What is lactoferrin and will it really strengthen my immune system?

Answer:

Lactoferrin is a protein found in human and cow's milk. Sold as a supplement, lactoferrin is often promoted for supporting or strengthening the immune system, preventing infections and improving gut health.

Laboratory evidence suggests lactoferrin may have antimicrobial, antioxidant, anti-inflammatory, immunomodulatory and anticancer properties.

Preliminary clinical studies have investigated the effects of lactoferrin supplementation for reducing the occurrence of serious infections preterm infants, preventing and treating anemia in women and infants, preventing and treating colds and vaginal infections, reducing acne, and improving taste and smell for people undergoing chemotherapy. However, more research is required to establish the efficacy of lactoferrin for treating or preventing any of these conditions. Although lactoferrin generally appears to be safe, be aware it may trigger a reaction in people with milk allergies.
