It’s like nordic naturals. My mom used to give me cod liver oil when I was a baby...by the SPOONFUL!
If I take less than the 10,000 mg/day, I start to feel it in my joints, especially the hands. I believe it has helped me think clearly as well. My daughter swears by it. If she misses a day or so, her cognition slips, and she has trouble concentrating. I attribute her remarkable recovery from her very bad TBI, in large part, to very larges doses of fish oil immediately from being discharged from the hospital. In fact, she just had her third neuropsyc exam, and she scored extremely well. We are so thankful to God. She went from scoring "Impaired" in nearly all, if not all, areas when she was first tested in the hospital to scoring only mildly impaired in math (which isn't a surprize) and mildly impared in one other area-remembering lists of words). However, she scored in the "Superior" range for executive functioning which was where she was originally the weakest due to where her injury was the most severe (the two frontal lobes). Everything else was scored in various levels of "Average". She takes about 8,000 mg/day divided into 4,000 with breakfast and 4,000 dinner. I'm not saying this is the only thing that helped, but I think it had a lot to do with her recovery.
