Can you please compare colostrum to chlorella and young barley?

It is an incomparable comparison to make. Young barley and chlorella are plants, therefore they contain vitamins, minerals and some proteins. Colostrum is of animal origin and besides protein, lactose, minerals and vitamins it contains immunoglobulins, which are most certainly absent in chlorella and barley. Colostrum also contains other important enzymes like lactorerrin (anti-cancer effects), lactoperoxidase (bactericidal and bacteriostatic effect), as well as many growth factors that are important for the regeneration of cells. The mechanisms of effects are therefore completely different. Barley and chlorella can be used as a source of vitamins and minerals and colostrum is used to support immunity.
