Vitamin are essential substances that our body needs for proper growth and development,they are vitamin A,B vitamin, vitamin C, vitamin D, vitamin E, and vitamin k.
We can usually get all the vitamins from the foods we eat,our body through the skin has the ability to produce vitamin D,as well make vitamin K.
Each vitamin play a special function in the body,if you have a low level of certain vitamin in the body this could lead to some serious health crisis, meanwhile some vitamins may help to prevent medical problem,for examples vitamin A, which help to prevent night blindness.
In this article we will focus on vitamin D,the source ,the function and the deficiency,to showcase how important it is in our body system.
Vitamin D is a fat soluble vitamin which can be found in few foods,it can also be produced within the body when ultraviolet Ray’s from the sun strike our skin and stimulate the production of vitamin D.
If you stay in area such as San Francisco to Philadelphia or Athens to Beijing chances are that you may not be getting enough vitamin D, because there is less sunlight in those regions,the same hold true if you don’t get outside for at least 15 minute daily workout in the sun.
It is possible to get this universal vitamin in three major ways:
- Through our skin.
- Through our dietary.
- Through vitamin supplement.
Vitamin D obtained from sun exposure, from food and from vitamin supplement is biologically inert and must go through two activation stages in the body before it can be used:
- The first occur in the liver
- The second occur in the kidney.
Vitamin D is the nutrients we take and as well as the hormones that our body make,few foods are Naturally rich in vitamin D,for this reason the biggest dietary source of vitamin D are fortified foods and vitamin supplement.
Vitamin D-rich foods include dairy products and breakfast cereals,both are fortified with vitamin D , fatty fish such as salmon and tuna,cod liver oil, sardines,milk, cheese, and butter.
Two forms of vitamin D use in supplement are :
- Vitamin D2 or pre-vitamin D.
- Vitamin D3 or cholecalciferol.
The best way to get enough vitamin D is by taking a supplement but the level in most multivitamins (400 lU) is too low,if the multivitamin you take does not have 1000 IU of vitamin D you may want to consider adding a separate vitamin D supplement especially if you are the type that don’t spend much time in the sun.
One of the area that beautify the present of vitamin D in our body system is that it help to ensure that our body absorbs and retain calcium and phosphorus,both which are critical for building strong bone.
Several studies had shown that vitamin D can reduce cancer cell growth,it also play a critical role in controlling infection,many of our body organs and tissues have receptor for this universal vitamin.
Vitamin D and the bone building function.
Vitamin D help in the absorption of calcium into our system, calcium which play a major role in the bone building process,so with the help of this great vitamin our bone has access to normal mineralisation for healthy growth and development.
Many studies have linked low vitamin D level with an increased risk of fracture among the old people and they suggested that vitamin D supplementation may prevent such fractures as long as it is taken in a high enough dose.
The Evidence to this effect comes from the analysis of 12 fracture prevention trials that includes more than 40,000 elderly people,most of whom were women,the researchers found that high intake of vitamin D supplement of about 800 IU per day help to reduce hip and non spine fracture by 20%, while lower intake of about 400 IU or less failed to offer any fracture prevention benefit.
Having enough vitamin D prevent ricket in children osteomalacia or the softening of bone in adults.
Vitamin D and the muscle strengthing function.
Vitamin D may help to increase the muscle strength by preventing hypocalcemic tetany,a condition of continue spasm of the muscle resulting from chronically low blood calcium.
Vitamin D help to prevent falls,a problem that lead to substantial disability and death in older people,here again the dosage or how it is administer matter,an analysis of many studies found that taking 700 to 1000 IU of vitamin D per day lower the risk of fall by 19% while taking 200 to 600 IU per day did not offer similar result.
Vitamin D and the preventive Heart Disease function.
Research and studies are finding vitamin D deficiency may be linked to heart disease,the health experts follow up study check the vitamin D blood in nearly 50,000 men who were healthy and then followed them for 10years, they found that men who were deficient in vitamin D were twice as likely to have a heart attack than men who have adequate level of vitamin D.
In a similar studies,it was found that low vitamin D level were associated with higher risk of Heart Failure, sudden cardiac death, stroke, cardiovascular disease and cardiovascular death
There are evidence that vitamin D play a role in controlling blood pressure and preventing artery damage.
Vitamin D and the immunity function
A recent research from University of Edinburgh in Scotland revealed that vitamin D boosts the immune system and could prevent autoimmune disease.
Past research study have already Indicated that people living in higher latitude where there is limited amount of sunlight might be more likely to develop multiple sclerosis,an autoimmune disease characterised by inflammatory attack on the central nervous system.
In this new study published by journal frontiers, it was revealed that vitamin D deficiency could indeed be connected to the onset of autoimmune disease like multiple sclerosis.
Vitamin D and the preventive multiple sclerosis function
The rate of multiple sclerosis far north or far south of the equator is pretty much higher than where there is enough sunlight, researchers suspect that chronic vitamin D deficiency may be responsible for this.
For this reason there was a study to find among white men and women, those with the highest vitamin D blood level had a 62% lower risk of developing multiple sclerosis than those with the lowest vitamin D intake.however this result were not the same among black men and women because most of them had low vitamin D levels.
Vitamin D and the preventive Type 1 Diabetes function
There are evidence that vitamin D may play a role in preventing Type 1 Diabetes,a 30 years study that followed more than 10,000 Finnish children from their birth time, the children that regularly received vitamin D supplement during infancy had a nearly 90% lower risk of developing Type 1 Diabetes than those without supplement.
- Vitamins D also enhanced the instestinal absorption of irons, magnesium, phosphate,zinc and regulation of cell growth.
Deficiency of vitamin D
Estimatedly about 1billion of people globally have inadequate level of vitamin D in their blood, this deficiency can be found among different ethnic and aged group
The widespread of vitamin D deficiency is now a issue of global concern because research study over the past decade had suggested that vitamin D plays a much greater disease fighting role than we have ever imagine
Vitamin D deficiency may increase the risk of a host of chronic diseases,such as osteoporosis, Heart Disease, some cancers,and multiple sclerosis, infectious disease such as tuberculosis and the seasonal flu.
The deficiency of vitamin D causes ricket in children,,can lead to osteopenia,a condition where bone are weaker than normal, osteoporosis and fracture in adults.
Vitamin D deficiency has been associated with increase risk of common cancers, autoimmune disease Hypertension and infectious disease.
If the case of not having enough exposure to the sun at least 800-1000 IU of vitamin D3/day maybe needed to achieve adequate level of vitamin D to confer beneficial health effect in children and adults.
The list of people who may need vitamin D
- The people with dark skin
- The people with Obesity or people who had gastric surgery.
- Breastfeeding infant.
- The old people.
- The people with certain liver condition, cystic fibrosis and Crohn’s disease.
It is clear that if vitamin D deficiency can produce many potential health problems then its correct level in the body can probably help to overcome certain serious health problems
Supplement are the ideal way to make sure we get what is needed on a regular basis.
