Interaction Details

There were no interactions found between Aspirin and Coenzyme Q10. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.

Pharmacist Analysis

Although CoQ10 is considered relatively safe for most individuals, it does have some reported interactions that are important to be aware of.

This includes:

  • Antihypertensives: Clinical research has shown that CoQ10 can significantly lower blood pressure but conflicting results have been reported.
  • Warfarin: Research is conflicting but concomitant use of CoQ10 and warfarin might reduce the anticoagulant effects of warfarin.
  • Alkylating Agents: Antioxidants such as CoQ10 might also protect tumor cells from chemotherapeutic agents that work by inducing oxidative stress, such as alkylating agents (e.g., cyclophosphamide) and radiation therapy.

Outside of the interactions I've listed above, CoQ10 is generally considered safe to supplement with in most situations.

In fact, some individuals taking certain medications (e.g., 'Statins') may be recommended to take it.

If you have any questions about CoQ10 supplements, be sure to speak to your healthcare professional. We are always happy to answer questions on the matter as well!

Safe With Aspirin?

While CoQ10 has been reported to potentially have interactions with the anticoagulant warfarin (which we've discussed on that particular interaction page), CoQ10 itself is not known to have any significant effects on blood coagulation.

In fact, there is some evidence to suggest that CoQ10 may have a potential role in reducing the risk of bleeding associated with aspirin therapy.

A randomized, double-blind, placebo-controlled trial published in the American Journal of Cardiology in 2014 noted the potential that CoQ10 supplementation has in reducing the risk of gastrointestinal bleeding in patients taking low-dose aspirin, although it wasn't specifically evaluated in this regard.

Overall, CoQ10 is considered safe to take with aspirin for most individuals, but it is important to talk to your doctor before starting any new medications or supplements.

Coenzyme Q10 Overview

Coenzyme Q10, also known as CoQ10, is a naturally occurring substance that is found in every cell of the body and plays an essential role in energy production within the mitochondria, which are the powerhouse of the cells. CoQ10 also acts as an antioxidant, protecting cells from damage caused by harmful free radicals. While CoQ10 is endogenous, meaning our body can produce it on its own, levels can decrease with age, with certain medications (e.g., statins) or due to certain medical conditions. In such cases, supplementation with CoQ10 may be beneficial. Additionally, CoQ10 supplements have been studied for a variety of health benefits, including improving heart health, reducing inflammation, and potentially even aiding in the treatment of neurological disorders such as Parkinson's disease. However, it's important to note that while some studies have shown potential benefits, the research on CoQ10 supplementation is still ongoing, and more studies are needed to fully understand its effects on the body.
