FREQUENTLY ASKED QUESTIONS
What is NAC Drops?
NAC Drops is an opthalmic solution, it contains an eye-friendly anti-aging antioxidant (n-acetyl-carnosine), which can be used to help optimize overall eye health and vision.
Who are NAC Drops for?
NAC Drops are for anyone interested in benefiting their eye health and vision naturally.
Why not just take carnosine orally?
It is much more effective when applied topically rather than orally, as it is true with a lot of other compounds. From our own experience, we couldn't tell much difference in the optical state from oral l-carnosine supplementation, as in comparison to dramatic (and also instant) effects experienced from an eye drop form.
L-carnosine vs. N-acetyl-carnosine?
The NAC molecular structure is identical to carnosine with the exception that it carries an additional acetyl group. It is only n-acetyl-carnosine that has been clinically proven as suitable for eye use. When applied as eye drops l-carnosine cannot penetrate the eye.
Can I share NAC Drops with someone else?
Eye drops are meant for individual use and should never be shared. Doing so isn't hygienic, as individual microbiome varies enormously between people. Your personal NAC Drops bottle shouldn't be shared with anyone.
Do N.A.C. eye drops have side effects?
N-acetyl-carnosine eye drops (1%) have been tested in double-blind placebo-controlled studies (6 -24 months) with no adverse effects being reported and are considered to be very safe for long-term use.
Other than the temporarily eye redness, which is a normal reaction to N.A.C., they have been demonstrated to be free from any serious side effects.
What's wrong with preservatives in eye drops?
The most commonly used preservative in eye drops is benzalkonium chloride. This preservative can induce corneal and conjunctival cell death, damage the corneal nerves, delay corneal wound healing and interfere with tear film stability. It's especially toxic to human cells and is the first one to avoid.
Preservatives and chemicals ordinarily used in eye drops can make dry eye symptoms worse.
Will this help my chronic dry eye?
Antioxidants decrease dry eye symptoms and although the factors that lead to DED are often complex you can expect improvements by addressing free radical damage, as that is most certainly one of those factors.
What about ocular autoimmune disease?
Your eyes will benefit from the drops especially when in a severely antioxidant deficient state, including situations when there is a lower expression of antioxidant enzymes, like in the eyes with Sjogren's syndrome.
Are the drops good for cataracts?
N-acetyl-carnosine first became popular for its use in eye drops as a cataract remedy, we do not however promote our product as such. The drops are meant to help positively affect eye health and can be used to universally benefit any ocular condition, including this of cataracts. Nevertheless we don't recommended our drops as an alternative to medical treatment of cataracts.
Do they change eye color?
NAC Drops won't change your eye color, although the antioxidant effect can make eyes appear slightly brighter.

Our drops don't contain any artificial vasoconstrictors, only an antioxidant that helps reduce inflammation naturally.
