Gut Health Supplements Built on Clinical Doses, Not Marketing Doses

Targeted gut-brain axis support designed around the root drivers of occasional bloating, sluggish digestion, and stress-driven gut discomfort, not just the symptoms. Every dose is printed on the label so you can compare it to what the research studied.

Every Shuven™ formula is dose-transparent and clinically informed. No proprietary blends. No hidden amounts.

Most Gut Supplements Hide Their Doses. We Print Ours.

The gut and brain are in constant two-way communication through neural, hormonal, and immune signaling, a relationship mapped across a foundational review of the gut-brain axis. When that signaling is disrupted, the result shows up as bloating, irregular digestion, low energy, and a foggy, wired-but-tired feeling.

The problem with most of the category is not the ingredient list. It is the dose. Brands stack a recognizable name onto a label at a fraction of the amount studied, then bury it inside a proprietary blend so you cannot tell how much you are actually getting. Shuven was built on the opposite principle: clinical doses wherever a capsule can deliver them, every ingredient and amount disclosed, and a plain statement wherever an amount sits below the studied dose. If you want the science behind the system, our guide to gut-brain axis supplements breaks down the mechanism and the evidence in depth.

The Shuven Standard

Clinical doses, no proprietary blends. Every ingredient and its exact amount is printed on the label, so you can compare each dose to the research it is based on.
Dose transparency as the default. Where an ingredient sits below a full studied dose, we say so and explain the mechanism or traditional-use rationale rather than implying an outcome the dose cannot support.
Branded, standardized ingredients. KSM-66, Suntheanine, Albion TRAACS, AstaPure, BioPerine, and Sunfiber, specified by standardization percentage, not generic powder.
Third-party testing on every batch. Every production batch will be independently tested for identity, potency, and contaminants before it ships.
Clean capsules. Three vegan caps per serving, size 0 HPMC, no proprietary fillers.
cGMP manufacturing. Every formula will be produced under FDA dietary supplement cGMP rules (21 CFR Part 111).

Built for the Real Reasons Digestion Breaks Down

Gut symptoms rarely travel alone. Stress slows digestion, poor sleep raises cortisol, and an irritated gut lining feeds the whole loop. Shuven maps each formula to a specific link in that chain.

If bloating and irregularity are your day-to-day, start by understanding how to fix bloating naturally and what is actually driving the discomfort. If stress sits underneath the gut symptoms, our breakdown of supplements for stress and anxiety covers the cortisol-digestion connection and how to interrupt it. When the issue is an irritated gut lining, the research-backed approach to supporting the gut barrier explains which compounds matter and at what dose. And if the symptom you notice most is mental, that wired, foggy, unfocused feeling, the guide to clearing brain fog and mental clarity connects it back to the gut.

Each guide links to the formula built for that job, so you are never guessing which product fits.

Founder-Led, Science-First

Shuven (pronounced SHOO-ven) is the new name for CalmGut, an independent, U.S.-based brand founded in 2025 on one rule: every dose fully disclosed, every time. The name is inspired by the Hebrew root shuv, to return, because the goal of every formula is the same: bring your gut, your calm, and your energy back to baseline. Same company, same formulas, same standards. Formulas are developed and reviewed by founder Ryan Pepple against the published evidence for each ingredient, and revised when the science says they should be. Questions about a formula or an ingredient go straight to hello@shuven.co.

Frequently Asked Questions

Is Shuven the same company as CalmGut?

Yes. Shuven is the new name for CalmGut. The company (CalmGut LLC), the formulas, the doses, and the testing standards are unchanged. Only the name and packaging are new. Existing accounts carry over automatically.

When will Shuven ship?

Shuven is in pre-launch and not shipping yet. Join the launch list below and we will email you the day formulas are available.

What makes Shuven different from other gut health supplements?

Dose transparency. Every ingredient and its exact milligram amount is printed on the label so you can compare it to what the research studied. There are no proprietary blends hiding low amounts, and where an ingredient sits below a full studied dose, we disclose it and explain the rationale instead of implying an outcome it cannot deliver.

Do Shuven formulas use proprietary blends?

No. Proprietary blends let brands list an impressive ingredient at an unstated, often tiny amount. Shuven prints every ingredient and dose individually so you can see exactly what you are taking and compare it to the research yourself.

Will Shuven supplements be third-party tested?

Yes. Every production batch will be independently tested for identity, potency, and contaminants before it ships, and every formula uses branded, standardized ingredients.

Are Shuven formulas vegan?

Every formula uses size 0 HPMC vegan capsules. Reset, Focus, Sleep, Morning, and Glow are fully vegan; Glow is built on a collagen-cofactor and barrier-support system with no collagen of any kind. Bloat contains a digestive enzyme blend, and we will confirm its vegan status once enzyme sourcing is verified by our manufacturer.

Which Shuven product should I start with?

Most people start with Reset, the daily gut-foundation formula, or the Starter Gut Health Bundle if they want a complete routine in one step. If a specific symptom dominates (bloating, stress, sleep, energy, or skin), start with the formula built for that job.
