The gut microflora is now recognized as an important factor in overall health, with potential roles ranging from cellular and immune health to metabolic function and weight management. Studies indicate that obese individuals possess lower levels of Bacteroidetes microorganisms and higher levels of Firmicutes bacteria in the GI tract compared to lean individuals. In one study, germ-free mice inoculated with bacteria from obese mice showed increased Firmicutes bacteria and an increase in body fat over two weeks despite no change in dietary intake, compared to mice inoculated with bacteria from lean mice. In a double-blind, randomized, placebo-controlled study, 32 healthy adult subjects were given 1.4 grams or 2.8 grams of PreticX™ XOS for eight weeks. The Bifidobacterium count increased 21% from the baseline at four weeks and 17% from the baseline at eight weeks in the highest dose group. B. fragilis levels (a Bacteroidetes organism) were also found to increase. Similar results were found in another study involving healthy young women, which also showed PreticX supplementation resulted in an increase in fecal triglyceride and cholesterol concentrations. In contrast to many common prebiotics, these studies reported no gas, bloating or other intestinal side effects. Each serving of PureLean® Fiber provides 0.7 grams PreticX XOS and a minimum of 6 grams fiber, typically providing 3.5 grams soluble fiber from glucomannan, guar gum, apple pectin and prune fiber, and 3 grams insoluble fiber from flax seed and cellulose. Soluble fiber helps slow the rate of digestion, promoting satiety, digestive health, nutrient absorption and healthy glycemic control. It enhances satiety by absorbing water and adding bulk in the digestive tract. Research has revealed that the high molecular weight and viscosity of glucomannan is particularly supportive. Each serving of PureLean® Fiber contains 1 gram of glucomannan. Several randomized controlled trials indicate that glucomannan supports healthy weight management and lipid metabolism, and promotes healthy glycemic control.*


Take 1 serving, 1-4 times daily, mixed with a beverage. Adequate water intake is recommended.

In contrast to many common prebiotics, studies on PreticX™ XOS report no gas, bloating or other intestinal side effects. However, for some individuals, a rapid change in fiber consumption can cause gastrointestinal discomfort, including bloating, flatulence, abdominal pain or diarrhea. Additionally, when consumed without adequate fluids, fiber can cause G.I. obstruction. It is recommended to begin taking small amounts with adequate fluids and increase daily fiber intake slowly over time. If pregnant or lactating, consult your physician before taking this product.

Fibers in this formula could alter the absorption of some medications. Concurrent administration is not recommended. Individuals on antidiabetes medications may require blood glucose monitoring. Flaxseed may be contraindicated with certain blood thinning medications. Consult your physician for more information.
