This is where an insoluble fiber supplement can be useful.

  • Supports regular bowel function and helps relieve occasional constipation, without any harsh fibers such as psyllium

Cons

  • May clump when mixed with liquid
  • Unflavored taste may be unappealing to some
  • Some customers have reported difficulties with dissolving the powder

It can be blended into our morning shake or a glass of water, and I like that it doesn’t have any sugars or artificial flavors.

What is necessary to remember is that after adding the powder to the liquid, it may form lumps so it’s better to stir the mixture or use a blender. Thirdly, the fact that it has no flavor makes it less palatable, however, it can easily be mixed with other products such as a smoothie or juice.

Also, the presence of both soluble and insoluble fiber indicates that with this product you have both kinds of fiber in your diet.

But, we noticed that after taking the capsules, we started experiencing some level of bloating and formation of gases within the first few days of usage. This is a common side effect of taking fiber supplements or generally increasing the amount of fiber you ingest in your diet.

We also discovered that the capsules are relatively large which can be problematic for some individuals when taking. It might not be very suitable for people who find it difficult to swallow pills.
