Customer question: Can I give Transfer Factor to a child who has previously shown sensitivity to cow’s milk protein? How is Transfer Factor produced?
Legal disclaimer
4Life products are food supplements and not medicinal products. They are not intended to diagnose or treat any condition. Decisions regarding supplement use in children (not younger than 4 years old) should always be made in consultation with a healthcare provider. The information in this article is for educational purposes only.
What exactly is Transfer Factor Classic?
Transfer Factor Classic is a food supplement from 4Life Research USA that contains an ingredient called Transfer Factor XF, derived from bovine colostrum. Colostrum is the first milk produced by mammals after birth. However, Transfer Factor XF is not whole colostrum — it is an extract of selected immune fractions.
This was the very first product launched by 4Life in 1998, and it remains a bestseller thanks to its simple formulation. According to customer reviews, for many families, it is a popular choice for nutritional support — especially when starting supplementation for the first time. We remind you however once more that 4Life Transfer Factor products are not intended for children under 4 years of age and that any supplementation in children must be consulted with a doctor.
Its production follows regulations for food supplements in the United States. While it is based on milk-derived raw material, it does not contain the full range of milk proteins. Still, the label correctly lists its bovine origin in accordance with food safety rules.
What about milk sensitivity?
As long-time distributors of Transfer Factor products (since 2004), we have met many parents who choose Transfer Factor Classic for children with sensitive digestion or a history of milk-related sensitivity. While we are not healthcare professionals, we can share that many clients have reported good tolerability of this product.
Some individuals may react strongly to supplements containing whole colostrum from other manufacturers — likely due to the presence of lactose, casein, or bovine immunoglobulins. In contrast, Transfer Factor XF is a more refined extract, containing only selected fractions.
Still, individual responses to food ingredients can vary, and no supplement is universally tolerated. It is always important to consult your doctor before using any new supplement with children.
