Is Phenylalanine Safe for Breastfeeding Women?
At this time, no information is available suggesting that phenylalanine supplements are either safe or unsafe for breastfeeding women. It might seem logical to assume that phenylalanine supplements would be perfectly safe for breastfeeding women, since it is an amino acid that is found naturally in many foods. However, just because a normal dietary intake through food is safe, it cannot be assumed that using phenylalanine supplements medicinally is equally safe. Perhaps the higher levels could cause problems, or perhaps the phenylalanine in supplements is slightly different from the phenylalanine found in foods. Until more information is available, it is best to wait until after weaning your child to try phenylalanine supplements.
