Choosing Vitamin E supplement for ageing
Vitamin E supplement is available in two forms: Natural and Synthetic. You can identify synthetic Vitamin as dl - alpha-tocopherol. The natural Vitamin E is d-alpha-tocopherol, or a blend of tocopherol such as d-alpha, d-beta, d-delta and d-gamma.
Synthetic Vitamin E is only half as beneficial as the natural Vitamin E.
Choose Natural Vitamin E supplement, note the first two letters, the synthetic vitamin E starts with 'dl', while the natural Vitamin E starts with 'd' alone.
Daily Intake Requirements
The Alliance for Aging Research recommends 100 to 400 IU per day. This requirement treats Vitamin E as an oxidant for the ageing. The RDA is only for 15 IU (male) and 12 IU (female). The RDA is based on avoiding Vitamin E deficiency. Some nutritionists suggest even higher levels such as 800 IU per day. I will suggest 200 IU of natural Vitamin E per day.
It is not easy to get more than 30 IU from food consumption alone.
It should be noted that cooking as well as freezing degrades Vitamin E very significantly.
