I take this pill everyday. It greatly improves everything including my focus and energy. I can't say enough about fish oil. My younger sister was 4 years old when she started to have seizures. She had them every week for a few years and every doctor just said she had to live with it but then someone suggested fish oil and after taking it every day she never had another seizure again. It has been 10 years since her last seizure and what doctors called chronic epilepsy was healed by a simple organic nutritional supplement. That to me was more than enough proof of what a miracle it is.
