In addition to carbohydrates, proteins and fats, our bodies need vitamins to function well. When Henrik Dam conducted experiments on chickens that were given food with a low fat content, he noted that they suffered from bleeding that took a long time to stop. In 1934 he showed that an addition of hempseed counteracted the bleeding and concluded that the seed contained a substance, vitamin K, that was needed for the blood to coagulate. This knowledge became especially important in treating bleeding among small children.
