is difficult to get enough sun exposure, especially in the winter months.

Vitamin D Supplementation

People often take vitamin d supplements to keep their bones healthy and increase calcium absorption as well as to get sufficient vitamin d. Which is a good reason for taking dietary supplement capsules daily every day of the week or just on days you don’t get outside much in sunlight exposure. Nutritional supplements usually contain vitamin D in ergocalciferol, vitamin d2, or vitamin d3. It’s best to get your vitamin d levels checked out by a physician. If you have been diagnosed with insufficient or deficient amounts, you should immediately begin taking vitamin d supplements. It’s essential to read labels on dietary supplements and always follow recommended dosages for maximum benefit.

Vitamin D Supplements

Vitamin d supplements are not always helpful, especially where more sun exposure would have been practical instead but not enough time outside. If you’re taking dietary supplements, please ensure that your physician approves before using any type of supplementation during pregnancy! With all these things considered, it’s essential to keep yourself healthy by knowing what nutrients are needed daily from both dietary sources and dietary supplements. It’s important not to exceed 2000IU per day from dietary supplements as this could cause toxicity symptoms. More importantly, too much Vitamin d supplementation won’t help promote bone health until what little dietary calcium isn’t absorbed gets shifted through the kidneys. Dietary reference intakes will vary according to age, gender, and life-cycle status.

What Does Sunlight Have To Do With Getting Enough Vitamin D?

Vitamin D is called the “sunshine vitamin” because its created when your skin is exposed directly to solar radiation UV-B or ultraviolet radiation. The amount of vitamin D your body can generate varies depending on factors such as UVB radiation. The vitamin D created when your skin is exposed to sunlight can be stored in the body. When spending time outdoors, wear sunscreen and put on sunglasses if you’re outside for an extended period.

You don’t want to block out UVB rays because these are necessary for producing the sunshine vitamin! If you have dark skin or white skin that doesn’t burn quickly, it’s important not to stay out too long. An easy way people get vitamin d without getting enough sunshine exposure is through vitamin supplements. Doing so can take away all risks associated with direct sun exposure, such as developing cancerous melanomas, etc. Unfortunately, this supplementation isn’t always helpful, primarily where overcast conditions exist year-round.


Vitamin D is important for both humans and animals alike. It is essential to be aware of what of the risks associated with too much or too little. Health professionals suggest the best thing is to get outside for at least 20 minutes every day and make sure you meet the daily recommended intake. When it comes down to it, everyone should be aware of their needs when it comes to getting enough vitamin d in their diet. If not, consult your doctor about how much you need regularly!
