Hi

Welcome to just answer.com

lutein and zeaxanthines are two types of carotenoides which are found in leafy vegetables and colourful fruits. Theses are found very helpful to prevent macular degeneration and cataract. Moreover they also have anti-oxidant properties which protect our body from damaging effects of free radicals.

Studies have proved that acceptable daily intake for anti-oxidants is 2 mg / kg body weight which means for a person weighing 60 kg, the maximum dose would be 120 mg which is way more than which you mentioned in your question. Link for reference is: http://www.nutraingredients.com/Regulation-Policy/Scientific-panel-approves-safety-of-high-dose-lutein-zeaxanthin,

Recommended daily allowance for vitamin A for adults is 3000 IU per day. In case of deficiency states,Vitamin A is used in daily doses of 100,000 IU per day for 3 days followed by 50,000 IU per day for 2 weeks by mouth.

If you have any further queries, you are welcome.
