Konjac root is the source of one of nature's most beneficial soluble fibers--glucomannan. It can actually absorb and hold water up to 100 times its own weight! Konjac makes an excellent bulk-forming agent and may have a positive influence on blood sugar levels by delaying stomach emptying. These actions also promote healthy cholesterol levels, thereby supporting cardiovascular health. If you're looking for a konjac fiber supplement that's more than just bulk, try our Fiber Dense Glucomannan.It's 100% pure, 100% natural and 100% effective.
