Too Much of a Good Thing: What You Don't Know About Vitamin Overdose

These days, supplements abound on the market, all touting the various health benefits that come with taking them regularly. Many people believe the hype and pop these supplements like candy. But as the saying goes, too much of a good thing is bad for you. Apparently, that saying applies to vitamins as well. In fact, the phenomenon of vitamin overdose is surprisingly little known for something that is as pervasive as the fad of taking all sorts of vitamin supplements. Unfortunately, these supplements not as regulated as other medications. Many overdose on vitamins because they don't understand what it is and the role it plays in the body.

Vitamins are substances found in the plants and animals that your body needs for normal function, growth, and health. The human body cannot manufacture these vitamins, and in some cases cannot store it in huge amounts. Each vitamin has a specific function, and they are involved in many processes that enable your body to use carbohydrates, fats and proteins for energy and repair. They can be classified into two categories: fat-soluble vitamins and water soluble vitamins. Fat-soluble vitamins are absorbed by the body using bile acids, and are stored until they are needed. Among these are vitamins A (retinol), D (calciferol, commonly referred to as the sunshine vitamin), K and E (tocopherol). Water-soluble vitamins are easily absorbed by the body, but it cannot be stored and all excess is quickly flushed out through urine. Among these are vitamins B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B12 (cyanocobalamin), C (ascorbic acid), H (biotin), and Folic Acid. If you have low levels of certain vitamins, regardless of whether it is a water-soluble or fat-soluble vitamin, you may develop a deficiency disease. Some of the more familiar vitamin deficiency diseases are rickets (lacking vitamin D), scurvy (lacking in vitamin C), pellagra (lacking in B3 or niacin), and beriberi (lacking in B1 or thiamine).

On the opposite end of the spectrum, multiple vitamin overdose is basically being poisoned by vitamins. This is most commonly observed in patients taking the fat-soluble vitamins A and D, as well as concentrating on a specific B vitamin. Obviously, this occurs when you have too much of a particular vitamin or number of vitamins, and the gravity of the overdose is largely determined from person to person, depending of their age and state of health. As with the overdose of any drug, the imbalance causes unwanted side effects that are potentially life-threatening. The most common symptoms of vitamin overdose are diarrhea, irritability, dehydration, decreased appetite, constipation, fatigue, nausea, and vomiting. These symptoms may disappear if the dosage is reduced.

However, in some cases, the overdose may greatly affect your overall health. For example, if you have a vitamin D overdose, this will cause the calcium levels in your blood to rise to toxic levels, causing damage to soft tissues, bones and kidneys, and possibly cause kidney stones to form. An overdose of vitamin A may cause liver problems, excessive skin dryness or peeling, coarse bone growths and reduced bone mineral density. Pregnant women must be especially careful not to overdose on vitamins because it may cause potentially serious birth defects.

The best way to get vitamins is through consuming nutritious food. To avoid a vitamin overdose, do not take more than the recommended daily dose of supplements. It would be wiser to consult a doctor before taking any vitamin supplement, especially if you are pregnant or suspect you may be pregnant, have a preexisting medical condition or are taking prescription medication regularly. Vitamin overdose is extremely preventable as long as you remember that everything must be take in moderation.

Understanding and Treating Fatigue

Fatigue or the inability to continue functioning at the same level of normalcy is becoming more common in modern life. It is often caused by a lack of energy to the point of exhaustion. This condition is normal, but it can be hazardous if it becomes constant. Constant fatigue is called Chronic Fatigue Syndrome (CFS). Individuals who suffer from CFS may have a hard time working efficiently and feel weary and irritable. The real causes of fatigue are still unknown, but doctors and other health specialists suggests that two of the major causes of this condition is depression and vitamin deficiency.

Depression is one of the major probable causes of CFS. Some factors that may contribute to depression can be life altering events that cause mental and physical exhaustion. Family problems like divorce, child care, and other issues may eventually cause depression. In addition to these factors, depressed individuals easily get tired because these individuals produce less cortisol, a hormone that is produced by the adrenal gland. Scientists found out that people with CFS sometimes produce less cortisol and probably affect the immune system.

Many medical studies show that individual who suffer CFS suffer from vitamin deficiency. People need vitamins and minerals for good health, proper well-being, and energy. People with low vitamin levels tend to be tired, weak, and sometimes irritable.

Other symptoms of CFS may include the following:

· night sweats
· weight change
· breathing difficulties
· swollen lymph glands
· persistent feelings of thirst

Individuals who suffer from CFS are encouraged to engage in active lifestyles and healthy food regimens. Including exercise and other physical activities as part of a daily routine may promote the release of endorphins, which are chemicals released by the brain that are said to promote feelings of bliss and elevates mood. Exercise may also improve blood circulation and oxygenation to various parts of the body and prevent CFS of developing.

Health specialists also advise these individuals to take B complex vitamins. These vitamins includes a group of eight vitamins which includes thiamine (B1), roboflavin (B2), niacin (B3), pyridoxide (B6), folic acid (B9), and cyanocobalamin (B12). These B-complex vitamins may help fight fatigue and is vital nutrient for the formation of red blood vessels. These blood vessels are linked to the human body's energy levels. These B-complex vitamins work by maintaining the energy levels high. They can also help prevent the development of some diseases because they may aid in the repair of nucleic acids and the immune cells.

Most people who take B complex vitamins notice increased energy immediately because this kind of supplementation converts carbohydrates into glucose, which is converted by the cells into energy.
Physical activity coupled with B-complex may prevent CFS and lead to improved overall health.

However, individuals who want to include physical activities and vitamins in their daily routines should seek the approval of doctor, nutritionists, and other health professionals. Some exercise routines may not be appropriate for some individuals and B-complex vitamins may interact with other drugs and supplements and develop unwanted side effects. These professionals may devise a health program and food regimens that are appropriate for the development of one's health.
