Before I explain Nutritional Value of Pollen, lets explain what is Pollen. Most people hear of this word only in aspect of Pollen allergies, but there is far more to Pollen than just that!
Pollen is coarse powdery substance consisted of pollen grains which are male microgametophytes of seed plants. Pollen grains produce male gametes (sperm cells). Transfer of pollen to Pistel (female part of flowers) is known as Pollination. Pollination is done by wind as well as insects that are responsible for it. From all of the insects responsible for pollination, Honeybees do most of work. Honeybees are gathering Pollen from blossoms, stashing into small baskets on their legs and bring it to the hive. This is why, pollen is not product of Honeybees, but rather product of flowers, that’s harvested by bees. Honeybees mix Pollen with Honey to produce Beebread, which is main diet of all adult honeybees except Queen. Nevertheless, Honeybees commonly collect large quantities of pollen, which if not gathered by beekeeper can block Queen and be bad for entire colony.
Honeybees gather Pollen from blossoms of different trees and plants. Depending from source, different Pollen has different color, different nutritional value and different Health Benefits. Different Health Benefits will be explained in other article(s). Irrelevant from which blossom it comes, bee Pollen is Highly Nutritional and it is considered to be best source of vitamins from all of the food.

Even the Best Multivitamins are not better in nutritional values!
Pollen has strong protective membrane which can not be digested by humans. Best way to eat Pollen is to mix it with Honey, which will break that membrane and make it digestable by humans. If taken raw, you must chew pollen grains well, or if added into different fluids it should be grinded. Adults should consume 10-15g of Pollen daily, while in case of children that limit is significantly lesser. Children should take between 2-6g, and no more than it.
