Is My CoQ10 Expired? -- CoQ10 capsules in hand


While it's hard to know if covering that date was intentional or not, by listing only a date of manufacture, the manufacturer is avoiding a claim regarding shelf life. This is allowed -- since listing a Best By or expiration date is voluntary -- but it would be better to choose a product that lists a Best By date, as it represents that the manufacturer has stability data to back-up that date. Most supplements that are maintained properly (unopened, out of excessive heat and light) should be fine for at least 2 years. However, since it may take you a few months to use up the pills in your CoQ10 bottle, it would seem best for you to return it and ask for a more recently-manufactured product.

Regarding the sticker covering the manufacture date on your CoQ10: It's seems to me that possibly this was not an accident. Some time ago I bought a completely different product from Amazon, a package of 3M N-100 face masks Like your CoQ10, the manufacture date was covered by a sticker. After peeling of the sticker, I saw the date was SIX years earlier.

In checking with 3M, the manufacturer, these masks were guaranteed useful for only five years past manufacture. The manufacturers representative told me places like Amazon bought in large bulk and things could sit on the shelf for a long time. Five years seemed long to me. I returned the product to Amazon.

I have no financial interest in 3M or Amazon.

Glad you brought this up as I am certain this is common , although when selling masks unacceptable, with Amazon , Walmart, Home Depot and other big-box operations with huge inventories on big selling products. Right off the shelf , masks I bought at HD reveal their out-dated usefulness quickly as rubber bands break on the first use . Other products can sit months past best by dates and still function well. Even chocolate bars become discolored past a certain date .
