If you’re looking to lose weight, you might be wondering if weight loss pills are safe. Some diet supplements have harmful ingredients and may even cause side effects.

If you’re serious about losing weight, it’s important to find a safe and effective diet supplement. Look for one that is made in a cGMP-certified facility and uses third-party testing.

Stimulants

Weight loss pills typically contain stimulants that curb your appetite and make you feel fuller. These drugs are safe and can be prescribed by your doctor for short-term use (up to 12 weeks). They include phentermine and topiramate. They are often used for people who need to lose weight before they can undergo bariatric surgery. But they can also be used long-term to minimize weight regain after surgery. These medications are usually combined with other supplements.

Chitosan

Often sold as a weight loss supplement, chitosan is an indigestible polysaccharide that is derived from the exoskeleton of crustaceans. It is also a component of food packaging and wound dressings.

The chitosan found in these supplements is a manufactured form of the polysaccharide that is purported to promote weight loss by binding to some dietary fat in the digestive tract, preventing its absorption. It may also help lower cholesterol levels.

Some people who use these supplements experience side effects including flatulence, bloating, mild nausea and constipation. If you have any of these symptoms, talk to your doctor about whether you should stop taking the chitosan or switch to another supplement.

In addition, chitosan may interfere with the body’s ability to absorb fat-soluble vitamins A, D, E and K. In some people, this may lead to a vitamin deficiency or nutrient imbalance. It may also affect your blood sugar level. If you are diabetic, be sure to check with your doctor before taking any supplemental choline or chitosan.

As a weight-loss supplement, chitosan may be safe and effective when taken in doses of three to four grams per day for up to six months. However, more research is needed to determine the best dose and to understand the potential risks and benefits.

Studies have shown that chitosan helps people lose weight and lower their total cholesterol and LDL “bad” cholesterol levels. It may also be effective for lowering blood pressure and for reducing inflammation in the body.

It has also been shown to decrease triglycerides and increase HDL levels in healthy people. These results have been reported in a number of well-designed studies.

It is safe to take a daily dose of chitosan supplements if you are healthy and not taking any medications. It is important to read the product label carefully and follow the directions. It is also a good idea to discuss any supplemental products with your physician before starting them, as they can provide more personalized recommendations and suggest dosages that are right for you.
