Vitamin E Oil8025969
Vitamin E is described as the "lightening rod" of the cell, allowing reactive molecules to strike the cell with out damaging it. This is apparent in the case of skin, where vitamin E protects the skin from ultraviolet radiation. Vitamin E-rich foods, when taken, can directly travel to the skin cell membranes and shield the skin.
Vitamin E comes in the type of gels, capsules and oils. Oils and gels can be applied topically to help protect the skin and also for scars. Vitamin E consists of alpha-tocopherol, either 100 % pure or mixed. Alpha-tocopherol in its natural type is powdery and thick. Hence, it is mixed with a carrier like olive oil. Vitamin E oil is processed from vegetable oils like corn, soya and canola through vacuum distillation. It is heavy and viscous.
Vitamin E oil has a shelf life of about two to 3 years. When exposed to air, it reacts with oxygen and hence becomes inactive, resulting in a decreased shelf life and potency. Similarly, exposure to extreme heat also reduces the shelf life. As such, vitamin E oil ought to be stored below well-protected circumstances.
Usually, manufacturers of vitamin E oil add ingredients like glycerides, and consequently, vitamin E content may be in the variety of 18-20%. The IU value of the oil (International Units, one hundred IU is equal to 67 mg for natural vitamin E and 45 mg for synthetic) might differ from manufacturer to manufacturer, depending on the type of tocopherol present and the percent in the oil. For instance, oil processed from soya will be wealthy in gamma-tocopherol.
Synthetically created vitamin E oil comes in the type of esters of tocopherols, mostly acetates and succinates. The esters are much more resistant to oxidation throughout storage than unesterified tocopherols. These are primarily used in pharmaceutical formulations and meals formulations to fortify food. They are packed in soft gelatin capsules. The bioavailability of these esterified tocopherols is same as that of unesterified ones and is measured in IU.
