NOW Foods Glucomannan Pure Powder (8 oz / 227 g) – 100% Pure Konjac Root Fiber
NOW Foods Glucomannan 100% Pure Powder is an all-natural, water-soluble dietary fiber harvested directly from the root of the traditional Asian konjac plant (Amorphophallus konjac). When mixed with water before a meal, this pure root fiber naturally expands in your stomach to create a gentle, soothing gel. This simple physical action helps you feel satisfied and full after eating, supports smooth daily bowel regularity, and helps maintain healthy cholesterol levels that are already within the normal range.

Buyer Guide & Fiber Form Comparison
Why Pure Konjac Root Powder Matters
Not all dietary fibers act the same way inside your digestive tract. Everyday fiber supplements often use insoluble wheat bran or low-viscosity psyllium husk, requiring giant scoops of gritty powder that can cause harsh bloating or sudden gas. Konjac root glucomannan is remarkable because it holds the highest water-holding capacity of any natural dietary fiber known to science – holding up to 50 times its own weight in water. By choosing 100% pure loose powder, you get pure active fiber without swallowing multiple large capsules, while avoiding all synthetic binders, flow agents, or fillers.
Is This Formula Right for You?
- Ideal For Shoppers Who:
- ✓Want a 100% pure, single-ingredient fiber supplement with zero additives, zero sweeteners, and zero excipients.
- ✓Prefer stirring a versatile, unflavored powder into water or smoothies rather than swallowing multiple pills.
- ✓Seek natural mealtime fullness to manage appetite and dependable daily bowel regularity without harsh laxatives.
- Consider Another Option If:
- ✘You have a history of swallowing difficulties or narrowing of the esophagus.
- ✘You cannot comfortably drink a full 8 to 10-ounce glass of liquid immediately after mixing the powder.
- ✘You need pre-portioned capsules for convenience while traveling away from home.
Risk-Free Assurance: Every purchase at VitaNet®, LLC is backed by our unconditional 100% money-back guarantee – even on opened containers, with return shipping covered – so you can test the digestive benefits of pure glucomannan completely risk-free.
How Glucomannan Works Inside Your Body
To understand how glucomannan works, think of it as a microscopic, all-natural super-sponge [1]. Chemically, glucomannan is a long chain of plant sugars (D-mannose and D-glucose) linked tightly together by beta-1,4 molecular bonds. Because the human stomach lacks the digestive enzymes needed to break these unique bonds apart, the fiber travels through your stomach and upper digestive tract completely intact [2]. Its journey supports your wellness through three distinct biological steps:
1. In the Stomach: Natural Fullness Signals
As soon as the powder meets the water (H2O) you drink with it, it rapidly absorbs the liquid and swells into a soft, smooth gel. This gel takes up physical room in your stomach, gently pressing against the stomach lining. That gentle stretching sends instant nerve signals directly to your brain saying, "I am comfortably full." This process slows down how fast food empties from your stomach into your intestines, helping keep you satisfied long after you finish eating [1, 2].
2. In the Small Intestine: Trapping Cholesterol & Moderating Sugars
As the thick glucomannan gel moves into your small intestine, it forms a slippery barrier along the intestinal wall. This natural matrix traps some of the cholesterol, dietary fats, and digestive bile acids from your meal [1, 3]. Because bile acids are made from cholesterol, carrying them out through your stool forces your liver to pull circulating cholesterol right out of your bloodstream to make fresh bile. This helps maintain healthy cholesterol levels that are already in the normal range [1]. At the same time, it slows carbohydrate breakdown, preventing rapid post-meal sugar spikes [3].
3. In the Colon: Prebiotic Fuel for Regularity
Once glucomannan reaches the large intestine, it acts as a premium prebiotic food for your friendly gut bacteria [4]. Good microbes ferment the fiber into nourishing short-chain fatty acids (such as butyrate and acetate) that keep your colon cells strong and healthy. Meanwhile, the water-rich gel adds soft, comfortable bulk to your stool, allowing your digestive muscles to move waste along easily and reliably [4].

Dosing, Timing & Synergy Protocol
Optimal Timing & Liquid Pairing
Mix 1/2 level teaspoon (approx. 2 grams) into at least 8 full ounces (a large glass) of water or juice. Stir vigorously and drink immediately. Take this mixture 30 to 45 minutes before a meal. Drinking it right after mixing is essential because the pure powder begins thickening into a gel within minutes of touching liquid.
Crucial Safety Warning: Always take this product with plenty of liquid. Without drinking enough water, the powder can swell inside your throat or esophagus, causing blockage or choking. Never consume dry powder, and avoid use if you have ever had narrowing of the esophagus or difficulty swallowing.Daily Dosing Strategy
Start by taking 1/2 level teaspoon once daily before your largest meal (such as dinner) during your first week. This allows your digestive system to adapt smoothly. After the first week, you can take 1/2 teaspoon before two separate meals daily. Spreading your intake across the day maintains steady digestive fullness without overloading your stomach.
Smart Synergies & The 2-Hour Spacing Rule
Because glucomannan forms a thick gel that traps nutrients and slows digestion, it can block the absorption of daily medications and vitamins if taken at the same time. Always follow this simple rule: take all prescription medications, fat-soluble vitamins (such as A, D, E, and K), and mineral supplements at least 2 hours before or 2 hours after drinking your glucomannan serving.
Timeline of Expectations
- ✓Week 1 (Initial Acclimation): You will notice that you feel satisfied faster during meals and stay full longer between them. Bathroom visits become smoother as your stool absorbs hydration. Be sure to drink plenty of water throughout the day.
- ✓Weeks 3–4 (Digestive Balance): Regular, comfortable bowel movements become your daily routine. Unwanted afternoon snacking urges decrease as post-meal digestion stays balanced.
- ✓Months 2–3+ (Long-Term Maintenance): Continuous daily soluble fiber intake provides sustained support for healthy cholesterol levels and normal blood sugar balance when paired with your active lifestyle and nutritious diet.
Physical Traits, Sensory Details & Clean Excipients
Delivery Format & Practical Handling
NOW Foods Glucomannan Pure Powder comes in an 8-ounce (227-gram) tub containing ultra-fine, free-flowing root powder. It easily measures out with a standard kitchen measuring spoon. The tub contains a small freshness packet to protect the powder from moisture (do not eat the packet). Because this product is sold by weight rather than volume, slight settling during shipping is completely normal.
Natural Aroma, Taste & Color Notes
The powder has an off-white to soft cream natural hue. It carries a very mild, neutral botanical scent and virtually no flavor when stirred into water or cold fruit juice. Because NOW Foods uses pure konjac root without bleaching chemicals, synthetic dyes, or artificial flavors, subtle color variations between harvest lots are completely natural.
Other Ingredients Demystified: The Power of None
The "Other Ingredients" listing for this pure formula reads: None. Translating this into real consumer value:
- ✓Zero Fillers or Flow Agents: No magnesium stearate, silicon dioxide, or microcrystalline cellulose.
- ✓Zero Sugars or Artificial Sweeteners: No maltodextrin, dextrose, sucralose, or sugar alcohols that could trigger gas or raise blood sugars.
- ✓Zero Animal Gelatin: 100% pure botanical root powder suitable for strict vegan and vegetarian lifestyles.
Storage & Powder Longevity
Store the container tightly closed in a cool, dry pantry or cupboard after opening. Keep the tub away from moist environments like steamy bathroom counters or kitchen stovetops, as pure konjac powder naturally attracts ambient moisture and can clump if exposed to steam.
NOW Brand Lab Purity: Advanced Contaminant Screening & Testing Standards
Because konjac is a root vegetable that grows deep underground, it naturally absorbs water and minerals from the soil. In discount, big box store brands, cheap root powders are frequently harvested from unmonitored industrial soils that contain high levels of toxic heavy metals, soil pesticides, and chemical runoff. Unsuspecting shoppers often buy these discount store brands without realizing they are loaded with hidden contaminants or diluted with cheap starches.
NOW Foods protects you from low-grade ingredients by operating one of the largest, most advanced private testing complexes in the entire natural supplement industry. Across their private, ISO/IEC 17025 accredited laboratories in Bloomingdale, Illinois and Sparks, Nevada, NOW chemists run over 19,000 analytical tests every single month to guarantee absolute safety, purity, and potency:
- ✓Ultra-Trace Heavy Metal Screening (ICP-MS): Using Inductively Coupled Plasma Mass Spectrometry, NOW checks every lot of konjac root for lead, arsenic, cadmium, and mercury down to parts-per-billion (ppb) limits. Ingredients must pass safety rules that strictly beat California Proposition 65 standards – the toughest environmental standards in the nation.
- ✓Botanical Identity & Viscosity Verification (HPLC & HPTLC): High-Performance Liquid Chromatography chemically fingerprints incoming raw materials to prove it is authentic Amorphophallus konjac with genuine high molecular weight, making sure it has not been diluted with cheap corn, rice, or potato starches.
- ✓500+ Pesticide & Solvent Chemical Scan (GC-MS/MS & LC-MS/MS): Advanced dual-mass spectrometry screens raw materials against over 500 chemical pesticides, agricultural weed killers, and industrial extraction chemicals.
- ✓Microbial Pathogen Clearance: Automated DNA and plate assays verify that every batch is 100% free from dangerous bacteria including Salmonella, E. coli, and Staphylococcus aureus, alongside strict limits on yeast and mold.
- ✓Eco-Friendly Packaging: Encased in an environmentally responsible bottle made from 100% post-consumer recycled (PCR) resin, keeping plastic out of landfills.

Frequently Asked Questions
Why do I need to drink this immediately after stirring it into water?
Glucomannan begins absorbing liquid and swelling into a thick gel within seconds of contact with moisture. If you let it sit on your counter, it turns into a thick pudding that is very difficult to drink. Stirring it briskly into at least 8 to 10 ounces of water and drinking it right away ensures that it washes smoothly into your stomach before expanding.
