If this sounds familiar
You go every two or three days. When you do, it's a strain.
By the afternoon you're bloated, and your waistband feels tighter than it did this morning.
So you did the sensible thing: you added more fibre. And somehow it made everything worse. More gas. More bloating. More discomfort.
You're not doing it wrong. You're taking
the wrong kind of fibre for a sensitive gut.
Why fibre backfires
More fibre isn't the problem. The type of fibre is.
Most fibres ferment fast once they hit your gut. That fast fermentation produces gas quickly. On a sensitive gut, that's the bloating and cramping that makes people quit within a week.
The fibres in a lot of supplements are the fast-fermenting kind. Coarse bran fibres are rough on the gut wall. Neither is built for someone who already reacts to what they eat.
The fix isn't less fibre. It's a slower, gentler fibre: one that feeds your gut without flooding it with gas.
That's exactly what Sunfiber® is.
The fibre inside
Sunfiber® gets things moving. Gently.
It's a soluble fibre (partially hydrolysed guar gum) that ferments slowly. It feeds your good bacteria without the gas. And it works in both directions.
If you're backed up
↓
It softens and regulates, so going becomes easier and more predictable.
If you're loose
↑
It firms and slows things down, so your gut stops running the show.
Sunfiber® has been studied in clinical trials for constipation, for loose stools, and in people with IBS. It moves your gut toward normal, not toward one extreme. And it's certified low-FODMAP by Monash University, the people who created the FODMAP system.
The honest part: this is a daily fibre, not a laxative. It works gradually, not overnight. Most people feel the difference within two to four weeks of taking it every day.

What's inside
Two ingredients. Both doing real work.
No filler list. No proprietary blend hiding the doses. Just two actives, at doses that match the research.
7.0gper scoop
Organic Sunfiber®
Partially Hydrolysed Guar Gum
Sunfiber® certified logoRegularity, both ways. A slow-fermenting soluble fibre studied in clinical trials for both constipation and loose stools. It regulates toward normal, not one extreme.
Feeds the good bacteria. A true prebiotic: it selectively feeds Bifidobacteria and butyrate-producing bacteria, without the gas of harsher fibres.
Steadier blood sugar. As a soluble fibre it slows sugar absorption after eating, shown to blunt post-meal blood glucose, supporting healthy blood sugar.
Helps you feel full. It increases satiety after meals, supporting appetite control and healthy weight management.
500mgper scoop
Black Elderberry Extract
Sambucus nigra
Polyphenols for the gut-immune axis. A concentrated source of polyphenols that support the gut lining and the immune tissue around it. Most of your immune system lives in your gut.
Feeds a keystone bacterium. Research links black elderberry to higher levels of Akkermansia, a beneficial gut bacterium associated with metabolic and gut health.
Everyday immune support. Paired with a fibre studied for reducing cold-like symptoms when taken continuously. It's support you take daily, not a scramble once you're already run down.

I have tried many supplements over the years. Some I’ve stopped using because I didn’t notice a difference. I Will always aim to keep astaxanthin as part of my stack. I have noticed such an amazing change in my skin. My skin has always been good, but this has taken it to another level. I love this product! I particularly love the Biosphere brand as they use olive oil in the capsules, rather than seed oils. Really happy to support this NZ company.
Great product, I have been using it to help my eyes feel more comfortable ( post menopause) , they are definitely less scratchy than they were! I can’t wait to try the magnesium yet, it looks really good.
We both have the best sleep usimg this product. I am about to put in another order.
Lovely flavour and works really well.
I rely on 'Sleep' to help my sleep. Its a vial part of my evening ritual. I notice when I dont take it
Great for dry eyes. Best I've tried
Take this every night for restless legs and sleep . Alternate between the 2 flavours
Very good product but I did have to adapt it. I found taking it just before bed it would give me a hit of energy. So I no take it with dinner or just after around 7 and it gives my body time to process the ashwaganda. I still do have trouble sleeping but I do feel the nights I do sleep it’s a deeper sleep. I am going through a lot of stress and biological changes but I do feel it has helped just not as much as I hoped. The flavour is delicious and the customer service was awesome. I’m going to try the plain magnesium next time as I think ashwagandha not well suited to me
Great product - slept soundly :)
I’m loving this quality magnesium product from BioSphere as it has transformed the quality of my sleep.
I was sceptical but desperate when I started using Gut Support. After the first month, there hadn’t been a huge change, but I decided I was going to give it 2 months. Only a week into the second tub I noticed a definite change, and after not quite 2 months my system is so much calmer and more regular - the best it has been in nearly 6 years.
Nerve pain gone , deep sleeps after taking this . ! I am about to reorder , thanks guys 😍
This has been a game changer for me . It has eased pain and cramping at night . It promotes a feeling if calm and relaxation . I will never stop using this . Please buy it . I promise you won’t be sorry . Carolyn
Just love this product. I am on my third tin. I have been able to halve my blood pressure medication.
Sleep so much better and no more cramps
I won't need to ask for my money back. It works! The quality of my sleep has improved 10 fold.
Helps me stay asleep all night long
Prompt delivery and high quality. Noticed my eyesight not troubling me as much within a week.
It was a tough winter but this Biosphere Immune got us through.
I began taking this product 2 weeks ago to help with my sleep due to RLS and aching muscles due to injuries. Its great. I fall asleep well and sleep longer. I love the lemon lime flavour too!
Great quality astaxanthin and an easy addition to my daily supplement routine. I take it for its antioxidant, skin and general healthy-ageing benefits. Simple, well-dosed and no fuss. Very happy with it.
Awesome product!
Love it
Really like the flavour and taste, it encourages me to use it daily !
My husband and I have both been taking Biosphere Nitric Oxide, and we’ve been really happy with how we feel since starting it. We both feel so much better overall and have noticed a real difference in our general well-being and energy. It’s now become part of our daily routine, and based on our personal experience, we’re very pleased with it. It’s not often that we find a product that we both feel has made a noticeable difference, but this one has. We’ll definitely continue taking it!
Another one bites the dust! I’m really benefiting from taking this product every evening. I’m sleeping through the night, and waking refreshed. I would recommend this to anyone as a fuss free, easily digestible form of magnesium for settling your nervous system and allowing good sleep patterns.
Really like the Biosphere Magnesium. It's so helpful before and after hard physical work when I tend to get plagued with cramp. Alongside other salts & good hydration it's been great .Also very pleasant to drink. My wife also likes to use it at night for restless legs & to help relax. 😊
I love this product. I noticed an improvement in my skin. Looks and feels so much smoother.
I have systemic health issues and this is great for sleep, nerves and digestion (in a slow moving system). Great combination of types of magnesium. Easy to mix and take.
Great product. I take it every morning 🙂
Having parkinsons disease, exercise is very much my medication but has consequences the magnesium helps with the cramps and sleep quality which makes tomorrow better.
Love this product, after my first month I have far more mobility, energy and stamina, will be purchasing more...
I haven't gotten my very first bottle yet, but I will be ordering more. Capsules are easy to swallow, and makes it easy that need to take with food . Easy to remember with breakfast
It’s one of those things that you don’t you don’t know what you’ve got ‘til it’s gone! I was sleeping well and didn’t notice my gym recovery was good until I ran out of magnesium! Without it, my sleep is terrible and I’m sore for days after working out. Ordering more now!
On my second month of astaxanthin, not much change except a little more energy generally. Will give it a full three months.
I am so happy with my Astaxanthin . Can’t believe that it has worked so quick at pain relief . I have tried lots of other products in many years and I think this is the best thing I have tried . I have no pain and it so good . I hope this keeps up I have arthritis and and a few joint replacements so always in pain . Thank you
Awesome flavour magnesium for a massive day in the mountains!!!
Both flavours are nice and the powder mixes well. No longer getting night time cramps, so very happy with this. Will definitely be continuing with this product.
Awesome product.
Most supplements are formulated to a price point. Not to a result.
That's why so many fibre products underdose the one thing that matters, pad the tub with cheap filler, and leave you feeling nothing, or worse, bloated.
We do it the other way around. A full 7g therapeutic dose of Sunfiber®. Real Black Elderberry extract. No fillers. Third-party tested, in a GMP-certified USA facility.
It costs more to make. We're not going to pretend otherwise, and we're not going to cut the dose to hit a cheaper price.
You're paying for the dose that actually does the work.
60 days to feel the difference, or your money back.
Give it a proper run. Take it daily for up to 60 days. If your gut isn't in a better place, email us and we'll refund you. Love it or your money back. The risk is entirely ours, not yours.
Before you try it
Questions people ask
How long until I notice a difference?
It's a daily fibre, not a laxative, so it builds up rather than hitting overnight. Most people feel the difference within two to four weeks of taking it every day. The customers who stick with it daily are the ones who rave about it. Give it a proper run.
Will it bloat me like other fibres did?
That's the whole point of this one. Sunfiber® ferments slowly, which is what avoids the rapid gas that causes bloating with faster fibres. It's also certified low-FODMAP by Monash University, so it's specifically suited to sensitive, reactive guts.
When should I take it?
Any time of day that's easy to remember. One scoop mixed into 200ml of water, once daily. Consistency matters far more than timing. Pick a moment you'll actually stick to.
Can I take it every day, long term?
Yes. It's designed for daily use to keep your fibre intake topped up and your gut regular over time. It's food-based fibre, not a stimulant, so there's nothing to build a tolerance to.
Is it really low FODMAP?
Yes. It carries the Monash University Low FODMAP Certified™ mark. Monash are the researchers who developed the FODMAP system in the first place. It's the only product in our range with that certification.
What's it sweetened with?
Monk fruit extract: natural, no calories, and low-FODMAP. No sugar alcohols (no erythritol, sorbitol or the like), which are a common trigger for the exact bloating you're trying to avoid. Natural Black Elderberry flavour, and it mixes clear.
Get regular. Without the bloat.
A full 7g therapeutic dose of Sunfiber®, plus Black Elderberry. The gentle way to a gut that finally behaves.
