If you are taking Vitamins please read some unknown myths

Everybody knows that Vitamins are compounds that are needed by the body for good health. The human body cannot synthesize its own vitamins (other than vitamin D in the skin), and so these must come from the diet. There are a lot of myths about vitamins, here are some important one:


Expensive Vitamin Supplements Are the Best
Myth

There are many different combinations of vitamins on the market and some are very expensive. For people who are concerned that their diet doesn’t provide all the required vitamins and minerals, a simple, low-cost multivitamin supplement will be enough.


Supplements Are Essential
Myth

It is possible to get all the vitamins needed from a balanced and healthy diet, though some people may need extra Supplements. (e.g., pregnant women). They should be taken only with the advice of a doctor, nurse or pharmacist.


Natural Things Are Always Safe
Myth
There are some very dangerous toxins in nature, such as botulinum toxin from bacteria, tetrodotoxin from puffer fish, and batrachotoxins from poison arrow frogs, amongst others. Even vitamins, which are essential for life and health, can be toxic in the wrong amounts.

 
Vitamins Can Replace Healthy Eating
Myth

Some people belief that they can make a poor diet better by just adding in a vitamin supplement – this is a myth, because a healthy diet is about more than just the recommended daily intake of vitamins. It’s important to east food with the right minerals, with plenty of fibre, low fat protein and whole grains, avoiding too much fat and sugar.


Vitamins are better absorbed when taken in a spray form.
Myth

The vast majority of people absorb vitamins easily. Therefore using the vitamin in spray form is totally unnecessary for most people.


Vitamin C fights colds
Myth

In 2007, study of more than 11,000 subjects that found vitamin C didn't ward off colds, except among marathoners, skiers and soldiers on subarctic exercises. However MacKay said a meta-analysis showed taking vitamin C may reduce the duration of a cold by 8 percent in adults and more than 13 percent in children, though he pointed out the research is not conclusive.


Extra Vitamins Make Your Hair Thicker and Stronger
Myth

Taking vitamins won’t make it any hair stronger unless they become brittle or is falling out as a result of a vitamin deficiency. The thickness of hair is generally inherited, and so extra vitamins can’t change this either.


Natural Vitamins Are Better Than Synthetic Vitamins
Myth

Vitamins from natural sources are identical to vitamins from synthetic sources, and are used by the body in exactly the same way. Vitamins in food seem to have more of an effect than vitamins taken as supplements. It’s not completely clear why, but it may be because they work together with all the other parts of the food, such as the other nutrients and fibre. It is better to get as many vitamins as possible from a balanced diet rather than as a supplement.



Natural form of vitamin E is better than the artificial.
Myth

It is natural vitamin E, if the label on your bottle says’d-alpha tocopherol' and it costs about twice as much as the synthetic form. The bottle of synthetic vitamin E will mention 'dl-alpha tocopherol'. But there is no special advantage. The decision ultimately lies with a consumer, as some people prefer everything natural.Studies suggest that vitamin E helps people with diabetes, colon cancer, Parkinson's disease, heart disease, cataracts and Alzheimer's. The bottom line: Choose synthetic or natural, whichever suits your budget. You'll be getting great benefits either way.


Foliate and folic acid is the same thing
Myth
The two terms are often used interchangeably. But the fact is that folate comes from plants, while folic acid is the synthetic form, which is always used in supplements and fortified foods. Folic acid is also roughly twice as potent as folate. Studies show that pregnant women who take folic acid supplements lower the risk of neural tube defects in newborn babies by about 50%.


If Small Doses of Vitamins Are Good
Myth

It is important to get the recommended daily allowance (RDA) of all the vitamins, but taking large doses (also known as mega-doses) can be harmful, especially for the fat-soluble vitamins that are stored in the body, but also for some of the water-soluble vitamins too. For example:

-too much vitamin A can cause problems for unborn babies, and can lead to blurred vision, headaches and sickness
-too much vitamin B3 (niacin) can lead to liver problems
-too much vitamin B6 can cause pins and needles and numbness in the feet and hands, and unsteady gait
-too much vitamin C can cause diarrhoea, and can lead to kidney stones
-too much vitamin E can cause blood-clotting problems
