Vitamin E. Polarised light micrograph (PLM) of spiky crystals of vitamin E (tocopherol). This is an essential vitamin for fertility and reproduction. Vitamin E is widely distributed in vegetable lipids and the body fat in animals; the richest sources are seed embryos and their oils, and green leaves. As tocopherol is widely distributed in the diet, vitamin E deficiency is rare. Magnification unknown.
