A recent study had great results in preventing glaucoma or stopping the progress of glaucoma by supplementing the diet of mice with vitamin B3 (nicotinamide). But now the research needs to see if this also holds true for humans.
Glaucoma is a common neurodegenerative disease that results in vision loss. Two main risk factors are increasing age and high intraocular pressure (pressure in the eye). The researchers said that their next step is testing B3 in human glaucoma patients. So stay tuned...
Vitamin B3, also known as niacin, is an essential vitamin for health, but both deficiencies and too high doses have negative health effects. It is recommended that adults get between 14 mg to 18 mg of niacin per day. Since it is not stored in the body (the excess will be excreted in urine), then you need to get a continuous supply from your diet.
As seen in so many other studies of vitamins and minerals, there is no evidence of adverse effects from the consumption of naturally occurring niacin in foods, but one can get too much from supplements (along with negative health effects).
What foods are good sources of B3 (niacin)? Foods highest in B3 (niacin) are tuna, chicken, turkey, but other good sources are anchovies, salmon, sardines, red meat, peanuts, nuts, seeds, eggs, mushrooms, dairy foods. lentils, beans, potatoes, and grain products.
From Medical Xpress: Vitamin B3 prevents glaucoma in laboratory mice
In mice genetically predisposed to glaucoma, vitamin B3 added to drinking water is effective at preventing the disease, a research team led by Jackson Laboratory Professor and Howard Hughes Medical Investigator Simon W.M. John reports in the journal Science. ...continue reading "Vitamin B3 and Glaucoma"
