I've tried high strength fish oils with approximately a 3:1 ratio of DHA to EPA and I took about 35 ml / day giving about 1.6g of Omega 3 / day. They had a benefit but the Krill oil seems to be working better. I'm now down to takingThanks Kurtosis. So you took approx 1.2g/day DHA + 400mg EPA which is not so far from 1.8g, without enough benefit to take it again I guess. I'll now have less placebo effect when I'll try it myself! I'll report, if it's effective. I'm at day 7 of taking a supplement containing (daily dose:300mg DHA + 2mg vit E + 1.5mg asthaxanthin, no EPA). I felt something positive before orgasm but not enough. No effect after orgasm, I still have POIS.
For the krill oil eventually it's not the Omega3 causing the good effect. Be sure to take a brand without hcb pesticides. You mentionned cod liver oil, it contains iodine and D.
I have minimal POIS symptoms anymore. I actually feel happy as I've been getting incrementally better since I started taking niacin and then figured out vit c would improve its effectiveness.Vit C gives me more energy too, but also anxiety so I can't take high doses. Nobody can tell me why, except a few articles of chinese medicine saying vitamin C is putting "cold in the kidneys", not very helpful. When I don't take vitamin C at all for 2-3 days, even from food, everything seems to go slowly, I feel very calm and libido is going up.
However, a key component for me is vitamin c. When I feel fatigued during the day I dissolve 1/2 gram of effervescent tablet in a small glass of water and it gives me a lift.
About iron, there are multi-vit without iron. Some studies noticed iron is linked with cancer but maybe it's ok taking low doses.
