Product Information



Purified Psyllium Husk

For relief of occasional constipation (irregularity). This product generally produces bowel movements in 12 to 72 hours. Several days may be needed to establish regularity. Daily consumption of dietary fiber can offer many health benefits and plays a crucial role in promoting the health of the colon. Dietary fiber provides bulk, eases passage and helps to speed transit time through the digestive tract. It also aids in glucose absorption and may promote healthy cholesterol levels. Experts in the field of health and nutrition agree that adults should consume 25 to 35 grams of dietary fiber every day to maintain good health.

Quality Control Issue
I've had to return Colon Pure 3 or 4 times in the last 2 years. In that time, the texture and consistency of the psyllium is often extremely fine, like confectioners' sugar, which all but destroys the effectiveness of the product. I simply take the containers to my local GNC store and exchange until I have one that is back to the original coarse texture; then it is better than any other brand that I know of. Wake up GNC! You've had an edge on the competition; KEEP IT!

Works For Me
At a very healthy age 70, I need a little help with bulk and consistence. This is the only product that works properly for me. Life is good with this as long as I take it daily without fail.

I live in Australia and I always bulk buy this product when I’m in the USA, I’ve been using it for 15 years and swear by it. I use it in my breakfast shakes, bread making, and use it on my cereals . It’s the most effective product of its type I have ever used and highly recommend it.

Having been buying GNC's Colon Pure for so many years, I'd say at least 25, we can vouch that it's an excellent product. It's the only brand I've ever bought.

Unflavored psyllium
I'm pleased to have available unflavored psyllium. Doctors removed my colon completely and recommended using psyllium without citric acid, which is an irritant. Your GNC product dissolves relatively quickly in water. The only draw back is that it is more expensive than products with all the additives (sugar, flavoring, citric acid, etc.), which doesn't seem right!

Has this product change in the past couple of months?
A shopper on May 12, 2016
BEST ANSWER: There is a quality control issue with GNC's psyllium husk powder. In my opinion, it is most effective when the texture is coarse, but again in 2018 the product has been ground super fine, making it much less effective. It is possible that this is a supplier issue, and that GNC is just slow to address it.
Is this pure insoluble fiber?

can you take colon pure if you have diverticulitis?
A shopper on Mar 8, 2012
BEST ANSWER: Yes, you can take this if you have diverticulitis, however it may not be help. Psyllium based fiber (the fiber in this product) been shown to help with constipation, but not diverticulitis.
QUESTION FOR CUSTOMERS: Do any of you know of a different brand of psyllium husk powder that has more of a coarse consistency? GNC Colon Pure is now too finely ground to be effective.
Jack H on Nov 6, 2018
BEST ANSWER: I honestly haven't tried many other fiber products because I haven't needed to . I love colon pure and use it daily and don't feel the need to look any further.
