It looks like a chocolate bar, but it isn't candy. It's sold in pharmacies, but kids love it. What is it? I'm talking about gematogen—a preventive medicinal product loved equally by children and their parents, sold almost exclusively in the CIS countries. Hematogen—primarily consumed by children, anemics or during pregnancy—is available without prescription and is used to prevent low blood levels and other deficiencies, treat problems with vision, improve skin, hair and nails. It is an excellent source of vitamin B12 and vitamin A, as well as protein, fats, carbohydrates and minerals, all present in quantities similar to the composition of human blood.*
