Research objectve To determine whether a unique garlic supplement (Allisure) that contains only stabalized allicin could prevent colds in healthy
  • 65% reduction in common cold.
  • 80% reduction of severity of symptoms and duration
  • 90% reduction of re-infection
  • Product is well tolerated and offers many other advantages according to volunteer report


  • The result overwhelmingly favored the supplement of allicin as a preventive measure, demonstrated accelerated relief and reduction in the severity of the symptoms
  • A reduced likelihood of becoming re-infected with other viral strains indicated general improvements in the immune system with the active supplements
2. Antimicrobial Effects: Research Summary
Antimicrobial effects Garlic is effective against a wide range of both Gram positive and negative bacteria, including:

  • Salmonella Normally causes septicemia and produces typhoid or typhoid-like fever in humans.
  • Staphylococcus, Clostridium Food poisoning.
  • Streptococcus Causes septic sore throat and scarlet fever as well as other pyrogenic and septicemic infections.
  • Klebsiella, Proteus, Escherichia Causes gastroenteritis, cute and chronic gastrointestinal disease.
  • Bacillus Responsible for foodborne illness
  • Mycobacterium The cause paralytic illness, wide range of symptoms from food poisoning to gas gangrene.

Immune effects Garlic can stimulate and boost human immune system.

  • Increases number of lymphocytes A type of white blood cell involved in the human body’s immune system.
  • Increases number of phagocytosis Serve to remove foreign bodies and thus fight infection.
  • Increases natural killer cell activity Also known as NK cells, K cells, and killer cells, these are a type of lymphocyte (a white blood cell) and a component of innate immune defense. These cells do not destroy the attacking microorganisms directly; they attack infected cells and possible cancerous cells.
  • Increases antibody titers Antibody titer is a test that measures the presence and amount of antibodies in blood. These antibodies may be against a particular type of tissue, cell, bacteria, virus, or other external substance.
