I have been taking 1g of fish oil for over 20 years (this year algae oil). I have ADD and both these oils measurably improve my concentration, mood, anxiety, impulsiveness, knee pain, menstrual symptoms, skin and sleep. No other supplement has given the promised benefits that fish oil has. I hadn’t read a whole book cover to cover until I started taking fish oil in my 20’s, and I am unable to get through a paragraph within 10 days of going off the oil. Study or no study, I can’t function without the stuff. Too bad it seems to be causing me exercise induced chest pain in my 40’s despite excellent fitness. I don’t like hearing that omega 3 sources are either rancid or toxic but I would rather risk shortening my life span with toxicity (the entire food chain is toxic at this point) than stress about concentration related errors at work, impulse related errors in relationships and finances, limited exercise due to knee pain, poor sleep, older looking skin, many good books gone unread, not to mention killer cramps. The reason I’m impulsively and randomly blurting this expression out there is because I have tried to go off the oil for just about a week and once again I am sorely reminded I can’t live without that oil. If I was taking it, I would have had a second thought about impulsively babbling like this and stopped myself from sending it. Now I’m late, another thing the oil helps with.
