What to check before buying CoQ10
CoQ10 on a supplement label appears in the nutrient row of the Supplement Facts panel, and a common figure is 100 mg per softgel. The blend total on the front of the box is not that number. It is a sum of several ingredients, and it tells you almost nothing about any one of them.
Finding coq10 on a supplement label row by row
The top block is the serving size, and everything below it is what that serving contains. One softgel, or 2 capsules, or 3 tablets. That line sets the scale for every number underneath it.
Then the nutrients, each with a milligram or microgram figure and a percent daily value. CoQ10 usually shows a milligram amount without a daily value percentage, because it has no established reference intake, which is normal and not a red flag.
Then the other ingredients, in descending order by weight. Capsule material, oil, emulsifier, sometimes a preservative. These are not filler in the dismissive sense. They are what carries the nutrient and what your body meets first.
Why the blend total is the least useful line
A proprietary blend lists a single combined weight for several ingredients. If it says 400 mg of a 4 item blend, you don't know whether CoQ10 is 10 mg of that or 300 mg. The law allows this, and the effect is that the least informative figure on the label gets the biggest type.
I bought a blend product once because the front said 400 mg and I assumed that was the active amount. It wasn't. That's a $34 lesson and I've read the nutrient row first ever since.
What to write down before you buy
Four things. Milligrams of CoQ10 per serving. Number of softgels that serving requires. Capsules per bottle. Cost per day. At 100 mg per softgel, 1 softgel per serving, 120 softgels at $51.60, that is $0.43 a day, and now you can compare it with anything else on the shelf.
Ubiquinone is the common form and it needs fat to be handled well, which is why softgels and oil suspensions dominate. A dry tablet at the same milligram count is not automatically an equal swap, and the panel won't warn you about that either.
When a panel is vague, ask
If a product lists a blend without amounts, email the seller and ask for the per ingredient figures. A brand that knows its formula will send them. A brand that won't is telling you something about the formula, and that answer is worth more than the label was.
Partial disclosure is a partial claim. I've asked 3 times in 4 years and got a real answer twice, which is enough of a hit rate to keep asking.
Read the nutrient row, run the serving count, and ignore the biggest number on the box. It's the only part of the label written for you rather than for the shelf.
One panel I read last month
Softgel, 100 mg of ubiquinone in the nutrient row, serving size 1, 120 softgels, $51.60. The front of the box shouted about 3 other ingredients in a blend, and the nutrient row quietly carried the number I came for.
I wrote the 4 fields in my note, put the jar back on the shelf, and compared it against the 2 others in the aisle in under a minute. That is what the panel is for. It turns a shelf of claims into 3 comparable numbers.
Frequently asked questions
Which line has the useful figure?Show answerHide answer
The nutrient row inside Supplement Facts. The blend total on the front tells you far less.
Do I need to read the other ingredients?Show answerHide answer
Yes. Capsule material, flow agents and sweeteners are part of what you take.
What if a panel is vague?Show answerHide answer
Ask the seller for the amounts. A partial disclosure is a partial claim.
