FAQ: Does flaxseed contain protein?



Flaxseed is a great source of plant-based protein. The protein found in flaxseed is very similar to that of soybean protein, which is considered one of the most nutritious plant proteins.  This is attributed to the type of amino acids present, which are the building blocks of protein. Flaxseed contains numerous “essential amino acids”, which the body cannot produce and therefore must obtain from the diet.  This is of significance to vegetarians relying on plant sources to meet their daily protein requirements.
