Can You Get Enough Vitamin D In The Sun Only

How Much Vitamin D Do I Need? SURPRISING

Some people will be able to get enough vitamin D from the sun. However, it depends on where they live in the world, the time of year, the time of day, and the color of their skin.

People living near the equator get a lot of sun. In the Northern Hemisphere, a person may not be getting enough vitamin D from the sun during the winter.

The sun usually rises between 11:00 am and 3:00 pm In summer, one does not need to stay in the sun too long to make enough vitamin D.

The amount of melanin a persons skin contains affects how much vitamin D they can produce. A small amount of melanin leads to light, unprotected skin, and harmful ultraviolet radiation.

People with a lot of melanin on their skin are better protected from the sun, but it takes longer to make vitamin D. In the United States, the Centers for Disease Control and Prevention found that many Mexican, American, and non-Spanish blacks are more likely to be deficient in vitamin D.

These various factors make it difficult to recommend how much sun a person should get to make the vitamin D his body needs.

Vitamin D Council provides some examples:

  • At noon during the summer in Miami, a person with a medium skin tone will need to expose one-quarter of his or her skin to sunlight for six minutes.
  • At noon during the summer in Boston, someone with a dark skin tone will have to expose one-quarter of their skin to sunlight for two hours.

Are There Any Side Effects

How much Vitamin D do you need a day as study finds ...

There are few side effects to worry about, especially if youre only taking the recommended daily allowance. However, if you take too many supplements then something called vitamin D toxicity or hypervitaminosis D can occur. If this happens, then the main consequence is a build-up of calcium in the blood which can cause vomiting and nausea, muscle weakness and frequent urination. The toxicity would also escalate if its not dealt with and create issues in the bones and kidneys, such as the creation of calcium stones.

For this to happen, however, there would need to be a daily intake of about 60,000 IU over several months. This is 100 times higher than the recommended daily allowance of 600 to 800 IU per day so it would be quite hard to achieve by accident. Vitamin intake via the sun or foods doesnt contribute to this, as the body regulates any naturally occurring vitamins coming into the body.

How Can I Help Prevent Vitamin D Deficiency

The goals of treating and preventing the lack of vitamin D of treatment and prevention are the sameto reach and keep an adequate level of vitamin D in the body. Your healthcare provider will let you know if you need to take or keep taking vitamin D supplements. If so, they will also let you know how much you should take. You might also want to consider:

Eating more foods that contain vitamin D: See the vitamin D food sources table included in this article. Keep in mind that foods alone usually don’t meet the daily recommended levels of vitamin D.

Getting some exposure to sunshinebut not too much: Exactly how much sun exposure is needed isnt clear. 10 to 15 minutes of sun exposure two to three times a week to the face, arms, legs or back may be all that is needed to absorb a suitable amount of vitamin D. You might need more sun exposure if:

  • You are older.
  • You have a darker skin color.
  • You live in northern climates.

The use of sunscreen, and standing behind a window, prevents vitamin D from being produced in the skin. However, you should remember that too much sunshine increases the risk of skin cancer and ages the skin. That is why taking an appropriately dosed D supplement is far safer than intentionally getting routine sun exposure.

Q: Whats The Link Between Vitamin D And Heart Health

A: That isnt entirely clear. We know that low vitamin D levels are a risk factor for heart disease, but at this time, we do not know whether treating low vitamin D with supplements can prevent a heart attack. There are a number of large clinical trials studying this now. Part of the problem with finding the answer is accounting for the many factors involved in heart disease. For example, maybe people who develop heart disease are also getting less physical activity outdoors. It may not be low vitamin D levels causing the heart disease.

When Should You Take Vitamin D Morning Or Night

How much Vitamin D do you need in one day

There is limited research on whether taking vitamin D in the morning or at night is better, so its really up to personal preference. Some people find taking vitamin D in the morning or at a certain time of day useful for remembering, especially if they also take other tablets. Whereas others prefer the evenings at dinner time, with some research suggesting better absorption with a meal, but other minimal evidence would suggest that late-night consumption could affect sleep.

Konstantin Karuzin, co-founder and medical director at Bioniq, tells GoodtoKnow that ultimately aiming for breakfast could be best. Breakfast is a great time to take an immune supporting supplement, such as bioniq IMMUNE, which contains the highest-grade antioxidants and Swiss manufactured vitamins, including Zinc, Vitamin D3, K2 and C. It is blended into tiny granules that should be taken in the morning and then again in the evening for optimal absorption. This unique absorption process allows you to digest and tolerate the granules easier than vitamins that are taken singularly in pill format, which can often cause nausea and other adverse side effects. Simply mix the formula into smoothies, on top of yogurt or with juice or water.

Depression And Vitamin D Deficiency

For most people, low vitamin D levels tend to be more of a problem. Deficiency can have a number of health effects, including poor bone health, but it can also impact brain development and functioning. Low levels of vitamin D have been associated with mental health conditions including seasonal affective disorder, depression, and schizophrenia.

However, that does not mean that boosting vitamin D can always cure depression. One randomized controlled trial found insufficient evidence to support the use of vitamin D supplementation as a treatment for depression.

If you are experiencing symptoms of depression, whether or not it’s seasonal, talk to your doctor before you try to self-medicate with a supplement like vitamin D. Your doctor can assess your health and determine if vitamin D might help or if some other treatment would be more appropriate.

The Possible Link Between Vitamin D And Chronic Conditions

Generally, research on the role vitamin D may play in disease prevention and management is murky. Particularly with regard to the benefits of taking supplements, most of the studies have been observational or done on small groups . Until recent years, there has been a lack of large randomized, controlled trials, which are the gold standard for medical research because such studies point to cause-and-effect relationships between factors. The data now coming in from such trials fails to back up previous claims about the benefits of vitamin D supplementation.

But one thing is for sure: The scientific communitys interest in vitamin D clearly isnt waning. Heres what some of the latest research suggests about how the vitamin may affect certain chronic conditions.

Bone Health As mentioned, vitamin D helps in the absorption of calcium in the gut. So its no surprise that vitamin D supplements have long been recommended for preserving bone health. However, recent research has found that they dont live up to the hype. A review of more than 81 clinical trials published in November 2018 in TheLancet Diabetes and Endocrinology found that vitamin D supplements dont prevent fractures or falls, or affect bone mineral density to a degree that is clinically meaningful.

Vitamin D Supplement Safety

Your body produces vitamin D when exposed to the sun, but many people may not get enough due to a variety of factors. Because of this, people often turn to vitamin D supplements. Unfortunately, it isnt uncommon for people to overdo it.

A 2017 study published in The Journal of the American Medical Association found that between 1999 and 2014, there was an increase in the number of American adults taking daily vitamin D supplements of 1,000 IU or more. Of these, 18% exceeded 1000 IU each day and 3% took more than 4,000 IU per day, which may place them at a higher risk of experiencing some adverse effects related to excessive vitamin D.

In most cases, you can get all of the vitamin D you need naturally without supplementation through sun exposure and diet. A 15-minute walk outside each day with your extremities exposed can boost vitamin D production. .

Eating foods that are naturally high in vitamin D or are fortified with the nutrient can help. Foods you can eat to boost your vitamin D levels include:

  • Egg yolks
  • Fortified milk, yogurt, or juice
  • Cheese
  • Fatter fish such as tuna or salmon
  • Cod liver oil
