Pros:

It is both gluten-free and dairy-free

Has no fillers whatsoever

Provides you with several nutrients and essentials

Cons:

Could taste better

As the name of this next entry suggests, it is organic. However, as several buyers have claimed, those with sensitive stomachs may want to veer off this path as this powder can be difficult to consume.

Read more

Nutrients and Essentials
Along with nine grams of fiber per serving, which is great, this also provides you with seven grams of protein, probiotics, and omega 3 fatty acids. Plus, this is made with 15 RAW organic superfoods.

Capacity
Per day, you should take one scoop of this substance. In regard to the size, you can choose between small, large and a 1.31-pound bottle.

Allergens
Given the fact that this is certified USDA organic, it is free of gluten and dairy. And, yes, it is considered a vegan product.

Flavor and Texture
For sure, based on vast consumer feedback, this can be a hassle to take frequently. The reason for this is the rough and solid texture as it will become solid very quickly.

Unwanted Additives
Have peace of mind knowing that there are no artificial sweeteners, synthetic nutrients, isolates, preservatives, and fillers whatsoever.

Overall
While it can be hard to get down, this organic option provides some of the best health benefits of any supplement in the world. That will be worth it for most people.

Pros:

100 percent natural

It is both clear and tasteless

It can be added to any of your foods and beverages

Cons:

Some users claim it has had little effect

Outside of being 100 percent natural, arguably the best aspect of Benefiber’s powder is the fact that it is tasteless. Some powders can be ruined by taste alone so it is reassuring that this is not an issue.

Read more

Nutrients and Essentials
This is a 100 percent natural dairy prebiotic dietary fiber powder supplement.

Capacity
There are several different size options to choose from, so that is a bonus. You can select either a 5.4-ounce, 8.7-ounce, 17.6-ounce, or 26.8-ounce bottle.

Allergens
Here is the deal here; this actually does contain gluten but it contains less than 20 parts per million. So, by the FDA definition, this can be considered gluten-free.

Flavor and Texture
Indeed, this is void of any taste and this means it can be added to your favorite beverages and foods. Plus, it will dissolve in most of the substances you put it in.

Unwanted Additives
As the product description points out, this is a 100 percent natural product so there is no worry about unwanted additives or preservatives.

Overall
As you can see from the customer feedback, a ton of buyers appreciate and love this supplement. Even though some buyers have claimed it has little effect, the vast majority agrees it is excellent.

Pros:

It is gluten-free

This is doctor recommended for over 50 years

It helps support diabetes management

Cons:

Could taste better

As great as this formula is from Konsyl Pharmaceutical, many of you will simply not be able to get over the consistency and taste. Then again, this is always subjective.

Read more

Nutrients and Essentials
Konsyl Pharmaceutical included six grams of pure psyllium fiber into their formula.

Capacity
This is a 15.9-ounce bottle with 75 doses in total. Given that this is recommended for people over 50 years in age, a half-a-teaspoon a day could be feasible.

Allergens
The main aspect of this formula is that it is gluten-free. With the elderly, in specific, you do not want to mess around with food allergies.

Flavor and Texture
This is a new product from Konsyl Pharmaceutical and some users have reported that it is much finer. Also, as mentioned, the consistency and taste can be a little overbearing.

Unwanted Additives
There are no additives and no sugar or even substitutes for sugar included in this formula. Also, this product is gluten-free.

Overall
For the older generation, this is an ideal option. Then again, the overbearing texture, which is almost similar to drinking pencil shavings, maybe too much.

Pros:

It is also available in capsules

One serving provides you with 2.4 grams

It is the number one doctor recommended brand

Cons:

Could taste better

Now, this next option is a powder but be aware that this same brand is also available in capsules and single serve packets. But, for the record, this is covering the fantastic powder version.

Read more

Nutrients and Essentials
The secret to the success of this formula is the 100 percent inclusion of natural psyllium fiber.

Capacity
The bottle of this powdered version comes in 48 doses. Now, you can take up to three servings daily and one serving consists of one rounded tablespoon.

Allergens
At least for the powder version, and this is probably the same for the capsules, there is little concern for those of you with common food allergies.

Flavor and Texture
Some users have criticized this powder for tasting bland and also being a bit chalky. Also, it is not uncommon for the substance to clump together at the bottom of your glass.

Unwanted Additives
It is interesting to note that Metamucil does use aspartame as a sweetener in their formula. Also, there are eight grams of sugar per one teaspoon of substance.

Overall
What is so cool about this option is if you do not like powder, Metamucil has other options available for you. With what it provides you with, it is almost a no-brainer.

Pros:

Available in multiple count tablets

There are no sugars or extra flavorings

It is non-toxic and non-allergenic

Cons:

Pills are quite large

When looking at the glass half-full here, there is little to gripe about it. However, turn that glass upside down and you begin to analyze that the effectiveness of this option has been questioned.

Read more

Nutrients and Essentials
The fiber that is included here is methylcellulose and this is non-toxic and also non-allergenic. Plus, this is not going to cause excess gas based on laboratory testing.

Capacity
Due to the fact that each caplet does not contain too much fiber, you may need to take up to four at a time. But, they do come in small, medium, and large sizes.

Allergens
As mentioned, the fiber used in this formula is non-allergenic and does not feature gluten, either.

Flavor and Texture
Though these are less messy to make than powdered versions, the caplets are quite large and can be hard to swallow at once. Still, you need not worry about the flavor or texture.

Unwanted Additives
Just the straight stuff here ladies and gentlemen. There are no sugars, fake sugars or any flavorings whatsoever.

Overall
The rather low intake of fiber per caplet, only one gram, does hurt this option a bit. But, the methylcellulose type that this provides is certainly terrific.

Pros:

Supports your digestive track

You also get a good dose of vitamin D and calcium

Each tablet contains inulin

Cons:

When chewing the tablets, the texture can take some getting used to

As compared to the other entries on this list, these chewable fruity tablets could just be the most delectable. Sometimes, you forget that these are providing health benefits for you.

Read more

Nutrients and Essentials
This is made of inulin and this is a 100 percent natural fiber that is found in fruits and vegetables. In addition, you also receive a healthy dose of vitamin D and calcium.

Capacity
In the bottle that you receive, there are 90 tablets. Two tablets will provide you with three grams of fiber, so keep that in mind.

Allergens
These are simply just chewable fruity tablets and because of this, there is no gluten.

Flavor and Texture
Again, these are chewable tablets and what you receive is an assortment of flavors including grape, green apple, and strawberry. Some users, admittedly, may not like the sweet tart-esque flavor, though.

Unwanted Additives
It is interesting to note that there are some artificial flavors present here. They include vitamin D3, Blue 2 lake and Red 40 lake.

Overall
Outside of the fact that this is ideal for adults, it is also nice for children as these are chewable tablets that taste like fruit. But, do note that the texture can take some time to get accustomed to.

Helps to restore balance in the intestines

Cons:

Some buyers claim it is not the most effective

While the last entry was a powder, this one is consistent of caplets. With these, you get a strong amount of fiber per dosage and they are also very easy to swallow.

Read more

Nutrients and Essentials
In addition to the fact that you get four to six grams of fiber per a dose of two caplets, you also get 140 milligrams of calcium and 10 milligrams of magnesium.

Capacity
Per bottle, there are 140 tablets. But, you can buy this in either a pack of two or three, if you desire. Also, as an adult, it is advised you take two tablets a day.

Allergens
Those with common food allergies should not have too much to worry about here. In specific for Celiac disease, there does not appear to be gluten.

Flavor and Texture
Due to the fact that this is comprised of just caplets, you do not need to worry about dissolving them in water. Instead, you simply swallow them with a glass of water to avoid potential choking.

Unwanted Additives
Based on the product label, it appears that there are no unwanted additives.

Overall
A lot of consumers will look to avoid powder-based options due to the mess and the texture. If you are looking for tablet-based, this option could be the best you will find.

Cons:

Can clump up when it is mixed

This is another option that is unflavored and it can be added to your favorite beverages. However, also noteworthy is it has a sensational six sources of fiber per serving.

Read more

Nutrients and Essentials

Unwanted Additives
One other benefit to this being unflavored is you know that no artificial flavors and sweeteners were added in the developing process.

Overall
Without question, this is one of the better sources out there due to the amount of fiber you receive per serving. Plus, with this being unflavored, it can be mixed into your favorite drinks.

Cons:

Both the taste and the texture could be improved

This specific option, which is comprised of psyllium husks, is ideally recommended for people with low carb eating diets. Plus, there are absolutely no additives in this formula.

Read more

Nutrients and Essentials
As with some of the other options on this list, this powder from Yerba Prima is pure psyllium fiber which has its health benefits and is ideal for low carb diets.

Capacity
Each bottle has 12 ounces of substance in it. You can either get a pack of two, three or four. Keep in mind, though, it is recommended taking one to three servings a day and there are 68 servings in one bottle.

Allergens
From the looks of it, it does not appear that there are too many common food allergies to deal with here.

Flavor and Texture
Both the flavor and the texture of this powder are mediocre. The issue with the texture is how it dissolves in water as it can clump and stick to glasses.

Unwanted Additives
Again, as the product label indicates, there are no additives in this formula.

Overall
To be honest, this option has one of the most common flaws that supplements tend to have. Of course, that is the texture. If you can get this down, you can get one of the better bang for your buck options.

Pros:

Cons:

Not the most versatile

Now, this one is interesting. These delectable treats are literally brownies and yes, they taste amazing. But, the best part is they do include 20 percent of the daily value of fiber you need.

Read more

Nutrients and Essentials
Believe it or not, this actually does provide you with a solid amount of fiber. As mentioned, it gives you 20 percent of your daily recommended intake.

Capacity
One box of brownies contains 12 bars. Given the fact that these suckers can certainly be addictive, you may find yourself buying multiple boxes.

Allergens
Without a doubt, this is not ideal for buyers with common food allergies. It includes just about everything including wheat, soy, eggs and milk.

Flavor and Texture
It is not hyperbolic to claim that this is easily the best tasting option on this list. It is a fudge brownie with real chocolate chips and a drizzled topping.

Unwanted Additives
The flavor and ingredients of these brownies are really natural. Indeed, there are no colors, flavors, or sweeteners included from artificial sources.

Overall
Sometimes, it is crazy when you realize that some foods that provide health benefits taste good. This is the instance with these fudge brownies and yes, they are quite tasty.

Criteria Used for Evaluation

Effectiveness

Everyone is probably aware that it is recommended to have a certain amount of fiber intake daily. However, what you may or may not be aware of is that there are two types of fibers and loads of different subtypes. The two main types are soluble and insoluble. The former binds with fatty acids and will slow the digestion process to release blood sugars more slowly into the body. As for insoluble, these help hydrate and move waste through your intestines. These will help to prevent constipation.

But, within insoluble and soluble there are also loads of other subtypes. For example, two popular soluble types are psyllium and inulin. The former is ideal for helping lower your cholesterol and the latter will enhance your immune function. A popular subtype for an insoluble fiber is cellulose and this will help to reduce constipation and can also help with weight loss. All these types are beneficial, but certain ones may be more so for your needs than others. Oh, also, you can look for other essentials such as calcium, magnesium, and vitamin D.

Capacity

As a consumer, you always want to get the most out of your money. No one wants to invest in a product that really is not worth the money. In this instance, it is more complicated than it normally will be. Much like you would do comparing two different bags of snacks to ensure which one is offering more substance for the money, you need to address both the capacity and serving size of an option. Of course, it also depends on how much fiber is being provided per serving. But, here is an example of why this matters.

Let’s say that you invest in a bottle, with capsules in this example, with 100 capsules. If the daily recommendation is two and you abide by this, the bottle will last you 50 days and two people 25 days. But, if there is a powder that has 70 doses and only requires one dose (which may be a tablespoon of the powder) per day, this will last 70 days. The point is to inform you that even a model with a higher capacity may not be a better deal.

Style

Oh boy, can this be a game changer. At the end of the day, you need to conclude what type of fiber supplement that you want. Generally speaking, they will either be powder-based or tablet-based. Both have their advantages and disadvantages but, to be honest, there is less of a chance that you will have an issue with a capsule than you will with powder. You see, with a capsule, you simply need to swallow it with a glass of water and you are good to go. Yet, with any powders, you will need to dissolve them in water to consume them.

Now, the issues arise with both flavor and texture. With some powders, it will be nearly impossible to create a liquid that does not clump up unless you quickly and vigorously stir the solution. Also, the end result may not even taste very good. Of course, this is solved with flavorless powders that can be dissolved in your favorite beverages. But, capsules are not perfect, either. Some of them can be incredibly difficult to swallow and given you will consume them daily, this could be a potential roadblock.

Materials

A lot of consumers will only be looking for options that are 100 percent natural and those that add no additives or artificial flavors at all. But, some formulas will do just this and while it is not detrimental, keep an eye out if this is something that bothers you. For example, with any additives, they can sometimes trigger allergic reactions or even possibly lead to health issues down the road.

As for artificial flavoring, this is not particularly an issue when it comes to your health. In fact, they typically are not harmful in the slightest. The thing about artificial flavors, though, is their taste can be unsatisfying for some.

Safe for Everyday Use?

Among all the other questions in this section, this is probably the most discussed and frequently asked one. Every consumer around the world seemingly wants to know if a fiber supplement can be taken on a daily basis without any issues. Well, it is important to preface the answer to this by saying that there is no hard evidence to indicate that it is harmful. Of course, if you happen to experience abdominal bloating and excess gas initially, then you may be taken too much too soon. So, what you may want to do is ease your way into, so to speak. Start with maybe one a day and once your body gets accustomed to it, you could then increase it (with this varying from formula to formula).

That being said, it is also important to understand that a supplement is not going to be a replacement for your daily fiber needs. For around every 1000 calories in your diet, you should be getting around 14 grams of fiber. But, you should get this intake from other foods as you also receive the vitamins, minerals, and vast other nutrients.

Frequently Asked Questions

q: Is There Scientific Evidence to Back of Claims?

a:

Before this question is answered, it requires a bit of a backstory for you to understand exactly what is being asked. You see, when you come across some dietary supplements, and this really is referring to any type, there will be claims made. These claims could be associated with the certain health benefits that a certain formula has. As you learned earlier, there are several different types of fibers and subtypes so what about them?

Here is the deal; the claims can be seen as accurate if they were reviewed by the Food and Drug Administration (FDA). In this case, then scientific data is most definitely used to determine if a certain formula will have certain health benefits. To even be approved by the FDA, extensive scientific data from qualified experts is required, in the first place.

q: What Foods and Drinks Can be Used for Mixing?

a:

As you can probably assume, this next question is going to come into play if you do decide to go with a flavorless powder. If it has a flavor, and it is already potent, you may want to avoid mixing it with flavored drinks as the end result could be quite disgusting (but it does depend on your personal taste preference). Yet, with no flavor from the get-go, why not add it to a beverage that you find delectable? The question is, though, what types of beverages come to mind?

Well, your imagination is your only limitation in this case. But, to give you an idea on the drinks that work well, how about cold beverages such as juice? All types of flavors will work including apple, orange, grape, etc. Although, even hot drinks such as coffee could be a good way to go. Then again, you could even add it to foods such as pudding or yogurt. Again, you can get creative.

q: Why Should you Consult your Doctor Beforehand?

a:

Ah, now this is a good one here. A lot of times, manufacturers around the globe who sell and produce these types of supplements will recommend that you consult with your doctor before you consume them. Now, some of you may believe that this is a bit excessive and to be honest, you are accurate. Not everyone will need to do this but if you are fully aware that you have health issues and need to be cautious about what you put inside your body, check with your doctor beforehand.

Going back to what was alluded to earlier, this makes it even more important for you to pay close attention to the full ingredients list of each option out there. Heck, even if you are unsure, it can never hurt to get an expert opinion from a doctor to see if a specific fiber supplement will be optimal for your diet.

q: Will Cooking it Beforehand Affect the Results?

a:

This really plays off one of the previous questions that were alluding to what types of foods and beverages you can use to dissolve your powder in. Let’s say that you are eating dinner and would rather let the powder dissolve in something that you were cooking, could you? The short answer to this question is yes because the consistency and taste of your food is not going to be changed (as long as the powder is flavorless).

In regard to the effectiveness of the powder itself, cooking it is not going to eliminate all the health benefits associated with it. If you decide to go down this path, you will be just fine.

q: How to use them Safely?

a:

Some of you may just automatically assume that you can take as many doses and servings as you want with whatever you want and you will be fine. While the latter is mostly true, even though it is recommended to take large capsules with a full glass of water to prevent any choking, the former is certainly not. As was alluded to in the previous question, most experts will recommend that you build up how many servings you take. Keep in mind, though, you should never take more than the recommended daily dosage (much as you would not with a pharmaceutical drug).

What you may be wondering, though, is what happens if you consume too much fiber in your diet too quickly? There are a variety of side effects that you could endure such as bloating, cramping and excess gas. This is also important as when you are assessing the effectiveness of a specific formula, some buyer’s reviews can be skewed. If they incorrectly consume the supplement, they are pretty much feeding you potentially false information.
