### Common questions

#### Does your CoQ10 contain piperine?

Yes. Both our CoQ10 products contain 5 mg of black pepper extract, standardised to 95% piperine, which supports absorption. Please check the ingredient label for full details.

#### Is ubiquinol better absorbed than regular CoQ10?

Ubiquinol is the reduced form of CoQ10 and is generally considered more bioavailable than ubiquinone. Our CoQ10 provides 100 mg of ubiquinol per serving.

#### What are the benefits of taking CoQ10?

CoQ10 supports mitochondrial energy production and provides antioxidant activity, with potential benefits for cellular energy and heart health. We combine ubiquinol CoQ10 with piperine-rich black pepper extract.

#### What should I look for in a CoQ10 supplement?

Look for the form and dose of CoQ10, product quality and ingredients that support absorption. We combine 100 mg ubiquinol with piperine-rich black pepper extract for an absorption-focused formulation.

#### Where can I buy CoQ10?

CoQ10 is available on [decodeage.com](https://decodeage.com/products/coq10?utm_source=help_centre). Purchasing directly from us ensures that you receive a genuine product.

#### How do I take CoQ10 (Ubiquinol)?

Take one capsule daily after breakfast, ideally with fat-containing food such as ghee, butter or flaxseed oil. A bottle of 60 capsules lasts 60 days. The capsules are vegetarian.

#### What is the difference between CoQ10 and CoQ10 + PQQ?

Both give 100 mg of ubiquinol (the active form of CoQ10) with black pepper extract, one capsule a day after breakfast. CoQ10 + PQQ adds 20 mg of PQQ and natural vitamin E and uses Kaneka Ubiquinol®; it comes in 30 capsules, while CoQ10 comes in 60.

#### Can I take CoQ10 if I take warfarin?

Not without speaking to your prescribing doctor first, because CoQ10 may reduce the anticoagulant effect of warfarin and affect how well the medicine works. This applies to both our CoQ10 and CoQ10 + PQQ.

#### Can I take CoQ10 with blood pressure or diabetes medicines?

Only under medical guidance. CoQ10 may influence blood pressure and blood glucose levels in some people, so anyone taking blood pressure medicines, insulin or other diabetes medication should use it only with their doctor's advice.

#### Can I take CoQ10 while on statins?

Please consult your doctor first: statins can influence the pathway the body uses to make CoQ10, and research on taking CoQ10 alongside them remains mixed. Do not stop, reduce or change a statin prescription without speaking to your doctor.

#### Does the black pepper extract in CoQ10 affect medicines?

It may, as piperine can affect how certain medicines are absorbed or processed. Both our CoQ10 and CoQ10 + PQQ contain 5 mg black pepper extract standardised to 95% piperine. If you take regular prescription medication, ask a doctor or pharmacist whether the product suits you.

#### Does CoQ10 have any side effects?

CoQ10 is generally well tolerated when used as directed, though responses vary. Mild effects can include nausea, stomach discomfort, diarrhoea, reduced appetite, headache, or difficulty sleeping if taken late in the day. Taking the capsule after food may help reduce digestive discomfort.

#### Should I take CoQ10 with food?

Yes. CoQ10 is fat-soluble, so it is generally better absorbed with a meal containing some fat, such as eggs, yoghurt, nuts, avocado, olive oil or ghee. Taking it after food may also help digestive comfort.

#### What is Kaneka Ubiquinol?

Kaneka Ubiquinol is a Japanese-sourced ubiquinol, the reduced form of CoQ10 that is already in the active antioxidant form, selected for its stability, purity and bioavailability. Our CoQ10 + PQQ uses Kaneka Ubiquinol; take 1 capsule daily after breakfast.
