For cataracts, 20-50 milligrams of beta-carotene has been taken daily or every other day for 5-8 years.

For chemotherapy side effects, 250 milligrams beta-carotene has been taken by mouth daily for 21 days followed by 75 milligrams daily.

For mortality reduction, 1.2-50 milligrams of beta-carotene has been taken daily or on alternate days for 28 days to 14.1 years. Note: Some research has found an increased risk of death or cancer with beta-carotene supplementation.

For oral leukoplakia, 60-360 milligrams of beta-carotene has been taken by mouth daily or weekly for six months to one year.

For polymorphous light eruption, 75-180 milligrams of beta-carotene has been taken by mouth daily.
