What is Konjac?
Konjac, also known as glucomannan, is a type of herb that grows in some parts of Asia. It is popular for its starchy corm, a tuber-looking part of the stem that grows underground. The corm is utilized to make a rich source of soluble dietary fiber. Konjac is utilized as a gelatin substitute, which is further used to thicken or add texture to foods.

These plants are also utilized for the manufacturing of a number of medicines, consisting of supplements for dietary fiber, capsules, gels, and others.

Six Health Benefits of Konjac
Konjac has various potential health benefits. Many of these benefits can be related to its substantial content of glucomannan, the soluble dietary fiber that is naturally present in the konjac plant.
Following are some of the potential health benefits:
1. Diabetes Management
According to research, consumption of a mix of glucomannan and American ginseng can result in a moderate improvement in the management of type 2 diabetes. Additionally, a study of 2015 found that consumption of glucomannan could prevent the diabetes patients from increasing their sugar levels. This is because consuming glucomannan results in a heavy stomach and makes stomach full for longer period of time.
2. Weight Management
Glucomannan made from konjac may be beneficial for people who are trying to lose weight. A study found that the soluble dietary fiber supplement helped overweight people to reduce their body weight. The participants in the study took the supplement as part of a balanced, calorie-controlled diet. Konjac is used as a laxative, which helps in the elimination of toxic materials from the intestine, which facilitates weight loss. However, one study of 2014 found that there was no benefit of using glucomannan versus placebo for weight loss. Also, side effects of the fiber supplement included abdominal discomfort, diarrhea, and constipation.
Glucomannan can help a person feel full for longer by reducing the rate at which the digestive system empties. Researchers also compared the effects of the glucomannan supplement with those of a guar gum supplement. They discovered that the glucomannan supplement slightly increased weight loss, whereas the guar gum supplement did not.
3. Cholesterol Control
High cholesterol can increases a person’s risk of heart disease and stroke. Doctors also recommend water-soluble fiber to help in keeping healthy cholesterol levels and provide support in weight management.
A 2019 study performed on rats with diabetes found that administering konjac glucomannan substantially decreased total cholesterol levels along with low-density lipoprotein, which is known as bad cholesterol. Moreover, a study of 2017 revealed that the dosage of glucomannan was able to improve cholesterol levels. Researchers found that consumption of three grams per day is considered to be beneficial for health.
Taking a glucomannan supplement is also considered to help regulate a proper bowel movement and prevent constipation. A review from 2017 explained that taking glucomannan improved the frequency of bowel movements in children with constipation. A study from 2018 also found that glucomannan supplementation can improve constipation symptoms during pregnancy.
5. Healthy Skin
The glucomannan content is also considered to help improve the skin. For instance, a study found that glucomannan can offer benefits as a topical therapy for acne, as well as improve overall skin health.
6. Wound Healing
Along with supporting skin health, glucomannan is believed to help heal the body wounds faster. One experiment found that glucomannan supplements might amplify wound healing by supporting the immune system. However, more research is required to conclude that glucomannan has the same effect in humans.
