Vitamin D is an essential nutrient with a wide range of benefits and is essential for good health. It plays a key role in bone health, mood, immunity, and more. While the human body can produce Vitamin D when exposed to sunlight, many people don’t get enough sun exposure to meet their daily needs. Fortunately, it’s easy to get Vitamin D through supplements, making it easy to ensure your body has what it needs. In this article, we’ll look at the sources, benefits, and deficiencies of Vitamin D. With the right knowledge; you’ll be able to ensure your body has what it needs to stay healthy and strong.
We know that vitamin D has an impact on a variety of body activities, including bone health. According to research, insufficient vitamin D levels may be a health risk for autoimmune illnesses. Cover up, use sunscreen, and stay indoors at the height of the sun’s rays to lower your risk of skin cancer. And, depending on where you live, it may be impossible to get adequate sun exposure all year. Therefore, the greatest ways to obtain vitamin D are through diet and supplementation.
What exactly is Vitamin D?
Vitamin D is a fat-soluble nutrient essential for good health. The skin produces it naturally when exposed to the sun’s ultraviolet B (UVB) rays. It’s also found in a few foods and can be used as a supplement. Vitamin D is important for bone health, immunity, and mood. It can also help protect against certain cancers and other diseases. Vitamin D is needed for the body to properly use calcium, which is important for healthy teeth and bones.
Vitamin D deficiency is widespread because many of us lead indoor lifestyles and don’t get enough sun exposure. Vitamin D deficiency has been linked to several health issues, including poor bone health, an increased risk of infection, and poor mental health. Getting enough Vitamin D can help protect against these health issues.
It is possible to obtain vitamin D from food and the sun.
Sources of Food
Few foods contain naturally high levels of vitamin D3. Fatty fish meat and fish liver oils are the finest sources. Egg yolks, beef liver and cheese all contain trace amounts. Certain mushrooms contain vitamin D2; moreover, some commercially produced mushrooms contain increased levels of D2 due to purposeful exposure to high levels of UV radiation. Many meals and supplements, such as milk products and grains, are vitamin D enriched.
- Fish liver oil
- Tuna fish
- Vitamin D-fortified orange juice
- Vitamin D-fortified dairy and plant milk
- Liver of beef
- The egg yolk
- Cereals fortified
When 7-dehydrocholesterol, a steroid, is broken down by UVB radiation from the sun (“tanning” rays), a chemical process takes place in the skin that produces vitamin D3. The quantity of vitamins absorbed varies greatly. The following factors reduce UVB sunlight exposure &, as a result, vitamin D absorption:
- Use sunscreen; appropriately applied sunscreen can inhibit vitamin D absorption by more than 90%.
- Wearing full-body covering clothes.
- Spending little time outside.
- Darker skin tones are caused by increased levels of the pigment melanin, which functions as a natural sunscreen.
Getting adequate vitamin D aids in the growth and development of bones and teeth and improves resistance to some illnesses. Vitamin D offers additional advantages and may help to reduce the development of multiple sclerosis (MS)
In addition to its primary benefits, evidence shows that vitamin D may help
- reduce heart disease risk
- Vitamin D has the potential to combat illness.
- lowering the chance of serious diseases
- Boosting immune system wellness.
- regulate mood and reduce depression, support weight loss
Vitamin D Deficiency
When your body doesn’t have enough Vitamin D, it’s known as Vitamin D deficiency. Vitamin D deficiency is common and can lead to several health issues. These include poor bone health, an increased risk of infection and poor mental health. Getting enough Vitamin D can help protect against these health issues. If you’re worried that you might be experiencing Vitamin D deficiency, it’s best to talk to your doctor. A doctor can test your blood to see if your levels are low. They can also recommend a treatment plan if they find that you’re deficient.
What are the signs and symptoms of a vitamin D deficiency?
Individuals suffering from vitamin D insufficiency may experience the following signs:
- fatigue, aches, and pains
- severe muscular or skeletal pain or weakness
- fractures, particularly in the pelvis, legs, and hips
Testing for Vitamin D Deficiency
If you’re worried that you might be experiencing Vitamin D deficiency, you can talk to your doctor about having your blood tested. Your doctor will test your blood to see if you have low Vitamin D levels. If you’re concerned about getting enough Vitamin D, you can have your blood tested every six months. This will allow you to monitor your levels and make sure you’re getting enough Vitamin D throughout the year.
Vitamin D deficiency may occur if a person does not consume enough vitamin D in their diet and does not spend enough time in the sun’s UV rays. People who cannot handle or do not consume milk, fish or egg, such as people who have lactose intolerance or who adopt a vegan diet, are more likely to be deficient. Other persons who are at significant risk of vitamin D insufficiency are:
- People are suffering from inflammatory bowel illness (ulcerative colitis, Crohn’s disease) or other disorders that impair fat digestion. Vitamin D is a fat-soluble vitamin dependent on the stomach’s ability to absorb dietary fat.
- Overweight people have decreased amounts of vitamin D in their blood. Vitamin D accumulates in excess fat cells but is difficult for the body to utilise when needed. It may be necessary to supplement with higher dosages of vitamin D to obtain an acceptable blood level. When obese persons lose fat, their levels of vitamin D rise.
- People who have had gastric bypass surgery usually have the upper section of their small intestine removed; that’s where vitamin D is absorbed.
Conditions caused by chronic Vitamin D deficiency :
Rickets: A disorder characterised by soft bones and skeletal abnormalities in newborns and toddlers caused by a failure of bone tissue to solidify.
Osteomalacia: A disorder in adults characterised by weak and mushy bones that can be corrected with supplements. Contrasted with osteoporosis, which causes the bones to become porous and brittle and is a permanent condition, is this.
How much vitamin D do I need?
The quantity of vitamin D you require daily is determined by your age. In international units (IU), the recommended quantities are
- Birth to 12 months: 400 IU
- Children 1-13 years: 600 IU
- Teens 14-18 years: 600 IU
- Adults 19-70 years: 600 IU
- Adults 71 years and older: 800 IU
- Pregnant and breastfeeding women: 600 IU
Can too much vitamin D be harmful?
Too much vitamin D (known as vitamin D toxicity) can be dangerous. Toxic symptoms include nausea, vomiting, lack of appetite, diarrhoea, fatigue, and loss of weight. Excess vitamin D can also be harmful to the kidneys. Too much vitamin D boosts calcium levels in the blood. Hypercalcemia (high blood calcium levels) can induce confusion, disorientation, and issues with heart rhythm. The majority of occurrences of vitamin D poisoning occur when people take too many vitamin D tablets. Vitamin D intoxication is not caused by excessive sun exposure since the body controls the quantity of this vitamin it generates.
Vitamin D is a vitamin that is necessary for optimum health and has several advantages. It is essential for bone health, mood, immunity, and other functions. The human body can manufacture Vitamin D when exposed to sunshine, but many individuals do not get enough sun exposure to satisfy their daily needs. Additionally, vitamin D can be obtained in a few foods or as a supplement. If you suspect you may be deficient in Vitamin D, consult your doctor to determine your daily dose. Your doctor can help to inform you how much Vitamin D you require depending on age, body weight, skin type, and sun exposure.
