Melrose's green thinness is mainly composed of organic barley grass, organic wheat grass, Chlorella, spirulina and so on. And it is rich in various vitamins and minerals. After eating for a while, I feel good. Moreover, melrose is certified by authoritative TGA and ACO in Australia, and the certified products are reviewed many times every year. If the quality is unqualified, it will be ordered to go off the market. Don't worry about safety!
