Are we talking about vit. A or E? Vitamin A has higher levels of acceptable limts than Vit. E. The reason is because Vit. A is not converted at efficiently as Vit. E. The recomended dietary allowance of Vit. A is 4000-5000 IU for adults. However, research seems to indicate that no more than 50,000 IU per day can be utilized by the body except in theraputic cases, where up to 100,000 IU of Vit. A have been used. There are those who suggest the best levels are in the 25,000 to 50,000 IU. If there is no vitamin deficiency, daily use of 50,000 UY may be toxic. dosages of 18,500 given daily for 1-3 months have also been reported as toxic for infants or those who have serious overall vitamin deficiencies. Vitamin C can help prevent the harmful side effect of high Vit. A. dosages.
As you can see, the acceptable dosages of Vit. A and E are very different. While doses of vit. E have been reported as high as 2000 IU, they are usually done within the context of a controlled situation and monitored by a medical professional.
Now, you left out a little (but important detail) in your first post... your having allergic reactions to Chlorine. What kind of reaction? Is is sinus related or is it skin irritation? Which leads me to next question. Were you referring to oral use of Vit. A and/or E? Or, were you asking about topical application of Vit. A and/or E?
If your referring to using Vit. A and/or E for a sinus reaction to chlorine, then I know of no research that indicates they will be useful. My solution to chlorine (sinus) allergy is call a nose clip. Simple, but effective.
If your having skin reactions to Chlorine then perhaps Vit. A and E may have a positive effect. Itching skin (and dry skin) are useally helped by topical versions of Unsaturated fatty acids. Typically, topical application of Vit. A and E are more tolerant of higher IU amounts.
