Click on this link to Amazon.com at the bottom of the first post in the above thread. Then read the customer reviews to compare the brands that have the most favorable results. DO NOT use the juice! It contains way too much sugar. Perhaps you can find it locally in a vitamin & supplement store. I take two capsules a day at the beginning of a meal.
You could try opening a capsule and pouring the contents into a small glass of water. Stir it and see how it tastes. If you can take it that way, you would avoid all the sugar that's in the juice.
