Millions of people worldwide are continuously looking for methods to lose excess weight, and weight loss has always been a popular topic. A healthy lifestyle still starts with diet and exercise, but sometimes it seems like progress is taking a long time.
At that point, a lot of people use supplements, more especially the best over-the-counter weight loss pills, to help them lose weight. These pills are more widely accessible than prescription medications because they can be purchased without a doctor’s prescription.
Dietary supplements or FDA-approved drugs that you can purchase over-the-counter (OTC) without a prescription from pharmacies, grocery stores, or internet retailers are known as OTC weight loss pills.
OTC pills, in contrast to weight loss prescription drugs like Phentermine or Contrave, are either FDA-approved drugs at lower dosages, like Alli (Orlistat 60mg), or they are regulated as dietary supplements, meaning they don’t need FDA approval before going on sale.
What Are Over-the-Counter Pills for Losing Weight?
Dietary supplements known as over-the-counter weight loss pills make the claim that they can help people lose weight by altering their appetite, metabolism, or absorption of fat. OTC pills are promoted as “safe” for everyday use, in contrast to prescription medications like Phentermine that need medical supervision.
How OTC Weight Loss Pills Usually Work
Over-the-counter pills often work in three main ways:
Blocking Fat Absorption
Some pills, like Alli (orlistat 60 mg), stop the body from absorbing about 25% of dietary fat, letting it pass through instead. Mayo Clinic+1
Boosting Fat Burning / Metabolism
Ingredients like caffeine and green tea extract can raise your daily calorie-burning rate, even when resting.
Suppressing Appetite
Natural ingredients such as fiber (like glucomannan) or Garcinia cambogia make you feel full, so you eat less.
