I tried Krill oil today and my temp is up to 100.7 soon after. Normally it's about 99.3 to 99.5. It does go above 100 but usually that only happens at night and. I did a search on fish oil and fevers and several sites say stop taking fish oil if you get a fever so it obviously isn't something unheard of. I'm just wondering how fish oil could cause a fever, what mechanism is causing it? I have no problem eating fish or other seafood. I'll probably try it once more at some point before assuming it's related to the krill oil. Thanks.
