Nu Biome is a pink-colored gut health supplement marketed by Nu Skin, a brand primarily known for its skincare products. The supplement is manufactured by Pharmanex. This article will analyze Nu Biome, examining its ingredients and the available research to determine its potential effectiveness in optimizing gut health. We will also address any controversies surrounding the brand and evaluate the logic behind its formulation.
Ingredient Analysis: What's Inside Nu Biome?
To the credit of Nu Skin, the company now publishes the dose of each active ingredient. However, a critical evaluation of these ingredients is necessary to determine the supplement's potential efficacy.
Chromium: Nu Biome contains a significant dose of chromium, a mineral. However, we're unable to identify any medical studies suggesting it improves gut health. It seems illogical in our opinion to take 286% of the Daily Value (DV) of a mineral on a regular basis without being deficient in that mineral.
Pomegranate Fruit Extract: Pomegranate fruit extract was shown in an in vitro (test tube) trial to increase probiotic concentrations in the gut, but this is a weaker standard of evidence than a human trial.
Bifidobacterium animalis subsp.: The inclusion of this probiotic strain is a positive aspect of the formulation, as probiotics can contribute to gut health.

Citric Acid: Citric acid is a preservative and flavor-enhancing ingredient that’s typically manufactured from a fungus called Aspergillus niger.
Natural Flavor: Natural flavor is a broad term that refers to any number of chemical compounds used as flavoring agents. The lack of specificity makes it difficult to assess the potential impact of this ingredient.
The Nu Skin Controversy and Marketing Tactics
Nu Skin employs a direct sales model, and its marketing often relies on anecdotal evidence and enthusiastic testimonials. One example of this is the promotion of NuBiome alongside another product called Meta, with claims such as: "Meta is now finally AVAILABLE + NuBiome TOGETHER: 💜Protect GI Tract & organs 💖Help promote better gut health 💜Help remove fat from liver 💖Help improve antioxidant defense system 💜Help maintain healthy blood glucose." Such claims should be viewed with skepticism, especially when presented without robust scientific backing.
The marketing materials also include statements like, "Did you know? Only 1 in 8 people are Metabolically healthy??? I had no idea 🧐 Meta is the #1#1roduct on the market right now." This type of messaging can create a sense of urgency and encourage consumers to purchase the product without fully understanding its benefits or limitations.
Evaluating the Evidence: Does Nu Biome Live Up to the Hype?
Based on the available information, there is limited evidence to support the claim that Nu Biome significantly improves gut health or promotes weight loss.

The inclusion of Bifidobacterium animalis subsp. is a positive aspect, but the overall effectiveness of the supplement depends on the specific strain, dosage, and individual response.
The in vitro study on pomegranate fruit extract is not sufficient to demonstrate a clinically relevant effect in humans.
The high dose of chromium raises concerns about potential risks, especially in individuals who are not deficient in this mineral.
