Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine, etc.)

Pyridoxine: what kind of vitamin?

The main role of the vitamin is to take part in protein metabolism. In addition, pyridoxine is necessary for carbohydrate and fat metabolism in the human body. Helps maintain the balance of potassium and sodium, which is especially important for the central nervous system, and stabilizes muscle function. If there is a lack of vitamin in the body, inflammatory processes in the middle ear may begin.

It is worth keeping in mind that pyridoxine is negatively affected by sunlight, water and high temperatures. Therefore, products that contain the vitamin should not be boiled or heat-treated.

Vitamin D

Vitamin D is the most “controversial”, since often in studies and meta-analyses scientists present conflicting conclusions about the benefits or even uselessness of a synthetic vitamin.

Vitamin D is a prohormone that is involved in various biochemical processes in the body. It is necessary for the normal function of the immune system, the prevention of cardiovascular and autoimmune diseases, and is an oncoprotector.

There are vitamin D2 and D3. The first form of the vitamin is found in food, and the second is formed in the skin from D2 under the influence of sunlight.

Global statistics show that about 70% of the world's population suffer from vitamin deficiency - mainly in northern countries. Its deficiency is clearly manifested externally - problems with skin, hair, nails and, of course, mood. Vitamin D deficiency is associated with a high risk of developing depression and anxiety.

An excess of the vitamin is difficult to achieve for Russian residents, so doctors often recommend taking a synthetic vitamin throughout the year for adults and children. You should consult a specialist about dosages.

Consequences of shortage

Due to a lack of vitamin B6 in the body, the following problems may occur:

• weakened immunity. Lack of pyridoxine leads to a decrease in antibodies that protect the body from harmful microorganisms;
• lack of glucose. In this case, fatigue, irritability appear, and sleep is disturbed. It happens quite often in pregnant women;
• imbalance of sodium and potassium. This usually results in swelling of the face, arms and legs. Sometimes the belly may become larger, which is not the cause of excess weight;
• problems with protein absorption. The lack of protein is associated not only with an insufficient supply of this useful substance, but also with a deficiency of pyridoxine. If you consume too many protein foods, their absorption may take up all the vitamin B6 that is present in the body.

Why is vitamin B6 needed and who is especially recommended to take it?

The main guarantee of good health and excellent well-being is an active lifestyle and a balanced diet, which influence a person’s magnificent appearance.
By eating certain foods, you can get a whole range of nutrients, vitamins and minerals, the lack of which leads to the development of diseases and deterioration of metabolic processes. Vitamins B6 containing pyridoxine play a special role in the synthesis of protein necessary for the human body, maintaining normal metabolism and reducing cholesterol levels in the blood and the absorption of fatty acids. This element is classified as water-soluble and quickly removed from human internal organs, so it is important to constantly nourish the body with it, which requires vitamin B6, which is an alternative to many food products.

Who should take it?

Vitamin B6 will be especially useful for the following categories of people:

• girls who use contraceptives or other means that contain estrogen;
• women in position. An excessive amount of estrogen appears in the body of a pregnant woman. Pyridoxine helps correct the situation;
• girls in the last 14 days before menstruation. There is also too much estrogen in the body;
• people who want to get rid of extra pounds;
• teenagers who have problem skin;
• patients with high blood sugar levels;
• persons with mental illness.

Vitamin B9 or folic acid

This vitamin is usually prescribed in tandem with B12 for a synergistic effect. Folic acid is also necessary for the immune and circulatory systems, is involved in the formation of new cells, and is needed for healthy metabolism.

The deficiency is manifested by neurological symptoms - anxiety, aggression, increased feelings of fear, and also contributes to the risk of developing panic attacks and depression. Against the background of excess, aggression and increased excitability also persist, and symptoms of digestive disorders appear.

Pregnant women and young mothers need additional B9 supplementation for a long time. Other people, as well as pregnant women, should be monitored and recommended by a specialist.

Indications for use

Vitamin B6 is often prescribed for the following conditions and problems:

• toxicosis during pregnancy;
• premenstrual period;
• diseases of the central nervous system, mental disorders;
• acute and chronic gastritis;
• anemia;
• skin diseases;
• in order to prevent negative effects as a result of taking various medications.

An acute lack of vitamin is observed in alcoholism and taking oral contraceptives.

Vitamin B12

The main source of vitamin B12 is animal products, so people who, for one reason or another, have excluded meat, fish and dairy products from their diet are at increased risk.

The vitamin is vital for hematopoiesis and the nervous system; it is involved in the synthesis of DNA components.

B12 deficiency is manifested by weakness, dizziness and tinnitus, increased irritability, memory loss, and signs of depression. Excess is accompanied by hives, and according to some reports, skin problems, including pimples and acne. People may experience allergic reactions and increased excitability. There are other symptoms, but these can be learned from laboratory tests.

How to use pyridoxine for hair

Vitamin-based hair masks are especially popular. They can be easily prepared at home. Pyridoxine has a positive effect on the condition of hair and stabilizes blood circulation.

For a vitamin mask you will need to purchase 4-5 ampoules of vitamin. You need to take 1 tbsp. l. burdock, castor and olive oil and stir well. Heat over low heat, add pyridoxine solution. Mix all ingredients well and you can apply the mask to your hair. Leave on hair for half an hour. Afterwards, rinse your hair well under warm water. After a couple of such procedures, you will notice how your hair will become softer, smoother and shinier.

Vitamin B6 intake rate

According to researchers at the US Institute of Medicine, the daily requirement of vitamin B6 is: from 1.3 to 1.7 mg for adults, 2 mg for women during lactation.

In the clinical guideline of K. Astill-Smith and K. Reardon, the recommended daily dose for different ages is

:

special instructions

People who have gastric and duodenal ulcers, as well as cardiac ischemia, should take it with caution. If you have liver problems, you can take the drug in small doses.

Pyridoxine can be stored for 36 months from the date of release. You need to keep the medicine in a dry and dark place away from children at a temperature of +8...+15 degrees.

It can be purchased at a pharmacy without a specialist prescription, but before taking it, it is better to consult with your doctor.

If you consume alcoholic beverages in excessive quantities, the absorption of the vitamin will decrease, and, consequently, the body will experience a lack of pyridoxine.

Symptoms of B6 overdose

It is difficult to achieve an overdose of the vitamin: at least, this is due to its hydrophilicity and inability to accumulate. So, at the moment, the upper permissible limit of consumption is 100 mg.

Manifestations of toxicity may include:

Help with oversupply

First aid for acute B6 poisoning consists of the following measures:

• stop taking the substance;
• rinse the stomach, induce vomiting if you accidentally consume a large amount;
• give adsorbents;
• contact a medical institution for medical help.

If symptoms of hypervitaminosis appear during prolonged use of high doses of the vitamin, it is necessary to discontinue the drug. In most cases, once the source of the problem is eliminated, the symptoms go away on their own. Antidotes are not used.

Nutraceutical support

First of all, there is a need to maintain the efficiency of the mechanisms that ensure the conversion of the amino acid homocysteine ​​back to methionine:

• vitamin B2 in active form - riboflavin-5-phosphate;
• pyridoxal-5 phosphate (B6);
• methylfolate (B9);
• methylcobalamin (B12);
• magnesium.

With elevated histamine levels, in addition to establishing the folate cycle, it makes sense to treat dysbiosis:

• berberine;
• oregano;
• thyme.

In addition, the use of strains of those bacteria that are capable of neutralizing histamine will be effective - in other words, the inclusion of probiotics:

• B. longum;
• L. gasseri;
• L. rhamnosus;
• L. plantarum.

Dosing when taking B6

To prevent hypovitaminosis B6 during heavy exercise or taking medications, an adult is recommended to take a short course (up to 10 days) of fortified dietary supplements containing 5-10 mg of the vitamin. This is enough to reduce the risk of vitamin deficiency. For children, the prophylactic dosage is selected based on age.

Therapeutic doses for correcting B6 deficiency can be tens of times higher than accepted norms.

The dosage and duration of the treatment course are selected taking into account the condition that has arisen.

Vitamin B6 is prescribed in tablets. For better absorption of the element, it is recommended to drink pyridoxine together with magnesium.

More details

Studies have shown that volumes over 100 milligrams are less absorbed with a single dose. If more than 100 mg is prescribed, then the daily dose should be divided into 2-3 times. Drink after meals.

B6 injections are prescribed when it is impossible to take tablets (impaired absorption of vitamins in the intestines, vomiting). A 1 or 5% injection solution is used, in 1 ml ampoules. Injections are given subcutaneously, intramuscularly or intravenously. The drug is administered into a vein after dilution with saline, but for injections under the skin or into a muscle, dilution of the medication is not required.

The duration of the course of injections is 10-15 procedures. Injections are given daily or every other day, alternating with other vitamin preparations.
