Pharmaceutical grade is better
Many people use fish oil as an antioxidant, but unless they are using a quality fish oil product, they may be doing their body more harm than good. Pharmaceutical grade fish oil is better than the cheap fish oil, and it is better for you. It is derived from fresh fish, and there are no preservatives used when it is processed. If you would like to add fish oil to your diet, you should use a pharmaceutical grade fish oil that will not be harmful to your body or your health. Be careful and really read the labels.
