Product Description

Glucomannan, also known as Konjac root is a water soluble dietary fibre which can absorb 200 times its body weight, and acts as an expanding gel when combined with water.  As a result it’s proven to be a popular weight loss aid.

Glucomannan Fibre complex provides the prized benefits of Konjac root in a synergistic formula which includes: bitter orange peel, raspberry ketones, caffeine anhydrous, green tea, L-Tyrosine, African mango, capsicum, guarana, Siberian ginseng and peperine), with vitamin B6, choline, zinc, chromium picolinate and iodine all packed in a practical capsule format.

How does Glucomannan Complex work?

Our unique Glucomannan Complex formula features a potent combination of fat burners, lets look into the ingredients in more detail:

Glucomannan (Konjac root)

Glucomannan is naturally high in fibre, features almost no calories and can absorb up to 50 times its weight.

Studies have found that Glucomannan contributes to weight loss in the context of an energy-restricted diet. This beneficial effect is obtained with a daily intake of 3g of glucomannan in three doses of 1g each, together with 1-2 glasses of water, before meals[1].

Choline

Lipids are fat like substances, and choline is a water soluble nutrient which contributes to normal lipid metabolism.

Bitter Orange Peel

Bitter orange and its peel contain a unique substance called p-synephrine.

Capsicum (chili pepper)

Capsicum contains capsaicin, which is responsible for the hot and spicy sensation associated with chili peppers. Early studies show Capsaicin may help increase metabolism when combined with exercise[2].

Raspberry Ketones

Raspberry ketones are natural phenolic compounds which are responsible for the aroma of red raspberries. These have a molecular structure similar to capsaicin[3].

Iodine

Iodine contributes to normal energy-yielding metabolism, the normal production of thyroid hormones and normal thyroid function.

Chromium picolinate

Chromium contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels[4].

Caffeine anhydrous

Take advantage of the thermogenic properties of caffeine with pure caffeine extract[5].

Zinc

Zinc contributes to normal acid-base metabolism, normal carbohydrate metabolism, normal macronutrient metabolism and normal metabolism of fatty acids[6].

Green tea

Green tea is rich in polyphenols, particularly EGCG, which may be linked to anti-oxidant and thermogenic functions[7].

L-Tyrosine

An amino acid and a precursor of several important neurotransmitters, including l-dopa, dopamine, norepinephrine, and epinephrine, L-tyrosine is also a precursor to the thyroid hormone, thyroxine (also known as T4)[8].

African Mango (Irvingia gabonensis)

Native to West Africa, the African Mango seed is a natural source of soluble fibre[9].

Guarana

Guarana is one of the richest sources of caffeine (contains more caffeine than coffee beans) has has historically been used by the Amazonian tribes for its energy boosting properties.

Vitamin B6

Vitamin B6 contributes to the regulation of hormonal activity, normal cysteine synthesis, normal energy-yielding metabolism, normal homocysteine metabolism, normal protein and glycogen metabolism and the reduction of tiredness and fatigue[10].

Siberian Ginseng

Siberian ginseng contains compounds called eleutherosides, and is often called an “adaptogen.”[11]

Piperine

Piperine may help raise the level at which nutrients are absorbed by inhibiting key enzymes responsible for metabolising nutrients[12].

Glucomannan studies

Effect of glucomannan on obese patients: a clinical study

An eight-week double-blind trial was conducted to test purified glucomannan fiber as a food supplement in 20 obese subjects. Glucomannan fiber (from konjac root) or placebo was given in 1-g doses (two 500 mg capsules) with 8 oz water, 1 h prior to each of three meals per d. Subjects were instructed not to change their eating or exercise patterns. Results showed a significant mean weight loss (5.5 lbs) using glucomannan over an eight-week period. Serum cholesterol and low-density lipoprotein cholesterol were significantly reduced (21.7 and 15.0 mg/dl respectively) in the glucomannan treated group. No adverse reactions to glucomannan were reported.

http://www.ncbi.nlm.nih.gov/pubmed/6096282

Konjac-mannan (glucomannan) improves glycemia and other associated risk factors for coronary heart disease in type 2 diabetes. A randomized controlled metabolic trial.

A total of 11 hyperlipidemic and hypertensive type 2 diabetic patients treated conventionally by a low-fat diet and drug therapy participated. After an 8-week baseline, all were randomly assigned to take either KJM fiber-enriched test biscuits (0.7 g/412 kJ [100 kcal] of glucomannan) or matched placebo wheat bran fiber biscuits during two 3-week treatment phases separated by a 2-week washout period. The diet in either case was metabolically controlled and conformed to National Cholesterol Education Program Step 2 guidelines, while medications were maintained constant.

Total and LDL (bad) cholesterol were significantly reduced by 19 ± 2.7% and 29 ± 3.4% during glucomannan treatment compared to 6.3 ± 3.4% and 6.6 ± 5.0% on the control treatment.

An improvement in blood sugar control was observed on the glucomannan 5.6 ± 1.5% (P 0.003), compared with 0.39 ± 1.3% for the control group.

Glucomannan fiber added to conventional treatment may ameliorate glycemic control, blood lipid profile, and sBP in high-risk diabetic individuals, possibly improving the effectiveness of conventional treatment in type 2 diabetes.

Evaluation of the action of glucomannan on metabolic parameters and on the sensation of satiation in overweight and obese patients

The authors studied the behavior of body weight, blood glucose, total serum cholesterol, and hunger and satiety sensation in 30 patients treated for 60 days with a 1.200 kcal (5040 kj) diet plus either placebo or glucomannane. All the variables considered show that the low-calorie diet plus glucomannane is more effective than the low-calorie diet alone.

http://www.ncbi.nlm.nih.gov/pubmed/7796558

Chronic use of glucomannan in the dietary treatment of severe obesity

Two groups of 25 severely obese patients underwent 3 months of hypocaloric diet therapy either alone or associated with a glucomannan-based fibrous diet supplement (approx. 4 g/die in 3 doses). The comparative analysis of the results obtained in both groups showed that the diet + glucomannan group had a more significant weight loss in relation to the fatty mass alone, an overall improvement in lipid status and carbohydrate tolerance, and a greater adherence to the diet in the absence of any relevant side effects. Due to the marked ability to satiate patients and the positive metabolic effects, glucomannan diet supplements have been found to be particularly efficacious and well tolerated even in the long-term treatment of severe obesity.

Caffeine studies

Effects of caffeine on energy metabolism, heart rate, and methylxanthine metabolism in lean and obese women.

The magnitude of coffee-induced thermogenesis and the influence of coffee ingestion on substrate oxidation were investigated in 10 lean and 10 obese women, over two 24-h periods in a respiratory chamber.

On one occasion the subjects consumed caffeinated coffee and on the other occasion, decaffeinated coffee. The magnitude of thermogenesis was smaller in obese (4.9 +/- 2.0%) than in lean subjects (7.6 +/- 1.3%). The thermogeneic response to caffeine was prolonged during the night in lean women only. The coffee-induced stimulation of energy expenditure was mediated by a concomitant increase in lipid and carbohydrate oxidation

http://www.ncbi.nlm.nih.gov/pubmed/7485480

Comparison of changes in energy expenditure and body temperatures after caffeine consumption.

Twelve young healthy male volunteers participated in a randomized blind study in which they consumed 150 ml decaffeinated coffee with or without 200 mg added caffeine.

After caffeine consumption the metabolic rate increased immediately with 0.2 +/- 0.2 kJ/min (p < 0.05) and remained elevated for the 3 h during which measurements were taken. Mean total caffeine-induced thermogenesis was 0.30 +/- 0.20 kJ/min, which means a mean increase in the metabolic rate of 7 +/- 4% during 3 h.

http://www.ncbi.nlm.nih.gov/pubmed/7486839

Normal caffeine consumption: influence on thermogenesis and daily energy expenditure in lean and postobese human volunteers.

Single-dose oral administration of 100 mg caffeine increased the resting metabolic rate of both lean and postobese human volunteers by 3-4% (p less than 0.02) over 150 min and improved the defective diet-induced thermogenesis observed in the postobese subjects.

Green tea studies

Effect of green tea catechins with or without caffeine on anthropometric measures: a systematic review and meta-analysis

Fifteen studies, with 1243 patients in total found on average that green tea catechins with caffeine was associated with statistically significant reductions in BMI, body weight, and waist circumference.

    A bit of a chore to take 4 capsules a day, but they seem to work. My appetite is no longer ravenous at lunch and I was able to tighten my belt by a notch within 6 weeks.

  2. Rated 5 out of 5

    Carla

    these diet pills are really effective, and I feel much more in control of my cravings and hunger. i just wish it could come in a smaller packet as they are not easily taken to work in a handbag!
