# Strengthening the Immune System with Peptides - **Author:** GAVAU.LT - **Published:** 2026-03-23 - **Updated:** 2026-09-02 - **Language:** en (English) - **URL:** https://www.gavau.lt/en/blogs/news/imunines-sistemos-stiprinimas-peptidais - **Image:** https://www.gavau.lt/cdn/shop/articles/photo-1584036561566-baf8f5f1b144.jpg?v=1775207725&width=1200 - **Publisher:** GAVAU.LT (https://www.gavau.lt) --- The immune system is our body's defence against infections, viruses and bacteria. However, with age the immune system weakens — this process is called **immunosenescence**. Peptide bioregulators are food supplements intended to help support the normal function of the immune system. The immune system – the body's defensive shield ## Contents 1.

Recommended programme 7. Additional forms of support ## How does the immune system work? The immune system consists of several main components: ### The thymus gland (thymus) where the T lymphocytes responsible for cellular immunity mature ### Bone marrow where all blood cells and immune system cells are produced ### Lymphatic system filters pathogens and supports the immune response ### Spleen filters the blood and takes part in the immune response With age the thymus gland shrinks (involution), so the production of T lymphocytes falls, and this significantly weakens immune function. Professor Vladimir Khavinson's team studied the effect of peptide bioregulators on immune system indicators. These food supplements are intended to help support the normal function of the immune system. ## Thymus peptides: Vladonix [Vladonix](https://www.gavau.lt/en/products/vladoniks-60-kapsuliu) is a natural peptide bioregulator (a cytomax) obtained from animal thymus tissue. It is one of the best-known peptide preparations for immunity. ### How Vladonix works: - Helps maintain the normal function of the thymus gland - Helps maintain the normal activity of T lymphocytes - Helps maintain cellular immunity - Helps maintain the balance of the immune system In clinical studies carried out at the Institute of Bioregulation and Gerontology, [Vladonix](https://www.gavau.lt/en/products/vladoniks-60-kapsuliu) was studied for its effect on immune system indicators in older people. ## A synthetic immune system peptide: Kristagen [Kristagen](https://www.gavau.lt/en/products/kristagen-60-kapsuliu) is a synthetic tripeptide (a cytogen) created in the laboratory and intended to support the immune system. It consists of three amino acids that precisely reproduce the most active fragment of the natural thymus peptide. ### Advantages of Kristagen: - Helps maintain the normal activity of immune cells - Helps maintain immunoglobulin levels - Contributes to maintaining the normal balance of the immune system - Suitable for vegetarians (synthetic origin) - A good maintenance preparation after a course of Vladonix ## Bone marrow peptides: Bonomarlot [Bonomarlot](https://www.gavau.lt/en/products/bonomarlot-60-kapsuliu) is a natural peptide bioregulator obtained from bone marrow tissue. Since the bone marrow is where all blood cells (including the cells of the immune system) are produced, this preparation matters for supporting immunity. ### How Bonomarlot helps immunity: - Helps maintain the normal processes of blood formation (haematopoiesis) - Helps maintain the normal activity of bone marrow cells - Helps maintain normal levels of leukocytes, erythrocytes and platelets - Helps maintain the body's natural resistance ## When is it especially important to support immunity? Peptide bioregulators for immunity are recommended in the following cases: The autumn–winter season when the body is under greater strain During periods of increased load during intense physical and mental work In older age when natural immune function weakens Under heavy stress stress significantly suppresses the immune system During periods of seasonally increased need when the body needs additional support ## Recommended immunity support programme ### Intensive programme: - 1 [Vladonix](https://www.gavau.lt/en/products/vladoniks-60-kapsuliu) + [Bonomarlot](https://www.gavau.lt/en/products/bonomarlot-60-kapsuliu) – a 30-day course (2 capsules a day of each) - 2 A break of 2-3 months - 3 Maintenance course: [Kristagen](https://www.gavau.lt/en/products/kristagen-60-kapsuliu) - 30 days ### Maintenance programme: - 1 [Kristagen](https://www.gavau.lt/en/products/kristagen-60-kapsuliu) – a 30-day course before the cold season (September-October) - 2 Repeat in spring (March-April) - 3 Once a year – a full course with [Vladonix](https://www.gavau.lt/en/products/vladoniks-60-kapsuliu) ## Additional ways to support immunity Besides peptides, the following matter for supporting immunity: - **Enough sleep** – 7-9 hours a night - **Vitamin D** – especially important in the Lithuanian climate - **Zinc and vitamin C** – the classic micronutrients for immune support - **Physical activity** – moderate-intensity exercise helps support immune function - **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 a good quality of life.
