There are two nutritionally important forms of vitamin D in men and they are calciferol or vitamin D3 and cholecalciferol or vitamin D3. Calciferol is derived by irradiation of plant sterol, ergosterol. Cholecalciferol is naturally occurring vitamin D and is found in fish liver oil and animal fats. Cholecalciferol is also derived from exposure to sunlight or ultra violet rays of sun light which can convert 7-dehydrocholesterol in skin to vitamin D. Vitamin D is a fat soluble vitamin and is stored in fat depots.
Vitamin D: The Kidney Hormone
Vitamin D is proposed to be named as kidney hormone as it does not meet the criteria to be defined as vitamin i.e. a substance that has to be obtained by dietary means because of lack of capacity of human body to synthesize it. But vitamin D3 is not a dietary requirement in presence of adequate sunlight. Human body can synthesize adequate amount of vitamin D in the skin by exposure of as little as 5 minutes per day. No more than 5 minutes exposure to sunlight is required to synthesize enough quantity of vitamin D for one day.
Vitamin D itself is metabolically inactive unless it undergoes endogenous transformations to several active metabolites like 25, hydroxy cholecalciferol and 1, 25, dihydroxy cholecalciferol, at first in liver and than in kidney. 25, hydroxy cholecalciferol and 1, 25, dihydroxy cholecalciferol are bound to transport proteins and delivered to target tissues, bone and intestines.

Recognizing Your Addiction
Dealing with addiction is not only difficult, it can be heartbreaking. From the intensity of withdrawal to the second chance at life after rehabilitation, any recovering addict will tell you that the journey is a rocky road paved with hardship. Yet for some, the first step is the most painful and the most difficult: admitting that you have an addiction or being able to recognize the symptoms. You could have around the corner a drug rehab in northern California and still continue to live in denial or ignorance. If you struggle with drug use and its effect on your life, consider these statements and begin to help yourself.
You Have Lost Friends or Partners Over Your Drug Use
“I’m worried about you.” “You are high so much.” “Where has my friend gone?” These are all statements you might have heard from someone who was in your life but chose to leave it because of your drug use. No one wants to examine their friend or partner and see an addict, so statements like these are made out of love and concern for you. Has your relationship with drugs has become the main, or only, one in your life?
You Spend Beyond Your Means – For Drugs
Perhaps this is how one’s drug addiction begins: instead of that new cell phone or designer bag, a casual user will spend a nice bonus on cocaine. As use turns to abuse, however, addicts will find themselves sacrificing the things they need – clothes, food, rent – on drugs that they don’t. Credit card bills may pile up because they’re charging everything in order to use their cash flow to pay the dealer. Addicts are horrified when their checking accounts are wiped out faster than the blink of an eye and there’s nothing left to buy groceries. Read more…
Different Sources of Vitamin D
Vitamin D, in strict sense is not a vitamin (as per definition of vitamins are not synthesized in the body and must be supplied in the diet or supplements, but vitamin D can be synthesized in the body) and unique because it is derived both from dietary sources and sunlight.ID-10025831
Sunlight: Vitamin D is synthesized in the human body by the action of UV rays (ultra violet) on 7-dehydrocholesterol. The skin is store of large quantity of 7-dehydrocholesterol. Exposure to good quality of sunlight is very important as air pollution can filter large percentage of UV rays. Skin color if it is dark can be disadvantageous in this regard and black skin can filter up to 95 % of UV ray and hamper the formation of vitamin D from 7-dehydrocholesterol in the skin. So theoretically blacks of Africa and America can be at disadvantageous (there is advantage of black skin that black skin people rarely get skin cancer as their skin filters 95% of the harmful UV rays which are responsible for skin cancer) position as far as production of vitamin D in skin is concerned.
Food Sources of Vitamin D: Vitamin D is found only in the foods of animal origin. Liver, egg yolk, butter, cheese etc. are rich source of dietary vitamin D. fish liver oil is the richest source (though not consumed as food) of vitamin D. Foods that are artificially fortified with vitamin like milk, infant foods, cooking oils, ghee etc. are also rich source of vitamin D. Recently it has been found that human milk contain water soluble form of vitamin D (vitamin D sulfate) in good quantity. Read more…
Vitamin E: Deficiency and its Treatment and Toxicity
There is no clearly known deficiency disorder of vitamin E. But there is also no doubt that humans need tocopherol or vitamin E in his diet. The deficiency of vitamin E is seen only after resection of small intestine and in prolonged malabsorptive diseases, like celiac disease. There is also a very rare familial form of vitamin E deficiency disease, which is due to defect in alpha-tocopherol transport protein.
Children may develop vitamin E deficiency due to prolonged cholestasis (stasis of bile) or cystic fibrosis of long duration and this is characterized by hemolytic anemia and areflexia. If children suffer from abetalipoproteinemia, they develop vitamin E deficiency very rapidly as they can not absorb or transport vitamin E.
Symptoms of Vitamin E Deficiency:
Vitamin E deficiency causes degeneration of large myelinated axons. Peripheral neuropathy is also a major sign which is characterized by at first areflexia that progresses to ataxic gait and decrease in position and vibration sensation. Pigmented retinopathy, ophthalmoplegia and skeletal myopathy are some other symptoms of vitamin E deficiency. Deficiency of vitamin E increases virulence of viral infection due to increase in viral mutation.
Diagnosis of Vitamin E Deficiency:
Laboratory diagnosis of vitamin E deficiency is done by measuring the blood levels of ? tocopherols. Vitamin E deficiency is if the level of ? tocopherol is less than 5µgm/ml or ? tocopherol is less than 0.8 mg per gram of total lipids. Read more…
