Our verdict

A single-ingredient glucomannan fiber powder in a large bottle with many servings. The listing gives no serving size or mixing directions, and its form fields conflict.

Overview

A pantry shelf of bulk supplements is where this Nutricost glucomannan powder belongs, sold in a bottle as a plain unflavored powder. Glucomannan is a soluble, bulk-forming fiber derived from the konjac root.

The reason to consider it is the single ingredient and the large number of servings in one bottle. The limitation is the muddled data, since the dosage form field says capsule and the use field says laboratory.

Who it's for

A supplement user who mixes their own fiber and wants a vegan, gluten free, non-GMO powder with nothing else added. Shoppers who prefer capsules, or who need clear dosing guidance on the page, should look at a different Nutricost listing.

Pros and cons

Pros
  • Gluten free and non-GMO
  • Many servings per bottle
Cons
  • Serving size not listed
  • Form fields conflict
  • Mixing directions absent

Performance notes

Glucomannan is a soluble, bulk-forming fiber, which means it absorbs liquid and swells, so how it is mixed and how much water goes with it matters. The listing gives neither, so the label directions are the only guide. Being unflavored, it takes on the taste of whatever it is mixed into.
