Examples of Vitamin Deficiency
Vitamin B12 Deficiency
Vitamin B12 is essential for many aspects of health, including the production of red blood cells and our genetic material. Deficiency of Vitamin B12 may lead to a wide range of neuropsychiatric and hematologic disorders. Smokers, people older than 65 and vegetarians are more likely to be B12 deficient. According to the Centers for Disease Control and Prevention, 3%-5% of the general population suffer vitamin b12 deficiency with up to 46% in the South Asian group living in Northern sphere. The diabetes medication Metformin, the gastrointestinal drugs also deplete Vitamin B12.
Vitamin C Deficiency
Vitamin C is the most important antioxidant in human plasma. It is essential for wound healing and facilitates recovery from burns and the absorption of iron. Severe deficiency results in scurvy, which is characterised by haemorrhages and abnormal bone and dentine formation. Low blood levels of vitamin C (“chronic scurvy”) can cause atherosclerosis. According to National Health and Nutrition Examination Survey, approximately 13% of the US population was vitamin C deficient. Smokers and the dark-skinned people have elevated risks of vitamin C deficiency.
Vitamin D3 Deficiency
Low level of Vitamin D3 has been associated with the increased risk of death from cardiovascular disease; cognitive impairment; severe asthma and cancer. Research suggests that vitamin D could play a role in the prevention and treatment of type 1 and type 2 diabetes, hypertension, glucose intolerance, and multiple sclerosis. According to Genova Diagnostics in the USA 70% of whites aged 20-49 yrs and 91% of elderlies suffer either deficiency or insufficiency of vitamin D3. This rate is even higher in the dark-skinned population.
