Research peptides for nutritionists & dietitians in South Africa

Registered dietitians and nutritionists in South Africa have become the de facto interpreters of peptide news. A client in Centurion reads about a gut-healing peptide; a client in Somerset West asks about satiety peptides after a documentary. The practitioner needs to know the primary literature well enough to answer without endorsing.

This page is the primary-literature summary. It covers gut-mucosa and barrier research, the incretin and amylin satiety literature where it genuinely involves peptides, and the mitochondrial metabolism work. It names the compounds that appear in each and grades the evidence. It is not nutrition advice, and the compounds are supplied for laboratory research only.

What this field's literature looks at

Gut research is where peptides and nutrition science overlap most. BPC-157 was isolated from gastric juice and is studied in gut-lining, ulcer and mucosal-barrier models; KPV is studied in colitis models, including targeted oral delivery to inflamed colon; VIP is studied for intestinal secretory-cell differentiation and radiation-injury protection; NAD+ metabolism is studied in intestinal stem-cell and barrier models. These are animal and tissue studies with mechanistic endpoints.

Satiety and metabolism form the second literature. Incretin and amylin analogues such as tirzepatide, retatrutide and eloralintide have large human trials measuring weight and cardiometabolic markers, and dietitians increasingly read those trials directly; they are listed on the site with their own research pages. Mitochondrial peptides such as MOTS-c are studied in mouse metabolism for AMPK activation, glucose handling and diet-induced insulin resistance.

  • Exercise-responsive metabolic peptides

Compounds that recur in this literature

Research context only — what each compound has been studied for in published work, not what it does for anyone. Independently tested by Janoshik Analytical.

BPC-157

Research vial

Isolated from gastric juice and studied as a native cytoprotective peptide: gut lining, ulcer and mucosal-barrier restoration in animal models. The gut-brain axis work on dopaminergic and serotonergic signalling is the second thread dietitians meet.

KPV

Research vial

The α-MSH tripeptide studied in colitis models for dramatic attenuation of bowel inflammation, including engineered oral delivery systems that release it in inflamed colon tissue. Mechanism-level research, not a dietary tool.

View product and certificate →

VIP

Research vial

Vasoactive intestinal peptide, a gut hormone by discovery. Recent models report secretory-cell differentiation and reduced radiation-induced intestinal injury, and its receptors are reviewed across immune and neural tissue.

MOTS-c

Research vial

The mitochondrial peptide studied in mouse metabolism for AMPK activation, fatty-acid oxidation and reversal of diet-induced insulin resistance. Its plasma level responds to exercise and declines with age.

NAD+

Research vial

The coenzyme behind sirtuin activity, studied in intestinal barrier models and in precursor trials on insulin sensitivity with mixed human results. A nutrition reader meets it through the niacin and precursor literature.

Questions nutritionists & dietitians ask

Is BPC-157 a gut-healing supplement?

No. It is a research peptide studied in animal models of gut lining and ulcer healing. It is not a supplement, has minimal human data, and is supplied for laboratory research only.

Where do the incretin trials fit?

They are large human trials in the metabolic literature. Those compounds have their own research pages on the site; this page covers the gut and mitochondrial work.

Can a dietetics practice order for research?

Yes. Compounds are supplied for laboratory research with certificates and are not for clients. We do not provide protocols.

How is purity checked?

By an independent Janoshik Analytical certificate per compound, stating identity and HPLC purity. Unpublished certificates are available on request.

Are these compounds food-grade or oral?

No. They are lyophilised research reagents. Nothing on the site is a food, supplement or oral product.
