What's coming

The three gaps most multivitamins ignore.

Living gluten-free changes more than what's on your plate. It can affect how well your body absorbs nutrients, and the same deficiencies keep showing up, even on a strict gluten-free diet.

Most multivitamins approach nutrition as one general problem. Gutline is built around three specific gaps: the nutrients that run low, the gut that has to absorb them, and the fibre that goes missing.

01
The first gap · The nutrients that run low

The nutrients documented to run low across gluten-free populations.

Not a generic multivitamin stack. The specific nutrients that published research keeps flagging in people living without gluten, in the forms the body absorbs most readily.

Iron
B12
Cobalamin
B9

From the research

A 2019 Mayo Clinic study of 309 patients found iron, B12 and zinc deficiencies were common even in newly diagnosed coeliacs without obvious symptoms.

A 2025 systematic review found vitamin D and B12 gaps persist across long-term gluten-free populations, even on a strict diet.

02
The second gap · The gut that has to absorb them

Nutrition for the cells that line the gut itself.

The gut lining is where absorption either works or doesn't. So rather than only replacing what the body failed to take in, this part supports the cells doing the absorbing.

03
The third gap · The fibre that goes missing

The fibre a gluten-free diet is structurally lower in.

Wholegrain wheat, rye and barley are dominant fibre sources in an ordinary diet. Gluten-free substitutes are usually built on refined starch, so the fibre goes missing and doesn't come back. We use a prebiotic fibre chosen specifically for sensitive digestive systems.

An honest note

No supplement treats coeliac disease. The only treatment is a strict gluten-free diet. Gutline is designed to sit alongside it, addressing the nutritional gaps that gluten-free living can leave behind.

Why one daily serve

Several things worth taking. One thing to remember.

You could buy each of these separately, at quality doses and forms. Here's what that actually costs, and why a generic multivitamin doesn't get you there either.

Bought separately
~$108
per month

Eight to ten separate products. Different bottles, different sizes, most half-used. Constant reordering.

Generic multivitamin
~$15
per month

Cheap, but built for a generic healthy adult. Wrong forms, token doses, misses most of what gluten-free living needs.

Gutline
$79
per month

One daily serve, designed for the gluten-free community, made in Australia under full regulatory oversight.

Standalone costs are indicative, based on quality Australian retail products at comparable doses and forms (mid-2026). The generic multivitamin comparison reflects typical supermarket formulations. Final Gutline pricing will be confirmed at launch. We'd rather show our working than make a claim we can't stand behind.

Questions

The things people ask us.

A once-daily product for people living gluten-free. We're deliberately not publishing the detail yet, because the formulation is still being finalised with our manufacturer and regulatory consultant. We'd rather say nothing than say something that changes.

Soon. It's in final development with our Australian manufacturer, and we haven't set a launch date yet. We're not going to invent one. When we have a real date, the founding list gets it before anyone else.

Nothing. No payment, no obligation. You'll get a small number of updates before launch and first access when it's ready. You can leave at any time.

Ben, who lives gluten-free and got tired of buying four separate things that were never designed for him. Gutline is an Australian company, built here, from scratch.

We're going through the proper Australian regulatory process rather than around it. That takes longer and costs more, and we think it's the right way to do this. We'll share the detail once it's complete.

From the founder

"Gutline started because nothing on the shelf was made for us. Not a general supplement with gluten free added as an afterthought, but something designed from the first ingredient around what a gluten-free diet actually leaves out."

The work has changed the product more than once, and it may change it again before launch. That's the nature of doing it properly. When there's genuine news, you'll hear it from me directly.
