I supplement with fish oil + borage oil because I have found them to completely relieve all menstrual cramping. I now have no menstrual cramping whatsoever. Prior to supplementation, I have always eaten fairly large amounts of omega-3 rich fish ie daily sardines, plus salmon or other fatty fish at least twice per week. However, I still had menstrual discomfort until I began supplementing with fish oil + borage. I also like the taste of coconut oil and use it on vegetables instead of butter, and sometimes for sauteeing. Some on this list have mentioned that coconut oil can help a sluggish thyroid. I am wondering if there is any harm in taking supplements of highly unsaturated oils such as fish oil/borage (I know that they are very prone to peroxidation in the body) plus highly saturated fat such as coconut oil? Will the fish oil/borage slow my thyroid function?
