Leanbean is on the top of our list because, other than glucomannan, it contains a powerful combination of green coffee extract, turmeric, and Garcinia Cambogia, and with these ingredients, it has proven to be one of the most potent and effective fat burners for my clients.

Leanbean is also the safest choice for women. It’s low in stimulants (like caffeine), which can cause jitters and nausea. It uses alternatives like Vitamin B12 to give you an energy boost (especially when you’re on diet mode) [1].

Leanbean’s customers love that it’s both an appetite suppressant and a mood enhancer (a feature lacking in other supplements on this list).

  • Quick facts: Glucomannan: 3000mg, Choline: 82.5mg, Garcinia Cambogia: 100mg
Pros
  • A well-balanced blend of appetite-suppressing and fat-metabolizing ingredients
  • Free from soy, gluten, and GMOs
  • Low stimulant content makes it ideal for consumption before bedtime
  • Offers a money-back guarantee
Cons
  • Each serving (two pills) should be taken three times a day for efficacy, which some might consider a high dosage

NOW has been one of the leaders in the natural products industry since 1968, and they joined the glucomannan game in 2011 with NOW Foods Glucomannan Powder.

NOW’s glucomannan powder adds high-quality fiber to your diet, aiding your weight loss by keeping you full. As a powdered glucomannan, you can add it to any of your favorite foods and protein shakes. It also doubles as a thickener for your soups and gravies.

In addition to supporting our bowel movement, NOW Glucomannan Pure Powder definitely aided weight loss and healthy cholesterol levels for me and most of my clients, which makes long-term weight management a bit easier.

Recommended serving is 1/2 teaspoon, and it should be taken with eight oz. of water before every meal, twice a day.

Nature’s Way has always been a front-runner in producing quality health products. And they’ve come through yet again with a premium glucomannan supplement.

At 1,995 mg per serving, Nature's Way claims it will keep your stomach filled, barring hunger for three to five hours. Some of my clients reported they felt like they’d just had a meal.

What sets Nature’s Way Glucomannan apart from some other glucomannan supplements is that users have reported reaching their desired results with smaller doses. So, you should be getting value for your money.

This product comes from a company called Nutricost and is flavorless with no aftertaste. So, you can add it to all your foods without sacrificing taste. Since it’s in the powdered form, it’s also a good substitute for flour to be used as a carb-free thickener.

I really liked the fact that it's flavorless because I added it to my shakes and soups, and it only affected the texture, which I didn’t mind at all.

  • Quick facts : Non-GMO Glucomannan Powder
Pros
  • No flavors or aftertaste
  • Good flour substitute for thickening sauces, gravies, and soups
  • Small serving size, so one bottle will last a long time

This powder produced by BulkSupplements is based on the Konjac Root Extract. Glucomannan comes from this root vegetable whose soluble fiber reaches your lower intestines (where it breaks down) faster than other fibers.

It’s great for supporting your digestive health and cardiovascular system while aiding weight loss (provided you exercise and follow a calorie-restricted diet) [2].

My clients reported it helped them with intermittent fasting because it limited their hunger and increased energy.

Over the past 45 years, Puritan’s Pride has played a major role in the health and fitness industry, and they’re claiming their glucomannan capsule is made with ingredients of the highest quality.

In addition to glucomannan, this unique formula combines another traditional herbal ingredient that was proven to support weight loss and overall wellness, and that’s white kidney bean [3].

It’s friendly to all diets because it’s free of the ingredients like artificial colors, flavors, sweeteners, and preservatives.

While it did affect our satiety positively, our team concluded it might be better for improving the sense of well-being rather than effective weight loss.

  • Quick facts:Konjac Root: 1000mg, White Kidney Bean: 1000mg
Pros
  • Made with the high-quality ingredients
  • Contains both glucomannan and white kidney bean for overall wellness

Buyer’s Guide and Considerations

man holding a mini shopping cart

Before you purchase any glucomannan product, consider the following.

Fitness Goals

You should choose the supplement based on your health goals. If your primary aim is satiety and digestion, you might need to choose a supplement that’s pure glucomannan.

But if your goal is to lose weight more effectively and quickly, you might want to choose a supplement like Leanbean that combines multiple ingredients; each one included to help with effective fat burning.

You should keep in mind that glucomannan, with its properties and mechanisms, is still the main active ingredient for weight loss here as well.

With its low energy density and bulking properties, glucomannan seems to promote weight loss by displacing the energy of other nutrients and producing satiety and satiation as it absorbs water and expands in the gastrointestinal tract. - Joyce Keithley, Professor at College of Nursing, Rush University, Chicago

Supplement Form

Two primary forms this supplement comes in are capsules and powders. Now, you should choose powders if your want to have absolute control over the precise amount you take in.

This might be preferable for people who like to fine-tune their intake and experiment with doses. Also, this form is easy to mix with beverages and stews, and it even might be used as a thickener in the kitchen.

Capsules, on the other hand, are much more convenient, especially on the go. They are also tasteless, so you don’t need to worry about mixing them with anything. They also offer the benefit of standardized intake without the hassle of measuring your doses every time.

Glucomannan Dosage

Studies did not determine the exact safe or effective dosage for health purposes, but the number that’s is usually mentioned in research papers is 1 - 5 grams of glucomannan, one to three times a day [4] [5].

So, based on your individual needs and preferences, you should choose supplements that offer higher or lower dose per capsule, but my advice is to go with the golden middle of what is used in scientific studies, and that’s 3g.

FAQs

How Much Glucomannan Should I Take To Lose Weight?

You should take 1 to 5 grams of glucomannan three times a day with water to lose weight. Be sure to take it before meals; otherwise, it won't help with weight loss.

How Long Can You Take Glucomannan?

You can take glucomannan supplements daily for up to four months without the risk of side effects.

What Is the Standardized Glucomannan Supplement Dosage?

There is no standardized dosage for glucomannan supplements because the FDA does not regulate it.

Are There Any Side Effects of Glucomannan Supplements?

There are no known side effects to taking glucomannan. However, uncoated glucomannan pills or powder can be a potential choking hazard if taken with insufficient water.

Can I Take Glucomannan before Bed?

Some people recommend taking glucomannan before bed, while others advise against it. The timing of your intake should depend on your reaction to it and the specific instructions on the label.

Our #1 Glucomannan Supplement Recommendation

After a few months of testing and gathering feedback from our clients and online users, our team at TotalShape concluded that Leanbean is probably the best glucomannan supplement currently on the market. You can check results from our clients using it in our Leanbean review.

It combines multiple high-quality ingredients with no harmful stimulants to curb your appetite and ramp up the fat utilization for energy while giving your body the nutrients it requires for overall health.

I’ve been using it for a long time myself for my cutting phases, and it never failed to deliver on its promised effectiveness with no stomach upset or any side effects common with these supplements.

Ordered yours today to find out if it’ll make as much of a difference for you as it did for my clients and me.
