There are several weight loss supplements in the market today, all promising the same thing in little to no time. It is, therefore, important to do your research before making any purchase at all. Before we begin to tell you how much you stand to gain from trying it out, you need to know what exactly it is. Keep reading because we’re about to tell you all you need to know about this supplement.

What Is Chitosan?


Chitosan is a form of natural fat-soluble sugar (Chitin) obtained from the hard outer skeleton (Exoskeleton) of crustaceans like Shellfish, crab, lobster shrimp. This fat-soluble sugar is incorporated in the different forms of medicines, and it is useful for a variety of health challenges. Chitosan pills are frequently promoted as one of the best natural means to lose weight by preventing fat absorption. However, there isn’t enough evidence to back up this theory.

According to a report published in the Cochrane Database of Systematic Reviews in 2008, 15 clinical trials were tested for Chitosan’s effects. This trial includes a total of 1,219 adults who were either overweight or obese. Compared with those on blind placebo-controlled, the researchers found out that participants treated with Chitosan lost significantly more weight and experienced beneficial changes in their cholesterol levels and blood pressure. Unfortunately, the author specifically noted that the clinical trials compared with blind placebo-controlled patients were of low quality. However, an in-depth analysis via subsequent high-quality trials suggests that Chitosan may have a minimal and insignificant effect on weight.

Aside from the review published on the Cochrane Database of Systematic Reviews, many other types of research are based on the study on Chitosan effects that suggests that Chitosan may have altered the cholesterol and blood pressure levels when in use. However, its effect on weight loss is significantly minimal.

The Chitosan element can also be referred to as one of the following names;

  • Ascorbate de Chitosane 
  • Chitosane Déacétylé
  • Chitosan Ascorbate
  • Deacetylated Chitosan
  • Chitosane Mono-Carboxyméthylé
  • Enzymatic Polychitosamine Hydrolisat
  • N,O-Sulfated Chitosan
  • HEP-30
  • Mono-Carboxymethylated Chitosan
  • Hydrolisat Enzymatique de Polychitosamine
  • N-Carboxybutyl Chitosan
  • O-Sulfated N-Acetylchitosan
  • N-Carboxybutyl Chitosane
  • Quitosano
  • Trimethyl Chitosan Chloride
  • Sulfated N-Carboxymethylchitosan
  • Sulfated O-Carboxymethylchitosan

How Does Chitosan Work?

Chitosan works by blocking the absorption of dietary fat. This excellent dietary supplement combines the fat in your body and prevents it from depositing & accumulating. Thus, preventing weight gain and making your body appear slimmer. The fat and cholesterol are subsequently excreted together with your feces whenever you decide to use the toilet.

What sets Chitosan supplements apart from some of the best weight loss pills is its proposed action mode. Unlike some of the best pills and supplements that require you to exercise and eat right, taking Chitosan works differently.

The Chitosan supplement is available and sold in solid, powder, and liquid form. Chitosan tablets and capsules are dry and solid, while the liquid is yellowish. According to the FDA, Chitosan 500mg tablets can be administered alone or with other supplements like Chromium. However, Chitosan’s liquid variation may be considered better because it is easier to pass out. Unlike the tablet form, which creates large clumps of gel-like fat in the digestive system, the liquid Chitosan breaks them down into tiny pieces. Hence, they digest quickly and are easier to pass.

Side Effects Of Using Chitosan

Like every other drug or supplement, there are certain effects of Chitosan you should always consider. Taking Chitosan may have some side effects despite helping with high cholesterol levels and total body weight. According to research, taking Chitosan may cause some adverse effects in your system, depending on how you react.

Some of these effects are;

  • Constipation
  • Upset stomach
  • Reduced absorption of some essential nutrients like calcium and vitamins A, D, E, and K.
  • Hypersensitive allergic reactions in people with shellfish allergies

Due to a lack of research, there is little known about Chitosan’s effects on pregnant women and nursing mothers. If you fall within this category, it’s best to avoid using it. Also, it is hard to ascertain how safe Chitosan is for regular or long-term.

Safety Guidelines/Concerns

Although the effects of Chitosan are undeniable, you should consider a few safety concerns:

  • It is difficult for pregnant women to tell how safe Chitosan is for your baby, so it is best to speak to a doctor or stay away from this supplement altogether.
  • Shellfish allergy: As you already know, the Chitosan element is derived from the exoskeleton of Shellfish. If you are allergic to Shellfish, you might be allergic to Chitosan. However, experts have stated that you can only be allergic to the meat, and not the shell.
  • Interaction With Different Medication: One of the vital medications you should worry about is Warfarin (Coumadin). Warfarin is a blood thinner, and taking chitosan supplements in combination with it can increase the chances of bruising or bleeding. Hence, if you take any medication with Warfarin present in the composition, talk to your doctor for proper directives.

What Is The Use Of Chitosan?

The use of Chitosan isn’t limited to weight loss and reduction of total cholesterol only. This potent supplement is also valuable for many reasons;

  • Weight loss: The very first and widespread use of Chitosan is for reducing body weight. Although there are minimal/conflicting results about how effective Chitosan is for weight loss, it has been promoted for a long time. Nevertheless, according to some other studies, there may be a minimal effect on weight loss combined with a diet. This may be true, as studies have shown that taking Chitosan for 1-6 months without a strict diet will help you lose about 0.5 kg (about 1.1 pounds). Chitosan may also be more effective when combined with exercises.
  • Gum Disease (Periodontitis): Periodontitis is a painful swelling of the gums due to inflammation caused by bacteria. Applying Chitosan ascorbate directly to your swollen gums seems to help eliminate harmful bacteria and reduce the swelling.
  • Kidney Failure: According to reviews on the Cochrane database, Chitosan helps alleviate symptoms such as anemia, reduced physical strength, and sleep in individuals suffering from kidney failure who are on long-term hemodialysis.
  • Improving Your Immune System: Chitosan can improve your immune system in two ways: humoral and cellular immunity. These processes entail the formation of antibodies and activating lymphocytes T and B, respectively, which is excellent for fighting against bacteria and foreign bodies. It’s also great for activating Natural killer (NK) cells, which fight against cancer cells. Thus, Chitosan supplements are considered ten times more effective than any other treatment options for cancer.
  • Crohn’s disease: Crohn’s disease is an intestinal disorder that early studies suggest can be managed with Chitosan. This research concludes that a combination of Chitosan and ascorbic acid is taken orally will help individuals who have Crohn’s disease.
  • High cholesterol: There is no concluding evidence that shows the use of Chitosan helps reduce cholesterol. While some research showed that Chitosan supplements do not significantly reduce total cholesterol, the other research shows the opposite. However, there are certain products with a combination of essential elements that help reduce high cholesterol levels. These elements are Chitosan, Chromium, Garcinia, Ascorbic acid, Guar Meal, and other micronutrients. Any product with a combination of these elements helps in reducing body weight and cholesterol levels.
  • Wound Healing: According to early research, applying the liquid form of Chitosan to skin grafts help nerves grow faster, thus catalyzing the process of wound healing. The fantastic supplement is also useful for recovery after plastic surgery. In this case, applying N-carboxybutyl chitosan directly to the area prevents scar formation and helps hasten the recovery process.

Chitosan can also be used in other sectors for different purposes; For instance, Silica-chitosan elements are used for polyglycolate and silk stitches, which is excellent for fixing wounds. It improves the recovery time and prevents the formation of dangerous microorganisms, making it less susceptible to infections. It also acts as an excellent emulsifier for making bread dough and keeps drinks such as apple juice clear.

Does Chitosan Really Work?

Yes, Chitosan really works. It is effective for weight loss by binding fats into gel-like chunks, making it easier to excrete. Combining your intake with a low carb diet and cardio exercises like swimming, brisk walking, etc. improve your chances of getting better results. Chitosan will work with a dosage of 2500mg daily taken between your three main meals for at least 12 weeks. Taking it less or more than 12 weeks will hinder its effect against burning down fat.

Is Chitosan Good For Kidneys?

Chitosan is excellent and safe for the kidneys. As a matter of fact, Chitosan can be used to help improve the symptoms associated with kidney failure, especially patients on long term hemodialysis.

How Much Chitosan Should I take Daily?

The advised dose of Chitosan you can take daily is around 2500mg. This should be taken before your three main meals. Also, be sure to take this tablet at least 15 minutes before each meal with two glasses of water. If you’re looking to lose weight, try combining this supplement with a low-carb diet and some cardio exercises. Also, ensure you stay hydrated by drinking plenty of water, as this will make it easier to excrete the bonded gel-like fats through your stool.

Like the Leanbean review, taking the right dosage of Chitosan supplements are very crucial, regardless of its intending function. Whether you need them for weight loss or balancing your cholesterol levels, you need the right prescription to see results.

As for the treatment, you will need to be on your Chitosan supplement for at least twelve weeks before seeing any result. However, it is dangerous to prolong its usage for an extended period (fifteen weeks). Unfortunately, prolonging the duration for the above 15 weeks will interfere with your desired result.

For Periodontal Disease: If you suffer from Periodontal disease, try applying Chitosan powder directly on your gums or try a Chitosan chewing gum periodically. This will drastically alleviate your gum inflammation.

Can Diabetics Take Chitosan?

According to a study designed to ascertain if Chitosan has any effect on diabetic rats, the results showed that Chitosan has the potential for alleviating type-1 diabetic hyperglycemia. This result is achieved through the decrease in liver gluconeogenesis and an increase in skeletal muscle glucose uptake. However, you should speak with your doctor first before taking any supplement or drug.

That way, your doctor can educate you on the potential risk or not of taking the medication.


In conclusion, the Chitosan supplement offers various health benefits such as weight loss, improving your immune system, enhancing wound healing, etc., and is available in different forms. Trying out the Chitosan pills may be beneficial to you, regardless of what you hope to gain. All you need to keep in mind is follow through with instructions and seek your doctor’s advice if you have any underlying health issues.

Also, remember that Chitosan can react differently to several types of medications. It is essential to stay away from this supplement if you take blood thinners, as it could make your situation worse. Plus, always hydrate, because it helps with passing out the clumps of fat as feces.
