How much fibre do you actually need? (Australia)
It's one of those numbers everyone senses they're missing and almost nobody knows. "Eat more fibre" is good advice, but more than what, exactly? So let's put a real Australian figure to it — where it comes from, why most of us fall short, and where a fibre powder honestly fits (hint: after your plate, not instead of it).
The number, from the people who set it
In Australia and New Zealand, fibre intakes are guided by the NHMRC Nutrient Reference Values. For dietary fibre they set an Adequate Intake (AI) — the amount typically eaten by healthy people — of 30 g a day for adult men and 25 g a day for adult women.
They go a step further with a Suggested Dietary Target (SDT): a higher intake linked with reduced risk of chronic disease. That target is 38 g a day for men and 28 g a day for women (NHMRC, 2006).
So the honest answer to "how much fibre do I actually need?" is roughly 25–30 g a day to be adequate, and closer to 28–38 g if you're aiming at the target most associated with long-term health. Children need less, scaled to age; pregnancy and breastfeeding nudge the numbers up a little. Your clinician or an Accredited Practising Dietitian can pin down your own figure.
This is general information, not medical advice. If you have a gut condition, are pregnant, or take medication, talk to your clinician before changing your fibre intake or adding a supplement.
The gap: most of us don't get there
Here's the uncomfortable part. On average, Australian adults eat around 20–25 g of fibre a day — men a little over women, but both short of the mark. When researchers analysed the national nutrition survey data, more than 7 in 10 adults fell below the Adequate Intake, and the vast majority didn't reach the higher Suggested Dietary Target (Fayet-Moore et al., 2018; ABS Australian Health Survey).
That's not a moral failing — it's how modern eating shakes out. Refined grains, not-quite-enough veg, fruit skipped in favour of juice, and busy days all shave a few grams off here and there. The gap between "what we eat" and "what's recommended" is usually only 5 to 10 g a day. Small on paper. Worth closing.
Where fibre actually comes from (food first, always)
Before anything with a scoop enters the conversation, it's worth seeing how ordinary food stacks up, because whole foods do the heavy lifting:
- Wholegrains — a bowl of rolled oats is roughly 4 g; two slices of dense wholegrain bread, around 4–5 g.
- Legumes — a cup of cooked lentils or chickpeas can carry 8–10 g. Pound for pound, the best value going.
- Vegetables — a cup of cooked broccoli or a couple of carrots, a few grams each; they add up fast across a day.
- Fruit — an apple with skin, a pear, a handful of berries, 3–5 g apiece.
- Nuts and seeds — a tablespoon of chia is about 5 g; a small handful of almonds, a few more.
Whole foods bring more than a fibre count. They carry a mix of fibre types, plus water, vitamins, minerals and the plant compounds that fibre travels with — and the research on fibre and gut health consistently points back to dietary patterns rich in varied, whole-food fibre, not to any single isolated ingredient (Gill et al., 2021; Slavin, 2013). If you can hit your number with food, that's the win. Genuinely.
So where does a fibre powder fit?
After the food. A blend like ours is a top-up for the gap, not a substitute for the plate.
Picture a day where you managed maybe 20 g from meals — decent, but a few grams short of adequate and well short of the 28–38 g target. That's the shortfall a supplement is built for: a convenient way to add fibre on the days your food didn't quite get you there, especially the varied kinds of fibre a single food rarely delivers on its own.
That's the thinking behind . One 12 g serve delivers 11 g of soluble fibre, drawn from six named sources — soluble corn fibre, gum arabic (acacia), PHGG (partially hydrolysed guar gum), polydextrose, sodium alginate (from kelp) and citrus pectin — and we name every one rather than hiding behind a "proprietary blend" (the full breakdown is on the ).
It's unflavoured, dissolves into water, coffee, smoothies — whatever you're already drinking — with no added sugar, sweeteners or flavours.
Why six, with the grams shown? Because a lot of the category hides behind a single fibre or an undisclosed "proprietary blend", and you can't top up what you can't see. Just as we publish our iodine numbers on the sea moss side, here we show every gram. You can read our testing and documentation on the .
A note on wording: we describe the gram amounts factually and leave formal nutrient-content phrasing (the regulated "source of fibre"-style claims) to the label as approved. The point of this piece is the arithmetic, not a health claim.
When 6-in-1 is not the right pick
Honesty means naming who shouldn't bother:
- You're already at your number from food. If your meals reliably land you at 25–30 g, you may not need a supplement at all. Keep doing what you're doing.
- You just want cheap bulk psyllium. If a single, low-cost soluble fibre does the job for you, buy that. A six-source blend is a different tool, and it's fine if it's not your tool.
- Your clinician has you on a specific single fibre. If you've been directed to a particular fibre for a particular reason, follow that advice, not a blend.
- You want the whole-food route. Lentils, oats, veg and fruit are a complete and excellent answer. A powder can't replace what a varied plate gives you.
A word on gut sensitivity and "low FODMAP"
If your gut is sensitive, more fibre isn't automatically better — the type and pace matter, and adding fibre too fast can leave you bloated. Low FODMAP is a useful dietary concept here, and it's best applied with a dietitian rather than guessed at. We describe our fibres factually and don't present any certification we haven't confirmed. If you're managing a diagnosed gut condition, that's a conversation for your clinician, not a blog.
The short version
- Aim for 25–30 g of fibre a day (adequate), and toward 28–38 g if you're chasing the target linked to long-term health.
- Most Australians land around 20–25 g — a gap of roughly 5–10 g.
- Food first: wholegrains, legumes, veg, fruit, nuts and seeds do the real work, and bring more than fibre alone.
- A blend like is a top-up after food — six named fibres, 11 g soluble per 12 g serve, every gram on show.
Good for your belly starts on your plate. A fibre powder just helps you close the last few grams — and, in our case, tells you exactly what's in each scoop.
