This is something I have only heard mentioned in the past few years. Before that I was like "Omega what"??? Many doctors recommend taking a supplement of Omega 3 fatty acids. The benefits are varied, but the ones that interest me the most were that I heard they can help with acne and recenltly was told they help nerve function which helps with depression, anxiety and probably other common female issues. I found this cool info if you have the time to check it out, it tells you foods that contain these fatty acids and interesting to remember that it is more effective to get them from food than supplement pills. So, eat your walnuts and salmon!
