Vitamin E (Alfa-tocopherol)
fS-E- Vit KL 3169

Vitamin E (alpha-tocopherol) is a vital fat-soluble vitamin and serves as one of the body’s primary antioxidants. Its crucial role involves shielding cell membrane components, particularly polyunsaturated fatty acids, from damage caused by radicals and oxidative stress. Additionally, vitamin E helps prevent the oxidation of LDL particles and offers protection against the toxicity of heavy metals in tissues.

Lower levels of vitamin E may indicate the presence of a fat malabsorption disorder. On the other hand, in cases of familial hypercholesterolemia, vitamin E concentrations are notably elevated.

It is worth noting that children and young individuals (under 19) generally have lower vitamin E levels compared to adults.
