are N-acetylcarnosine (NAC) lubricating eye drops, sold by Zero Point Healers of Olympia, Washington. The advertiser describes them as “soothing lubricating eyedrops” that “support eyes’ natural healing process” in horses. Each box contains two 5 ml vials — roughly 75 drops per vial, based on applying 3 drops daily to each eye — and ships with a printed set of instructions.
Owners use Can-C™ as a daily ocular-support drop for horses whose eyes may be deficient in the natural antioxidant L-Carnosine. The company states it has sold Can-C™ eye drops for 20 years, offers free shipping within the USA, and places a tracking number on every order. To order, call toll-free (Robert answers the phone himself) or.
Note from InfoHorse: the statements below are the advertiser’s own and have not been evaluated by the FDA; they are not intended to diagnose, treat, cure or prevent any disease. If your horse has an eye condition, please consult your veterinarian.

According to the maker, Can-C™ is built around N-Acetyl-Carnosine (NAC) at 1% — a form of carnosine the company calls “a highly specific intraocular released form of carnosine which acts as both a stabilizer and carrier for safe delivery into the aqueous humor of the eye.” The advertiser explains that the healthy eye contains high levels of L-Carnosine, and that “the eyes of horses suffering from degenerative ocular diseases such as cataracts were found to be grossly deficient in this essential ocular antioxidant,” which Can-C™ is intended to replenish.
The full label lists active ingredients Glycerine (lubricant) 1% and Carboxymethylcellulose sodium (lubricant) 0.3%; sterile water as the ophthalmic-grade base (pH 6.7–6.9); N-Acetyl-Carnosine (NAC) 1% as the antioxidant; borate and potassium bicarbonate buffers; and purified benzyl alcohol as preservative. The NAC is described as patented by Innovative Vision Products and manufactured in a GMP-certified pharmaceutical facility.

Owners reach for Can-C™ as a daily, at-home way to support a horse’s eye health. The advertiser frames the drops around the eye’s own restorative ability: “One of the most amazing features of the eye is its ability to repair itself and prevent infection after injury. Can-C™ drops support the healing process by keeping the eye well lubricated and delivering essential nutrients to support the eyes’ natural healing process.”
For results, the company sets owner expectations of “initial results in only 3 months time” and “optimal results within 6–12 months” of consistent daily use. Because cloudy or changing eyes can signal a range of conditions, InfoHorse recommends pairing any eye-care routine with a veterinary exam so the right plan is chosen for your horse.
The advertiser’s dosing reference is 3 drops daily to each eye; each 5 ml vial holds about 75 drops, and every shipment includes a printed product insert with instructions for opening the tubes. The box pictures a human eye, but the company notes the drops are intended for use with horses as well as humans.
Can-C™ ships from Olympia, Washington. US orders arrive in about 2–4 days with free shipping; international orders run 7 days to 3 weeks, and customs duties may apply in some countries. To place an order or ask questions, owners can reach Robert directly at the company’s toll-free line or by email — a one-person, USA-based small business that has carried Can-C™ for two decades.
