What I am currently using is Barley Life--a MLM product. I have also used Barley Max from Hacres.com. When I first started using it, I was taking the maximum dosage of aspirin (this was in 1991) for arthritis in my hands. Within two days of starting, the pain was 75% better and was completely gone in 10 days. The deformity to my knuckles has not improved, but I have remained pain-free unless I miss taking my daily drink of Barley.
I take a lot of supplements, but this is the last one I would be willing to give up. As for the taste, you can learn to like anything if you hurt enough.
I use this product that you might want to try sometime. It has Barley grass in it but it tastes pretty good too. I used it during a 21 day detox last summer and it seemed pretty good. I had lots of energy. Usually I mix it with Bolthouse Berry Juice. They have the Berry Greens that tastes the best and then the Greens 8000.
