A bright everyday lifestyle moment
Nazan Arabul, founder of Gut Theory and psychologist

The founder

The psychologist behind the habit.

Nazan wanted more than another probiotic. But supporting her gut in different ways meant keeping up with several products.

She saw a simpler answer: five clear roles in one daily scoop.

Over two years, she worked with nutritionists and food scientists to choose ingredients with human research behind them.

As a psychologist, she knew consistency matters. If something is hard to take, it is unlikely to become a habit.

That meant a bright citrus berry taste, ready in under a minute and simple enough for every day.

“I wanted one simple habit that could stay with me through café breakfasts, work lunches and travel.”

Good questions

Know before you choose.

Short, straight answers about the formula, how to use it and what the evidence can—and cannot—tell you.

01What makes this different from a greens powder?

A greens powder usually focuses on broad nutrition. The Daily Buffer™ focuses on five gut-support jobs: the gut lining, probiotic strains, prebiotic fibre, plant compounds and digestive enzymes. It does not replace fruit or vegetables.

02What does it taste and look like?

It has a Citrus Berry flavour and mixes into a bright yellow drink. Add one level scoop (10 g) to 200–250 mL of cold water.

03Why do you use Reb M stevia?

Reb M is a specific, purified steviol glycoside used for sweetness. We chose a high-purity Reb M grade—not a generic stevia blend—because it gives a cleaner taste with less of the bitter, lingering finish often linked with stevia. It keeps Citrus Berry bright without using sugar as the main sweetener. Reb M is permitted for use in Australia and New Zealand. Its job here is taste—not gut support—so we do not count it as an active ingredient. FSANZ guidance ↗ Reb M sensory study ↗

04How and when should I take it?

Take one level scoop (10 g) once daily. Have it with a meal when you want digestive-enzyme support for that meal.

05How long until I notice something?

Some support is connected to the meal you take it with. Regularity and day-to-day support depend on consistent use. Timing differs from person to person, so no exact result or timeframe is promised.

06Why are the probiotic strains named?

Different probiotic strains can have different evidence. We name all three so you can see exactly what is in the formula and check the research linked to each strain.

07Does it contain fillers, maltodextrin or proprietary blends?

No. The Daily Buffer™ contains no fillers, no maltodextrin and no proprietary blends. Every active ingredient and amount is shown, so you can understand the formula, compare it properly and follow the research connected to each ingredient or named strain.

08Can I take it with medication?

Ask your doctor or pharmacist before use if you take medication, have a diagnosed condition, are pregnant or breastfeeding, or are planning treatment.
