Selenium (Se) concentration in human milk in Poland is below 10 ng ml −1 and the Se intake by breastfed infants is about 6 μg day −1 . Supplementation of lactating mothers with selenium‐enriched yeast increases rapidly and significantly the Se concentration and glutathione peroxidase activity in maternal blood components. Se concentration in milk is also significantly elevated. After 1 month the mean Se intakes by breastfed infants were greater than the recommended dietary allowance of 10 μg day −1 for infants from birth to 6 months of age.
