She recommended fish oil.
My mother suggested that I add fish oil to my diet. She said that fish oil supplements are thought to help the body get the good DHA health benefits of fish but that it is concentrated in fish oil. She also recommended pharmaceutical grade fish oil rather than the various cheap fish oil capsules you see for sale. She explained that fish oil is a natural product and not subjected to regulation, so you need to be a careful consumer. Ceap fish oil capsules might not be as fresh or pure as the pharmaceutical grade product. Some cheap kinds are shipped in tanks for long journeys and then have preservatives are added to them. I will try pharmaceutical grade fish oil to be sure it contains the best quality oil.
