SkinnyFit NLP-1
A berberine and probiotic blend at $68.96, sold on wellness consistency and healthy weight maintenance rather than on explicit weight loss promises. The product name is the thing to notice: NLP-1 differs by a single letter from GLP-1, and the product URL uses 'glp-1-natural'. The formula itself is a reasonable pairing; the naming does work the ingredients cannot.

What’s in it
Amounts are shown only where the manufacturer publishes them. Anything without a figure is undisclosed — and for an active ingredient, an undisclosed dose is the central problem with this category.

How the manufacturer says it works
SkinnyFit describes it as a natural blend of berberine and probiotics designed to support your wellness journey, helping you feel your best and stay consistent with a balanced, healthy lifestyle, particularly as staying on track becomes harder with age.
What the evidence actually supports
Pairing berberine with probiotics is defensible on its own terms. Berberine has the strongest ingredient-level research in this category for glucose and lipid markers, and there is an interesting mechanistic link between the two, since berberine's poor absorption means much of it interacts with gut bacteria — indeed gut bacteria are what convert berberine into dihydroberberine. The claims made are also restrained: consistency and healthy weight maintenance rather than promises about pounds lost.
Where that evidence stops
The name is the central issue. NLP-1 sits one letter from GLP-1, the URL reads 'glp-1-natural', and neither berberine nor a probiotic acts on the GLP-1 receptor — berberine works through AMPK. Nothing about this formula is comparable to a GLP-1 medication. Neither ingredient carries a published amount: berberine's dose and form are unstated, and probiotic strains and counts are absent, so nothing can be assessed. Berberine also inhibits CYP3A4 and interacts with many prescription medicines, and no warning appears. At $68.96 this is among the more expensive products here for a formula with no published specifications.
Strengths and problems

- Neither berberine dose nor probiotic strains and counts published
- No CYP3A4 interaction warning despite berberine content
- $68.96 for a formula with no published specifications

May suit
Hard to justify over a labelled berberine and a labelled probiotic bought separately for less.
Do not use if

Frequently asked
Is NLP-1 related to GLP-1?
No. GLP-1 is glucagon-like peptide-1, a hormone with a specific receptor that prescription medications target. NLP-1 is a product name. The ingredients — berberine and probiotics — do not act on that receptor: berberine works through AMPK, an entirely different pathway. A name one letter removed from a drug class, on a URL containing 'glp-1-natural', invites an association the formula does not support.
