ImmunoVET-EQ 21.2 oz | Thorne Vet

Immune Support for Horses - serum immunoglobulin concentrate in powder for easy equine dosing

  • Supports a healthy immune response
  • Improves gut barrier function
  • Maintains normal inflammatory cytokine production
  • In three convenient sizes for cats, dogs, and horses

ImmunoVET (ImmunoLin®*), an immunoglobulin concentrate of bioactive proteins, is derived from purified bovine serum. ImmunoVET contains at least 45 percent immunoglobulin G (IgG), plus lesser amounts of other immunoglobulins and bioactive proteins. The four primary bioactive proteins in ImmunoVET include:

  • Immunoglobulins – primarily IgG; an important part of humoral immunity
  • Transferrin – binds free iron, thereby preventing it from nourishing bacteria
  • Mitogenic growth factors – essential for nutrient utilization and helping to maintain a healthy gut barrier
  • Immune regulatory cytokines – known to stimulate secretion of secretory IgA, the body's first line of defense; help maintain a healthy inflammatory response
The gut is the first line of defense against invading organisms. Therefore, maintaining a healthy GI tract is essential for general immune support. ImmunoVET works with the animal's own immune system to help maintain gut barrier function. A 2002 study found bovine serum concentrate resulted in improved intestinal permeability, gut morphology (as measured by increased villous surface area and deepening crypts), and stool consistency.

Several animal studies have helped to elucidate the mechanisms of immunoglobulin concentrates in maintenance of a healthy immune response. In a 2004 study, immunoglobulin concentrate given to bacteria-challenged rats helped modulate the degree of activation of gut-associated lymphoid tissue (GALT). The intestinal secretory response was also decreased, leading to decreased water content of the stool.

Dietary bovine plasma protein concentrates, particularly the IgG fraction, improve lean tissue growth and protein metabolism. This may have implications in failure to thrive and wound healing.

Evidence from animal studies suggests ImmunoVET may help maintain a normal inflammatory response. A study of immune-challenged rats found immunoglobulin concentrate helps maintain a healthy cytokine ratio in the gut mucosa.

The naturally occurring proteins in purified bovine immunoglobulin are concentrated using stringent quality control procedures in a facility that is compliant with FDA Good Manufacturing Practices for food products. The concentration process takes place in a closed system, preventing contamination. Only beef cattle from herds in the United States are used in the production of ImmunoLin. Bovine serum concentrates have been used therapeutically in recovering malnourished children with no evidence of adverse effects.
