Omega 3 is an essential polyunsaturated fatty acid used by the body & may help to maintain a healthy heart & brain function. It is ‘essential' because our body cannot make omega 3 but rather it must be obtained through our diet. It is generally accepted that oily fish are high in omega 3, however, flaxseed is one of nature's richest plant sources of omega 3 with 51 percent of the fat being this important fatty acid. One serving (30g/1oz) of linwoods milled organic flaxseed provides 7.2g of omega 3.
