Avoid Excess Vitamin D

8 Signs Your Body Is Begging for Vitamin D

People taking vitamin D supplements may experience hypervitaminosis. Having too much vitamin D immediately increases your absorption of calcium and phosphorus, according to a January 2018 report in the Journal of Steroid Biochemistry and Molecular Biology. This increase creates a kidney-damaging calcium-phosphorus product. That product damages your vascular system by constricting your arteries and causing high blood pressure.

Additional symptoms of vitamin D toxicity range from heart problems to mental confusion. High levels of calcium can increase thirst and the need to urinate. They may also cause constipation.

How Do You Ensure You Have Enough Vitamin D

The recommended daily allowance of vitamin D is 600 international units for most people ages 1 to 70, according to the Food and Nutrition Board at the Institute of Medicine of the National Academies. For people over the age of 70 its 800 IU, and for infants its 400 IU.

But its not easy to get that much vitamin D through diet and sunlight alone. The average amount of the nutrient that an individual gets from food and drink rarely exceeds 288 IU per day. Even drinking milk fortified with vitamin D will get you only 100 IU per 8-ounce glass, and the same goes for most plant-milk substitutes that are fortified with vitamin D.

Thats why many people take vitamin D supplements. The Endocrine Society recommends that adults take 1,5002,000 IU per day in supplements to avoid vitamin D deficiency, and 1,000 IU per day for infants and children. Yet recommendations vary widely. Keep in mind that there can be too much of a good thing with vitamin D, which is why the FNB set an upper limit of 4,000 IU per day in supplementation for people over age 9 and 1,0003,000 IU for infants and children up to age 8, depending on age. Dosages beyond those increase the risk for death, cancer, and cardiovascular events, as well as falls and fractures in seniors.

Help Prevent Bone Diseases Such As Osteoporosis

Its clear that vitamin D aids in the absorption of calcium. Without enough vitamin D in the body, there will not be enough of calcium’s active form, the hormone calcitriol, according to the National Institutes of Health . Calcium absorption allows the body to maintain a sufficient level of that element as well as phosphate, both of which promote the growth and maintenance of healthy, strong bones.

Thats why getting enough vitamin D is critical for warding off bone diseases, such as rickets in children, osteomalacia in adults, and osteoporosis in the elderly.

Rickets is a rare disease in the United States. It is marked by soft and weak bones in children and is typically associated with developing countries, but an inadequate vitamin D level from lack of sun exposure or diet can affect children anywhere in the world, research shows. According to the Mayo Clinic, signs and symptoms of rickets include pain in the spine, pelvis, and legs, as well as delayed growth and muscle weakness.

Meanwhile, osteomalacia refers to softening of the bones due to vitamin D deficiency. Its signs include dull, aching pain in the legs, hips, pelvis, ribs, and back, though the condition often doesnt present symptoms in its early stages, the Mayo Clinic notes.

What Does Vitamin D Do For My Body

Did you know that vitamin D is actually considered a pro-hormone and not a vitamin? It is capable of producing its own vitamin D through the action of sunlight on the skin, giving it the nickname, sunshine vitamin. Vitamins are nutrients that cannot be synthesized by the body and must be acquired through the diet or supplements.

It is estimated that sun exposure on bare skin for 5-10 minutes 2-3 times per week allows the body the ability to produce sufficient vitamin D. Recent studies have suggested that up to 50% of adults and children worldwide are vitamin D deficient.

So what are some of the health benefits of vitamin D?

  • Healthy bones: Vitamin D plays an important role in the regulation of calcium and phosphorus levels in the blood, two factors that are extremely important for maintaining healthy bones. We need vitamin D to absorb calcium in the intestines and to reclaim calcium that would otherwise be excreted through the kidneys.
  • Vitamin D deficiency in children is call rickets, a disease characterized by a severely bow-legged appearance and softening of the bones.
  • Vitamin D deficiency in adults is called osteoporosis.
  • Reduces the risk of diabetes: Studies have shown that people who have the lowest vitamin D levels in their blood are at an increased risk of developing Type 2 Diabetes. In fact, studies have shown that people who have the lowest serum vitamin D levels are at an increased risk of developing Type 2 Diabetes later in life.

    Vitamin D Role In Human Body

    Pin on Nutrition and Fitness

    The term vitamin D is defined as a group of compounds that are cholesterol derivatives with a similar chemical structure. It is produced in the human body and passes through many stages of synthesis. Vitamin D affects our body through the immune, muscular, nervous, and cardiovascular systems. It is very important to maintain normal levels of vitamin D in the blood and supplement it in the case of shortfalls. The human body produces vitamin D as a response to sun exposure. A person can also boost their vitamin D intake through certain foods or supplements. Vitamin D Role is essential for several reasons, including maintaining healthy bones and teeth. It may also protect against a range of diseases and conditions, such as type 1 diabetes.

    • Vitamin D has multiple roles in the body. It assists in,
    • Promoting healthy bones and teeth.
    • Supporting immune, brain, and nervous system health.
    • Regulating insulin levels and supporting diabetes management.

    Don’t Let Your Vitamin D Absorption Slip Away

    Figuring out all the factors that can affect a person’s vitamin D levels is complicated. You can get the vitamin from food and by taking supplements .

    But vitamin D is also produced by the body in a complex process that starts when rays in the invisible ultraviolet B part of the light spectrum are absorbed by the skin. The liver, and then the kidneys, are involved in the steps that eventually result in a bioavailable form of the vitamin that the body can use.

    Here are nine factors that can influence a person’s vitamin D level:

    1. The latitude where you live. At higher latitudes, the amount of vitamin Dproducing UVB light reaching the earth’s surface goes down in the winter because of the low angle of the sun. In Boston, for example, little if any of the vitamin is produced in people’s skin tissue from November through February. Short days and clothing that covers legs and arms also limit UVB exposure.

    2. The air pollution where you live. Carbon particulates in the air from the burning of fossil fuels, wood, and other materials scatter and absorb UVB rays. Ozone absorbs UVB radiation, so holes in the ozone layer could be a pollution problem that winds up enhancing vitamin D levels.

    5. The temperature of your skin. Warm skin is a more efficient producer of vitamin D than cool skin. So, on a sunny, hot summer day, you’ll make more vitamin D than on a cool one.

    What Other Drugs Will Affect Cholecalciferol

    Certain medications can make it harder for your body to absorb vitamin D. If you take other medications, take them at least 2 hours before or 2 hours after you take cholecalciferol.

    Other drugs may affect cholecalciferol, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.

    1. It allows your intestine to absorb calcium from dietary sources,

    and

    2. It helps your bones maintain a steady amount of calcium.5

    Vitamin D and Chronic Pain by Dr. Andrea Furlan MD PhD

    In the warmer months leading up to, during and after summer, exposing yourself to gentle early morning or late afternoon sunlight is recommended.

    • As little as 68 minutes of sun exposure may be enough to produce 1,000 IU of vitamin D.
    • A daily walk or some other form of outdoor physical activity in the early morning or late afternoon, with your face, arms and hands exposed, could achieve this.
    • Between 10am and 4pm the sun is too harsh and you should use sun protection: stay in the shade, cover your arms and legs, wear sunglasses and a hat that shades your face and neck and use sunscreen

    The Takeaway On Vitamin D And Your Health

    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.

    What Happens If I Don’t Have Enough Vitamin D

    Moderate to severe vitamin D deficiency can lead to rickets in infants and children.

    Low vitamin D levels can lead to osteoporosis and increase the risk of falls and fractures if you are over 50. Osteoporosis occurs when your bones lose calcium and other minerals, making them fragile and more likely to break. Vitamin D helps the body to absorb calcium, so if you dont have enough, you can be at increased risk of developing osteoporosis.

    People with very low levels of vitamin D are the most at risk of developing health problems.

    A number of diseases have been linked to low vitamin D levels such as increased risk of death from cardiovascular disease, cognitive impairment in older adults, severe asthma in children and cancer. Research suggests that vitamin D could play a role in the prevention and treatment of a number of different conditions, including type1 and type 2 diabetes, hypertension, glucose intolerance and multiple sclerosis. However, Choosing Wisely Australia recommends that you do not need routine testing for vitamin D deficiency unless you are considered specifically at risk.

    How Vitamin D Deficiency Affects The Body

    HOW I INCREASED MY VITAMIN D ABSORPTION! EASY TO DO!

    Of the 13 essential vitamins, vitamin D might be one of the most unique.

    Its one of the few vitamins your body can produce itself. Well, almost by itself. It needs a little help from the sun hence why its often referred to as the sunshine vitamin. You can also get vitamin D through your diet.

    But when you arent making or getting enough of it, you might feel the effects of low vitamin D.

    Vitamin D deficiency has become increasingly common over the last decade or so. And this is concerning since a deficiency in vitamin D can have lasting effects on a persons health and wellness, says Dr. Donald Brown, primary care practitioner at Houston Methodist.

    Left untreated, vitamin D deficiency can lead to osteoporosis in adults, rickets in children and adverse outcomes in pregnant women. It may also be linked to heart disease, diabetes and cancer although more study is needed on the topic.

    And while a little bit of sunshine may sound like the simple answer to making sure youre getting enough vitamin D every day, be warned. Its a bit more complicated than that.
