Your body is made up of a plethora of complex systems. In order for it to operate at its maximum efficiency, there are a certain number of vitamins, nutrients, and minerals that you have to consume either in foods or through supplements. When you aren’t getting enough of something, your muscles, bones, joints, organs, and various other systems are going to suffer. You could feel a variety of symptoms from fatigue to broken bones or more serious complications, depending on what you are lacking.
Vitamin D (calciferol) is a fat-soluble vitamin that is essential for human health. It is also called a steroid vitamin because it increases the metabolism and absorption of calcium and phosphorus. Normal sunlight is actually adequate for the production of vitamin D in the skin. However, its deficiency can cause rickets in children and in adults.
The health benefits of vitamin D, also known as calciferol, include curing rickets, the treatment of osteomalacia, protection against peripheral arterial disease (PAD), slowing the progression of cancer, preventing bone fractures, and treating rachitic rosary.
Vitamin D Deficiency Symptoms
The diseases caused by vitamin D deficiency are osteomalacia and rickets. Osteomalacia is most often found in adults. The main symptoms of osteomalacia are an increase in bone fractures, a waddling walk, and muscle weakness. Rickets is a disease of the bones found in children. The symptoms of rickets include bowed hands and bowed legs. This happens due to the softening of bones.
Important Sources of Vitamin D
Sunlight is the most important source of vitamin D.rays from the sun increase the speed of production of vitamin D in the skin. Fifteen minutes of sun exposure a day is enough to complete your vitamin D requirement.
Doctors have suggested that adults that have darker skin are more likely to be vitamin D deficient because the skin doesn’t have the same capability of soaking in the sunlight exposure as those with lighter skin do.
It is found in a few foods such as mackerel, sardines, and salmon fish. Other good sources include butter, egg yolks, cod liver oil, and oily fish. Fortified milk also contains some amount of vitamin D.
People that follow a vegan diet often are vitamin D deficient because the vitamin is found mostly in animal-based foods. When you are incapable of getting vitamin D through the natural sources, there are supplements on the market that can offer the same recommended dosages.
Health Benefits of Vitamin D
Controls Phosphate & Calcium Levels
Calcium and phosphate both play essential roles in the body’s functioning. Calcium is important for the function of cells, nerves, bones, and muscles. Phosphate can be found in all the cells of the body as well. Each of these is better absorbed with the proper amount of vitamin D being present.
In the case of a deficiency of vitamin D, the body is then unable to control phosphate and calcium levels. The body may generate other hormones to encourage the release of phosphate and calcium from the bones if the levels of these minerals in the blood become very low. This results in weakening and softening of the bones. Other disorders that can arise due to problems with proper calcium and phosphate control include problems with the kidneys and .
Rickets is a skeletal disorder caused by the deficiency of vitamin D, phosphate, and calcium. It is identified by an X-ray examination of the bones in the legs. Rickets can be treated with an extra dose of oral vitamin D. During the treatment of rickets, a doctor monitors the levels of 25-OH-D in the plasma to raise it to a normal value. The abnormalities in the bones will then slowly disappear. For rickets caused by the deficiency of calcium, a supplement of extra calcium must be given along with the dose of vitamin D.
The four main components of the human bone are:
- A combination of collagen, osteoclasts (bone-removing cells), and osteoblasts (bone-manufacturing cells)
Osteomalacia means soft bones, and the disease of the same name refers to there being an issue with bones being weak or brittle.
The collagen fibers found in bones are covered by minerals. The strength of a bone depends upon the rich mineral coating over the collagen matrix. The mineral coating, if found in a significant quantity, forms a strong bone.
Osteoclasts eradicate old bone and osteoblasts manufacture the new collagen matrix. Osteomalacia takes place if the process of formation of the mineral coating does not take place correctly.
In this disease, new bones are formed without the mineral coating, which leads to softening of the bones. These types of bones may crack or bend easily. Osteomalacia is treated with an oral dose of vitamin D and direct exposure to the sun. When there isn’t an option for natural absorption of sunlight, UV lamps have often been used as a replacement treatment.
Prevents Peripheral Arterial Disease
Peripheral artery disease (PAD) occurs when there is a issue that keeps the blood from flowing properly to the limbs as it normally would. Most commonly the limbs don’t get enough blood, and as a result, there is pain felt during any movement like walking or otherwise. In severe cases, critical limb ischemia, stroke, or a heart attack can occur.
Vitamin D reduces the chance of peripheral arterial disease. It also helps the body to absorb calcium, which is essential for our bones. Children are asked to sit in the sun for a moderate amount of time for the absorption of vitamin D, in order to prevent this terrible disease.
Studies have shown that a high intake of vitamin D can slow the progression of various types of cancers and lymphoma.diseases. It helps to protect against cancers of the prostate, lung, skin, and
According to a study by the researchers of Medical Services Department, Torrent Ltd., Ahmedabad, Gujarat, India, vitamin D lowers cell proliferation and raises cell differentiation, which prevents the growth of new blood vessels, and has noteworthy anti- effects. It suggested a link between low vitamin D levels and a higher risk of cancer, with most pieces of evidence pointing towards cancer. In the Health Professionals Follow-up Study (HPFS), by Ahn J, Peters U, Albanes D, Purdue MP, Abnet CC, Chatterjee N, et al. subjects with high vitamin D were unlikely to be diagnosed with colon cancer.
In other experiments over the course of many years, it was determined that the people with the highest level of vitamin D in their systems had a 22% lower risk of cancer developing.
Prevents Disabling Fractures
Vitamin D-rich diets reduce the chances of disabling fractures. A good intake of calcium will not keep the bones strong if vitamin D is missing or lacking. This is something that is particularly important for those that are older. As we age, there is a greater risk of osteoporosis and other vitamin deficiencies that can lead to bones being broken more easily.
Additionally, balance tends to be not as good as what it was, so there is a higher chance of falling. Falls lead to breaks, so it is important to get enough vitamin D to lower the chance of something fracturing in the case of a stumble or other accident.
Treats Rachitic Rosary
Vitamin D also helps in treating rachitic rosary, which manifests in bead-like bumps seen at the joints of the ribs with their cartilages. This condition is often found in people already suffering from rickets, scurvy, or chondrodystrophy. It is a lack of calcium that causes an of the joint cartilage. Vitamin D is a natural way to treat the problem because as mentioned before, the vitamin helps the body better absorb the calcium in the way it is supposed to.
If you are worried about being vitamin D deficiency, or if you are suffering from any of the above disorders, you should talk to your medical professional. He or she can do testing to find out if your body is lacking in this essential nutrient. Then a proper recommendation can be given on how to get what you need either through food, sunlight, or supplements.
