I heard that Magnesium glycinate, turmeric curcumen, Vitamin D might help. Any suggestions?
In a word: none. Eating a healthy diet and staying out of the sun has some effect, but that’s about it. Here’s what the National Eye Institute and Mt. Sinai have to say:
While there’s ongoing research about the effects of various supplements on cataract development, the results so far have been mixed and don’t support any specific recommendations, according to the National Eye Institute.
Eating fish may help prevent cataracts. In one study, researchers found that women who ate fish 3 times a week rather than once a month lowered their risk of cataracts by 11%.
There has been some study of antioxidants in the diet, too. In one study, researchers found that higher dietary intakes of lutein (found in green vegetables, egg yolks, squash, corn, grapes, and orange juice) and vitamin E from food and supplements significantly reduced the risk of cataracts during the 10-year study period. However, there is no proof that taking these nutrients in supplement form will help. In fact, one study found that high-dose vitamin C and high-dose vitamin E increased the risk of age-related cataracts.
In another study, people who ate more foods with protein, niacin, thiamin, riboflavin, and vitamin A had fewer cataracts than those who ate less of these nutrients. Niacin, thiamin, and riboflavin are B vitamins. Again, the study looked at people who got the nutrients through food. Researchers do not know whether taking any of these vitamins as a supplement would help reduce the risk of cataracts.
