• About 95 million individuals all over the world are affected by glaucoma.
• Previous research present that consuming sure vitamins could assist decrease your glaucoma threat.
• Researchers have been investigating how a kind of vitamin B3 known as nicotinamide may assist decrease glaucoma threat.
• A brand new examine discovered that nicotinamide could assist decrease the danger of major open-angle glaucoma (POAG) in individuals with ocular hypertension.

Researchers estimate that about 95 million people all over the world are affected by glaucoma, a bunch of eye illnesses that may trigger harm to the optic nerve, probably resulting in imaginative and prescient loss.

Moreover, researchers have been investigating how a kind of vitamin B3 known as nicotinamide may assist decrease glaucoma threat as properly.

For this examine, researchers analyzed digital medical document information from 67 United States healthcare organizations, encompassing about 2,900 individuals with ocular hypertension however had not but acquired a glaucoma prognosis.

Half of the participant group acquired nicotinamide supplementation, whereas the opposite management group didn’t.

After a mean of three.7 years, 51 contributors of the nicotinamide group acquired a prognosis of POAG, in comparison with 132 contributors within the management group.

Whereas this isn’t thefirst examine to have a look at nicotinamide and glaucoma threat, there are nonetheless questions relating to the protection of nicotinamide supplementation.

In March 2025, the American Glaucoma Society and the American Academy of Ophthalmology issued a joint statement relating to the protection of nicotinamide supplementation, as taking an excessive amount of of nicotinamide can result in liver harm.

Based on the joint assertion, ongoing scientific trials are utilizing what are thought-about excessive doses of nicotinamide at 3 grams (g) per day. Typical nicotinamide dosage is much lower, between 500 milligrams (mg) to 1,500 mg per day.

Potential adverse effects of taking an excessive amount of nicotinamide embody gastrointestinal points equivalent to nausea and abdomen ache, complications, dizziness, and fatigue, and has the potential for extra extreme threat together with liver toxicity, elevated blood sugar ranges, and blood issues.

Medical Information Immediately spoke with Benjamin Bert, MD, a board-certified ophthalmologist at MemorialCare Orange Coast Medical Middle in Fountain Valley, CA — who was not concerned on this examine — about these analysis findings.

Bert commented that whereas this examine additional helps that nicotinamide could also be protecting in regard to the event of glaucoma in excessive threat people, earlier than beginning any new dietary supplements, it is very important focus on them together with your doctor.

“Even when a remedy doesn’t require a prescription, there are nonetheless dangers concerned, together with interactions with different drugs or dietary supplements that you’re taking,” he defined. “With nicotinamide there could be liver toxicities at larger doses, so liver operate exams could have to be monitored if you’re utilizing a better dose.”

Ariana Levin, MD, an assistant professor within the Division of Ophthalmology at NYU Grossman College of Drugs — who was likewise not concerned on this examine — agreed.

“I like to recommend that sufferers who wish to take dietary supplements ought to focus on these with their major care doctor to make sure they’re taking a dose that’s cheap to take together with the remainder of their prescription drugs and within the context of their common well being,” Levin defined to MNT.

“Usually, dietary supplements aren’t regulated in the identical approach prescription drugs are, so sufferers have to be diligent in evaluating the product that they’re shopping for from the shelf (or on-line),” she suggested.

Since glaucoma causes irreversible harm, Levin mentioned that discovering new methods or stopping the illness is essential.

“Ideally we forestall harm from occurring earlier than a high-risk affected person develops the illness, or at the very least forestall additional harm whereas the illness continues to be gentle,” she detailed. “As soon as a affected person has glaucoma, they’ve that prognosis for all times. We will get glaucoma beneath management, nevertheless it isn’t a prognosis that ‘goes away’.”

“This text is thrilling as a result of it focuses on early prevention,” Levin continued. “It additionally focuses on a possible remedy that doesn’t act by reducing eye pressure. Reducing eye stress is a very powerful device we’ve proper now in treating glaucoma, however we want different instruments as properly.”

As glaucoma is a blinding illness, Bert mentioned any remedies that we will have to stop the event, forestall the development, or scale back the general threat are extremely useful.

“A remedy that enables our our bodies to proceed to operate the best way that they’re alleged to, as is the speculation with vitamin B3, then that will be particularly useful. Glaucoma could be a troublesome illness to manage, so it is crucial that analysis continues to have a look at it from many alternative features to assist proceed to develop new remedies.”

For the subsequent steps on this analysis, Bert mentioned the most important piece of knowledge lacking from this examine was the dosage of nicotinamide that the examine inhabitants was taking.

“The examine categorized people who had been taking any supplementation of vitamin B3 as having ‘publicity’ to nicotinamide,” he defined. “Thus, it will be extremely useful to have further research discover the precise dosing that will be useful. Figuring out a selected dosage would additionally permit for the suitable suggestions for monitoring potential unintended effects.”
