Conversely, a lower level of vitamin A and vitamin E is associated with Alzheimer’s disease. Sufferers have half the bloodlevels of vitamin E and beta-carotene of those people who do not have Alzheimer’s. Elderly people with lowbloodlevels of vitamin C have 11 times the risk of developing cataracts compared to those with high bloodlevels of vitamin C buy modafinil uk. Similarly, those with lowvitamin E blood levels have almost double the risk, while people consuming 400iu of vitamin E a day have half the risk of developing cataracts.

In relation to heart disease, supplementing vitamin E and vitamin C effectively halves the risk of ever having a heart attack — in a massive study on nurses, those who consumed 15-20mg per day of beta-carotene had a 40 per cent lower risk of a stroke and a 22 per cent lower risk of a heart attack than those consuming 6mg per day. Those with high dietary intakes of beta-carotene had half the risk of death from cardiovascular disease. Supplementing 1000mg of vitamin C also reduces blood pressure.23
