The GAPS™ Nutritional Program is based on theories which have achieved great popularity in the scientific community and been confirmed by various studies.

Most people with the GAPS condition have Gut related problems, which started from compromised gut flora. The microbial status of the human body establishes and supports the numerous functions:

  • Appropriate digestion,  absorption and elimination of food, preventing the most common deficiencies in magnesium, zinc, selenium, copper, calcium, manganese, sulphur, phosphorus, iron, potassium, vanadium, boron, vitamins B1, B2, B3, B6, B12, C, A, D, folic acid, pantothenic acid, omega-3, 6, 9 fatty acids, taurine, alpha-ketoglutaric acid, glutathione and many other amino-acids
  • Prevention of Anemia, because many abnormal pathogenic bacteria species are iron-loving  
  • Synthesis of various nutrients: vitamin K, pantothenic acid, folic acid, vitamins B1, B2, B3, B6, B12, various amino-acids and proteins
  • Protection for the gut surface from invaders and toxins by providing a natural barrier and producing a lot of anti-bacterial, anti-viral and anti-fungal substances, preventing intestinal permeability (“Leaky” Gut)
  • Nourishment and energy production (60 – 70%) for the gut lining
  • Appropriate production of immune cells, immunoglobulins and other parts of the immunity
  • Balance of immune system and prevention of autoimmunity
  • Control of the different opportunistic and pathogenic bacteria, viruses and fungi (most common are –  Candida and Clostridia species); preventing them from producing toxic substances, which get absorbed into the blood stream, carried to the brain and cross the blood – brain barrier, causing different neurological and psychiatric symptoms (“Leaky” brain).

The GAPS Nutritional Program is based on “Healing and Sealing” the gut lining, optimizing microflora, preventing non-adequate immunity, faulty brain functioning and establishing long term nutritional and microbial balance for the body. This approach will help children and adults with Gut and Psychology/Physiology Syndrome to be healthier and have an independent, productive and happy lifestyle.
