I did a quick Google search on DA, and here are the listed ingredients:
Glucomannan (natural soluble fiber), Di-Calcium Phosphate,
Hypromellose, Ganeden Lactobacillus Cultures,
Maltodextrin, Magnesium Stearate, Silicon Dioxide
Since DA appears to rely on soluble fiber and bascially yogurt cultures, you could probably achieve the same benefit through adding more fruit and veggies to your diet along with some yogurt.
