Vitamin-Like Compounds and Plant Vitamins

For medical students2 min readUpdated 2026-10-10

Vitamin-like compounds, along with preparations of plant and animal origin, play an important role in pharmacotherapy. They are used as part of combination therapy for numerous pathologies, support the body's defense mechanisms, and accelerate tissue regeneration.

Vitamin B15Pangamic acid (calcium pangamate)
Vitamin B13Orotic acid
DermatologyVitamins H, N, and F enhance skin regeneration
Plant SourcesRosehip oil and syrup, sea buckthorn oil
Animal OriginCod liver oil, liver extracts

Classification of Vitamin-Like Compounds

Modern pharmacology distinguishes several key representatives of this group, each with a unique composition and structure:

Pharmacotherapeutic Significance

These compounds are widely used in medical practice:

  1. Prescribed predominantly as part of combination therapy for various pathological conditions.
  2. In dermatological practice, elements such as vitamins H, N, and F are actively used to stimulate and enhance regenerative processes in the skin.

Plant-Derived Vitamin Preparations

Agents of plant origin exert powerful pharmacological effects on the human body:

The main dosage forms here include rosehip preparations (fruit oil and syrup), sea buckthorn oil, as well as vitamin herbal mixtures, medicinal teas, and natural juices (e.g., carrot and cabbage juice).

Preparations of Animal Origin

This category of pharmacological agents represents specialized extracts from animal internal organs or their metabolic products. The main and most well-known representatives include:

Mnemonic

To remember vitamin-like substances, use the association: "Pangamate B15 and orotic B13, Lipoic N and F — fatty acids"

Frequently asked questions

What is the mechanism of the biochemical action of lipoic acid (vitamin N)?

Lipoic acid plays an indispensable coenzyme role in the oxidation and transfer of acyl groups within multi-enzyme systems. Its primary function is direct participation in the oxidative decarboxylation of alpha-keto acids, such as pyruvic and alpha-ketoglutaric acids. In multi-enzyme pyruvate and alpha-ketoglutarate dehydrogenase complexes, it serves as a prosthetic group. The pharmacological mechanism of action of lipoic acid preparations involves improving the oxidation of carbohydrate metabolism metabolites and cellular energetics.

In which specific diseases is the prescription of orotic acid (vitamin B13) indicated?

Orotic acid is used in medical practice as a growth stimulator in premature infants and to enhance hematopoiesis in certain anemias. Its prescription is also indicated to improve regenerative processes in affected internal organs in pathologies such as myocardial infarction and muscle dystrophy.

By what criteria do vitamin-like compounds differ from true vitamins?

Vitamin-like substances differ from true vitamins in their ability to be synthesized independently within the human body. At the same time, they are capable of forming functional coenzymes in the body, similarly to true vitamins.

What are the main pharmacological effects of plant vitamins?

Plant preparations enhance the body's defense mechanisms, exhibit adaptogenic activity under extreme loads, balance system functions, and stimulate tissue repair, promoting the healing of wounds and ulcers.

Why are vitamins H, N, and F used in dermatology?

In dermatological practice, these vitamins are prescribed to enhance regenerative processes in the skin.

What is traditional fish oil obtained from?

Fish oil is a preparation of animal origin obtained from the liver of cod.
