  • From this study (2 years ago):

  • Having taken CoQ10 (100mg), fish oil (1200mg; containing 360mg Omega-3) and Super B Complex (Nature Made, 460 tablets per bottle) daily, plus D3 (1000 IU) twice a week, for the past 70 days, I have been able to reduce my irregular heartbeat and day-time fatigue syndrome to almost nil, very effective indeed. I feel energetic throughout most days now. However, accompanying with the encouraging results, it comes with disturbing side effects:
    (1) Shallow sleeplessness/ Initial insomnia (awakening during the sleep; having more dreams now),
    (2) Often oversleeping, one to three hours, in the morning; often cannot get
    up after 8 hours' sleep.
    (3) Forgetfulness (light-degree memory loss),

    My/User’s physical data: Born in 1951; male; Asian-American; 60kg, weight; 163cm, ht.; associate professor in engineering; eating only white-meat regularly (avoiding red meat).

    My puzzle is: Why would CoQ10, and/or Fish Oil, have incurred such side effects that contradict to its/their intrinsic power/benefits?

    I have a history of low blood pressure. I have
    been taking coQ10 for about 9 months ( to lower cholesterol)in connection with Omega 3 and Vit D and occasionally vit B. I have noticed that I want to sleep a lot. I can slep for 12 hours. recently i dozed off while driving and totaled my car.
    I am 63 Female caucasian. Could this be a side effect of Co010

    Your encountering as you described could be the side effect of CoQ10 plus fish oil (omega-3), for it agrees with my experience.
    The side effect of CoQ10 accompanying Fish Oil seems not obvious or bothersome to me most of the time. But when it turns out to be obvious occasionally (once to three times a month; usually after a late sleep), I felt drowsy and tiresome.
    For example, about one hour after taking CoQ10, 100mg, with Fish Oil, 600mg, this morning, I first felt hyper or overexcited, then within another two hours, I started feeling a loss of energy (with a possible low-blood pressure or nearly faint symptom) and dozed on my chair for about 1.5 to 2 hours. I lost my appetite for lunch until around 4 p.m. and felt not energetic enough to swim in the afternoon, as so planned to this morning, so I skipped the swimming activity today.
    I am planning to take CoQ10 alone or at least further reduce the intake amount of fish oil (used to be 1,200mg each time) to 300mg each time if taken with CoQ10 to avoid such side effect. I have changed to taking CoQ10 every day but fish oil every other day (vs. every day too before) for three weeks, the side-effect frequency has reduced since then. The side effect usually occurred when both CoQ10 and fish oil were taken together after breakfast that day. – jc; July 26, 2012; Taiwan
