Clarifye eye drops are used to keep your dog’s eyes healthy

Clarifye drops help to keep your dog’s eyes clear. The anti-oxidants in Clarifye help reduce damage to the proteins in the lens – keeping the lens clear

While there are many diseases that affect dog’s eyes, the most common long term problem is cataracts. They can be hereditary or created by lifestyle and diet. Diabetes is a common cause

Clarifye is for Dogs and Cats only – do not use on other species

You can use Clarifye on any age of dog, in a single eye that you feel needs support or on both eyes

Trustpilot rated 5 Star – see more reviews below

“The eye drops Clarifye have stopped the delevopment of cataracts in both of my Border Collies eyes”

Mr J Hall, Trustpilot Reviews, January 2020

Directions for Use

Suitable for both dogs and cats. Apply 1 drop in affected eyes 4 times a day. Continue application for at least 90 days for best results. A full course may need to be 6-9 months. Reduce the application to once per day when you feel that your dog’s eye health is satisfactory…………….watch this video if you need guidance on how to do it    

Take care not to touch the bottle tip to any surface or to the eye(s) when applying the eye drops -keep it sterile. Do not use Clarifye if your pet is using steroid eye drops as they would neutralise the Clarifye and it would not offer any  benefit.

Drops come in a 10ml bottle with a dropper dispensing system. Once opened keep re-sealed and cool and discard after 60 days. A  10ml bottle will give over 200 drops enough for both eyes for over a month. If you receive your product in damaged packaging please return it to us rather than using it.

Safety is our number one concern when it comes to eye support

It is safe for your pet to ingest and lick. Many diabetic dogs have eye problems and Clarifye is safe to use with diabetic dogs

Animal Clinical Research & Trials

The testing of various anti-glycation agents over nearly a  decade led a Russian research team to the development of n-acetylcarnosine as a delivery system for the natural eye anti-oxidant L-carnosine. These studies produced remarkably fast results for the animals involved. Furthermore, no serious side effects were noted and the beneficial affects were sustainable.

More recent studies by Cambridge University Veterinary School have confirmed that all 30 dogs in a trial received bebeficial effect from NAC eye drops. 


Clarifye contains more than twice as much N-acetycarnosine as other brands.

Ingredients – N-acetylcarnosine 2.2%(anti-oxidant), Glycerol, Modified Microcellulose, Hyalauronic acid (lubricants), MSM, Water (sterile purified), Boric Acid/Potassium Bicarbonate (buffer), Benzyl Alcohol (preservative)

All ingredients are pharmaceutical grade and the finished product is sterilised and hermetically packaged.

Great company very helpful and knowledgeable. After a long chat on the phone I placed an order just before Christmas and it arrived next day. My 2 labradors love the Flex sprinkle and are showing signs of the benefits by moving more freely. Just placed my second order.

You can't beat the best.
My little papillon has been on the Flex Jointcare for a number of years due to various life-long joint and ligament problems. Just recently it was really to prove its worth to me all over again! Buddy has been pretty poorly over a number of months and despite a CT scan nothing conclusive could be found. He was on pretty heavy drugs which I have now weaned him off and onto a natural oil. He was doing really well but then out of the blue started to show signs of distress! Realised that due to him not wanting to eat when he was poorly he had missed out on his Flex Sprinkle for nearly a month! Immediately started him back on a half dose to restart the routine he has been on for a number of years, and to which I have no doubts I owe the fact he is now approaching his 11th birthday and is still with me. Literally within 3 days my little Buddy started to perk up again, and now a week down the line and now back on his full dose of Flex Sprinkle, I have my adored bouncing Buddy back to his old self. I honestly cannot thank Ace-Canine enough for producing this miracle in a tub. I have recommended to so many friends, I have lost count.

Flex Sprinkle
I've used Ace-Canine's Flex Sprinkle for my Goldie for years; ensuring she stays as supple and mobile as possible.
From ordering to delivery, within 24 hrs!!! Excellent service.

Instant relief for our dog
Our 11 years old Keeshond started having joint issues and has an early stage of cataract. I contacted Ace Canine through their social media, asked for more information on which medication was best for our dog. Not only were they very helpful, I also got a discount code.
Our dog is relieving through her medication although if it's not given on time, she can relapse with fatigue and limping.
I've been giving her Clarifye for her cataract 4 times a day for a month, I think it helps but can't really tell for sure, also no changes on her eyes discolouration.
She's also taking Trimega as a multivitamin, Flex Celadrin and Flex Sprinkle Joincare. Now this combo has made a huge change on her overall health. She's back to being playful, even runs, seems more happy and has good appetite.
I used to give her as well Plaque Away, that definitely worked especially with foul breath but I stopped it as I didn't want to overload her with supplements.
All in all, would highly recommend Ace Canine products, it sure works on our dog.

Flex Sprinkle Jointcare
Love the stuff ! The dogs do really well on it rate it. The company staff really helpfully and delivered without delay. One of the best company’s I have dealt with

Flex Celadrin
I bought the Flex Celadrin capsules as one of my older dogs was suffering with his back legs. Have to say it seems to have made a great difference in his walking now. Much better to use this then the injection he was getting every 6 months. I will definitely continue to use these capsules. Thank you.

Flex Sprinkle Jointcare
Literally a miracle in a pot, our 16 year old staffy has a spring in his step and is moving about a lot more easier. Fantastic results, the loading dose has literally given him a new lease of life within 48 hours. We will be putting our 8 year old on it next. Amazing product that I wish we had known about sooner.

Excellent product - Clarifye. Has made an amazing improvement in my jack russells cataracts already even when she is 16 years old. It has given her a quality of life back and she is much happier in herself and enjoying her walks again. She can now see much longer distances and manages well in the dark.Product arrived promptly and well packaged. Thank you Ace Canine!!
