About vitamins in general

Vitamins are biologically active agents, of small molecular size and diverse chemical composition, essential for the human body.

The intake of vitamins into the human body has to occur by a proper diet. A vitamin deficient nutrition may lead to pathological symptoms: in mild cases this is defined as vitamin deficiency, while more severe cases will lead to the complete lack of a vitamin. At the same time, excessive vitamin intake may also be harmful, defined as hypervitaminosis (for example following vitamin pill intake beyond any measure), which might also result in severe pathological symptoms.

A diverse diet usually covers the vitamin supplements; however, during the composition of our diet not only the vitamin richness of the raw food has to be pursued, but it also needs to be taken into account, that 10 to 50% of vitamins may get lost while preparing the meal.

Vitamins and the nervous system

In certain disorders nerves may be impaired; in such cases the high-dose intake of specific vitamins is proven to have a neural regenerative effect.

  • trauma
  • operative section
  • diabetes
  • alcoholic neuropathy
  • compression somewhere along the nerve tract
  • infections

Vitamin B1 - Thiamine

It has a major role in the carbohydrate metabolism, generates energy, contributes to the breakdown of carbohydrates and is essential for the normal function of the nervous system, muscles and heart.

Deficiency results in the accumulation of lactic and pyruvic acid in the body, leading to the manifestation of neurasthenic symptoms, loss of appetite, heart problems and even circulatory failure. This causes fatigue, weakness, depression as well as certain intestinal problems.

Vitamin B1 deficiency results in – primarily in oriental countries- a disorder named beriberi. Christiaan Eijkmann Dutch army-doctor from Malaysia is known for its discovery and treatment.

Dietary sources rich in thiamine:

  • cereals, brown bread, whole grain pasta
  • pulses
  • nuts, oily seeds: 100-2020 μg (upper value is the sunflower)
  • liver,

Vitamin B6 - Pyridoxine

Its major role is in the modification of amino-acids. Deficiency may lead to so called pellagra symptoms on tongue and skin, inflammation of peripheral nerves, anemia and epileptic seizures combined with nervous system disturbances. Further deficiency symptoms may be: cracking of the lip mucosa, excessive function of sebaceous glands, irritability, insomnia, muscle weakness, hair loss, and limb spasms.

Vitamin B6 supplementation is recommended in cases of migraines, as well as pregnancy. It is safe to administer for nausea during pregnancy.

Dietary sources containing vitamin B6:

  • liver,
  • fish,
  • meat,
  • dairy products,
  • pulses,
  • cereals,
  • spinach,
  • banana,
  • yeast,

Vitamin B12

Vitamin B12 contributes to the synthesis of nucleic acids, it affects the protein synthesis of the body, promotes the incorporation of amino-acids into proteins and increases their efficacy. In medical practice it is used in cases of pernicious anemia, worsening of general condition, exhaustion, neural inflammation, recovery from a chronic illness. It is characterized by an invigorating, corroborative effect exerted on the whole body.

Vegetables do not contain vitamin B12, supplements can only be provided by animal source food.


High dose vitamin B supplements may influence the absorption and effect of some other medications. Their intake should follow medical supervision; this is exactly why a prescription is required. It is important to note, that taking vitamin supplements with neural regenerative effect won’t result in a miraculous outcome right away, nerve re-formation is a slow process, it may take months to regain function.
