- What about milk allergies?
Transfer factors themselves are non-allergenic. Milk allergies are caused by the large milk proteins primarily casein, and to a lesser extent, the immunoglobulin. These common allergens, immunoglobulin and casein are removed from 4Life Transfer Factor® products.
- Can someone be allergic to transfer factors?
Unlike antibodies that are large molecules, transfer factors are quite small. Their small size makes them non-allergenic.
- Can persons who are lactose intolerant use 4Life Transfer Factor®?
Yes! Lactose intolerant persons can consume up to 3 grams of lactose without difficulty due to colonic bacterial digestion. The amount of residual lactose in 4Life Transfer Factor® is well below these sensitivity limits.

Everyone who needs an extra immune boost can benefit from taking 4Life Transfer Factor®.
- Is there a Transfer Factor product created for topical application?
