Lactoferrin supplementation during pregnancy - a review of the literature and current recommendations.

Pregnancy is a period which requires special care and attention. Maintaining health during pregnancy helps to avoid birth related complications and is the best way of promoting a healthy birth. Besides a daily intake of folic acid, iron, iodine, vitamin D3 and A, calcium and polyunsaturated fatty-acids, as recommended by health agencies, supplementation of lactoferrin - a protein of multidirectional biological activity and proven safety of use - seems to be beneficial. A wide range of lactoferrin biological roles (including regulation of iron balance, modulation of immune responses, antimicrobial, antiviral, antioxidant, and anti-inflammatory activity) may contribute to better pregnancy and birth related outcomes.
