I have no problems with the powder. It combines well with acerola (Vitamin C) mix, stir into yogurt and then taken as medicine. After a week of taking the joint symptoms have been better in the knee. It is important to take natural vitamin C in addition to the powder for biological conversion. The capsules can not mingle. Belching I have not even observed. Although the preparation does not taste good, but medicine to cure and does not taste good. If that's not enough to make sugar down as usual in children. Final evaluation: After completion of intake of the preparation of knee pain that has accompanied me for years is only reduced in extreme conditions to be felt. I'll post a longer break order the next pack and take. The preparation keeps more than I expected.
