HelloPharmacist Scorecard of Glucomannan from Konjac Root by Wonder Laboratories
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains two active ingredients. Glucomannan is a soluble fiber extracted from konjac root that absorbs water and bulks up in your digestive tract.
Chromium is a mineral that plays a role in how your body uses and stores carbohydrates and fat. The remaining ingredients—gelatin, vegetable cellulose, and vegetable magnesium stearate—are inactive components that form the capsule and help hold it together.
Does it work?
Moderate evidence
Glucomannan is rated possibly effective for constipation, diabetes, and high cholesterol (hyperlipidemia). Chromium is rated likely effective for chromium deficiency and possibly effective for diabetes.
However, chromium is rated possibly ineffective for prediabetes, schizophrenia, and high blood pressure. The evidence supporting these uses comes from clinical research, though for some conditions the data isn't yet strong enough to be certain.
How safe is it?
Well-documented data
Both ingredients are generally well tolerated when taken properly with plenty of water. With glucomannan, the main caution is that it must be swallowed with liquid—taking it dry or with too little water can rarely cause choking or blockage of the esophagus or intestines.
Common mild side effects from either ingredient include abdominal pain, bloating, gas, diarrhea, nausea, and vomiting, especially at higher doses of glucomannan (above 3 grams daily). Chromium is usually well tolerated at typical supplement doses, though long-term or high doses may carry risks for some people.
There isn't enough reliable safety data to know whether glucomannan is safe during pregnancy or breastfeeding, so talk with your doctor before using it if you're pregnant or nursing. For chromium, small amounts from food or a prenatal vitamin are generally considered acceptable during pregnancy, but extra supplement doses should be avoided unless your doctor recommends them.
Similarly, there is limited safety data on higher chromium doses while breastfeeding.
Meds to double-check
Moderate interaction found
If you take insulin, antidiabetes drugs (such as metformin or sulfonylureas), or levothyroxine, check with your doctor or pharmacist before starting this product—chromium may lower your blood sugar or reduce how much thyroid medication your body absorbs. NSAIDs and aspirin may increase how much chromium your body retains.
Glucomannan can reduce absorption of oral medications in general, so space this product and your other drugs apart by at least 2 hours if possible and confirm with your pharmacist.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you have constipation, diabetes, or high cholesterol, and you take no prescription medications for blood sugar or thyroid function, this product may be worth discussing with your doctor or pharmacist. If you take insulin, antidiabetes drugs, levothyroxine, NSAIDs, or aspirin, check your exact medications with your healthcare provider before starting, since this product interacts with all of them.
Always take glucomannan capsules with plenty of water to avoid choking or blockage.

Glucomannan from Konjac Root by Wonder Laboratories Drug Interactions
HelloPharmacist Interaction Report
Wonder Laboratories' Glucomannan from Konjac Root contains two active ingredients—glucomannan and chromium—and both have documented interactions with medications.
The most serious is chromium's Moderate-severity interaction with antidiabetes drugs and insulin, which may increase the risk of low blood sugar (hypoglycemia) by adding to their glucose-lowering effects.
Read the full breakdown — every affected drug type, severity by severity
Glucomann can decrease how well your body absorbs oral medications in general, due to its bulk and thickness in the digestive tract. Chromium interacts with levothyroxine (thyroid medication), potentially reducing how much your body absorbs—a clinical study found a 17% drop in levothyroxine levels when taken together.
Chromium also carries Minor-severity interactions with nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin, which may increase how much chromium your body retains.
Although we hold no interaction data for the inactive ingredients (gelatin, vegetable cellulose, vegetable magnesium stearate), you should check your specific medications with the search tool on this page before starting. Altogether, these interactions span 2,057 individual medications.

For each ingredient in Glucomannan from Konjac Root with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Glucomannan
Oral Drugs
Theoretically, glucomannan may decrease absorption of drugs taken orally.
Due to its viscosity and bulking effects, there is concern that glucomannan can decrease the absorption of oral drugs. A small clinical study in healthy volunteers shows that taking glyburide 2.5 mg plus glucomannan 3.9 grams with breakfast reduces plasma levels of glyburide when compared with breakfast and glyburide alone. In addition, animal research demonstrates this effect on amoxicillin, but shows increased absorption of metronidazole. This mouse model also demonstrates that metronidazole elimination is prolonged, but amoxicillin elimination is enhanced by 38%; glucomannan may also affect the distribution of some drugs. To avoid changes in absorption, take glucomannan 30-60 minutes after taking oral drugs.
Chromium
Antidiabetes Drugs
Theoretically, chromium may have additive effects with antidiabetic agents and increase the risk of hypoglycemia.
Some research shows that taking chromium might lower blood glucose levels, especially in patients with poorly controlled type 2 diabetes.
Insulin
Theoretically, concomitant use of chromium and insulin might increase the risk of hypoglycemia.
In clinical research, chromium has been shown to increase insulin sensitivity,
Levothyroxine (Synthroid, Others)
Chromium might bind levothyroxine in the intestinal tract and decrease levothyroxine absorption.
Clinical research in healthy volunteers shows that taking chromium picolinate 1000 mcg with levothyroxine 1 mg decreases serum levels of levothyroxine by 17% when compared to taking levothyroxine alone. Advise patients to take levothyroxine at least 30 minutes before or 3-4 hours after taking chromium.
Aspirin
Theoretically, aspirin might increase chromium absorption.
Animal research suggests that aspirin may increase chromium absorption and chromium levels in the blood.
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)
NSAIDs might increase chromium levels in the body.
Drugs that are prostaglandin inhibitors, such as NSAIDs, seem to increase chromium absorption and retention.
