Adults with retinitis pigmentosa (RP) should take 15,000 IU vitamin A supplement daily. Studies show’s vitamin ‘A’ supplement helps to slow down the progression of RP by 20%.

Another study shows adults with RP should avoid taking high doses of vitamin E supplements. It shows that the disease progress faster in patients on 400 IU vitamin E supplement daily.
Adults interested in vitamin A supplementation should first:
- Consult eye care professional regarding vitamin A supplementation.
- If people have liver disease or abnormally high level of vitamin A in blood, they will need to adjust their vitamin A intake.
- Take vitamin A palmitate instead of beta-carotene, because beta-carotene (natural precursor of vitamin A) breaks down differently by each person.
- Have balanced diet, without showing interest, especially in vitamin A.
- Avoid taking high dose of vitamin E supplements.
People will make a common mistake of thinking that vitamin A supplementation in excess (more than recommended 15,000 IU) will provide greater benefits. In excess of 25,000 IU of vitamin A, taken for a long time can be toxic and may cause liver disease.
