Of course, being more visible to the acquisition of multiple vitamin supplements is convenience. It is much faster for a person to acquire a dose of a multivitamin supplement that contains each of the essential vitamins compared to the acquisition of each one individually. This is especially true of children as it may be the acquisition of a large number of vitamin supplements but one dose of a multiple vitamin supplement is far more tolerant.

Vitamin supplements may not always be the answer we are looking for in the balance of our diet and body. It is important to understand what role the different vitamins on our health in general and to understand how much of each of the vitamins that our body needs.

If you really need a vitamin dietary supplement is conviertira into something of value to our health, but can also be harmful to our health, drinking too much of a good thing.

If you are sure that you are not getting the right vitamins to provide what the body needs, then you should take a vitamin supplement can help you achieve optimal health. There are lots of vitamin supplements which to decide. In order to find the right vitamin product, it is necessary to interpret the labels and compare products.

Vitamin supplements are acquirable in a number of different forms, including capsules, tablets, liquids, and even chewable tablets. In addition, a wide variety in brands and the actual content of the vitamin supplement. Do a little research and find out what these supplements contain. Pay attention to dosages, ingredients, safety precautions, and other crucial. The right supplement for you, and if in doubt, consult a doctor or health care professional before taking any vitamin supplements.

Vitamin D which I will talk more specifically called vitamin D3 or cholecalciferol. It is synthesized in the skin by the action of ultraviolet (290-315 nm) cholesterol. It is also present in foods of animal origin such as fish oils.

Risk factors for vitamin D deficiency are: latitude, skin pigmentation, exposure to light and age.

Thus we do not synthesize all the same amount of vitamin D depending on where we live in the world, according to our age and our skin color.

To determine whether a prescription of vitamin D is needed for a blood 25OHD may be requested.

Since 2007, it is advisable to have a concentration of 25OHD> 30 ng / mL (75 nmol / L)

Lack of vitamin D during pregnancy may decrease the placental transport of calcium mediated PRHrP (parathyroid hormone) and thus the formation of bone mass. It was observed that children born to mothers deficient in vitamin D had a retarded growth, neonatal hypocalcemia, a linear growth and weight gain reduced.

This vitamin D deficiency is particularly true for women in Belgium and France, that may affect their child but also their own bone tissue.

Thus the recommended daily amount is not sufficient to increase the levels of vitamin D and remain above 30 ng / ml.

To maintain this rate exceeds 30 ng / ml should be given 800-1200 IU per day or 25,000 IU every 15 days or 100,000 IU every 2 -3 months.

It should be noted that mothers deficient in early pregnancy will always be an addition of 800-1600 IU / day. As more and more authors recommend additional contributions from 2000 to 10,000 IU during pregnancy and lactation!

B6 is required for transaminations of decarboxylation of dehydratase, reactions of side chain cleavage, and release of ammonia. Her group of aldehyde acts as a Schiff base to react with amino groups of amino acids. It basically acts to shuttle between the nitrogen compounds.

Functions

The three forms of B6 can all be converted to coenzyme PLP, which facilitates the transamination and the metabolism of proteins. PLP is essential for the degradation of glycogen, it also helps with the formation of the neurotransmitter, serotonin, in part, without protein hemoglobin (heme), nucleic acids, and lecithin. Vitamin B6 is essential for the metabolism of tryptophan to niacin.

Reactions:

· Transamination

These reactions are required to recycle and reuse the nitrogen in the body. They are the first step in the catabolism of amino acid and the last step in the synthesis of nonessential amino acids.

Example:

a-ketoglutarate glutamate oxaloacetate to aspartate

· Deamination of serine threonine (dehydratase)

This reaction provides the production of a-keto acids of serine and threonine by the movement of N as ammonia oxidizing

Example:

A-keto-serine serine NH4

· Decarboxylation

These reactions often occur on the seratonin neuroactive amines, tyramine, histamine, and GABA. They are also important in the synthesis of porphyrin intermediates in the synthesis of sphingomyelin, lecithin and taurine, and also for the degradation and desulfurization of cysteine.

Glycogen Phosphorylase ·

50% of all B6 in the body is bound to glycogen phosphorylase but the significance is unknown. The reaction is important for the reuse of folate and is as follows:

Glycine, serine methylene-THF 5.10

Insufficiency

The deficiencies of vitamin B6 are relatively rare. People with a diet deficient in vitamin B6 show first signs of weakness, irritability, insomnia, nervousness, and clammy skin lesions. More advanced symptoms include the failure of growth, impaired motor function, anemia microcytic hypochromic, the smooth tongue, and convulsions.

The impaired motor function and other mental problems may be attributed to a decrease in neurotransmitter amino acid-based (serotonin, GABA, tyramine, adrenaline). You see an increase of urea excretion due to decreased synthesis of nonessential amino acids. The nitrogen of these amino acids is not reused by transamination and the place is not excreted and is not lost. You see an increase in urinary excretion especially in amino acids: metabolites of glycine, methionine, and tryptophan. Microcytic hypochromic anemia is due to the fact that there is a reduced synthesis of the porphyrin ring depending on the B6 hemoglobin.

People who are at most risk include the elderly with poor intake of vitamin, alcoholics, hemodialysis patients, and those on drug therapy. In general, individuals with high metabolic stress.

- Proper control and management of stress and negative emotions.

- A good exercise regimen.

- Healthy eating.

- Get enough sleep.

- Time to distract.

- Living and working in healthy environments.

- To control and prevent the abuse of substances like caffeine, nicotine and alcohol.

- Good distribution and use of time and stress management.

It also could be defined as behavior that people have when exposed to harmful factors that pose risks to their health, it is estimated that one third of diseases in the world can be prevented through behavioral changes. The way people behave will determine who develops disease or remain healthy, and if they get sick, your role will be crucial in the recovery and the rate at which it occurs.

Lifestyle and cardiovascular health:

The increased level of cholesterol in the blood can lead to cardiovascular disease (myocardial infarction and cerebrovascular accident) within the main risk factors for these diseases are the snuff, hypertension and diabetes.

We could say that man is what he eats, what he does and the influence of environment, since according to the diet and habits to develop over the life will be contributing to a healthy or sick individuals of different inherited or acquired diseases across time.

One of the examples we can mention in lifestyle and cardiovascular health is the so-called Mediterranean diet which is defined as the usual diet in the sixties of the peoples of southern Europe, with a long life expectancy and ate lots of vegetables, fish, , olive oil, little meat, dairy and wine in moderation.

Studies in different countries examined the dietary habits, cholesterol level and cardiovascular mortality in different populations, providing the basis of character epidemiological healthy Mediterranean diet, establishing a direct relationship between consumption of saturated animal fat and the prevalence and incidence of mortality population coronary heart disease.

Lifestyle and osteoporosis:

In women the five years following menopause predispose to osteoporosis and fractures for various reasons. In general, adequate food and proper exercises, plus the modification of some factors linked to “lifestyle” may help reduce the risk of osteoporosis. Behavior changes are recommended:

- Leave the snuff

- Consume little coffee

- Eat small amounts of alcohol.

- Exercise.

- Balanced diet rich in calcium and vitamin D.

Osteoporosis (means “porous bone”) is the decrease in the amount of calcium from the bones, giving them less firm consistency that makes the person prone to fractures. The bone loss is slow and goes unnoticed until fractures occur.

The “Lifestyle” involved in the mineralization of the skeleton. Good eating habits and physical activity contribute to bone mineralization, consumption of alcohol, caffeine and especially SNUFF act otherwise.

It is essential in children and adolescents to promote a healthy lifestyle and with the same highlights the critical role played by nutrition and avoiding toxic habits, especially smoking, to reach the optimal acquisition of bone mass at the end of growth and thus reduce osteoporotic phenomena of adult life.

These are some of the examples we can mention where the lifestyle and the individual’s behavior throughout life affect their future health, there are many other diseases linked to lifestyle and will appear more over time , so it is necessary to educate people and prevent these diseases by decreasing the quality and life expectancy of people.

Vitamin B-3 (niacin)
Sometimes doctors prescribe high doses of niacin to help people improve fat levels in their blood. Niacin can:
Lowering LDL cholesterol.
Raise HDL cholesterol or high density lipoprotein. HDL cholesterol is often called “good” cholesterol because it can remove cholesterol deposits from artery walls and can send it to the liver for disposal.
To achieve these effects, niacin should be taken in doses greater than 1,000 mg per day. At these doses, niacin is considered a medication, not a supplement, and should only be taken under the advice of your doctor. High doses of niacin can be toxic. Side effects include headaches, cramps, nausea, itching, liver damage, gastrointestinal disorders, high blood sugar and irregular heartbeat. Blood tests are needed to monitor the results of regular niacin.

Vitamin B-6 (pyridoxine)
Vitamin B-6 works with vitamin B12 and folic acid to reduce homocysteine levels in blood. According to the National Academy of Sciences, the optimal intake of vitamin B-6 to prevent heart disease ranges between 1.5 mg and 50 mg per day.
Check with your doctor before taking vitamin B-6 if you have intestinal problems, liver disease, hyperthyroidism, or sickle cell anemia is under severe stress as a result of disease, burns, accidents or injury. High daily doses, especially over 250 mg per day, can cause peripheral nerve damage (neuropathy).

Vitamin B-9 (folic acid)
Folate is an important element in the formation of red blood cells. Folate is found naturally in foods, while folic acid is a synthetic formula found in nutritional supplements and fortified foods. Folate and folic acid can reduce homocysteine levels in blood.
Some studies have shown a decreased risk of heart disease among people with higher intakes of vitamins B-9 and B-6, both from diet and multivitamin supplements. Supplement with 400 micrograms of folic acid per day, which is the typical amount in most multivitamins, has no risk and could be considered for people with heart disease, despite the current lack of evidence of benefit.
For vitamin B-9, the daily recommended amount is 400 mcg. Good sources are citrus fruits, tomatoes, vegetables and grains. Now wheat flour fortified with folic acid, which can add an estimated 100 mcg per day to an average diet.

Vitamin B-12 (cobalamin)
Vitamin B-12 has a minor role in homocysteine levels and help her down only to people who are deficient in this vitamin. The absence of vitamin B-12 can cause anemia, and supplements are recommended for vegetarians who eliminate all animal foods from their diets. Injections of vitamin B-12 is recommended for people whose digestive tracts due to surgery, bowel disease or a hereditary problem, can not absorb the vitamin.

The following table shows the dietary recommendations of the supplements described above.
