Did you know The protein content of bee pollen ranges from 10 to 35 percent (according to its plant origin), with a mean average of 20 percent. Forty to fifty percent of this may be in the form of free amino acids. All pollens contain the exact same number of 22 amino acids, yet different species produce varying amounts. This equals from 5 to 7 times the amino acids and found in equal weights of beef, milk, eggs or cheese.
