Every question answered.

GlaucoProtect™ is a science-informed retinal and optic nerve support supplement. It combines 500 mg Nicotinamide and 120 mg standardized Ginkgo biloba extract — the dosages used in peer-reviewed randomized clinical trials — to promote neuroretinal protection, healthy eye circulation, and antioxidant defense.*

GlaucoProtect is for adults seeking to support healthy retinal and optic nerve function, healthy eye pressure balance, ocular blood flow, and antioxidant defense for long-term vision health. It is especially suited for those with high screen exposure or who are focused on maintaining visual performance over time. It is not a replacement for prescribed glaucoma therapy.*

Most eye vitamins are formulated around tradition or marketing. GlaucoProtect is formulated around evidence — every ingredient and every dosage reflects those used in published, peer-reviewed randomized clinical trials. Unlike proprietary blends with undisclosed quantities, GlaucoProtect discloses exact amounts and backs them with a Certificate of Analysis from internationally accredited third-party laboratories.*

The full evidence base — ten peer-reviewed studies including RCTs published in the British Journal of Ophthalmology, Clinical & Experimental Ophthalmology, Journal of Glaucoma, and others — is summarized on our homepage.

Each serving of two capsules delivers: 500 mg Nicotinamide and 120 mg Ginkgo biloba extract standardized to 24% flavone glycosides and 6% terpene lactones.

Each bottle contains 120 capsules. At the recommended dose of 2 capsules per day, one bottle provides a 60-day supply.

GlaucoProtect does not contain gluten, dairy, eggs, peanuts, soy, wheat, yeast, tree nuts. For full allergen information, please contact us.

GlaucoProtect’s formulation is grounded in ten peer-reviewed studies — four for Nicotinamide and six for Ginkgo biloba extract — including multiple randomized crossover clinical trials. Study findings include improved retinal function, improved inner retinal function measured by pattern electroretinography, improved quality of life after six months of supplementation, improved visual field performance and contrast sensitivity, and improved ocular blood flow.* Full citations are listed on our Science page.

Nicotinamide (Vitamin B3) replenishes NAD⁺ levels in retinal ganglion cells, restoring the metabolic fuel needed for mitochondrial function and axonal transport. It also repairs DNA damage and maintains cellular integrity under oxidative stress. The 500 mg dose was selected to match those used in randomized clinical trial published in Nutrients showing improvements in retinal function.*

Ginkgo biloba extract (standardized to 24% flavone glycosides and 6% terpene lactones) supports ocular circulation and provides antioxidant protection. Terpenoids inhibit Platelet-Activating Factor, improving blood flow and reducing vessel constriction to the optic nerve head. Flavonoids neutralize free radicals threatening retinal cell integrity. The 120 mg standardized dose reflects that used in clinical trials published in the Ophthalmology, Journal of Ocular Pharmacology and Therapeutics, Acta Ophthalmologica, and IOVS.*

Yes. Nicotinamide has been studied in four clinical trials. Ginkgo biloba extract has been studied in 6 clinical trials. Many of the studies used the same or comparable dosages as those in GlaucoProtect.*

Dietary supplements are typically taken consistently over time as part of a daily wellness routine. The clinical studies supporting GlaucoProtect’s ingredients were conducted over several months. Individual experiences vary.*

Active ingredients per serving (2 capsules): Nicotinamide 500 mg, Ginkgo biloba extract 120 mg (standardized to 24% flavone glycosides, 6% terpene lactones).

Yes. Every batch is tested by independent, internationally accredited laboratories including Eurofins Scientific, SGS, Intertek, and NSF International. Testing confirms: ingredient identity, exact amounts, absence of harmful microbes, and absence of heavy metals. A Certificate of Analysis documenting these results is available at glaucoprotect.com/coa.

A Certificate of Analysis is a document issued by an independent, accredited laboratory confirming that a product batch meets its specifications — verifying ingredient identity, potency, absence of harmful microbes, and absence of heavy metals. Your CoA for each batch of GlaucoProtect is available at glaucoprotect.com/coa.

Take 2 capsules once daily. GlaucoProtect can be taken at any time of day, with or without food. For best results, take it consistently as part of your daily routine — clinical studies supporting the ingredients were conducted over several months of consistent use.*

Either works. GlaucoProtect can be taken with or without food, at any time of day. Taking it with food may improve tolerability for those with a sensitive stomach.*

If you miss a dose, simply take it as soon as you remember. If it is nearly time for your next dose, skip the missed one and resume your regular schedule. Do not take a double dose. Consistent daily use over time is what matters most.*

No. Do not exceed the recommended serving of 2 capsules per day. The dosages in GlaucoProtect were selected to reflect those studied in clinical trials — not to be maximized. If you have questions about your specific situation, consult your healthcare provider.*

No. GlaucoProtect is a dietary supplement — it is not intended to replace any prescribed medications or treatments. Always continue your prescribed glaucoma therapy. Consult your ophthalmologist before adding any supplement to your regimen.

GlaucoProtect is generally well tolerated when used as directed. In some cases, mild effects such as stomach discomfort, headache, or slight changes in sleep may occur, particularly in sensitive individuals. These are usually temporary. If any unusual or persistent reaction occurs, stop use and consult a healthcare provider.

GlaucoProtect can generally be taken alongside other dietary supplements. Many users combine it with multivitamins, vitamin C, or omega-3 without issues. Avoid duplicating high-dose B vitamins in concurrent supplements. If you are taking anti-coagulants (blood thinners) or any prescription medications, consult your healthcare professional before use. Ginkgo biloba may interact with blood-thinning medications.

Consult a healthcare professional before taking GlaucoProtect if you have a medical condition or are taking any medications. This is especially important if you have a bleeding disorder, are scheduled for surgery, or have cardiovascular conditions.*

Do not take GlaucoProtect if you are pregnant or nursing. Consult a healthcare professional before use if you have a medical condition or are taking medications, including anti-coagulants (blood thinners). Stop use and consult a healthcare professional if any adverse reactions occur. Keep out of reach of children.
