Short answer: “post-GLP-1 companion” formulations are products designed for consumers who are on, or coming off, GLP-1 routines — where the common formulation goals are muscle and protein support, metabolic wellness, digestive comfort and nutrient density, in easy-to-take formats. This guide explains how to evaluate ingredients for that use case (claim-safe positioning, format fit and documentation) and links the ingredient routes Nutrition BioTech supplies.
How to evaluate an ingredient for post-GLP-1 companion formats
Assess four things before you sample: (1) claim boundary — keep language structure/function, no drug or weight-loss claims; (2) format fit — will it work in the gummy, stick pack, shake or capsule your buyer wants; (3) absorption and solubility — does the form disperse and behave well in that format; (4) documentation — COA, spec, stability and certifications on hand.
Ingredient routes for this category
- Metabolic wellness: Berberine Pro-Micelle and Dihydroberberine (Berbaflux) vs Berberine — improved-solubility routes for capsules, sticks, gummies. See also Pro-Micelle vs HCl.
- Gut / microbiome: Akkermansia (AKK) — see live vs pasteurized.
- Muscle and protein support: instantized creatine and related actives for shakes and sticks (samples on request).
- Cellular energy: our NAD ingredient platform for energy-focused companion concepts.

Identity and standardisation: what to specify on a COA for this category
The fastest way to compare suppliers in this category is at the identifier level: exact chemical form, CAS number, assay method and assay basis. These are the fields worth writing into a specification before comparing quotes.
| Ingredient form | Identity | What the numbers mean | What to specify |
|---|---|---|---|
| Berberine hydrochloride | CAS 633-65-8 · C20H18ClNO4 · 371.81 g/mol | ≈90.5% berberine by weight; 1 g berberine HCl ≈ 0.90 g berberine (336.36 ÷ 371.81) | HPLC assay; basis stated (as-is vs dried; salt vs moiety) |
| Berberine (moiety) | CAS 2086-83-1 · 336.36 g/mol | the reference moiety for label and cost math across all berberine forms | use as the common denominator when comparing forms |
| Dihydroberberine | CAS 483-15-8 · C20H21NO4 · 339.39 g/mol | the reduced (dihydro) form of berberine | HPLC assay with basis; impurity profile including residual berberine |
| Pasteurised Akkermansia muciniphila | strain + cell-count identity, not CAS-based | authorisation is strain-specific: Regulation (EU) 2022/168 covers pasteurised MucT (ATCC BAA-835) | strain designation per our specification; total cells/g and the counting method (e.g. flow cytometry); documentation available under buyer review |
A berberine quote is only comparable when the assay basis is stated: “98% berberine HCl” and “98% berberine (as moiety)” differ by roughly 10% in delivered berberine. State salt or moiety, and as-is or dried basis, on the specification before comparing prices.
For a biological ingredient such as Akkermansia muciniphila, identity sits at the strain and cell-count level rather than a CAS number, and regulatory status follows the strain, not the species. How these fields appear on a real certificate is covered in our guide to verifying a supplier COA.
Frequently asked questions
What does post-GLP-1 companion mean for a formulator?
It describes finished products aimed at consumers on or after GLP-1 routines, where the formulation goals are typically muscle/protein support, metabolic wellness, digestive comfort and nutrient density — positioned with structure/function language only.
Which ingredient forms work best in these formats?
Improved-solubility and format-friendly forms (e.g. Berberine Pro-Micelle, dihydroberberine, pasteurized AKK, instantized creatine) tend to be easier to work into gummies, sticks and shakes. We share solubility, stability and taste notes per format.
What documentation do you provide?
COA, specification, allergen and GMO statements, stability data and certifications on request.
Can I request samples across these routes?
Yes — tell us your target format and we will share specs and samples via our contact page.

How much berberine does berberine HCl deliver?
Berberine hydrochloride (CAS 633-65-8, 371.81 g/mol) is about 90.5% berberine by weight, because the berberine moiety accounts for 336.36 g/mol of the salt. One gram of berberine HCl therefore delivers roughly 0.90 g of berberine. Check whether a COA assay is expressed on the salt or on the berberine moiety before comparing suppliers.
How is pasteurised Akkermansia muciniphila quantified on a COA?
As a total cell count per gram, commonly measured by flow cytometry — not as a percentage assay. Identity is strain-specific: EU novel-food authorisation under Regulation (EU) 2022/168 covers pasteurised A. muciniphila MucT (ATCC BAA-835). A specification should state the strain designation alongside the cell count; our documentation is available under buyer review.
What should a dihydroberberine specification include?
Chemical identity (dihydroberberine, CAS 483-15-8, C20H21NO4, 339.39 g/mol), an HPLC assay with its basis stated, and an impurity profile including residual berberine. We provide the COA, specification and stability documentation for review before sampling.
