Quest Omega 3 & 6 provides a balance of the Omega 3 and Omega 6 fatty acids - which are termed "essential" fatty acids as they are not synthesised by the body, but are vital for the efficient functioning of the cells. Essential fatty acids are sources of chemical messengers that play a major role in the regulation of the cardiovascular system, the nervous system and the inflammatory response. Use during pregnancy to support the optimal health of mother and baby - and at other times to support cardiovascular, joint and mental well-being. This is an everyday supplement to support optimal health. It contains the same balance of Omega 3 and Omega 6 essential fatty acids that are found in breast milk.
