For Dietary Supplementation "I purchased HEB's CoQ-10 100 mg soft gels. I noticed I was feeling jittery and nervous and was not able to sleep most of the night. At first, I didn't think it was the CoQ10 that was making me feel that way. The next day, I took it again, just one pill 100 mg, and I happened to have a doctor's appointment on the same day where they found my blood pressure was 148/76. I've never had blood pressure that high, in fact, I usually run a low blood pressure of around 100/66 or so. When I went home, I realized it must have been the CoQ10 after looking up in Google, some side effects other people were having were similar to mine. I stopped taking it, and the next day my blood pressure was back to normal. In the meantime, my doctor wants me to check my blood pressure twice a day for a whole month and see her again to see if I am developing hypertension."

For Dietary Supplementation "CoQ10 was recommended by a holistic health doctor who told me to take 200 mg. I am 69 years old and have always been sensitive to meds and some supplements, so I started with 50 mg of Blue Bonnet Ubiquinol. It seemed to give me some energy the first two days and lowered my blood pressure the first day (a good benefit), so I upped the dose to 100 mg. I then started getting a restless feeling and some anxiety. This is the second day on 100 mg, and it put me on the couch all day. My heart rate was high after I took it, got bad anxiety, and felt weak and fatigued. According to the Mayo Clinic website, these can all be side effects, so I will discontinue this. However, be forewarned that I read the half-life on this is 33 hours, meaning that in 33 hours, half the supplement is still in your body, and it can take up to 5 days to clear out."
