Can We Get Enough Vitamin D From The Sun Alone

Is it Safe to Take 10,000 IUs of Vitamin D3?

Although exposure to the sun is the most effective way to acquire adequate vitamin D, it comes with a cost. Furthermore, the quantity of sunlight required varies.

Individuals with darker skin, in particular those over the age of 60, produce less vitamin D in their skin.

Seasonality and geography are also important since vitamin D production varies with distance from the equator.

Vitamin D can also be formed in the skin through modest amounts of sun exposure, and it’s best to limit your time outdoors to 10 to 15 minutes, exposing your arms, legs, stomach, and back.

The Skin Cancer Organization says that you should only apply this product two to three times each week, followed by sunscreen. After then, your body will eliminate any extra vitamin D and you’ll be exposing yourself to sun damage with no added protection.

Keep in mind that the same thing that helps your body create vitamin D can also cause DNA damage, sunburn, and genetic mutations. This might lead to wrinkles appearing and raise your risk of skin cancer.

Symptoms Of Vitamin D Deficiency

It’s not easy to spot vitamin D deficiency. Some people might feel tired or get aches and pains.

But others may not have any symptoms until it’s too late, for example bowed legs or poor growth in children.

Your doctor can carry out a blood test to check your levels, but if you’re worried about your exposure to the sun or it’s winter you should start taking a supplement.

    Might Prevent Certain Types Of Cancer

    Vitamin D3 can aid in the prevention of a number of cancers. According to epidemiological studies, people who live in southern/equatorial regions and are more exposed to the sun had a decreased chance of developing certain malignancies.

    Vitamin D has been linked to cancer in numerous studies. Vitamin D aids in cell repair and regeneration, which may help to slow the development of cancerous tumors, encourage cell death that has been damaged by cancer, and reduce blood vessel formation in tumors.

    Most Finns Get The Recommended Amount Of Vitamin D

    NatureWise Vitamin D3 5,000 IU 360 Count

    Fortifying foods with vitamin D has improved the vitamin D intake of the Finnish population in the recent decades. According to the results of the FinDiet study published in 2017, 71 per cent of men and 82 per cent of women had sufficient vitamin D levels, in other words more than 50 nmol/l. The average level was 67 nmol/l in men and 77 nmol/l in women. The average daily vitamin D intake was 22 micrograms among men and 25 micrograms among women, which exceeds the current recommendations. Still, one in five gets too little vitamin D from food. If you use fortified dairy products and margarines or eat a lot of fish, its easy to get the recommended amount. However, if your diet contains none of these and you dont use vitamin D supplements, your intake remains really low, Virtanen says.

    The current Finnish recommendations for vitamin D intake were published in 2014. Virtanen says it will soon be time to assess if recent research evidence gives cause for updates. In the light of results published so far, the recommended intakes will probably not be substantially increased. However, higher recommendations could be considered for more targeted groups in the future, in relation to glucose metabolism disorders or cancer, for example.

    What Is Vitamin D3

    Vitamin D, also known as cholecalciferol, is a fat-soluble vitamin that plays a vital role in many of the body’s functions. Vitamin D is essential for calcium absorption and bone health, and it also supports immune function and cell growth.

    While our bodies can produce vitamin D from exposure to sunlight, many of us don’t get enough sun exposure to meet our needs. This is why vitamin D supplements are becoming increasingly popular.

    Vitamin D comes in two forms: D2 and D3. Vitamin D3 is the form that is most commonly found in supplements, as it is more bioavailable than vitamin D2.

    Vitamin D is having a moment in the sun. Low vitamin D levels have been linked to an increased risk of everything from heart disease, diabetes, and cancer to mood disorders and dementia in recent years, according to research. The results have not gone unnoticed. Vitamin D supplements and testing kits are becoming increasingly popular.

    Fortunately, this vitamin D increase isn’t all sunshine and lollipops. Some consumers are taking too much vitamin D supplements. Researchers examined national survey data from 1999 to 2014 and discovered a 2.8 percent rise in the number of individuals taking potentially harmful dosages of vitamin D.

    What Vitamin D Dosage Is Best

    Vitamin D is commonly known as the sunshine vitamin.

    Thats because your skin makes vitamin D when it is exposed to sunlight .

    Getting enough vitamin D is important for optimal health. It helps maintain strong and healthy bones, aids your immune system and may help protect against many harmful conditions .

    Despite its importance, roughly 42% of people in the US have a vitamin D deficiency. This number rises to a staggering 82.1% of black people and 69.2% of Hispanic people .

    There are several other groups of people that have higher vitamin D needs because of their age, where they live and certain medical conditions.

    Because there are so many factors that can affect your vitamin D level, its important to talk to your doctor if you suspect youre deficient. They can perform a blood test to see if you may benefit from upping your intake of vitamin Drich foods like salmon, fortified milk, and eggs, or taking a vitamin D supplement, according to MedlinePlus. Again, if you live in a place where winters are cool and dark, you may benefit from a supplement.

    Talking with your doctor before supplementing is even more important if youre managing a chronic condition. Not only are the benefits of vitamin D supplements unclear for certain health conditions but theres a chance the supplement may do more harm than good if youre taking a medication that interacts poorly with it.

    Another thing to keep in mind is that the Food and Drug Administration doesnt regulate supplements like it does over-the-counter medication and prescription medication. Have a conversation with your doctor about their recommended brand and dose to maintain or improve your health.

    In the view of vitamin D experts this level means you’re getting an adequate amount of vitamin D. Most people would produce this amount of vitamin D in their body if they were exposed to the sun completely naked all year at the equator. These levels are also achieved by hunter-gatherers in the bush in Africa who live a traditional way of life.

    At this vitamin D level, the body can perfectly regulate calcium absorption via the adequate formation of parathyroid hormone. Breastfeeding mothers can sufficiently pass on vitamin D to their baby through breast milk.

    Some studies suggest that these amounts of vitamin D are associated with a reduced risk of certain cancers and with better heart and circulation health. Research results also indicate that vitamin D levels in this range strengthen the immune system and support the body in fighting infection.

    If your vitamin D blood level is e.g. 25 ng/ml or higher and you want to increase them, you can take the following amount of vitamin D :

    Large Doses Can Be Harmful Even Without Symptoms Of Toxicity

    Large doses of vitamin D can be harmful, even though there may not be immediate symptoms of toxicity.

    Vitamin D is very unlikely to cause severe symptoms of toxicity right away, and symptoms may take months or years to show up.

    This is one reason why vitamin D toxicity is so difficult to detect.

    There have been reports of people taking very large doses of vitamin D for months without symptoms, yet blood tests revealed severe hypercalcemia and symptoms of kidney failure .

    The harmful effects of vitamin D are very complex. High doses of vitamin D can cause hypercalcemia without toxicity symptoms, but can also cause toxicity symptoms without hypercalcemia .

    To be safe, do not exceed the 4,000 IU upper limit without consulting a doctor or dietitian.

    Summary

    Vitamin D toxicity usually develops over time, and the harmful effects are very complex. Large doses may cause damage, despite a lack of noticeable symptoms.

    The Role Of Vitamin D Intake In Covid

    Vitamin D is also involved in immune response, and in population studies, low levels of vitamin D have been linked to an increased risk of upper respiratory tract infections. Indeed, outbreaks are more common in winter when vitamin D levels get lower. Vitamin D supplementation has been shown to prevent upper respiratory tract infections among those with significant vitamin D deficiency. For this purpose, a dosage of 20 micrograms per day has been sufficient, and higher doses have not provided any additional benefit.

    During the past year, a lot of studies have addressed the association between vitamin D status and the risk of COVID-19. In Europe, the COVID-19 situation has been among the worst in Spain and Italy where low serum levels of vitamin D are common. In these countries, theres plenty of sunshine almost all year round, but sun exposure is avoided, and as no foods are fortified with vitamin D, intake from food is low. In Finland, on the other hand, both the populations vitamin D levels and the COVID-19 situation are among the best in Europe. Of course, there are other differences between countries that can affect the situation as well, such as differences in housing density and health care capacity, Virtanen says.

    As Virtanen points out, there is yet no evidence that vitamin D supplementation could prevent you from contracting the virus. In any case its reasonable to ensure proper intake, given the role of vitamin D in the immune system.
