Medication & Safety Cautions
Vitamin A
Vitamin A is required for normal vision and supports epithelial tissues. | The UL applies to preformed vitamin A, not beta-carotene from foods. | High preformed vitamin A intake can be especially concerning during pregnancy.
Zinc
Zinc supports immune function and numerous enzymes; it is also included in some eye-health supplement contexts. | Long-term high-dose zinc can interfere with copper status.
Vitamin E
Vitamin E functions as a fat-soluble antioxidant in cell membranes. | The DRI UL applies to synthetic vitamin E from supplements and fortified foods.
Omega-3 Fish Oil
Omega-3s are used in cell membranes and are often discussed in eye contexts, but supplement claims need outcome-specific evidence and bleeding-risk review at high doses. | blood thinners | bleeding risk | surgery
