Nu Biome Review: Can Pink Powder Improve Gut Health?

Nu Biome Review: Can Pink Powder Improve Gut Health?

Read our Editorial Guidelines to learn more about what makes our site the premier resource for online health information.

Nu Biome is a powdered gut health supplement that’s mixed into water. It’s sold by a brand called Nu Skin that primarily sells skincare products, and is manufactured by a company called Pharmanex. The brand claims that Nu Biome “helps support…intestinal balance with a powerful dual action solution of pre- and postbiotics.”

But can a powder mix really support gut health or is it a waste of money? Are there any questionable additive ingredients? What are the active ingredients that Nu Biome suggests can improve gut health?

In this article we’ll answer these questions by reviewing every ingredient in Nu Biome based on medical research. Because Nu Biome contains a large number of ingredients, we’ll break our ingredient review into two sections: an active ingredient review and an inactive ingredient review.

Active Ingredient Review

Nu Biome active ingredients

Nu Biome contains the mineral chromium, and we are unable to locate any medical studies suggesting that this ingredient improves gut health. It also seems illogical in our opinion to take 286% of the Daily Value (DV) of a mineral without any documented deficiency of that mineral from lab testing. We’ll consider this ingredient ineffective.

While black coffee consumption may improve gut health, we can’t find any clinical trials suggesting that isolated caffeine does, so we’ll consider this ingredient ineffective.

The remaining active ingredients are included in a proprietary (“prop”) blend.

Xylooligosaccharides are an effective prebiotic ingredient backed by medical research, but may be underdosed in Nu Biome. A clinical trial published in the Gastroenterology Research and Practice journal found that xylooligosaccharide supplementation improved the balance of beneficial versus harmful bacterial strains in the gut of human subjects, but the dosage used was 1,200 milligrams (mg) per day.

The average ingredient dose in Nu Biome’s prop blend is only 403 mg, and we cannot locate any medical studies suggesting this dose is effective.

Pomegranate fruit extract was shown in an in vitro (test tube) trial to increase probiotic concentrations, but this is a weaker standard of evidence than a human trial. We cannot find any medical studies with human trial participants proving pomegranate fruit extract improves gut function, nor does Nu Skin cite any, so we’ll consider this ingredient likely ineffective.

The final active ingredient is Bifidobacterium animalis subsp. lactis which is a probiotic ingredient. Nu Skin fails to publish the specific strain of the probiotic which makes it impossible for consumers to evaluate its efficacy. Probiotics have a species, occasionally a subspecies (like in this case), and also a strain (example: Bifidobacterium animalis subsp. lactis BB-12). It’s also questionable that the colony-forming units (CFU) are not listed, because this is how the dose of probiotic ingredients is typically listed.

Overall we find this formulation to be highly underwhelming. We are unable to identify one active ingredient we would consider effectively dosed, and Nu Skin fails to publish information about the probiotic ingredient used which would help consumers assess its efficacy and make an informed purchase decision.

This supplement may be effective for gut health because it contains a probiotic ingredient, but without the dose in CFU and without the specific strain, we can’t say definitively.

Inactive Ingredient Review

Nu Biome inactive ingredients

Nu Biome contains two inactive ingredients we recommend avoiding.

The first is citric acid. This is a preservative and flavor enhancing ingredient that’s typically manufactured from a fungus called Aspergillus niger. As we documented in our Neocell Collagen reviews article, citric acid is shown to cause whole-body inflammatory reactions in a small subset of patients, which is why we recommend avoiding this ingredient unless the manufacturer specifies it’s derived from citrus fruits rather than a fungus.

Natural flavor is a broad term that refers to any number of chemical compounds used as flavoring agents. Medical research has shown that there are some legitimate toxicity concerns with some natural flavor ingredients, and while we consider natural flavor healthier than artificial flavor, we recommend avoiding it out of an abundance of caution.

Research-Backed Gut Health Supplement

The product we recommend for optimizing gut health and providing prebiotics is Supergut Fiber Mix. This powder product provides two different types of resistant starch from whole foods: green banana powder resistant starch and resistant potato starch.

Resistant starch is unique because it avoids digestion in the small intestine and instead provides nutritional support to healthy bacterial strains in the large intestine, functioning as a prebiotic.

A medical review published in the Advances in Nutrition journal analyzed data from various clinical trials and concluded that resistant starch intake was associated with improved gut health, weight loss in overweight and obese individuals, and improved insulin resistance.

Supergut’s fiber supplement contains no questionable additive ingredients. The only ingredients are different types of fiber sourced from whole foods.

Conclusion

We do not recommend Nu Biome for improving gut health. While the supplement may potentially be effective because it contains a probiotic ingredient, we cannot determine so conclusively because the brand publishes only the probiotic species and subspecies but not the specific probiotic strain.

We were unable to identify any effectively dosed ingredients in Nu Biome based on a review of clinical trials.

Consumption of resistant starch appears to be one of the most promising research-backed modalities for enhancing gut function, and may have secondary benefits such as improved insulin function and weight in overweight and obese individuals.
