Features of B vitamins
Group B vitamins are water-soluble substances that easily break down during heat treatment, as well as under the influence of caffeine, alcohol, nicotine and refined sugar.
It is impossible to get an excess of B vitamins by consuming their rich foods, because their excess is removed from the human body along with physiological excreta. But in case of random reception of medicines containing vitamins of this group, the excess can cause intoxication, which is expressed in general excitement, the onset of headache and insomnia, increased heart rate, and sometimes the development of convulsive seizures. Therefore, to take medicines containing vitamins of group B, it is necessary strictly according to the doctor`s prescription.
Necessity of taking vitamins of group B
The need for preparations of B vitamins increases in people suffering from a variety of diseases and using antibiotics for treatment. The fact is that in the process of taking antibiotics, B vitamins are very actively excreted from the body, which has a very negative effect on the course of treatment. Therefore, their receipt of food is clearly not enough.
With such diseases of the gastrointestinal tract as gastritis, peptic ulcer and colitis, taking medications containing B vitamins is extremely important.
Increased fatigue, chronic fatigue, weakness, memory impairment and decreased performance indicate a deficiency of B vitamins in the body and are the reason for their additional intake. If you do not pay attention to these symptoms on time, they can be replaced by such serious neurological disorders as nervousness, a constant sense of fear, numbness and tingling of the fingers and toes, sleep disturbance and prolonged depression.
The intake of B vitamins, accompanied by the use of sorbents, antibiotics, anticonvulsants, leads to their inadequate assimilation.
An additional intake of B vitamins is important for pregnant and lactating women, as well as for people who use hormonal contraceptives.
How to take B vitamins
Some B vitamins, such as B1, B2, B3, B6 and B12, which are part of chemical additives and vitamin complexes, can cause allergic reactions. Therefore, it is more expedient and safe to receive them from food products.
Vitamins of group B are rich in foods such as meat, liver, carrots, cabbage, sea fish, eggs, butter, potatoes, nuts, cereals, brewer`s yeast, yellow fruits, green plant parts and dairy products.
When taking vitamins of group B, it should be taken into account that their simultaneous action on the body gives better results than the intake of each vitamin group individually. In natural products, these substances are most often present in the same products, which explains the occurrence of a deficiency of B vitamins with malnutrition. Therefore, if you decide to enrich your body with these vitamins, your daily menu should consist of the most diverse products in which they are contained.
