Importance of Amino Acids and Iron in Supporting the Immune System

Amino acids, both essential and non-essential, are crucial for the immune system's functioning. Monitoring protein levels and amino acid profiles, especially during infection, can indicate immune system health. Iron levels are also crucial, as infections often lead to low iron levels due to the body hiding iron to prevent replication of certain infections. Supplements like lactoferrin that bind to iron can help maintain normal iron levels during infections.
