The clearest eyes

Clarifye NAC Eye Drops

NAC Drops solution support eye health by diffusing a powerful but natural anti-oxidant directly into your dog’s eyes.

We believe that antioxidant eye support is a breakthrough in providing natural support for your dog’s eye health.

NAC Drops offer excellent soothing and lubricating qualities. N-acetyl-carnosine  has been found to be safe in both human and animal trials. You can use Clarifye NAC drops to support your dog’s eyes naturally.

From £18.72/10ml incl. VAT


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

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  1% (lubricant), Hypromellose 1.0% (lubricant), 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.

Don’t just take our word for it….
