MacroBlue is designed to taste delicious and mix easily into water, yoghurt or other liquids as you choose. Without the glugginess or heavy feel. Different flavours to suit your day, with bright fruit and citrus, or vanilla and flavourless options for people who prefer something more neutral to go with yoghurt or a smoothie. Most of all, we've carefully designed our formula to include psyllium, without the gluggy mouth feel that many people find challenging to take for the long-term. Nutritionist-formulated, where health, taste and consistency come first. Helping you keep up your habits, for life.
Texture matters too. Fibre powders can vary enormously in how they mix and feel, so MacroBlue is designed to be easy to drink as part of a normal daily routine rather than heavy, gritty or overly thick.
Yes. MacroBlue contains both probiotics and prebiotic fibre, depending on the formula. Probiotics add beneficial microorganisms, while prebiotic fibre helps feed beneficial microorganisms already living in the gut.
Different fibres have different physical and fermentative properties, and different gut microbes can use them in different ways.
MacroBlue combines multiple fibre sources so one serve can provide a broader range of fibre characteristics rather than relying on a single source alone.
MacroBlue is designed as a fibre supplement plus the things that support your day. Each scoop combines diverse fibre sources with active ingredients such as creatine, magnesium, vitamins B, C and D, zinc, calcium and other nutrients. Please check the individual product ingredients, as formulas may differ.
The idea is simple: daily fibre nutrition in one scoop that actually tastes delicious. One useful habit. One delicious serve. More for your day.
MacroBlue provides 10g of fibre per serve, from up to seven complementary fibre sources depending on the formula.
That makes it an excellent source of dietary fibre under Australian food standards, and a simple way to make a meaningful contribution toward your daily fibre intake in one scoop.

Fibre supplements can be useful where your diet fall short of the recommended intake. Research indicates that 95% of Americans and 80% of Australians are reported to fall short of their Suggested Dietary Target (SDT).
Supplements can be made from single or multiple fibres. Different fibres can do different jobs.
Some feed particular gut microbes or are fermented by them, producing short-chain fatty acids such as butyrate that play important roles in the gut environment. Certain viscous fibres can slow nutrient absorption and have been shown to improve blood glucose and cholesterol measures in specific populations. Others help support regularity by holding water and adding bulk.
A multi-fibre supplement provides fibre from more than one source. MacroBlue's full fibre formula combines up to seven fibre sources with different solubility, viscosity, water-holding and fermentative properties, providing 10g of dietary fibre per serve.
Prebiotic fibre reaches the large intestine largely undigested, where certain beneficial gut microbes can use it as food. Different prebiotic fibres can favour different microbes and produce different fermentation patterns, which is one reason fibre diversity matters. In your diet, prebiotic fibre can come from vegetables and fruits like Jerusalem artichokes, garlic, leeks, asparagus, chicory root, or green bananas.

Probiotics are live microorganisms. Prebiotics are the fibres and other compounds that feed beneficial microorganisms already living in your gut. Think of probiotics as adding plants to a garden, and prebiotics as feeding the garden you already have.

Australian Adequate Intakes (AI) are 30g per day for adult men and 25g for adult women. Suggested Dietary Targets (SDT) are higher at 38g and 28g respectively.
Most people should aim to get fibre from a wide range of foods such as vegetables, fruit, legumes, wholegrains, nuts and seeds. A supplement can help fill the gap when diet alone is not getting you there. Research indicates over 70% of Australians don't achieve their AI and over 80% of Australians don't reach the SDT.
Soluble fibre dissolves or disperses in water and is found in foods such as oats, barley, legumes, apples, citrus and some seeds. Depending on the fibre, it can form a gel, slow digestion and be fermented by gut microbes.
Insoluble fibre is found in foods such as wheat bran, wholegrains, nuts, seeds and the skins of many fruits and vegetables. It generally adds bulk and helps material move through the digestive tract.
The distinction is useful, but not complete. Fibres also differ in viscosity, fermentability and water-holding capacity, which helps explain why different fibres have different effects in the gut.
For most healthy adults, fibre is something we should consume every day. If you are increasing your intake substantially, building up gradually can help your gut adapt.
If you have a gastrointestinal condition, have been advised to restrict fibre, or take medications that may be affected by fibre intake, check with your doctor or dietitian before making it a daily supplement.
It depends on the fibre, the amount you take and what you are hoping to change. Some effects on bowel regularity can happen relatively quickly, while changes involving fermentation and the gut microbiome may take longer and vary from person to person.
Fibre works best as a consistent daily habit rather than something you take only when you notice a problem.
Any time that works for you. Morning, afternoon or with a meal can all work. Pre workout, post run, or hydrating post swim mixed with water.
What matters more is taking it regularly and drinking enough fluid. If your fibre intake is increasing significantly, it can also help to build up gradually rather than jumping straight to a full serve.
A fibre supplement can be useful if your usual diet regularly falls short of your fibre needs. It can be a simple way to help close the gap, especially on busy days when meals are less varied than you would like.
MacroBlue created one that provides an excellent source of dietary fibre, tastes great, fits easily into your routine, contributes to your broader nutrition goals and that you'll look forward to each day to help stick to your goals.
If you have a gastrointestinal condition, have been advised to limit fibre, take medications that may be affected by fibre intake, or have concerns about your digestion, speak with your doctor or dietitian before starting a fibre supplement.

MacroBlue is daily fibre and nutrition, that tastes delicious and helps you keep up your target habits, every day. Designed for people who want to live and move. Our core formula combines 10g of dietary fibre with prebiotic fibres, a probiotic, creatine, vitamins and minerals in one daily powder.
Different fibres have different physical and fermentative properties. Some dissolve in water, some form viscous gels, some resist digestion until the large intestine and some are readily fermented by gut microorganisms. That is why we use a mix rather than treating every gram of fibre as interchangeable.
Australian Adequate Intake targets are 25g per day for adult women and 30g per day for adult men. The Suggested Dietary Target (SDT) for daily fibre intake in Australia is even higher, at 38 grams for men and 28 grams for women.
Most Australians fall far short of this target. We believe good health starts with a good, varied diet full of vegetables, proteins and great food. But we also know, sometimes we still fall short.
MacroBlue's full serve provides 10g of fibre, so it can make a substantial contribution alongside fibre from food.
We designed MacroBlue to be easy to add to your day. Fibre tolerance varies, particularly if your current intake is low. Start with half a scoop for 3 to 7 days, drink plenty of water and increase gradually to a full serve.
Yes. The formula includes prebiotic fibres such as Sunfiber® PHGG, Solnul® resistant potato starch, PreticX® XOS and BeniCaros® carrot fibre. Prebiotics and probiotics are different. A prebiotic is a substrate selectively used by microorganisms that confers a health benefit. A probiotic is a live microorganism that confers a health benefit when taken in adequate amounts.
Yes. Bacillus coagulans is used in many of our products. It is a highly shelf-stable probiotic. This is important, to avoid glugginess or issues with humidity. A common Australian concern. Check the product label for the exact strain and amount in each formula.
Our core formula includes vitamins A, C and D, magnesium, zinc and calcium, alongside fibre, prebiotics, probiotic and creatine. Exact amounts are shown on the product label and Nutrition Information Panel.
Yes, in some of our products. Creatine is included alongside the fibre, vitamin and mineral blend. Check each product label for the amount per serve.
Single-fibre supplements concentrate on one fibre with one particular set of properties. Psyllium is a soluble, highly viscous fibre that forms a gel in water and adds bulk to stool. PHGG (partially hydrolysed guar gum) is a soluble prebiotic fibre that is used by microorganisms in the large intestine. Other single-fibre products may contain only inulin, resistant starch, acacia fibre or wheat dextrin.
We take a broader approach. By providing up to 10g of dietary fibre from up to seven complementary sources, selected to provide an excellent source of fibre, from a combination of soluble, insoluble, prebiotic and resistant fibres, one scoop source contributes different physical and fermentative properties to support greater diversity in your diet.
We specifically formulated MacroBlue to avoid the thick, rapidly gel-forming texture associated with some fibre powders. It still contains psyllium, but the overall blend is designed to mix easily and be something you can enjoy every day.
That was one of our main requirements. MacroBlue comes in six flavoured options plus an unflavoured blend, so you can choose between a drink you enjoy on its own or something neutral to add to yoghurt, coffee, smoothies or food.
We designed MacroBlue to be easy to add to your day. Fibre tolerance varies, particularly if your current intake is low. Start with half a scoop for 3 to 7 days, drink plenty of water and increase gradually to a full serve.
All are fine! Choose the time you are most likely to remember. MacroBlue is designed to fit an existing routine, such as breakfast, a morning drink, an afternoon smoothie or around training.
MacroBlue is designed for everyday use, including around an active day. Choose the timing and drink format that feels best for you and follow the serving directions on the product.
As reported by Dietitians Australia (2026), dietary fibres are carbohydrates that our bodies cannot digest. Once they reach the large intestine, fibres may be broken down by the gut microbiome, providing fuel for the microbes' growth and activity.
Some fibres can provide bulk to our stool and help keep us regular. You can find fibres in wholegrain cereals, fruit, vegetables, legumes, nuts and seeds. You can also take fibre supplements.
There are many types of fibre, each with unique properties that influence how they behave in the gut.
Eating a range of fibres from different sources may support growth in diverse gut microbiome. This is thought to be most beneficial for health.
This is external research that solely relates to high-fibre and fermented foods and is not in any way intended to indicate specific outcomes of this product and, in particular, this product makes absolutely no claims in relation to cancer or any other conditions nor treatments.
However, the product, when taken as recommended, can provide an excellent source of fibre.
Fibre tolerance can vary considerably in people with IBS and other gastrointestinal conditions. If you have a diagnosed condition, persistent bloating, abdominal pain or significant changes in bowel habits, ask your doctor or dietitian whether increasing fibre is appropriate for you.

They can, especially if you increase fermentable fibre quickly. Gut microbes need time to adjust, and different fibres ferment at different rates, so some may feel gentler than others.
Starting gradually, drinking enough fluid and giving your gut time to adapt can help. If bloating is severe, persistent or painful, speak with your doctor or dietitian.
