Below is general information about the safety of the known ingredients contained in the product Glucomannan & Chicory Root Powder. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when consumed in amounts commonly found in food. Chicory and chicory extract have Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when used orally in medicinal amounts, short-term. Chicory root extract has been used with apparent safety at doses of 600 mg three times daily for one month (93647). Chicory seed has been used with apparent safety as a hot water infusion of 4.5 grams twice daily for 12 weeks (102350). There is insufficient reliable information available about the safety of chicory when used orally, long-term, or when used topically.
PREGNANCY: POSSIBLY UNSAFE
when used orally in excessive amounts.
Chicory may induce menstruation or miscarriage (19).
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally as food (11358,11359). Glucomannan powder or flour is often used to enrich noodles in traditional Japanese foods.
POSSIBLY SAFE ...when used orally with at least 250 mL (8 ounces) of water or other fluid. Glucomannan has been safely used in studies lasting up to 4 months (178,179,181,182,11046,11294,11357,11294,54240,57775)(57781,57783,57784,92004,92008,92009,92010,92011,106410). In the European Union, the maximum permitted level in foods is 10 grams/kg (106411).
POSSIBLY UNSAFE ...when used orally without any liquid, especially when in tablet form. There have been reports of choking and esophageal or gastrointestinal obstruction when glucomannan products are taken dry. A safety alert for this has been issued by Health Canada (11293,57785,106410).
CHILDREN: POSSIBLY SAFE
when used orally and appropriately with at least 250 mL (8 ounces) of water or other fluid.
Glucomannan has been safely used in children for up to 4 months (179,180,11295,57775,57779,92005,92006,97935).
CHILDREN: LIKELY UNSAFE
when used orally without any liquid, especially when in tablet form.
There have been reports of esophageal and gastrointestinal obstruction when glucomannan products are taken dry (11293,57785,106410).

Theoretically, glucomannan may decrease absorption of drugs taken orally.
Details
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 (11360). 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 (112703). To avoid changes in absorption, take glucomannan 30-60 minutes after taking oral drugs.

Below is general information about the adverse effects of the known ingredients contained in the product Glucomannan & Chicory Root Powder. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, chicory seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, belching, bloating, and flatulence.
Dermatologic ...Occupational exposure to chicory may cause skin rash, contact dermatitis, or generalized pruritus (41609,93649). The sesquiterpene lactones of the plant may be the allergens (41609). Chicory may cause an allergic reaction in individuals sensitive to the Asterceae/Compositae family (25416). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.
Gastrointestinal ...Orally, fructo-oligosaccharides, such as those extracted from chicory, can cause flatulence, belching, abdominal pains, intestinal sounds and bloating, which occur commonly, but are mild at doses of 10 grams daily (740,745,750,8509,93716).
Immunologic ...Occupational exposure to chicory may cause allergic reactions. Dyspnea and anaphylaxis have also been reported in a patient with regular occupational exposure to chicory. This patient also experienced contact dermatitis and generalized pruritus (93649).
Pulmonary/Respiratory ...Occupational exposure to chicory may cause asthma and rhinoconjunctivitis (41617,93648). Dyspnea and anaphylaxis have also been reported in a patient with regular occupational exposure to chicory. This patient also experienced contact dermatitis and generalized pruritus (93649).
General
...Orally, glucomannan is generally well tolerated when taken with plenty of water or other liquid.
Most Common Adverse Effects:
Orally: Abdominal pain, bloating, constipation, diarrhea, flatulence, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Choking and esophageal or gastrointestinal obstruction, especially when taken as a dry powder or in tablet form.
Gastrointestinal ...Orally, glucomannan can cause gastrointestinal disturbances, including abdominal pain, bloating, constipation, diarrhea, flatulence, nausea, and vomiting, especially when taken in doses of more than 3 grams daily (57781,57784,92004,92010,92011,97935,106411). Esophageal and gastrointestinal obstructions have been reported when dry glucomannan-containing products are taken with insufficient fluid (11293,57785,106410).
Hepatic ...Acute cholestatic hepatitis occurred in a 31-year-old male after taking glucomannan orally for 45 days (57777). He was also taking other supplements, including garlic and chitosan, so it is unclear whether the hepatitis was due to glucomannan, other supplements, or the combination.
Pulmonary/Respiratory ...Cases of occupational respiratory disorders, including respiratory sensitization and bronchial asthma, have been reported in workers exposed to glucomannan (57789,57810).
