B vitamins

This is a group of water-soluble vitamins essential for energy production, nervous system function, and cellular metabolism. This group includes the following vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folic acid), and B12 (cobalamin).

Natural sources of B vitamins

B vitamins can be found in various foods: meat (especially liver), fish, eggs, dairy products, whole grains, legumes, nuts, and seeds. Some vitamins, such as B12, are only found in animal-derived foods, so supplements are often recommended for vegetarians and vegans. Supplements are available in capsules, tablets, or liquid drops.

Recommended daily allowance of B vitamins

The recommended daily allowance of B vitamins depends on the specific vitamin. For example, B12 can be prescribed from 25 to 500 mcg or more, and B6 from 1.3 to 100 mg. The precise doses of B vitamins are selected individually, taking into account age, health status, diet, and blood test results.

Possible side effects of B vitamins and interaction with medications

B vitamin supplements are generally well tolerated, especially when taken at recommended doses. However, excessive amounts can cause side effects. For example, too high a dose of vitamin B6 can lead to nerve sensitivity disorders, tingling, or muscle weakness, while B12 can cause skin rash, irritation, or itching.

B vitamins can interact with some medications, such as antiepileptics, antibiotics, or antihypertensives. Therefore, consult a doctor or pharmacist before taking them.
