Is CoQ10 Safe?
Before taking CoQ10, safety concerns should be discussed with your healthcare provider to minimize potential risks. For example, you should talk to your healthcare provider before taking CoQ10 if you have blood pressure problems, any chronic health condition, or any allergies. Also, CoQ10 supplements are not closely regulated, so it is important to buy a product that is made by a reputable manufacturer.
CoQ10 (coenzyme Q10) is a popular dietary supplement that is used for treating a variety of health conditions, as well as for promoting general health and youthfulness. 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
Make sure to tell your healthcare provider about any other medications you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Warnings and precautions to be aware of concerning the safety of CoQ10 include the following:
- CoQ10 is a dietary supplement and is, therefore, not as closely regulated as prescription and non-prescription drugs. Also, it can be marketed without any proof that it is either safe or effective. Do not assume that just because it is sold in the United States that it is automatically safe or effective.
Also, look for a CoQ10 product that is made by a reputable manufacturer. Your pharmacist is a good resource for information about which manufacturers are the most reputable. It is a good sign if a manufacturer abides by the rules of Good Manufacturing Practices (GMP) for drugs. It is also a good sign if a product has the United States Pharmacopoeia (USP) seal, which means that the product has been independently tested and shown to contain the correct ingredients in the amounts listed on the label.
- CoQ10 may cause a decrease in blood pressure. This could be a problem if you already have low blood pressure or if you take high blood pressure medication, because combining CoQ10 with blood pressure medications may increase the risk of low blood pressure.
- If you use or are planning to use CoQ10 for any specific health condition, make sure to let your healthcare provider know. Not only can your healthcare provider help you monitor your progress, but he or she may also be interested in any benefits or side effects you experience.
- CoQ10 can interact with some medications (see CoQ10 Drug Interactions).
- It is not known if CoQ10 supplements are safe for pregnant or breastfeeding women (see CoQ10 and Pregnancy and CoQ10 and Breastfeeding).
