In recent years, many people have turned to natural dietary supplements (aka "hunger pills") to help control their appetite and manage weight. While some supplements have little to no scientific evidence supporting their claims, others have demonstrated effectiveness in suppressing appetite. In this post, we'll look at some of the best selling appetite control pills, their ingredients and the scientific research that may or may not support the claims.

Scientific Research
Acetyl L-Carnitine HCL
Acetyl L-Carnitine HCL is a compound that is naturally produced in the body and also found in some foods. It is often used as a dietary supplement and has been studied for its potential health benefits, including weight and appetite control, especially in adults with overweight/obesity.
In a 2020 meta-analysis published on Clinical Nutrition ESPEN, the official publication of the European Society for Clinical Nutrition and Metabolism (ESPEN), researchers analyzed 37 randomized controlled trials with a total of 2292 participants. They found that l-carnitine supplementation significantly reduced body weight, body mass index (BMI), and fat mass. They also found a non-linear dose-response association between l-carnitine supplementation and body weight reduction, suggesting that ingestion of 2000 mg l-carnitine per day provides the maximum effect in adults [1] Trusted Website Official publication of the European Society for Clinical Nutrition and Metabolism (ESPEN).

Green Tea Extract (EGCG)
As discussed earlier, the main active ingredient of green tea extract is EGCG (Epigallocatechin Gallate), which is a type of catechin. EGCG has strong antioxidant and anti-inflammatory properties, which may protect cells from damage, suppress the activity of pro-inflammatory chemicals, and reduce the risk of chronic diseases such as heart disease, cancer, and diabetes; EGCG may also promote weight loss, especially when taken alongside caffeine, and may improve neurological cell function and prevent degenerative brain diseases.
5-HTP
As discussed earlier, 5-HTP is a natural amino acid precursor that is used by the body to produce serotonin, a neurotransmitter that regulates mood, appetite, and sleep.
Caffeine Anhydrous
As discussed earlier, Caffeine Anhydrous is a concentrated, powdered form of caffeine that is commonly used to improve alertness and mental focus.
Cayenne Pepper Extract
As discussed earlier, Cayenne Pepper Extract is a concentrated liquid or powder made from chili pepper, commonly used in cooking and for its potential health benefits, particularly could be beneficial for weight loss and weight maintenance.
Salicin (White Willow) Bark
White willow bark has been used for centuries in China and Europe to treat pain, inflammation, and fever. The bark contains a chemical called salicin, which is similar to aspirin and is believed to be responsible for the pain-relieving and anti-inflammatory effects of the herb.

(Image: Frontier Co-op Store at Amazon)
Willow bark also appears to relieve headaches and back pain, and can be useful for osteoarthritis. However, people who are allergic or sensitive to salicylates (such as aspirin), or who have certain medical conditions, should avoid taking willow bark.
L-Tyrosine
L-Tyrosine is a nonessential amino acid produced by the body from phenylalanine. It is important for the production of several neurotransmitters that help nerve cells communicate, influencing mood. Some studies suggest that tyrosine supplements may improve memory and performance under psychological stress and may help increase alertness after sleep deprivation. However, further research is needed to confirm these findings.
Tyrosine is found in soy products, chicken, fish, peanuts, and dairy products, and is also available as a dietary supplement in capsule or tablet form. If you have a medical condition, take medication, or have migraine headaches or hyperthyroidism, you should talk to your doctor before taking tyrosine supplements.
L-Theanine
Theanine is an amino acid found in tea and some mushrooms that is sometimes used to improve mental function, reduce anxiety and stress, and enhance cognitive function.
While there is some evidence to suggest that taking L-theanine by mouth might help healthy people stay focused, there is not enough reliable information to support many of the other potential uses for theanine.
Theanine is generally considered safe when used short-term. However, there is not enough evidence to know if it is safe for long-term use, and it may cause mild side effects like headaches or sleepiness. Theanine may also interact with some medications, including those for high blood pressure and sedatives, so caution should be used when taking theanine in conjunction with these medications.
Synephrine HCl
Synephrine is a compound found in bitter orange, a small tree that bears fruit sometimes used in small amounts in food as a flavorant and often used in pre-workout and weight-loss supplements. Synephrine is similar to ephedra, a substance that was banned by the FDA due to its serious effects on the heart.

(Image: A. Barra at Wikimedia)
There are some concerns about the safety of synephrine, as adverse events such as chest pain, increased heart rate, and stroke have been reported in association with dietary supplements containing synephrine. While the data to support these concerns are not strong, U.S. DoD's Operation Supplement Safety program advised service members to err on the side of caution when considering whether to use supplements containing synephrine, and warned that synephrine might register on an initial military urine screening test for amphetamines, although it will not cause a positive result on confirmation drug tests[18].
Potential Side Effects
The product contains caffeine and synephrine HCl, which are stimulants and may cause side effects such as jitteriness, anxiety, and difficulty sleeping. Additionally, cayenne pepper may affect people with a sensitivity to nightshades. People with caffeine sensitivity or autoimmune conditions should consult with a healthcare professional before taking this supplement.
Medication for Appetite & Weight Control
Prescription appetite suppressants can be effective when combined with a healthy diet and exercise, leading to a weight loss of 3% to 9% of the starting weight within 12 months. Some people may benefit from using appetite suppressants as a jumpstart to weight loss and to learn to recognize cues that signal when they are full.
It is important to note that using appetite suppressants should not be the sole method of weight loss and should be combined with lifestyle changes for best results. Also, appetite suppressants can have side effects and are not recommended for everyone, including those with certain medical conditions or who are pregnant or breastfeeding.
The Food and Drug Administration (FDA) has approved these prescription appetite suppressants:
- Diethylpropion (Tenuate dospan®).
- Liraglutide (Saxenda®).
- Naltrexone-bupropion (Contrave®).
- Phendimetrazine (Prelu-2®).
- Phentermine (Pro-Fast®).
- Phentermine/topiramate (Qsymia®).
If your ultimate goal is to lose weight and keep fit, Alli® is a widely used over-the-counter weight loss aid developed by GlaxoSmithKline. It is the only FDA-approved non-prescription weight loss product available in the United States. Its active ingredient, orlistat, has been clinically proven to help individuals lose weight effectively and safely.
Alli works by blocking the absorption of dietary fats in the body, which in turn reduces the number of calories consumed. The main component, orlistat, inhibits the action of lipase enzymes in the gastrointestinal tract, preventing the breakdown and absorption of fat from food. As a result, the unabsorbed fat is excreted through the digestive system, leading to weight loss [19] Trusted Website PubMed is a data base from US National Institutes of Health. It's a trusted source of health and medical information. Open the link → .
The FDA approved Alli for over-the-counter use in 2007. Customer reviews of Alli have been generally positive, with many users experiencing significant weight loss over time. Alongside a reduced-calorie, low-fat diet and regular exercise, Alli has helped countless people reach their weight loss goals. However, it is essential to note that results may vary, and some users may experience side effects, such as gastrointestinal discomfort.
