Best High Fiber Protein Bars (November 2026): 10 picks from ALOHA and Quest, from vegan everyday snacks to keto-friendly bars with up to 20g of protein.

Most protein bars are built around one number. Some print 20g of protein on the front and carry only a few grams of fiber, so you are hungry again in an hour. Others lean on fiber and deliver 6g of protein, which makes them closer to a cereal bar than a real snack. Add sugar, sweeteners, dairy or plant protein, and texture that ranges from soft and chewy to dry and chalky, and the wrong box is easy to buy. The Best High Fiber Protein Bars depend on which of those numbers you refuse to compromise on.
The short answer: the ALOHA Peanut Butter Chocolate Chip suits most people who want 10g of fiber and 14g of protein from organic, plant-based ingredients. The Quest Oatmeal Chocolate Chip suits anyone who wants 20g of protein and 1g of sugar in a soft, cookie-style bar, and the Fiber One Caramel Nut Chewy suits those who want a light, chocolate-coated fiber snack with 2g of sugar. The rest of the list covers vegan variety packs, keto-friendly options, a low-calorie bar and two KIND Protein MAX boxes.
TL;DR: top picks at a glance
- Best overall: the ALOHA Peanut Butter Chocolate Chip, with 10g of fiber and 14g of plant-based protein per bar and only 5g of sugar.
- Best for protein and low sugar: Quest Oatmeal Chocolate Chip, 20g of protein, 1g of sugar and 5g of net carbs.
- Best for a light snack: Fiber One Caramel Nut Chewy, at least 20% of the daily value of fiber and 2g of sugar in a chocolate-coated bar.
- Best for variety: TRUBAR Vegan Variety Pack, 11g of fiber and 12g of plant protein across three flavors.

What sets the ALOHA Peanut Butter Chocolate Chip apart is how it earns its fiber. Rather than leaning on a long list of isolated additives and artificial sweeteners, it builds the bar from organic peanuts, pumpkin seeds and plant proteins. The result is a bar that reads like food, with a sweet-and-salty peanut butter and chocolate chip flavor. That clean approach is the main reason it takes the top spot.
The numbers are strong without being extreme. Ten grams of fiber is close to what the TRUBAR bars deliver and clearly ahead of the 8g in the IQBAR Banana Nut and the 7g in the Wonderslim Fluffy Nutter. The protein is the compromise: 14g is respectable for a plant-based bar but well short of the 20g in the No Cow Chunky Peanut Butter. If your priority is the highest protein count, that bar is the better fit.
It is also not the lowest-sugar choice. Readers who need to hold sugar near 1g should look at the Quest Oatmeal Chocolate Chip or either KIND Protein MAX box instead. Where ALOHA wins is the middle ground: moderate sugar, high fiber, organic ingredients and no sweetener substitutes.
Texture is the one risk. Buyers who prize a soft, cakey bite sometimes find these firmer or drier than expected, so it is best stored at room temperature away from heat and eaten fresh. Those who want a guaranteed chewy, cookie-like texture will be happier with the Quest bar.

Pros:
Cons:
Best for: Low-carb eaters and gym-goers who want a soft, dessert-like bar with 20g of protein and almost no sugar.

The Quest Oatmeal Chocolate Chip is the most balanced bar for readers who want protein first and fiber close behind. Its 20g of protein matches the No Cow and KIND bars, but it adds 12-13g of fiber and a soft, cookie-style bite that the KIND boxes struggle to deliver. It also costs nothing in sugar terms, at 1g with no added sugars.
The trade-off against the ALOHA bar is the protein source. ALOHA is vegan and organic, while Quest uses dairy-based protein. If you avoid dairy, skip Quest and go for the No Cow Chunky Peanut Butter, which matches the 20g of protein from plants. If dairy is fine, Quest's softer texture and lower sugar make it the more indulgent daily bar.
It also comes in Chocolate Brownie and Cookies & Cream, which makes it easy to rotate flavors without changing brands. The caution is quality control: because freshness complaints exist, it is better bought in a pack you will finish within a few weeks than stockpiled.

Pros:
Cons:
Best for: Anyone who wants a low-sugar, chocolate-coated fiber snack between meals and does not need 20g of protein.

The Fiber One Caramel Nut Chewy is the outlier in this list. Where the Quest and No Cow bars target gym-level protein, this one aims at the person who wants more fiber in an everyday snack and treats protein as a bonus. Six grams is a modest figure, and the bar should be judged as a fiber snack, not a meal replacement.
Its strengths are sugar and calories. Two grams of sugar sits close to the IQBAR Banana Nut and well below the 5g in the ALOHA bar. The caramel and chocolate coating keep it satisfying for readers who find denser bars like the Quest or No Cow chalky.
It is the wrong choice for anyone training hard or replacing a meal. In that case the Wonderslim Fluffy Nutter, with 15g of protein and 7g of fiber at 160 calories or less, gives more nutrition per bar. Fiber One makes sense when the goal is a light, sweet, controlled snack.

Pros:
Cons:
Best for: Plant-based snackers who want a high-fiber bar in several flavors and do not need 20g of protein.

The TRUBAR Vegan Variety Pack answers a practical problem: most boxes here are a single flavor, and a dozen identical bars gets tiresome. This pack mixes peanut butter, macchiato and cookie dough, so you can find a favorite before committing to a larger order of the PB&J bar below.
Its nutrition is steady rather than extreme. Eleven grams of fiber and 12g of protein make it a closer match to the TRUBAR Pb & Jelly than to the protein-heavy bars. Buyers describe it as filling and clean in its ingredients, which suits readers who avoid sugar alcohols and want something they can fully pronounce.
It is the wrong pick for anyone chasing protein. For 20g from plants, the No Cow Chunky Peanut Butter is the clear alternative.

Pros:
Cons:
Best for: Keto and low-sugar eaters who want a banana nut flavor and a short, tested ingredient list.

The IQBAR Banana Nut is the pick when sugar and net carbs matter more than raw fiber. Its 2g of sugar comes from real banana, and the soft, slightly crunchy texture avoids the chalkiness that some protein bars suffer from. The bar is vegan, dairy-free, non-GMO and kosher, so it covers a wide range of diets.
Against the ALOHA bar, IQBAR cuts sugar by more than half but gives up 2g of fiber and 2g of protein. Against Quest, it is lighter on protein and fiber but friendlier to vegans. It is also available in a Natural option for those who prefer a different flavor.
Readers who want high fiber above all should look at the No Cow Chunky Peanut Butter or the TRUBAR Pb & Jelly instead.

Pros:
Cons:
Best for: Vegan snackers who want maximum fiber in a sweet, nostalgic flavor and can live with moderate protein.

The TRUBAR Pb & Jelly is the fiber-first member of the TRUBAR family. Compared with the variety pack, it adds one to two grams of fiber and focuses on a single, well-defined flavor. For readers who already know they like peanut butter and jelly, that makes it the better dozen to buy.
Its limitation is protein. Twelve grams is the same as the variety pack and well below the 20g in the Quest or No Cow bars. If protein matters equally to fiber, step up to the No Cow Chunky Peanut Butter, which offers more of both.

Pros:
Cons:
Best for: Calorie-conscious dieters who want a soft, sweet bar with 15g of protein and moderate fiber.

The Wonderslim Fluffy Nutter is built around calories, not maximum fiber. At 160 or fewer calories it undercuts the 190-calorie TRUBAR bars while delivering 3g more protein. For weight management, that combination is its main appeal.
When a sweet tooth is the real issue, some readers pair a bar like this with zero calorie candy to stretch through the afternoon, though it will not replace the protein and fiber that make this bar filling. If your goal is more fiber, though, the ALOHA, TRUBAR and No Cow bars all offer notably more.

Pros:
Cons:
Best for: Vegans and keto eaters who want the highest protein and fiber from plants and do not mind a firmer texture.

The No Cow Chunky Peanut Butter has the highest numbers of any bar here: 20g of protein, 14g or more of fiber and 1g of sugar. It matches Quest's protein and surpasses it on fiber, without using dairy. For vegans, that makes it the most powerful option.
The trade-off is texture. Where Quest is soft and cookie-like, No Cow can be dry and chalky. It is also available in Peanut Butter Chocolate Chip, Chocolate Fudge Brownie and Key Lime Pie, which may suit different tastes better.

Pros:
Cons:
Best for: Readers who want to sample KIND's 20g protein, low-sugar formula before buying a larger box.

The KIND Protein MAX Caramel Peanut Crisp pairs peanut flavor with 20g of protein and almost no sugar. It is the same bar found in the KIND variety pack, in a smaller four-bar format.
Readers managing blood sugar closely should also look at protein bars for diabetics, because this bar's 1g of sugar and filling profile fit that need but the fiber figure is unspecified. If you want confirmed fiber grams, the Quest Oatmeal Chocolate Chip is the safer choice.

Pros:
Cons:
Best for: Keto and low-sugar snackers who want 20g of protein in a 12-count box with two flavors.

The KIND Protein MAX Variety Pack is the more practical way to buy the KIND formula, since it gives twelve bars across two flavors. The numbers are identical to the single-flavor box: 20g of protein and 1g of sugar.
It loses ground to Quest and No Cow on texture and on stated fiber. If you want confirmed fiber alongside 20g of protein, choose the No Cow Chunky Peanut Butter or the Quest Oatmeal Chocolate Chip instead.
The core trade-off is between nutrition numbers and eating experience. The highest fiber and protein counts often come with a firmer, drier texture, while softer, sweeter bars usually give up one or the other. The right choice depends on your diet and how much chew you will tolerate.
Before choosing, check these project details:
Fiber ranges widely across this list. The No Cow Chunky Peanut Butter leads with at least 14g, followed by the TRUBAR Pb & Jelly at 12-13g, the Quest Oatmeal Chocolate Chip at 12-13g, the TRUBAR Vegan Variety Pack at 11g and the ALOHA bar at 10g. The IQBAR Banana Nut offers 8g, and the Wonderslim Fluffy Nutter 7g.
Some bars give fiber only as a daily value percentage, such as the Fiber One Caramel Nut Chewy, or do not list grams at all, as with both KIND Protein MAX boxes. If you track fiber closely, favor bars with a stated gram count. Raising fiber intake quickly can cause discomfort, so start with one bar a day.
Quest uses dairy-based protein, while ALOHA, TRUBAR, IQBAR and No Cow use plant proteins from sources like pea, brown rice and pumpkin seed. Twenty grams is the high-water mark, available from Quest, No Cow and KIND, while TRUBAR and IQBAR sit at 12g and Wonderslim at 15g.
Texture can affect how much of a bar you finish. Readers who struggle to chew firm bars may find a protein drink for seniors easier to manage than any bar here. For everyone else, the softer Quest and Wonderslim bars are the gentler options.
The lowest-sugar bars are Quest, No Cow and both KIND boxes at 1g, followed by IQBAR and Fiber One at 2g. ALOHA has 5g, and the TRUBAR and Wonderslim bars do not list a gram figure. ALOHA and TRUBAR avoid stevia and sugar alcohols, which matters for those who react to them.
If a sweet tooth is the main driver, remember that a bar must also deliver protein and fiber to earn its place. A standalone product like zero calorie candy serves a different purpose from a bar meant to fill you up.
Texture is the most common complaint across this category. Quest and Wonderslim lean soft and chewy, while No Cow and some KIND bars skew dry. The ALOHA bar sits in the middle, with feedback ranging from soft to chalky.
Pack size shapes how much you can test. The four-bar KIND Protein MAX Caramel Peanut Crisp is the cheapest way to trial a flavor, while the TRUBAR Vegan Variety Pack and KIND Protein MAX Variety Pack spread twelve bars over several flavors. Single-flavor dozens suit people who already know what they like.
A bar with 7g or more of fiber is generally considered high fiber. The No Cow Chunky Peanut Butter leads with at least 14g, while the ALOHA Peanut Butter Chocolate Chip offers 10g. The Wonderslim Fluffy Nutter, at 7g, is the lowest stated figure.
Quest Oatmeal Chocolate Chip, No Cow Chunky Peanut Butter and both KIND Protein MAX boxes each provide 20g of protein. Of those, Quest and No Cow also list at least 12g of fiber. The Fiber One Caramel Nut Chewy has the least at 6g.
Several are. ALOHA, TRUBAR, IQBAR and No Cow are all vegan, using plant proteins. Quest uses dairy-based protein, so it is not vegan.
Quest, No Cow and both KIND Protein MAX boxes list 1g of sugar. The IQBAR Banana Nut and Fiber One Caramel Nut Chewy each list 2g. ALOHA has 5g, and the TRUBAR bars do not specify.
Raising fiber intake quickly can cause gas or discomfort, especially with bars at 10g or more such as ALOHA or No Cow. Starting with one bar a day and drinking water helps. A lighter option like the Fiber One Caramel Nut Chewy is gentler for sensitive readers.
IQBAR Banana Nut lists 3g of net carbs and is labeled keto-friendly. No Cow and both KIND Protein MAX boxes are also described as keto-friendly with 1g of sugar. Quest has 5g of net carbs, which fits many low-carb plans.
Best High Fiber Protein Bars for most snackers start with ALOHA Peanut Butter Chocolate Chip: 10g of fiber, 14g of plant-based protein and 5g of sugar in an organic, vegan bar with no stevia or sugar alcohols. Its main weakness is texture, which some find dry, and a sugar count higher than the 1g bars.
For alternatives by use case, the Quest Oatmeal Chocolate Chip suits anyone who wants 20g of protein, 12-13g of fiber and 1g of sugar in a soft, cookie-style bar and can eat dairy. The Fiber One Caramel Nut Chewy is the lighter option for a chocolate-coated snack with 2g of sugar and little protein. The TRUBAR Vegan Variety Pack gives three plant-based flavors with 11g of fiber.
For specialist needs, the IQBAR Banana Nut fits keto eaters with 3g of net carbs, the TRUBAR Pb & Jelly fits fiber-first vegans, the Wonderslim Fluffy Nutter fits calorie control and the No Cow Chunky Peanut Butter offers the highest protein and fiber from plants. The KIND Protein MAX Caramel Peanut Crisp and KIND Protein MAX Variety Pack suit low-sugar eaters who want 20g of protein. If you are still undecided, start with the ALOHA bar for balance or the four-bar KIND box for a low-commitment test.
