Can I take CoQ10 while pregnant or breastfeeding?

There is no sufficient evidence that suggests C0Q10 supplementation while breastfeeding is safe. We advise that you talk to your doctor if you have further concerns

How should I take CoQ10?

That is totally up to you. Some people find it most convenient to take all of their vitamins for the day together; others prefer to space them out. Some take them in the morning; some take them at night. Some take them with food; others don’t. Experiment and find what works best for you.

Will CoQ10 make me nauseous?

It’s possible, but unlikely. If they do, try taking them with food or before bed to lessen this effect.

How should I store my CoQ10?

For optimal results, CoQ10 capsules should be stored in a cool, dry place. Avoid placing your vitamins in areas with excess heat or moisture; these elements can start to deteriorate the product and reduce their potency. 


Does CoQ10 offer other health benefits besides supporting fertility?

Studies have shown CoQ10 levels to be lower in people with conditions such as heart disease. Therefore, some studies suggest CoQ10 may help lower blood pressure and support overall heart health, although more conclusive research is needed.

Is there any downside to taking CoQ10?

CoQ10 is generally considered safe for consumption, although it may lead to minor side effects such as an upset stomach, nausea, diarrhea, insomnia, heartburn, and headaches. You should always follow the instructions on your supplement bottle and speak with a healthcare provider before taking any dietary supplements or medications. Additionally, seek immediate medical care if you experience symptoms that could indicate an allergic reaction.

What to avoid when taking CoQ10?

When incorporating CoQ10 into your supplement regimen, it's essential to be mindful of potential interactions CoQ10 can have with other medications and vitamins. You should always consult with a healthcare provider before adding any new supplements to your diet. CoQ10 has the potential to interact with some blood thinners, insulin, and some types of cancer treatment. Understanding these precautions helps you make informed decisions about your supplementation

Are there any vitamins that should not be taken with CoQ10?

While CoQ10 is generally safe for most individuals, it’s important to be aware of potential interactions CoQ10 can have with other medications, vitamins, and supplements. Data show that CoQ10 may reduce the effectiveness of anticoagulants (blood thinners), and may not be compatible with insulin and some types of cancer treatment. Additionally, individual responses to CoQ10 can vary. Consult with your healthcare provider to ensure there are no adverse effects with specific vitamins or medications.

Yes, Q10 and CoQ10 are often used interchangeably to refer to the same compound. also known as CoQ, Ubiquinone, and Vitamin Q10.

How do you know if you need CoQ10?

Research suggests that CoQ10 may play a role in supporting reproductive health for both men and women. Supplementation with CoQ10 resulted in improvement to certain sperm parameters. Additionally, research has shown that high follicular CoQ10 levels were associated with higher pregnancy rates. Regardless of fertility concerns, a CoQ10 deficiency may cause symptoms such as fatigue and muscle weakness. It is important to note that CoQ10 deficiency is considered rare, especially in the United States (an estimated 1,500 people according to 2017 data). Specific health conditions, such as genetic mutations, diabetes, or cancer, are also associated with low CoQ10 levels. You should speak with your provider directly if you have questions about taking CoQ10.

Is it okay to take CoQ10 every day?

Research suggests that CoQ10 is safe to take daily for most people. While there is no established minimum or maximum effective dose, CoQ10 supplementation has been shown to be tolerated in doses as high as 1,200 mg/day. As a naturally occurring compound in the body, regular supplementation with CoQ10 can support cardiovascular health and energy production, and act as an antioxidant. It’s important to consult with your healthcare provider before making any changes to your daily supplement routine.
