Best 10 health benefits of Chitosan 

Crab, shrimps, squids and crayfish, all these sea animals not only offer a variety of seafood but also offer the hard shells with great benefits. The shell provides a substance named Chitosan which is an indigestible fiber and supports the body’s gastrointestinal system offering other health benefits as well. It is one of the supplements with least side effects and toxicity. Following are the topmost benefits:

1. Helps manage weight

The nature of Chitosan is a contributory factor in losing weight. This is why many nutritionists guide the patients to add such natural food items in their diet to ensure healthy living with proper weight adjustment.

2. Improves bowel function

As it is a fiber its major roles revolve around GIT health and support. It helps in relieving constipation and keeping your bowel habits healthy. Also, it prevents indigestion and helps in diseases like the Crohn’s disease (an inflammatory condition of the gastrointestinal tract).

3. Treats skin conditions

Acne is one of the commonest skin problems affecting people with oily skin. Taking Chitosan supplement helps in preventing rash and itching sensation that come along with the skin disease.

4. Helps in anemia

Patients with anemia often feel weak, tired, numbness, have shortness of breath on exertion, and might often present with smooth red tongue. During anemia, the body absorption of nutrients like Chitosan also decreases. By taking it externally or by adding it to your diet helps in improving the body’s health status.

5. Lowers down cholesterol

There are good and bad, both types of cholesterol. To stay healthy and prevent coronary artery diseases the body needs to get rid of the low-density or the bad cholesterol. Chitosan is one of the nutritional supplements that help in lowering the raised cholesterol levels in the body.

6. Detoxifies liver

The liver is involved in both synthetic and detoxifying functions. The harmful chemicals and toxins building up in the body are eliminated with the help of the liver. A healthy liver is necessary to keep the body free from toxins and Chitosan helps in doing so.

7. Insulin-effect promoter

The supplements are capable of maintaining the body’s glucose levels by promoting insulin hormone effects. The studies have shown that diabetic patients can gain benefit with its regular use.

8. Protects against infection

Chitosan provides the body support and fitness to fight against the invading body agents like bacteria, fungi, and viruses. It keeps the body strong and makes the user’s immune system strong.

9. Prevent tumor formation

The studies carried out in Japan on the benefits of Chitosan are consistent with the findings that it helps in protecting the body cells and prevents irregular activities like tumor growth.

10. Lowers high blood pressure

High blood pressure is often difficult to maintain and people who take anti-hypertensive medicines daily are quite fed up with their routine. To assist them to keep the blood pressure levels down, Chitosan supplements can be added to their regular diet. The results of using this supplement are quite promising!
