Dry, Itchy skin gone

My 68 year old mother started using Wheatgrass juice powder and Nutritional Yeast. Her skin is no longer itchy. We had to massage her with body moisturizer every 2nd day but now no more. Her scalp was dry and itchy. That problem is gone now. I'm still shocked. She started taking them in 2020 September. All thanks to your education Dr Berg.
