Pollen is the male part of plant flowers that bees collect and use as protein food. Bees press against the plant's anther and sweep off the pollen stuck to the hairy body with their legs, forming pollen grains. In order not to spill them on the way to the hive, the bees add nectar and saliva, squeeze them into lumps with their jaws and place them in special baskets on their hind legs. The weight of the nub is on average 7.6 mg, and to collect 1 kilogram of pollen, bees have to fly out of the hive 45-67 thousand times. Pollen contains about 50 different components, and they contain all the substances necessary for the development of the human body: proteins, fats, carbohydrates, vitamins, minerals, enzymes, hormones. Pollen contains all essential amino acids and many others, about 30 in total. Most of the carbohydrates are glucose and fructose. Pollen is one of the richest products in terms of vitamins. A normal dose is 20 g (1 heaped tablespoon) of pollen per day. The dose can be increased if a person has an eating disorder, overwork, a weakened body, suffered severe illnesses and used large doses of medication. Pollen is especially recommended for children in the winter and spring season, when they run out of energy and there are no other natural vitamins. For 3-5-year-old children, the dose is approximately 12 g (1 heaped teaspoon) per day, and for 6-12-year-old children - 16 g (1 tablespoon) per day.
