recommend this productLeading the functional fiber pack, our organic guar bean fiber (Cyamopsis tetragonoloba, as Sunfiber®) is a gentle (and low FODMAP) soluble plant fiber with powerful prebiotic and postbiotic benefits. One of the most extensively researched fibers, Sunfiber® is clinically shown to deliver multidimensional GI support—promoting regularity, healthy stool form, gut transit time, satiety, healthy blood sugar and cholesterol levels, and gut microbial balance.*
Organic New Zealand green kiwifruit powder (Actinidia chinensis var. deliciosa, as Actazin®) delivers prebiotic fiber to nourish the good bacteria in our gut. Our versatile kiwi offers many beneficial plant compounds including soluble and insoluble fibers, native polyphenols, and actinidin (a protein-digesting enzyme). Actazin® is clinically shown to improve digestion, bloating, gastric comfort, and laxation—gently promoting regular and easy bowel movements.*
Our mighty mushroom trio features a blend of organic whole reishi (Ganoderma lucidum), maitake (Grifola frondosa), and oyster mushrooms (Pleurotus ostreatus), as TriCelium™. Delivering unique beta-glucan soluble fibers, these functional fungi provide dual benefits for digestive health and immunity. TriCelium® is also scientifically shown to support production of postbiotic short-chain fatty acids (SCFA), bioactives known to nurture gut barrier integrity and function.*
Complementing our organic plant fibers, Bacillus subtilis ATCC122264 (as Sporevia™) is a unique and resilient spore-forming probiotic strain. Our clinically-researched 5 billion CFU dose of Sporevia™ provides an efficacious and durable probiotic clinically shown to promote beneficial gut microbes, combat intensity and frequency of gas and bloating, facilitate stool consistency, enhance abdominal comfort, and support vitality and well-being.*
Sunfiber® supports regularity, healthy stool form and transit time, satiety, healthy blood sugar and cholesterol levels, and gut microbial balance.* Each scoop provides 7 g of organic guar fiber as Sunfiber®, with 6 g of total dietary fiber listed on the nutrition panel.* It is a low-FODMAP soluble fiber.
Actazin® supports digestion, gastric comfort, laxation, less bloating, and regular, easy bowel movements.* Each scoop provides 600 mg of organic New Zealand green kiwifruit powder as Actazin®, a labeled source of soluble and insoluble fiber, polyphenols, and actinidin.
The ingredients complement the formula’s fibers in distinct ways: TriCelium™ supports short-chain-fatty-acid production and gut-barrier integrity, while Sporevia™ supports beneficial gut microbes, stool consistency, abdominal comfort, and less gas and bloating.* Each scoop combines 500 mg of organic reishi, maitake, and oyster mushrooms as TriCelium™ with 5 billion CFU of Bacillus subtilis ATCC122264 as Sporevia™.

You should check out the ingredients. This isn’t your average fiber supplement powder. It has prebiotic, probiotic AND postbiotic support! It’s also USDA organic and WORKS like a charm.
Love the organic ingredients. Tasteless and blends beautifully with morning coffee.
Best of all… good amount of fiber and keeps you regular. All around a very good quality product.
Thank you MBG!
PS: I love your website/articles & podcasts, such reliable information.
Organic fiber+with prebiotic support, blends well in food. I usually add a scoop to the bottom of my cereal in the mornings. Does not taste bad and keeps my metabolism working well. Recommend mindbodygreen products.
This fiber is easy to use, it mixes easily with your coffee or other beverage, as well as yogurt, cereal or soup. It helps ensure that I get my daily fiber, along with fruits and veggies.
For many reasons, mainly due to the need for prolonged antibiotics years ago, my guts have been sensitive. This fiber plus probiotic/prebiotic mix has REALLY helped so much! I am very grateful, as I have tried many different concoctions over the years. I mix it with some Liquid IV (only 1/2 packet) to add electrolytes and a little flavor.
Purchased to increase daily fiber. Very beneficial and easy to add to water in AM. And their probiotics in the evening. Will continue to use both.
Start taking this fiber to improve my cholesterol level. I will have it checked in couple months! Hope and pray will help 🙏🏼
This fiber supplement is one of the best I’ve tried! It dissolves easily and doesn’t become overly thick like many others. I started using a fiber supplement based on high cholesterol levels due to genetics and menopause so I appreciate a great product that is easy and enjoyable to use daily!
Mixed well in liquids without gelling. I love that it is a fairly neutral flavor. I just mix in water and drink it down. Mixes fine with coffee. In tea, because the flavor of tea is more subtle, the fiber changes the flavor. I like the fiber straight up.
I've been using this for 4 months and my detailed cholesterol markers have all improved - Apolipoprotein B, the sticky plaque #s, etc. Highly recommend.
Love this product. Adding just the right amount of fiber. With the prebiotic support I don't need any other supplement for the day.

I've been taking the organic fiber+ with prebiotic support for about 20 days or so. It's hard to tell if it's actually doing much on its own, or if it's just complimenting my overall diet and supplementation regimen. I like the ingredients and my next bag has already been shipped, so I'll continue taking it until it's gone. However, it's very pricy and paying $50/20 days for a fiber powder is a bit ridiculous. I will say that it mixes very well in just about anything - hot or cold. It's completely flavorless and has no texture at all once mixed. Granted, I've never mixed it in pure liquid (only smoothies, yogurt, oatmeal) so not sure how it does with that. However, I can't get past the extremely high price. So for that reason I'll probably search for a similar replacement that is more budget friendly. It a shame because I really like the MBG brand but just can't justify spending that much for something that is just a supplementation not necessarily a game changer. For me, at least.
fiber doesn't always taste great but this fiber has no distasteful quality. it is good for heart and G.I. health. soluble fiber sweeps away fatty deposits in the gall bladder, I think. can't go wrong with this organic clean product.
This is a great product and delivers exactly what it states it will do. In fact, I love all of the products I’ve been using so far. Having said that, I feel the prices are very high and not in reach for most people to take advantage of. This is why I’m going to need to discontinue my subscriptions to my products. Unless the prices come down for these products, I will not participate in purchasing them any longer.
Hi Julie, we're so happy to hear that you've been enjoying organic fiber+ with prebiotic support and seeing all of its great benefits! We care deeply about where our ingredients come from and only partner with suppliers whose practices emphasize quality, science, and responsibility. We strive to make every product as accessible as possible, but this commitment to high-quality ingredients and sustainable packaging does incur higher production costs.
To further explain, we’ve partnered with industry leading manufacturers of science-backed nutritional supplements, to create our mindbodygreen supplements+ line. Our products go through 4 rounds of advanced analytical testing across the total supply chain (from the raw ingredients to the final product) at state-of-the-art labs. Many competitors test only once or twice. Our products are tested for precision, potency, and purity from contaminants like microbes, heavy metals and pesticides.
From our hero ingredients to the excipients in our "Other ingredients" list, source, efficacy, safety, and innovation are front of mind. We partner only with suppliers whose practices emphasize quality, science, and responsibility. We are equally meticulous about what's excluded from our formulas. Our "no list" considers the individual by intentionally saying no to ingredients that can cause challenges to those with key sensitivities or allergies. Our manufacturers have sterling records of compliance with the Current Good Manufacturing Practice (cGMP) regulations set and monitored by the U.S. Food and Drug Administration. You'll also find USDA Organic certified products within our line of supplements.
That said, our team will be in touch with you regarding discount opportunities and we hope you will continue to keep mindbodygreen as a part of your wellness regimen. All the best. - mindbodygreen
I was surprised at how small the portion is on this for the price! I think I paid $50!! Trying to return it but their system only allows a store credit to buy something else!! I have way too many vitamins as it is! That I don’t take.
Hi Kathryn, thank you for taking the time to share your feedback with us, and we're sorry to hear of the trouble with our returns portal. Our support team will be in touch, as we'd love to make this right for you and provide you with a discount opportunity. All the best. - mindbodygreen
Add it to water, infuse it into tea, blend it in a smoothie, incorporate it into baked goods, or mix into your coffee or shake! Our organic fiber+ with prebiotic support powder disperses easily in hot and cold liquids and is stable at high temperatures. We recommend you mix one scoop with 8-10 fluid ounces of your preferred beverage or meal daily or as recommended by your health care practitioner. If pregnant, consult your health care practitioner before using this product. This is a family-friendly product, for children ages 4 (under adult supervision) and older. Use only if bag is sealed. Store tightly sealed in a cool, dry place.
If you have specific food sensitivities or allergies to any of the ingredients in this product (guar bean fiber, mushrooms, kiwifruit), then you’ll want to avoid use or consult your health care practitioner before using this product. The formula is low in lectins and FODMAPs, but can still contain trace levels. For individuals with sensitivities to key ingredients, you’ll want to partner with your healthcare provider before using this or any supplement product.
That’s honestly up to you! You can personalize when to take organic fiber+ with prebiotic support at any point in the day. Some choose to take advantage of this comprehensive digestive and regularity support supplement in the morning with preferred beverage or meal, while others fold it into their afternoon/evening nutrition ritual. We do recommend consulting with your health care practitioner when incorporating organic fiber+ with prebiotic support into your daily regimen, as fiber can interfere with absorption of certain active ingredients.*
While organic fiber+ with prebiotic support is formulated to be gentle on the gut and help address fiber gaps, some individuals increasing daily fiber intake whether through diet or supplementation can experience a digestive adjustment period with increased doses. Since fiber gaps are so common in our nation, the addition of fiber in one’s daily nutrition ritual is paramount. Because of the potential in some individuals for gas or bloating, we recommend personalizing your daily fiber intake by easing into it, paying attention to bodily cues, and drinking plenty of fluids throughout the day!
Fiber is an essential nutrient. That means our bodies cannot make it, so we must consume it daily! Fiber plays a critical role in promoting a healthy gut microbiome, and whole-body wellness starts in the gut. Fiber is also vital for a healthy and balanced diet. Great sources of dietary fiber (exclusively found in plants) include fruits, vegetables, whole grains, legumes, seeds, and nuts. Sufficient fiber intake provides a wide range of benefits including promoting regularity, gastrointestinal (GI) health, immunity, gut barrier function, growth and balance of friendly bacteria in the gut, satiety, healthy blood sugar and cholesterol levels, and more!*
Unfortunately, fiber intake represents a serious problem as a major dietary gap for the overwhelming majority of Americans. Approximately 95% of Americans are failing to meet their daily fiber needs from diet alone (yikes). Therefore, consuming a dietary pattern that is plentiful in fiber-rich plant foods is of utmost importance. To complement your diet (since daily fiber needs are so high—21 to 38 grams per day), a clean and high-quality fiber supplement is a smart strategy to help fulfill daily fiber goals and reap the many health benefits that accompany sufficient fiber intake.
Along with providing you and your family with an excellent source of functional fibers in each scoop, mbg’s organic fiber+ with prebiotic support is a vegan, USDA certified organic, plant-powered synbiotic blend that delivers science-backed prebiotic, probiotic, and postbiotic-promoting ingredients from organic guar fiber (as Sunfiber®), organic New Zealand green kiwifruit powder (as Actazin®), organic mushroom blend including organic reishi, maitake, and oyster mushrooms (as TriCelium™), and targeted probiotic Bacillus subtilis ATCC122264 (as Sporevia™).*
These gut-centric powerhouse ingredients are clinically shown to nourish your gut barrier and microbiome, aid digestion and GI motility, ease bloating and gas, promote satiety, and support healthy blood sugar and cholesterol levels. Each scoop of organic fiber+ with prebiotic support directly supports your daily fiber needs while providing a unique and effective synbiotic (prebiotic + probiotic) combination of powerhouse ingredients to help keep your GI tract on track (all while being gentle on the gut).*
A healthy and balanced gut microbiome is essential for overall health and wellness, and the composition of our gut microbes (i.e., the abundance and diversity of good bugs in our GI tract) is a critical component of this. That’s where prebiotics, probiotics, and postbiotics come in–promoting balance of healthy microflora, the main pillars of supporting a thriving gut.
Probiotics are live, beneficial microorganisms that lend aid to host microbes residing in our gut. While probiotics are beneficial bacteria, prebiotics (typically from high-fiber sources) serve as food for these beneficial bacteria. Basically, probiotics are major team players in the goal of supporting optimal gut health, while prebiotics give these players the food and fuel they need. Synbiotics bring the two together, combining prebiotics and probiotics. This confers synergistic and complementary actions to support a healthy gut.
Postbiotics is a newer term. They are the metabolites or bioactive compounds produced from friendly probiotic activity in the gut. Postbiotics are beneficial for digestive and immune health. Short-chain fatty acids (SCFAs) including butyrate, acetate, and propionate are some of the most commonly recognized postbiotics. Butyrate in particular is shown to have important immunomodulatory activity and supports healthy gut barrier integrity.
Our organic fiber+ with prebiotic support features six powerhouse ingredients delivering pre-, pro-, and postbiotic support in a plant-powered synbiotic blend. Prebiotic and postbiotic-supporting ingredients include organic guar fiber (Sunfiber®), organic mushroom blend (reishi, maitake and oyster mushrooms as TriCelium™), and organic green kiwifruit (Actazin®), plus the unique probiotic strain Bacillus subtilis ATCC122264 (Sporevia™). This ultimate, synbiotic fiber supplement delivers clinically-backed ingredients at full-potency doses to promote a healthy intestinal environment and gut microbiome for you and your family, in one easy daily scoop.*
Fiber, broadly described, is a type of complex carbohydrate that your body cannot fully digest. While there are many sources of fiber, there are two basic categories–soluble and insoluble. While soluble fibers (sometimes referred to as viscous fibers) and insoluble fiber (also referred to as bulking fiber) are both important and have some shared functions, they are handled differently by the body and also confer unique health benefits.
Soluble fiber (found in food sources such as oats, chia and flax seeds, nuts, legumes like beans and lentils, mushrooms, berries, and other fruits), dissolves readily in water and helps slow the digestive process. This speed control supports absorption of certain nutrients (such as carbohydrates) in the body and aids in the balancing of blood sugar levels. Select soluble fibers are also prebiotic, meaning they serve as food for beneficial bacteria in the gut. Prebiotic soluble fibers are beneficial for our GI tract and overall gut health, as the good bugs (i.e., healthy bacteria residing in our intestines) that feed on them produce helpful metabolites such as short-chain fatty acids (SCFAs) including butyrate, acetate, and propionate (aka postbiotics). These short-chain fatty acid byproducts are also known to support healthy gut integrity and barrier function.
On the other hand, insoluble fiber (found in food sources such as avocados, wheat, seeds, beans, and fruits and vegetable skins), does not readily dissolve in water and works its way through the digestive system intact. Insoluble fiber has laxative properties and provides “bulk” to stool, promoting healthy stool form, regular bowel movements, and overall digestive function. Insoluble fiber acts metaphorically as a “broom” in the digestive process.
Our organic fiber+ with prebiotic support delivers six powerhouse ingredients for pre-, pro-, and postbiotic support, including both soluble and insoluble fiber sources. Together, organic guar fiber, organic mushroom trio (reishi, maitake, and oyster), and organic green kiwifruit provide an excellent source of plant functional fibers in each scoop. And don’t forget the bonus probiotic Bacillus subtilis. This is your #1 daily ritual for the all-important #2.*
Our high-quality formulas are delivered in premium, sustainable, and recyclable packaging (recyclable amber glass bottles and jars, recyclable bags, and recyclable cardboard shipping boxes made from 100% recycled paper). Always looking towards the latest innovations, we carefully and intentionally source our eco-friendly packaging to prioritize the environment, but also to protect the premium ingredients in our capsules, gelcaps, and powders (i.e., vitamins, minerals, botanicals, peptides, probiotics, bioactives) from UV light degradation. This is pivotal to ensure quality standards throughout the lifecycle of the product.
Unfortunately many refillable bags or containers do not provide the same protection and stability for our ingredients as our amber glass (bottles, jars) and PET bags achieve. What's more, the product-specific manufacturing information (i.e., specific identifiers such as the lot and date) stamped on each product would be lost when the customer discards the refill packaging, as is customary. That lost information would not enable us to comply with a variety of very important FDA regulations specific to dietary supplements (e.g., cGMPs, adverse event reporting, etc.), and regulatory compliance is something that mindbodygreen respects and prioritizes. From an additional safety standpoint, there are also microbial contamination concerns with refillable vessels over time. Thank you for your consideration as to why we have thoughtfully curated our packaging in the way we do.
Yes. Organic fiber+ with prebiotic support is also USDA certified organic, GMO-free, soy-free, dairy-free, and major food allergen-free.
