I’ve been using Ubiquinol for years and believe it has contributed to helping my dog be a healthy 15 year old JRT. I do think the dispenser pump is not working correctly. It gets clogged up and doesn’t dispense the product correctly. I use Bark & Whiskers Krill Oil, too, which comes in a dispenser like the Ubiquinol; however, I never have had a problem with the Krill Oil dispensing. The problem, as I have experienced it, is only with the Ubiquinol pump. I’ve been using it for years and this just started happening a little over a year ago. I keep buying it because I think it is a good product. I just wish they would re-engineer the way the product is dispensed.
