GLP-1 reshapes your gut.
Probiotic 40B rebuilds it.

GLP-1 medications slow gastric emptying and alter the gut environment — disrupting the microbiome that controls digestion, immunity, and even mood. Probiotic 40B restores the balance.

The GLP-1 gut effect

Slower digestion means
a changed microbiome.

GLP-1 medications are designed to slow gastric emptying — that's part of how they create satiety. But slower transit time changes which bacteria thrive in your gut, and not always for the better.

Bloating, constipation, and unpredictable digestion on GLP-1 are microbiome signals. The same gut environment controls nutrient absorption, immune response, and even serotonin production.

Probiotic 40B specifically targets the strains most disrupted by altered gut motility — repopulating what GLP-1 displaces.

Full formula

Every ingredient.
Every dose. Every reason.

Lactobacillus acidophilus

8B CFU

The most studied probiotic strain. Supports lactose digestion, reduces bloating, and competes against pathogenic bacteria.

Bifidobacterium lactis

8B CFU

Strongly linked to reduced constipation and improved bowel regularity — directly relevant to GLP-1-induced slow transit.

Lactobacillus plantarum

6B CFU

Reduces intestinal permeability and bloating. Produces short-chain fatty acids that feed the gut lining.

Lactobacillus rhamnosus

6B CFU

Supports immune modulation and reduces GI inflammation.

6-strain support blend

12B CFU

Bifidobacterium longum, B. breve, L. casei, L. bulgaricus, L. salivarius, Streptococcus thermophilus — covering the full spectrum of gut compartments.

Common questions

Everything you want to know.

Will this help with GLP-1 nausea?

It can. Gut dysbiosis exacerbates nausea — a balanced microbiome produces less gas and reduces the inflammatory signalling that makes nausea worse.

Do I need to refrigerate it?

No. The strains are freeze-dried and shelf-stable for 24 months at room temperature.

When should I take it?

In the morning with breakfast. Food buffers stomach acid and improves probiotic survival through the GI tract.

What if it doesn't work?
