Process of vitamin D deficiency treatment   Vitamin D is not a true vitamin, as individuals with adequate exposure to sunlight do not require dietary supplementation. Vitamin D is present in our bodies in two forms Cholecalciferol and ergosterol. Vitamin D3, cholecalciferol is generated in the skin of animals when light energy is absorbed by a precursor molecule 7-dehydrocholesterol. It does not have significant biological activity until it should be metabolized within the body to the active

VitaSure: Your Vitamins and Supplements care. WHAT ARE VITAMINS AND SUPPLEMENTS? Vitamins and essential nutrients: The human body requires many essential nutrients for its proper functioning and growth. Some can be synthesized by itself and the rest have to be taken externally through food. These nutrients taken externally are called vitamins. Vitamins are organic compounds and required in limited amounts. Our body also needs an ingestion of essential nutrients like minerals, fatty acids and amino

What is Vitamin D and Vitamin D Deficiency? Vitamin D is a steroid vitamin which promotes the abdominal absorption and ingestion of Ca (calcium) and P (phosphorus). Under normal conditions of an individual's exposure to sunlight, no dietary supplements are necessary because sunlight promotes sufficient vitamin D composition in the skin. Deficiency can lead to bone deformity in children and Osteomalacia in adults. (Medical Definition of Vitamin D) Vitamin D deficiency exists when the concentration

VITAMIN K AND BLOOD CLOTTING Vitamin K is a naturally occurring vitamin, a fat-soluble vitamin. It is recognized for its role in the process of formation of blood clotting ("K" is derived from the German word "koagulation"), it is essential for the functioning of many proteins that are involved in many physiological processes (Brody T, 1999). There are two forms of naturally occurring vitamin K that are known as vitamin K1 and vitamin K2 (Figure 1). Vitamin K1 or other name is phylloquinone is synthesized

ments A. Vitamins and Minerals 1) Explain the differences between fat-soluble and water-soluble vitamins Fat soluble vitamins are A, D, E and K Fat soluble vitamins are normally stored in the body;we get these vitamins from food we eat. These vitamins dissolve in fat and are not excreted in the urine and are stored in the liver. Water soluble vitamins are C and all the B complex Water soluble vitamins are vitamins that our bodies cannot store. These vitamins can be dissolved in water when they are

Vitamins are organic compounds (contain at least one carbon atom) that meet vital functions related to metabolism and the production of hormones, neurotransmitters, blood cells or genetic material. They also possess enzymatic function accelerating chemical reactions, that without her presence would be carried out too slowly to have biological interest. Do not produce energy, but they are involved in the synthesis and maintenance of tissues. Vitamins can be divided into two groups, the water soluble

Vitamins and its Quality In the article, Catherine Price (2015) talks about the issue in these days related to the quality of dietary supplements in our diet, which are necessary to prevent many deficiencies. However, she claims that food marketers are using synthetic vitamins to sell unhealthy products. The writer also says that we were deceived because of our dependence on these vitamins that we think keep us safe. In fact, Price contends that these vitamins have come from the laboratory to the

known as Vitamin C, which many know are most commonly found in citrus fruits and some vegetables, eg; oranges, limes, lemons, bell peppers, etc.Vitamin C can be easily oxidized, when the ascorbic acid reacts to form dehydroascorbic acid. This is when two hydrogen atoms are lost, forming two ketone groups. Vitamin C is also a biological compound that is actively involved in the synthesis of collagen which is responsible for the structural protein in the hair, nail and skin growth. The vitamin C also

Top Health Benefits Vitamin B12 Top Health Benefits of Vitamin B12 Best Health Tips for Vitamin B12 Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a key role in the normal functioning of the brain and nervous system and in blood formation. It is one of eight vitamins. It is usually involved in the metabolism of human cells, in particular, affect the synthesis and regulation of DNA, but also related to fatty acid synthesis and energy generation. As the largest and most

Vitamin and minerals Explain the differences between fat-soluble and water soluble vitamins. Fat soluble vitamins These are stored in the body; they are dissolved and stored in the liver and fat tissues until you need them. They last longer in the body as you don’t need them every day. Fat soluble vitamins are: Vitamin A – Will help your immune, reproductive system it also helps your vision. It keeps the heart, lungs and the kidneys working correctly. You will get this from fish oils, liver,

order to calculate the mass of vitamin C content to determine which fruit is enriched with vitamin C that can be taken in voyages. This task was performed by titration of vitamin C in given fruits followed by standardization of iodine solution. Standardization of iodine solution was done with known amount of vitamin C tablet and using fresh fruit juice did vitamin C titration. Consequently, the class average was taken of calculated mass of fruit and mass of vitamin C content. Then, those averages

Introduction Vitamins are the organic molecules that function in a wide variety of roles within the body. The most significant function of vitamins is to serve as cofactors (co-enzymes) for enzymatic reactions. The distinguishing feature of vitamins is that they cannot be synthesized within the mammalian cells, and hence it should be taken through food supplements. The family of Vitamin B, called Vitamin B complex, plays important role in converting food into energy and helping the body metabolize

There are two types of vitamins: water soluble and fat soluble. Water soluble vitamins include vitaminsB1, B2, B3, B6, B12, vitamin C, biotin and folate. They are not stored in large amounts in the body, andany extra is lost through your urine says the Dietitians of Canada web page.Vitamin B1 helps with energy production in the body. Vitamin B2 helps with energy production in thebody. Vitamin B3 helps your body to use protein, fat and carbohydrate to make energy and helpsenzymes work right. Biotin

million people die from Vitamin A deficiency every year and around 500,000 kids turn blind because of the lack of Vitamin A. Now though, molecular biologists have added a new gene into this rice which makes it produce ‘beta carotene’ which makes the rice change colour to golden-ish. Human beings need Bata Carotene to produce Vitamin A. So by this, there would be a decrease in the rate of death due to the lack of Vitamin A right? Wrong! Most of the people who die due to Vitamin A die mainly because of

interest of Vitamin C in food contents. My family tends to have fruits and vegetables stored in the freezer. This is due to the hot climate of the country we live in. Therefore, it preserved it for a long period of time and then re-heated in order to be consumed. I began to wonder if change was happening to the Vitamin C in the fruits and vegetables once they were frozen. If so, then what? In class many lab experiments were performed such as ‘The Effect of Temperature on the Vitamin C Clock’, and
