We hear this a lot, and we completely understand the scepticism. So many of our customers had tried everything before finding TUMME, and the difference comes down to one thing: sterculia is a completely different type of fibre to anything most people have tried before.
It won't cause gas or bloating: Most common fibres break down inside your gut, which is what causes that uncomfortable gas and bloating. Sterculia doesn't do that. It passes through gently, adding bulk and softness to your stool without any of the side effects that put people off other fibres.
It works with your body, not against it: Rather than forcing things to speed up like a laxative, sterculia simply helps your body form a soft, comfortable stool that's easy to pass. Customers describe it as gentle and predictable, without the urgency or cramping they've experienced with other products.
People have loved it for decades: Sterculia has a devoted following going back many years under the Normafibe and Normacol brands. When those products were discontinued, hundreds of Australians spent years searching for a replacement. TUMME is what they found, and the reviews speak for themselves.
Yes, it really is. TUMME Natural Fibre contains sterculia, the same active ingredient that made Normafibe and Normacol so effective for so many people. It is currently the only sterculia-based supplement available in Australia.
The relief you remember: Customers who searched for months or even years after their previous product was discontinued describe TUMME as the closest match they've found. The same gentle, predictable relief for IBS, diverticulitis, and chronic constipation that they knew and trusted.
One thing to know: TUMME comes in capsules rather than the granule sachets you may have been used to. Most customers adapt quickly, though the capsules are on the larger side and you'll take a few each day.
Give yourself a little time: Even if you knew exactly how much Normafibe worked for you, we recommend starting low and building up over the first couple of weeks. Most former Normafibe and Normacol users find their sweet spot within a fortnight.
It sounds counterintuitive, but this comes down to how sterculia works. Rather than pushing things one way or another, it acts as a gentle bulking fibre that helps support comfortable, well-formed stools — whatever your starting point.
If you tend towards constipation: Sterculia adds gentle bulk and softness to hard or slow-moving stools, making them easier to pass. Many customers describe finally having that reliable, comfortable morning routine they'd been missing.
If you tend towards loose or urgent stools: The same gentle bulking action can help firm things up. If this sounds like you, a lower dose is usually the right starting point — you're not trying to speed anything up, just helping support a more comfortable rhythm.
No gas, no cramping: Because sterculia doesn't break down in your gut the way other fibres do, it won't cause the uncomfortable gas and bloating that puts so many people off fibre supplements. Most customers are genuinely surprised by how well they tolerate it.
Many of our customers have sensitive guts and had tried a lot of things before finding TUMME. What tends to set sterculia apart for them is how gently it works — no urgency, no cramping, and none of the side effects that put them off other fibres.
Gentle by design: Sterculia doesn't break down in your gut, which means it avoids the gas and bloating that other fibres can cause. For people who have found fibre supplements hard to tolerate in the past, this often makes a real difference.
Start low and go slow: If your gut is sensitive, starting with just 1 to 2 capsules a day and building up gradually gives you the best chance of a comfortable experience. Many customers who take their time finding the right dose go on to be among our most loyal.
Always check with your healthcare provider: If you have a diagnosed condition or take regular medication, please speak with your doctor or pharmacist before starting a new fibre supplement. They can help you decide whether it's right for you and how best to introduce it.
Welcome to the TUMME community! The most important thing is to start gently and give your body time to adjust. Starting too high too quickly is the most common reason people don't get the results they're hoping for.
Start with 2 capsules a day in week one: Take them with a big glass of water at the same time each day. Your gut needs a little time to get used to a new fibre, so starting low gives you the best chance of a smooth, comfortable experience from the beginning.
Adjust slowly from week two: If things feel good, stay where you are. If you feel like you need a little more, add 1 or 2 capsules and give your body 3 or 4 days before making another change. Our customers land on anywhere from 2 to 12 capsules a day, so finding your number takes a little time and that is completely normal.
Drink plenty of water: Sterculia works by absorbing water to form that gentle bulk, so staying well hydrated really does make a difference. Aim for 6 to 8 glasses of water a day, especially in those first few weeks.
Please don't worry, a few days is too early to tell. TUMME builds up gently over time as your gut gets used to it, and most customers notice the real difference somewhere between one and three weeks in.
The early signs are quiet ones: The first thing most people notice is a change in the texture or consistency of their stools before anything else shifts. This is a good sign. Don't mistake a gentle start for nothing happening at all.
Give it two full weeks at your current dose: The customers who share the most heartfelt reviews are almost always the ones who stayed consistent and adjusted slowly. If nothing has changed after 14 days, try increasing your dose a little before drawing any conclusions.
Consistency is everything: Taking it at the same time each day with plenty of water makes a real difference to how well it works. If you've had a few missed days or changes in routine, give it another week of steady use before you reassess.
First of all, don't panic. This is almost always a sign that you've started with a little too much too soon, and it is very easy to fix. Most customers who felt this way early on went on to find a dose that worked beautifully for them.
Drop back to 1 or 2 capsules a day: Give your gut a few days to settle, then increase by just one capsule every 3 or 4 days. Your gut is very adaptable, it just needs a little more time than you might expect, especially if you haven't taken a fibre supplement regularly before.
Check how much water you're drinking: Not drinking enough water is one of the most common causes of early discomfort with sterculia. Without enough fluid, it can sit in your gut and cause that uncomfortable bloated feeling. Try increasing your water intake before you reduce your dose.
Please don't give up after one uncomfortable day: The vast majority of early discomfort is simply about finding the right dose, and it is absolutely fixable. If things are still uncomfortable after 5 to 7 days at a very low dose with plenty of water, it may just not be right for your body, but please give yourself the chance to find out first.
This is a clear sign your dose is a little high for where your body is right now, and the good news is it is very easy to sort out. Simply reduce your dose and give your system a few days to settle.
Reduce straight away: Drop back to 1 or 2 capsules and stay there until things feel normal again, usually just 2 or 3 days. Then build back up slowly, adding one capsule every 4 or 5 days until you find the amount that feels just right.
Your ideal dose might be lower than you think: The amount on the label is just a starting point, not a rule. Lots of our customers, especially those with a more sensitive gut, do really well on just 2 to 4 capsules a day. More is not always better.
This is actually encouraging: If sterculia is having any effect at all, even if it feels like too much right now, it means it is working in your gut. You just need to find the amount that brings you to that comfortable, reliable place. Most customers who go through this early stage end up being some of our happiest.
