There are some juice cleanse threads on here, but most of them seem to be about weight loss.

Are there any juice cleanse, or juice strategies, that one would use exclusively for digestion, i.e. constipation?

There are so many companies, products, recipes out there. You can buy it from a company or try and blend them yourself for instance.

On the other hand, having a bottle of juice would be very convenient for me, it's a hassle to buy and prepare normal meals, so if it worked I would like it.
