Vitamin D: What You Need To Know About Vitamin D?

Vitamin D is known as the “sunshine” vitamin since the sun is its primary source, and it plays an important role in keeping the human body healthy. It’s actually a set of prohormones that help the body absorb phosphate/phosphorous and calcium more effectively.

According to research, its primary function is to enhance calcium absorption, which is required for bone formation and remodeling (when mature bone tissue is removed and new bone tissue is formed). A deficiency of vitamin D can result in brittle, thin, or deformed bones as a result.

People who live in colder areas, further from the equator, are more likely to have lower vitamin D levels in their bodies. It is believed that about 1 billion people around the world have low vitamin D levels in their blood, which could lead to deficiency.

HOW VITAMIN D WORKS

Vitamin D Supplement

Vitamin D’s primary role in the body is to allow calcium and phosphate to be absorbed by the intestines. Even if you took the appropriate daily dose of vitamin D, your body would be insufficient in essential minerals. Vitamin D is not immediately useable once it reaches the body (through food and supplements) or when it is produced by the body (through sun exposure). Instead, it must go through two steps, known as hydroxylation reactions, before it can be activated and used in the body. Calcitriol is the name given to vitamin D after it has been transformed into a useful, active form in the body.

VIATMIN D BENEFITS

Vitamin D serves a variety of functions in the body. It helps with. Below are some vitamin D benefits you need to know about:

  • 1. Healthy bones:
  • Vitamin D aids in the management of calcium and the maintenance of phosphorus levels in the bloodstream. These elements are essential for sustaining bone health.

    Vitamin D is required for the intestines to activate and absorb calcium, as well as to reclaim calcium that would otherwise be excreted by the kidneys.

    Vitamin D deficiency in youngsters can induce rickets, which causes the bones to weaken, resulting in a severely bowlegged appearance. Similarly, osteomalacia, or bone softening, is a symptom of vitamin D deficiency in adults. Osteoporosis is a symptom of a vitamin D deficiency.

  • 2. Reduced risk of flu
  • According to a review of existing research, vitamin D appears to have a protective effect against the influenza virus in some studies. However, the researchers looked at other studies that found vitamin D had no effect on flu and flu risk.
    To confirm the protective effect of vitamin D against the flu, more research is needed.

  • 3. Healthy pregnancy
  • According to a study, pregnant women who are vitamin D deficient are more likely to develop preeclampsia and give birth prematurely. Vitamin D deficiency has also been linked to gestational diabetes and bacterial vaginosis in pregnant women, according to doctors.

  • 4. Strengthen muscles
  • Vitamin D is important for muscle strength in addition to its bone-building properties. “A lack of vitamin D in the body raises the risk of weak muscles, which increases the risk of falling.” “Vitamin D may help boost muscle strength, therefore, preventing falls, which is a common problem that leads to substantial disability and death in older adults.

  • 5. Support the immune system and fight inflammation
  • Vitamin D can also aid in the development of immunity. It can help the immune system by fighting bacteria and viruses that are harmful to the body. High latitudes and the winter season have been linked to low vitamin D levels, increased influenza, and other respiratory illnesses, as well as negative outcomes.

People who took a daily calcium and vitamin D supplement lost more weight than those who took a placebo supplement in one research. The increased calcium and vitamin D, according to the researchers, had an appetite-suppressing impact.

  • 8. Heart health
  • Because the heart is a muscle, vitamin D has been demonstrated to be a crucial nutrient in sustaining heart health in various studies. Lower vitamin D levels are linked to a 50% increased risk of heart attacks.

    Although there isn’t enough evidence to back this up, a few studies have demonstrated that vitamin D protects the heart by decreasing blood pressure and avoiding artery damage.

  • 9. Menopausal Relief
  • Vitamin D can help women going through menopause by increasing bone mineral density and so reducing osteoporosis. One of the silent menopausal symptoms is a loss of bone mass, which is only visible after a fracture.

SIDE EFFECTS OF VITAMIN D

Although there have been reports of health hazards associated with high amounts of vitamin D in the body, they are uncommon. People who are at a higher risk of toxicity as a result of a high vitamin D consumption are (in most cases) those who have other health issues such as kidney or liver disease.

Vitamin D intake for adults should not exceed 4,000 IU per day, according to healthcare authorities. Vitamin D toxicity is rare at doses below 10,000 IU per day.

Excessive vitamin D consumption can result in bone calcification and hardening of blood vessels, lung, kidney, and cardiac tissues.

Headache and nausea are two of the most typical symptoms of too much vitamin D. Too much vitamin D, on the other hand, can cause the following:

  • A decrease in appetite
  • Mouth that is dry
  • A metallic flavor
  • Vomiting
  • Constipation
  • Diarrhea

VITAMIN D RECOMMENDED DOSAGE

Vitamin D intake can be measured in micrograms (mcg) or international units (IU). A microgram of vitamin D equals 40 international units (IU).

The following are the daily vitamin D recommendations:

  • 400 IU for infants aged 0–12 months (10 mcg).
  • 600 IU for children aged 1 to 18 years (15 mcg).
  • 600 IU for Adults aged 70 and up (15 mcg).
  • 800 IU for Adults over the age of 70 (20 mcg).
  • 600 IU for pregnant or lactating women (15 mcg).

Most people can make enough vitamin D by exposing themselves to the sun for 5–10 minutes on bare skin 2–3 times per week. Vitamin D, on the other hand, degrades quickly, which means that supplies might soon run out, especially in the winter.

VITAMIN D INTERACTION

A few drugs interact with vitamin D, especially for persons who use vitamin D supplements. If you don’t take supplements, the vitamin D your body makes from sunlight and the modest amounts of the vitamin found in fortified foods won’t interact with your prescriptions. Supplemental vitamin D can increase the amount of aluminum absorbed by the body when combined with aluminum in antacids. This could be especially problematic for persons with kidney illness.
