Years ago I bought a probiotic that helped me get over the end of glandular fever and helped with Delhi belly. It was quite pricey (£40!) but worth it. It was a green powder that you mix with water or apple juice, taken twice a day. It tasted like grass.
I can't for the life of me remember where I got it (mail order perhaps). Does anybody know of this? Or even something similar. My mum is going into hospital soon and she is very run down. I'd like to give it to her before she goes in.
