Additional Natural Immune Support
dosage is 400 to 800 IU of natural source vitamin E (dalpha
tocopherol).
Vitamin A was once known as the “anti-infective
vitamin” and has recently regained recognition as a
major determinant of immune status. Vitamin A affects
the immune system in several ways. Primarily, it plays
an essential role in maintaining the surfaces of the skin,
respiratory tract, gastrointestinal tract, and other body
tissues as well as their secretions. These surface systems
constitute a primary barrier to microorganisms. In addition
to this role, vitamin A has been shown to stimulate
and/or enhance numerous immune processes, including
induction of anti-tumor activity, enhancement of
white blood cell function, and increased antibody
response. Vitamin A has also demonstrated significant
antiviral activity and has prevented the immune
suppression induced by adrenal hormones, severe
burns, and surgery. During an acute viral infection, a
single oral dose of 50,000 IU for one or two days
appears to be safe even for infants. In general, however,
the daily dosage of vitamin A for immune support
should be 5,000 to 10,000 IU. Beta carotene can be
used instead and may offer some benefits greater than
vitamin A.
