How much CoQ10 do you need per day?
There is no officially established daily dose of CoQ10 for healthy people. If you are considering supplementation, discuss it with your doctor, because the type of product makes a large difference in how much your body actually absorbs.
There is no official recommended daily amount for CoQ10. Unlike vitamins or minerals, no health authority has published an established standard for healthy people. The available studies mention CoQ10 as a possible supplement for specific conditions, but no study establishes a universal daily dose.
What the studies do show is that the required dose depends heavily on the type of product. At 120 mg per day, a soluble formulation reached approximately three times higher blood levels than a standard soft capsule. That difference is large enough to be practically relevant: someone taking a less bioavailable variant receives considerably less CoQ10 in the blood at the same dose.
For specific conditions such as migraine or COPD, CoQ10 is mentioned in the studies examined as a potentially interesting supplement, but even there no concrete dosages are recommended. Further research is consistently identified as necessary.
In short: if you are considering CoQ10, science offers no firm daily dose to go by. It makes more sense to discuss with your doctor or pharmacist whether there is a specific reason for supplementation, and which type of product is most suitable for that purpose.
