When pregnant, it is officially recommended that you limit your intake of oily fish due to the risk of pollutants (toxins), please see NHS guidelines for these recommendations. Midwives and doctors sometimes caution the use of supplemented Omega 3, due to the risk of intaking Vitamin A - but our formula is 100 % free of Vitamin A and safe to use during pregnancy and after birth. Babies in the womb require a supply of Omega 3 essential fatty acid, as it cannot be made in the body by either the mother or the baby. It's especially important for brain, eye and cognitive development.
