  • Digestion: IBS, constipation, diarrhea
  • Weight
  • Health: cardiovascular, blood sugar, hormones

Feature Ingredients

  • Sunfiber®: a soluble fibre that is derived from partially hydrolyzed guar gum, a highly soluble, prebiotic form of fibre derived from the endosperm of the cluster bean. Guar gum is fermented more slowly in the intestinal tract than some other prebiotic fibres, making it easily tolerated

Regulates bowel function & manages symptoms of IBS

  • Supports digestion and gastrointestinal health
  • Promotes healthy blood sugars and cardiovascular health
  • One of the most well-tolerated fibers available; low FODMAP compliant
  • Clinically studied and patented fibre

Fiber is an essential part of a healthy diet. However, the average daily intake of fiber is only about half of the recommended intake of 30-35 g per day. Soluble fiber is not digestible by enzymes in the gastrointestinal system, but is instead fermented by healthy bacteria in the gut. Soluble fiber enhances gastrointestinal health, function and regularity, and increases satiety. It also supports healthy blood sugar balance and cardiovascular health. A low intake of dietary fiber has been associated with an increased risk of cardiovascular disease.

Supplemental forms of fiber have been found to be more effective than fiber from the diet. AOR’s SoluFiber contains partially hydrolyzed guar gum, a highly soluble, prebiotic form of fiber derived from the endosperm of the cluster bean. Guar gum is fermented more slowly in the intestinal tract than some other prebiotic fibers, making it easily tolerated. Hydrolyzation is a controlled natural process that breaks guar gum down into smaller units, greatly decreasing its viscosity and allowing the particles to dissolve more readily, while maintaining the original fiber content. It is a patented highly soluble form of fiber that has been used in clinical trials, studied in children, and found to be one of the most palatable and well-tolerated soluble fibers that does not alter the taste and texture of food or drink.

SoluFibre contains Sunfiber®, a soluble fibre derived from guar bean gum. Sunfiber® improves intestinal/bowel regularity and provides gentle relief of constipation in the general population as well as in people with irritable bowel syndrome (IBS). Helps relieve minor gastrointestinal symptoms associated with IBS.

AOR Advantage

AOR’s SoluFibre contains partially hydrolyzed guar gum, a highly soluble, easy to take, digestion resistant form of fibre that imparts no flavor or texture change to the foods it’s added to. It has been studied in clinical trials, it has been found to have the greatest range of beneficial results and health applications, and it has been found to be the most tolerable form of fibre for children due to its lack of flavour and texture-changing characteristics.

Research Based Facts

Gastrointestinal Health

Several studies have shown that soluble fibers are effective in reducing diarrhea and decreasing recovery times following intestinal surgery.

Guar Gum Benefits Irritable Bowel Syndrome

The results of using partially hydrolyzed guar gum (PHGG) in irritable bowel syndrome patients were compared, at 10 g and 5 g per day taken over a period of 12 weeks. Gastrointestinal symptoms along with quality of life, and psychological symptoms were noted at baseline, at months 1 and 3 of treatment, and at month 6 follow-up observation.

In both treatment groups, quality of life and symptoms improved significantly after the first month of administration, until follow-up in comparison to the baseline. Over the short term, the guar gum was effective for improving somatic (gastrointestinal symptoms) and psychological (quality of life and psychological distress) symptoms.

However, the improvement was significantly reduced at follow-up compared to the end of treatment. Improvements in bowel functions tended to decrease after the end of the treatment period, additional studies should evaluate the benefits of PHGG at a maintenance dosage.

Treatment for Functional Constipation

The results of using a partially hydrolyzed guar gum was investigated in the treatment of functional constipation among patients in hospital. Following a blind, randomized, controlled-trial, 64 adults were divided into two groups: one group adhered to a daily high-fiber diet (approximately 30 g), and the other a comparable diet with the addition of 10 g of  partially hydrolyzed guar gum, over a 15 day period. Dietary fiber improved functional constipation by 78.0%. Partially hydrolyzed  guar gum did not cause any additional effect in frequency of defication, fecal consistence, necessity of laxative drug use, although bowel complaints were reduced. The study results indicate that dietary fiber can be useful for functional constipation treatment, although further studies are recommended.

Guar Gum is a Well Tolerated Fiber

High-fiber diet sources are commonly used in IBS, although there can be several problems managing the condition. Partially hydrolyzed guar gum (PHGG) has exhibited beneficial effects in human studies and animal studies. In one such study, the effects of PHGG in IBS patients were compared to a wheat bran dietary fiber intake. Bowel habits, abdominal pain and patient views of the treatment were evaluated in a total of 188 IBS patients, all of whom were adults.

Patients were divided into classifications of having either diarrhea-predominant, constipation-predominant, or changeable bowel habits and were then assigned to random groups receiving 30 g of wheat or 5 g of PHGG fiber per day. Patients were more likely to switch from PHGG from wheat bran than vice versa. Both fibers were effective at improving pain and bowel habits.

However, significantly more patients in the guar gum group reported a greater subjective improvement than those in the wheat fiber group. In conclusion, improvements in core IBS symptoms (abdominal pain and bowel habits) were observed with both bran and PHGG, but the latter was better tolerated and preferred by patients, revealing a higher probability of success than bran and a lower probability of patients abandoning the prescribed regimen, suggesting that it can increase the benefits deriving from fiber intake in IBS, making it a valid option to consider for high-fiber diet supplementation.

Metabolic Health

Prospective studies have suggested that soluble fiber intake is inversely associated with the risk of coronary heart disease. Other studies have suggested inverse associations between dietary fiber and cardiovascular disease risk factors such as blood pressure, waist-hip ratio, fasting insulin level, triglyceride levels and fibrinogen levels. Fiber’s effects on insulin benefit the cardiovascular system, since insulin is thought to play a role in blood pressure regulation, blood clotting and blocking the formation of arterial plaque. Several clinical trials have found that dietary fibers lower cholesterol and low-density lipoprotein levels. One analysis found that soluble fiber has a favorable effect on blood lipids, in which the increase of each gram of dietary fiber lowered the concentration of low-density lipoprotein cholesterol in the blood by about 0.052 mmol/L. Population studies have found that a lower intake of fiber is associated with higher blood pressure. An increase in fiber consumption generally results in a blood pressure balancing effect.
