First off man cannot digest celulose,grass fiber is undigstable.It will pass through you,but if you want to get your moneys worth out of your grass.Get a juicer which wont generate as much heat as a blender.I have a vitamax5000 blender and would never make a grass smoothie.Mainly because it would be the worst tasting smoothie on the planet!A juicer is an exellant investment in your health.Health assurance is far better than health insurance.Be well be green but keep it tasty!!
