Vitamin A/E (Retinol/Tocopherol) HPLC

Vitamin A (Retinol) and vitamin E (tocopherol) are fat-soluble vitamins, which can be
stored for longer periods in the adipose tissue. Both, lack and excess, can express in
complaints.
Vitamin A is essential for the visual process and recovers the skin and mucosa. A lack
of vitamin A will reduce the visual power up to total blindness. An excess of vitamin
A could cause headache, damage of the skin, liver disease, painful alteration in
the skeleton or foetal damage.
Vitamin E (tocopherol) is an antioxidant and protects unsaturated fatty acids against
oxidation. It also protects the cells of the body by catching radicals.
A lack of vitamin E in animal experiments demonstrates diseases of muscle, nervous
system, heart, liver and reproduction system. These symptoms were not observed in
humans. Vitamin E can be stored in the adipose tissue in large amounts. A lack can be
caused by a malfunction in digestion or resorption of fatty acids.
