Colon Cleansing Club

From experience, the most effective Colon Cleanser Products are based on Psyllium.
Therefore, I made a list of the best available products which contain psyllium.

Now Foods offers the following colon cleanser products:
Psyllium Husk Caps, 500 mg, 500 Capsules
Psyllium Husk Powder, available in 340 or 680 grams
Psyllium Husk Fiber, Orange-Flavored
100% Certified Organic Whole Psyllium Husks, 12 oz (340 g)

Yerba Prima offers the following colon cleanser products:
Psyllium Whole Husks, Colon Cleanser, 12 oz (340 g)
Psyllium Husks Veg Caps, 625 mg, 180 Capsules

Health Plus Inc. offers the following colon cleanser products:
100% Pure Psyllium Husk, 24 oz (680 g) -> this is one of my choices!
The Original Colon Cleanse, Colon 1, 200 Capsules
The Original Colon Cleanse, Orange Flavored, 12 oz (340 g)

Frontier Natural Products offers the following colon cleanser products (also in image below):
Organic Whole Psyllium Husk, 16 oz (453 g)
Powdered Psyllium Husk, 16 oz (453 g) -> this is one of my choices!
Whole Psyllium Husk, 16 oz (453 g)
Organic Powdered Psyllium Husk, 16 oz (453 g)

There are also other Colon Cleansing Products out there on the market, but based on this list you know under which forms you will find the Psyllium and after testing a few, you will make your choice.
For example, even if the capsules are easier to take in, the most effective is the whole, organic, or powdered Psyllium Husk.
