What is Amsa Fast?

The United States of America is ranked 9th for obesity, with a 2016 report revealing that close to 75% of the total population is overweight. To help solve this problem, people should use more supplements. Amsa Fast (Orlistat) is specifically designed as a weight-loss supplement to block fat absorption in the body. Its main ingredient, Orlistat, acts to help control obesity, preventing the regaining of the lost weight after a diet program by blocking around 30% of the fat ingested from being absorbed.

Because Orlistat is an FDA-approved weight-loss drug, there’s research that shows just how effective it can be – for some users.

  • International Journal of Clinical Pharmacology and Therapeutics – So, how much Amsa Fast do you need to lose weight? According to research, when Orlistat is delivered in tablet form, the best results came from a 144mg dose – much higher than any other counter variety of this drug suggests and more than the typical prescription.
  • Pharmacology Research – And, in patients who take Orlistat, the more weight they lose, the better their cholesterol numbers.
  • Endocrine – There’s even 2020 research that shows taking Orlistat with cinnamon extract may improve results even more.

What is Orlistat?

Orlistat is the main ingredient in Amsa Fast and helps control obesity. It is available over the counter in many countries under Alli, but its clinical name is Xenical, according to the U.S. Library of Medicine.

Its primary purpose is to prevent fats from being absorbed and stored by the human body. This is due to its effect as a lipase inhibitor, which reduces the overall calories consumed by users.

What are Lipase Inhibitors?

Lipase is an enzyme secreted into the gastrointestinal tract by the pancreas, according to StatPearls. These enzymes help metabolize ingested fats, sending them on to the intestines to be absorbed. Lipase inhibitors act by binding with these enzymes, thus reducing their effectiveness, according to PubChem.

This, then, reduces the gastrointestinal absorption of fats, which helps with weight loss. Optimally, a person’s caloric intake should consist of around 40% fats when taking Amsa Fast. It will then block the absorption of excess fats while still letting you get a healthy amount.

Weight Loss

Amsa Fast and Weight Loss

By reducing the amount of fat being processed and absorbed by the body, Amsa Fast (Orlistat) helps promote weight loss, per research published in Drugs. Blocking the incoming fat forces the body to consume previously-stored fats. This means that it is crucial to eat a diet low in sugars to assist the conversions of stored fats into energy.

The manufacturers claim that combining Amsa Fast with a low-calorie diet, it can help fight high cholesterol and maintain healthy blood pressure. Thus, with just a few modifications to your overall diet, the prescription diet pill can help promote significant weight loss and healthier living.

How to Take Amsa Fast

Amsa Fast (Orlistat) works a bit differently than most weight loss supplements, focusing on blocking fat absorption rather than boosting energy levels or metabolism. It should be taken one hour before or after eating to work best and can be skipped if you have missed any meals.

What Is the Dosage?

In a standard box of Amsa Fast (Orlistat) 120 mg, there are 21 capsules, which is the standard seven-day course. Doctors recommend that three pills be taken daily, before or after eating.

  • Lulu (Verified Purchase)

    As per my experience this pill is for those people that don’t like to or don’t do enough exercise and don’t not minimize the grease intake or diet properly. That is one reason why there is that secondary effect of the bowel movements. Also this can occur when taking to many pills. This is a supplement to eliminate the grease in the food intake such as burgers, pizza, pasta, etc.

  • lourdes kachmar
