Bottom line up front:

Generally no benefit in treating cancer.

Inconclusive evidence for heart health.

Probably does not improve blood pressure.

Probably does not help with muscle cramps from statins.

Possibly effective for treating migraines

 

What is it?

Coenzyme Q10 is a fat soluble compound that is created in the body and can consumed in food. Inside the body it helps in the creation of ATP which our body uses for energy.  It also works as an antioxidant protecting the body from oxidation damage. 

 

What does that mean?

CoQ10 is naturally created in out body because we need it to process energy stores in our body.  It is also used to prevent oxidation damage to our cells.  Since out bodies make it we generally do not have to replace it.

 

Why might you take it?

Lower blood pressure

Prevent side effects from statin medications

Possibly slow progression of Alzheimers

Improve heart conditions

Migraine headaches

 

How much can I take?

100 to 200 milligrams per day is the average

Some take up to 1200 milligrams per day

 

What happens if I don’t get enough?

Generally, your body makes enough on its own.

Taking extra is not required.

 

What happens if I take in too much?

Diarrhea

Heartburn

Nausea

May interact with blood thinner (warfarin) and diabetes medication (insulin)

 

What can I eat?

Tuna

Salmon

Mackerel

Vegetable oils

Spinach

Broccoli

Meats

 

Final take:

We often recommend this for patients with muscle aches from starting medications to reduce their cholesterol levels called statins.  Evidence does not exactly support that recommendation.  Generally, this is a safe supplement.  We naturally make it in our bodies but we are not sure that adding more is beneficial.  Even in situations where we might have lower levels of CoQ10 we are not sure replacing it leads to significant benefit.  If this helps you, you likely can continue to take it safely.
