One tablet before lunch and dinner
Chew one cherry-blossom tablet 30 minutes before lunch and one before dinner. L-arabinose slows the enzyme that digests table sugar, and CQR-300® Cissus quadrangularis with white kidney bean works on the starch, so the rice, noodles and kueh you still eat leave less behind.
