How does the immune system work?
The immune system consists of several main components:
- Thymus (thymus gland) - where T lymphocytes mature, responsible for cellular immunity
- Bone marrow - where all blood and immune system cells are produced
- Lymphatic system - filters pathogens and maintains the immune response
- Spleen - filters blood and participates in the immune response
With age, the thymus shrinks (involution), resulting in decreased T lymphocyte production, which significantly weakens immune function. Professor Vladimir Khavinson's research has shown that peptide bioregulators can help slow this process and maintain immune function.

Thymus peptides: Vladonix
Vladonix is a natural peptide bioregulator (cytomaxes) derived from animal thymus tissues. It is one of the most important peptide preparations for immunity.
How Vladonix works:
- Supports thymus function and slows its involution
- Promotes T lymphocyte maturation and differentiation
- Helps maintain cellular immunity
- Regulates immune system balance (important in cases of autoimmune diseases)
In clinical studies conducted at the St. Petersburg Institute of Bioregulation and Gerontology, Vladonix use improved immune system indicators in elderly patients, reducing the frequency and severity of seasonal infections.
Synthetic immune system peptide: Kristagen
Kristagen is a synthetic tripeptide (cytogen) created in the laboratory and designed to support the immune system. Its composition consists of three amino acids that precisely replicate the most active fragment of the natural thymus peptide.
Kristagen advantages:
- Stimulates immune cell production
- Helps maintain immunoglobulin levels
- Regulates cytokine balance
- Suitable for vegetarians (synthetic origin)
- Excellent maintenance supplement after a Vladonix course

Bone marrow peptides: Bonomarlot
Bonomarlot is a natural peptide bioregulator derived from bone marrow tissues. Since bone marrow is the production site for all blood cells (including immune system cells), this preparation is important for immune support.
Bonomarlot benefits for immunity:
- Supports hematopoiesis (blood formation) processes
- Stimulates stem cell activity
- Helps maintain normal levels of leukocytes, erythrocytes, and platelets
- Strengthens the body's resistance to infections
When is it especially important to strengthen immunity?
Peptide bioregulators for immunity are recommended in these cases:
- Autumn-winter season - preparing for the cold and flu season
- After illness or surgery - during the body's recovery period
- In older age - when natural immune function weakens
- During high stress - stress significantly suppresses the immune system
- In cases of chronic infections - when the body is constantly fighting infections
Recommended immunity strengthening program
Intensive program:
- Vladonix + Bonomarlot - 30-day course (2 capsules per day of each)
- Break of 2-3 months
- Maintenance course: Kristagen - 30 days
Preventive program:
- Kristagen - 30-day course before the cold season (September-October)
- Repeat in spring (March-April)
- Once a year - full course with Vladonix
Additional ways to strengthen immunity
In addition to peptides, the following are important for strengthening immunity:
- Adequate sleep - 7-9 hours per night
- Vitamin D - especially important in northern climates
- Zinc and vitamin C - classic immunity support micronutrients
- Physical activity - moderate-intensity exercise strengthens immunity
- Stress reduction - chronic stress is one of the greatest enemies of immunity
- Probiotics - gut health is closely linked to immunity
Investing in immune health is an investment in quality of life. Peptide bioregulators provide your body with additional support that is especially important in the modern world. Browse our product catalog and start strengthening your immunity today.
