Most fish oil consumers obtain just a fraction of an optimal dose because they only take what is shown on the bottles label. If you are taking a food grade quality fish oil you should take anywhere from 5-10 softgels of fish oil on a daily basis to achieve the best quantity.
Pharmaceutical grade fish oil products such as those from Doctor’s Holistic Rx contain a greater percentage of the omega 3 fats. You can take just 2 softgels of pharmaceutical grade fish oil on a daily basis to get the best quantity of the omega 3 fats.
