• Arginine helps to prevent bacterial & viral diseases in persons with suppressed immune systems

• Arginine blocks the formation of some forms of cancer (Arginine inhibits the cellular replication
of 24 different types of cancer in animals)

• Arginine boosts the ability of the immune system to fight breast cancer

• Arginine lowers tumor protein synthesis and tumor growth rate in liver cancer patients

• Arginine inhibits the further growth of some types of sarcomas

• One of the means by which Arginine counteracts cancer is by reducing the activity of ornithine decarboxylase, an enzyme that is associated with some types of cancer. (Caution: Arginine is also speculated to exacerbate some types of cancer; however this is not well proven)

• Arginine improves outcome of cancer treatment

• Arginine (in non-excessive quantities) stimulates numerous aspects of the immune system

• Arginine stimulates the production of helper T-cells

• Arginine stimulates the activity of lymphocytes and also stimulates their production
by the thymus gland

• Arginine increases the activity (cytotoxicity) of NK lymphocytes

• Arginine stimulates the production of T-lymphocytes within the thymus and makes
them more active and effective

• Arginine increases the size of the thymus, stimulates the production of
lymphocytes by the thymus and restores the production of thymic hormones
to youthful levels

• Arginine helps to counteract inflammation

from surgery
