How do calcium and vitamin D affect your health?
28 Amazing Benefits Of Vitamin D For Skin, Hair And Health
We have all learnt our A, B, C, Ds at school. These days another set of A, B, C, Ds are all the rage that are also edible! These are none other than the vitamin A, B, C, D, etc. Vitamins have umpteen benefits and we will be better off knowing a little more about them. Let’s take a look at Vitamin D benefits and how we can incorporate it into our daily routine.
What is Vitamin D?
- Vitamin D is a group of fat soluble steroids which aid in the absorption of calcium and phosphate by the intestine.
- Unlike other vitamins, we do not need to get Vitamin D from foods. The main source of Vitamin D is made by our own body with the help of sunlight. Our body can synthesize Vitamin D with adequate exposure to sun.
- People who are exposed to normal quantities of sunlight do not need Vitamin D supplements because sunlight promotes sufficient Vitamin D synthesis in the body.
There are 5 forms of Vitamin D and collectively they are known as calciferol.
- Vitamin D1 is as molecular compound of ergocalciferol with lumisterol.
- Vitamin D2 is made of ergosterol. It is produced in invertebrates, fungus, and plants in response to sunlight. Humans and other vertebrates do not produce Vitamin D2.
- Vitamin D3 is made in the skin when 7 dehyrocholestrol reacts with ultra violet light. A human requires 10 to 15 minutes of sun exposure at least twice a week on the face, arms and back without sunscreen with a greater than 3 UV index for adequate amounts of Vitamin D3 synthesis.
- Vitamin D4 is dihydroegocalciferol.
- Vitamin D5 is made up of 7 dehydositosterol.
Out of all these Vitamin D2 and D3 are most important. Although Vitamin D Is commonly called a Vitamin, it is not essentially a dietary vitamin because it can be synthesized in adequate amounts by most mammals, except cats and dogs. An organic compound can only be called Vitamin if it cannot be synthesized in sufficient portions and must be obtained from their diet. Before going into vitamin d benefits, look into its best sources and deficiency symptoms.

Sources Of Vitamin D:
There are 3 ways to get Vitamin D: food, sunlight and supplements. If you are not getting enough sunlight or you don’t spend enough time outdoors, you need to take supplements in order to cover your Vitamin D shortage. Foods which contain Vitamin D3 are:
- Salmon: 230 IU (IU = international unit=0.025 mg)
- Tuna: 200 IU
- Soy milk: 100IU
- Orange juice: 100IU
- Low fat milk: 98 IU
- Cereals: 40 IU
- Eggs: 25 IU
- Swiss cheese: 12 IU
Recommended amount:People under 70 years of age should consume 600IU of Vitamin per day and people over 70 should have 800 IU of Vitamin D per day.
Vitamin D Deficiency Symptoms:
Symptoms of Vitamin D deficiency are often vague and nonspecific and are often missed. Many people have no symptoms as such, only tiredness and general aches. This deficiency is however just as disruptive to the body as any other vitamin deficiency functions. The deficiency is more often realized in severe cases with some bone deformities.
Symptoms In Children:
- Babies with severe Vitamin deficiency can get muscle cramps, seizure and breathing difficulties. This problem is mainly due to low levels of calcium.
- Children with severe deficiency may have soft skull and leg bones. “Bow legged” or curved leg is often a symptom of Vitamin D deficiency. Children may also complain of bone pains and muscle weakness. This condition is known as rickets.
- Vitamin D deficient children often have poor growth. Height is usually affected more than weight. Affected children also face difficulty in walking.
- Children with Vitamin D deficiency may be teething late as the development of the milk teeth is affected.
- Irritability is often due to Vitamin D deficiency.
- They are also prone to respiratory issues and infections. Breathing can be affected because of weak chest muscle.
- When rickets become very severe, it can cause low level of calcium in the blood.
- Vitamin D deficiency also causes cardiomyopathy, weakness of heart muscle.
Symptoms In Adults:
- In case of severe deficiency, there might also be severe pain and also weakness.
- Muscle weakness may cause difficulty in climbing stairs or getting up from the floor or a low chair, or can lead to the person walking with a waddling pattern.
- Bones can feel painful to moderate pressure.
- People have a hairline fracture in the bone which causes tenderness and pain. Bone pain also occurs in the lower back, hips, pelvis, thighs and feet.

Causes Of Vitamin D Deficiency:
- Limited exposure to sunlight is one of the major and most common reasons for Vitamin D deficiency. Our body makes Vitamin D only if it is exposed to sunlight. Keeping yourself homebound will worsen the situation.
- The pigment melanin reduces the skin‘s ability to absorb Vitamin D. Thus darker skinned people are at risk of Vitamin D deficiency, especially older people with darker skin.
- Vitamin D deficiency also occurs if your kidneys fail to convert Vitamin D into its active form, as when people age, their kidneys are less able to convert Vitamin D into its active form.
- Obesity also affects Vitamin D absorption. Vitamin D is extracted from the blood by fat cells, altering its release into the circulation. People with a mass weight of 30 or greater often have low blood level of Vitamin D.
- Certain medical problems also hinder vitamin D absorption. Disease like Crohn’s disease, cystic fibrosis and celiac disease can affect intestine’s ability to absorb Vitamin from the food you eat.
Vitamin D plays a significant role in many of the major body functions and in absence of the right amounts can lead to what we refer to as vitamin D deficiency diseases. The probability of identifying and proceeding with vitamin D deficiency treatment is very low which why in this case prevention is better than cure.
How To Prevent Deficiency Of Vitamin D:
- All pregnant and breast feeding women should take a daily supplement of 10 micrograms of Vitamin D daily.
- Infants and young children aged 6 months to five years should take a daily supplement of Vitamin D in the form of Vitamin D drops. Breast fed infants may need to receive drops containing Vitamin D from one first month onwards if their mother has not taken Vitamin D supplements throughout.
- People aged 65 years and over and who are not exposed too much to sun should also take daily supplements containing 10 micrograms of Vitamin D.
In addition, a doctor may advise routine supplements for people with certain gut, kidney and liver disease and prescribe certain medicines for people with darker skins.

Vitamin D Benefits For Skin:
The state of your skin is a good indication of your health. Vitamin D offers not only a variety of health benefits but is also beneficial for the skin.
18. Vitamin D2 and Vitamin D3 are most beneficial for skin health.
19. Vitamin D Cream or supplements can be effective for treatment of psoriasis. 20. Vitamin D also repairs skin damage prevents infections that might be caused due to skin injuries and rejuvenate the skin.
21. One of the most well-known uses for Vitamin D in terms of skin is its treatment of psoriasis. Psoriasis symptoms include itchy and flaky skin, which can heal by the topical application of Vitamin D cream or by having prescribed Vitamin D supplements.
22. Vitamin D3 contains strong anti-inflammatory properties which make it effective for treating burns, skin injuries, skin damage and stretch marks. Thus vitamin D is mostly added in creams and lotions for its anti-inflammatory properties.
23. The anti-oxidant present in Vitamin D prevents skin damage and premature ageing of skin when taken via supplements or included in diet. Adequate skin exposure can also provide relief from these symptoms
24. Scientist are of the view that Vitamin D absorbed through limited exposure to the sun might prevent skin damage and sunburns by strengthening the skin. Opponents of this theory opine that excess of sun exposure is likely to be the main cause for most skin cancers. This issue had caused major disagreement in the scientific community. So most medical professionals advise people to limit exposure to sun and take vitamin D supplements to prevent Vitamin D deficiency.
25. Vitamin D also helps to treat eczema and is a potential saviour of rosacea sufferers. Enzymes in the skin of rosacea sufferers can cause them to produce antimicrobial peptides in an abnormal form
Vitamin D Benefits For Hair:
One of the best way to gain strong and thick hair growth is to include vitamin D rich source foods in your diet. Benefits of vitamin d for hair include the following:
26. Lack of Vitamin D can also cause hair loss. Vitamin D is found in healthy hair follicles and is generally lacking in unhealthy follicles. Vitamin reduces stress, and depression has often been linked to hair loss and various other problems. It is always good to reduce stress and live a happy life.
27. Vitamin D is also a precursor to the hair growth cycle. Vitamin D acts on the keratinocytes to initiate hair follicle cycling and stimulate hair growth. 28. Vitamin D gets converted to calcidiol when present in liver. This further gets converted by the kidneys calcitriol which is a form of active Vitamin D. This regulates cellular apoptosis which helps to regulate the cycle of the hair follicle. Technically, the cycle of hair follicle goes from:
- Anagen (growing) to
- Catagen (receding) to
- Telogen (resting) phase.
There are also Vitamin D receptors in hair follicles. Many different processes are involved in new hair formation from the follicle and Vitamin D plays a major role. Vitamin D receptors in the hair follicle have to be fed in the growing phase. This is why Vitamin D and hair deficiency go together. Studies have also shown that inhibiting Vitamin D receptors can cause hair loss. Depriving the body totally of Vitamin D will not provide necessary building blocks essential to hair growth. While Vitamin D deficiency leads to hair loss, the opposite might not be true. Overconsumption of Vitamin D will not lead to hair growth in itself. Once the hair follicle dies, it no longer goes through the cycle mentioned above. The hair follicle has to be active for Vitamin D to show any help. Thus it is important to prevent hair fall in early stages. Looking at the benefits of vitamin D we must ensure that we get adequate doses of it from sunlight and from our diet. Always consider a doctor before popping pills as overdose of vitamin D can be harmful. Take vitamin pills on your doctor’s advice and enjoy the sunshine. Stay fit, stay healthy!
