BelliWelli is a supplement brand that sells powders marketed for gut health and weight management support. The brand claims their powder can "aid in weight management, and support a healthy microbiome."

But does BelliWelli powder contain research-backed ingredients for weight loss? What about for gut health? Does it contain any unhealthy ingredients? And how do real users rate and describe its effects?

In this article we'll answer all of these questions and more, as we analyze the ingredients in BelliWelli powder to give our take on whether or not the supplement is likely to be effective for weight loss and gut health support, and whether or not it's healthy.

We'll also feature real customer reviews, compare BelliWelli to other popular gut health supplements, and discuss the potential for side effects. 

Key takeaways:

• Unflavored version is much healthier than flavored versions
• Fiber dose is relatively low
• We do not currently recommend BelliWelli powder

Ingredient Analysis

The active ingredients in BelliWelli Wild Berry Powder are shown below:

Collagen peptides are clinically shown to have an anti-aging effect.

However, a meta-study published in the Journal of Drugs in Dermatology journal suggests that the minimum effective dose is 2.5 grams (g) daily, or 25% more than included in BelliWelli powder.

Bacillus coagulans MTCC 5856 is a probiotic strain that was shown in a 2023 clinical trial to reduce gas and bloating.

Organic acacia fiber is a type of soluble fiber that's clinically shown to support weight loss, as we documented in our Xyngular reviews article.

We're unable to identify any clinical backing on the vitamin or mineral ingredients for weight loss or gut health.

The inactive ingredients in BelliWelli Wild Berry powder are shown below:

Organic cane sugar is a type of refined sugar, and added sugar in excess is clinically shown to increase inflammation in the body.

Many Americans already consume too much added sugar in diet, so we generally recommend avoiding weight loss supplements containing it.

Citric acid is a flavoring ingredient that's clinically shown to cause inflammation in some individuals, as we discussed in our Nu Biome review article.

Natural flavors may include solvents and preservatives, according to a 2009 medical review.

BelliWelli Powder sells an Unflavored version that's free of all three of these inactive ingredients, and we consider this version to be significantly healthier than the flavored versions.

Overall, we consider BelliWelli powder likely to support weight loss and gut health.

We do not currently recommend this supplement due to the inclusion of vitamin and mineral additives.

As we've stated in many Illuminate Health reviews, we have not come across any clinical evidence that vitamin and mineral supplementation is beneficial in individuals without vitamin and mineral deficiencies.
