It's fairly clear that CoQ10 is not the universal cure-all or fountain of youth that it is sometimes claimed to be. However, research indicates that it seems to be effective for several different uses, although further research is necessary to confirm such findings (see Does CoQ10 Work?).
Much more research is necessary before the safest and most effective dosage of CoQ10 can be determined. In addition, there is some speculation that different forms may be absorbed more easily than others.

CoQ10 is usually tolerated quite well, although it can sometimes cause side effects, such as:

CoQ10 can potentially interact with a few different medications (see CoQ10 Drug Interactions).
Reasonable doses are probably safe for most people, especially if high-quality supplements are used, because these supplements are less likely to be contaminated or have other problems. Some people are more likely than others to experience problems. Therefore, you should talk with your healthcare provider prior to taking CoQ10 if you have:
- High blood pressure (hypertension)
- Low blood pressure (hypotension)
- Any chronic health condition
- Any allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant (see CoQ10 and Pregnancy)
- Breastfeeding (see CoQ10 and Breastfeeding).
Make sure to tell your healthcare provider about any medications you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
