Below is an approximation of this video’s audio content material. To see any graphs, charts, graphics, photographs, and quotes to which Dr. Greger could also be referring, watch the above video.

Glaucoma is now the main reason for irreversible imaginative and prescient loss on this planet. It’s attributable to the deterioration of the optic nerve that connects the attention to the mind. Most generally, this is because of extreme pressure contained in the eyeball. Ginkgo biloba is without doubt one of the most typical dietary supplements taken by glaucoma victims. It doesn’t appear to decrease intraocular pressure, however MRI research recommend ginkgo dietary supplements could enhance cerebral blood move within the mind.

What about blood move to the eyes? Ginkgo will increase ocular blood move in each regular and glaucomatous topics; so, it was put to the take a look at. Compared to sugar tablets, 40mg of a ginkgo extract twice a day, on high of their common anti-glaucoma drugs, appeared to considerably sluggish the development of visible defects in open angle glaucoma sufferers, the commonest kind––although it’s not clear on this examine if the individuals have been correctly randomized.

Aside from a single printed case report of visible enhancements after ginkgo supplementation, there don’t seem like different research on open angle glaucoma. But there have been two interventional trials on the much less widespread regular rigidity kind. They have been each randomized, double-blind, placebo-controlled crossover trials utilizing the identical dose and period. One discovered a big profit—an enchancment in pre-existing visible subject injury. But the opposite discovered no profit in any respect. If you wish to strive it regardless of the underwhelming outcomes, be sure to first focus on together with your healthcare skilled attributable to a attainable enhance in bleeding danger from the herb.

Any different complement prospects? In 2017, extraordinary outcomes have been reported in a number one scientific journal. Nicotinamide, a type of vitamin B3, was in a position to stop the event of glaucoma in aged mice susceptible to the illness, with greater than 90 % effectiveness. Moderate or extreme nerve injury was present in about two-thirds of the management mice, however 93 % of the mice given nicotinamide had none. The researchers concluded, “The degree of protection afforded by administering this single molecule is unprecedented and unanticipated.” A commentary on the examine printed within the New England Journal of Medicine entitled, “Nicking Glaucoma with Nicotinamide?” urged clinicals trials needs to be initiated.

The researchers thought to provide it a strive primarily based on the truth that glaucomatous mice had a comparable deficiency in NAD+ (for which nicotinamide is a precursor). Is that even the case in individuals? Apparently so. Those with glaucoma have a few third decrease nicotinamide ranges of their blood, in comparison with age-matched friends. And higher consumption of niacin, which is one other type of B3, is related to much less glaucoma. It was time to place it to the take a look at, and the title offers it away.

In 2020, a world workforce of researchers printed a examine wherein glaucoma sufferers have been randomized to nicotinamide or placebo for 12 weeks, and then switched for one other 12 weeks. And considerably fewer sufferers suffered additional visible subject deterioration whereas on the nicotinamide (4 %, versus 12 % whereas on placebo). A 2022 examine discovered important enchancment in visible operate in comparison with placebo inside two months, however shouldn’t be immediately comparable, since additionally they added pyruvate (which is one other vital element of vitality metabolism). For a dialogue of value, labeling confusion, and potential unwanted side effects of taking nicotinamide, take a look at the NAD chapter in my e book How Not to Age, wherein I am going by means of the professionals and cons of all 9 NAD-boosting dietary supplements—it’s like a tongue tornado: NA, NAM, NMN, NR, NAD, NADH, NMNH, NRH, and tryptophan.
