Dr. Mercola Ubiquinol Liquid Dog & Cat Supplement, 1.6-oz bottle

Awesome, love Ubiquinol. Supports the longevity of my Maine Coon cat. Hes no longer a spring chicken, but through a good quality supp, can still run around, do yoga and be alert

my senior cat has been developing various health issues over the past 1-2 years, and recent tests showed some deficiencies. in addition to giving her calcitriol (active vitamin d) and b12 as advised by our vet, i've been adding more supplements to her treat rotation. so far so good, and this product seems to be one of the higher quality ones. it's unflavored, so she doesn't really seem to consider it a "treat" but it's very easy to administer and there was almost immediate improvement in her overall condition. will definitely buy again.

2 of my cats, both Russian Blue mix long-hairs crave this stuff like crazy; give them the max 2 pumps but they would probably lick the whole bottle if they could. Both have more energy and soft shiny coats. Both are older than my other 2 cats that don't really care for the ubiquinol which I think older cats and people need this in their diet.

It's hard to know if this is making a positive difference. I squirt it into the food syringe along with the food to administer or squirt it on a taurine tablet or treat, then dispense.

Could not use it. Cat is on a lot of medication. Too hard to get her to take it

One of my dogs has heart diseases so I started reading about CO-Q10. I had ordered some and when it came I realized that the strength was too much for my dog and I could not give her less easily. I did more reading and found out that Ubiquinone (which is what I had) is not as good as Ubiquinol (which is what this product is). I did some more looking and found this product which is Ubiquinol, easier to dose the right amount (why did I not check Chewy's first like I normally do??). I do one pump in her food morning and evening and that is it. I also give it to my 19 year old little min-pin as it is a safe supplement to give. I will be ordering this again.

Works well on 2 out of my 3 dogs with heart issues. Gives them more energy and appetite. One dog did have problems with agitation on it.

I use this in conjunction with the prescribed meds for my Doberman's heart failure condition. As stated by everyone else here, the pump works or it doesn't. When it doesn't, I carefully pour a few drops in his food. I believe this product is helping prolong the life of my buddy.

I love this product and feel like it has really helped with the health of my dog. I was originally frustrated with the pump not working properly. I have a work around that has worked 100% of the time when it acts up. Just keep a toothpick nearby and when it stops pumping, unscrew the lid and turn it upside down. Take the toothpick and dislodge the ball in the lid. You will hear it dislodge. Works every time and not that big of a deal. Worth if for the health benefits.

Now I know why this item was out of stock for so long – it was being shrunken from 1.9 ounces to 1.6, which might not sound like a lot but the bottle is conspicuously smaller -- though not the price, of course. I'm disappointed and will be buying a liquid form of ubiquinol made for humans from now on. Much more economical in the long run, I think. But Chewy's customer service is still the best in the business!
