The world of weight loss solutions is vast, encompassing everything from FDA-approved medications to compounded drugs from telehealth companies, unregulated online peptides, and dietary supplements. With the surging popularity of GLP-1 drugs like semaglutide (Wegovy) and tirzepatide (Zepbound), many companies are attempting to capitalize on the trend by offering supplements marketed as "natural" alternatives. This article explores the potential benefits and side effects of GLP-1 supplements, while also addressing concerns surrounding their use.
Understanding GLP-1 Agonists
GLP-1, or glucagon-like peptide-1, is a hormone naturally produced in the body that plays a vital role in regulating blood sugar and appetite. GLP-1 agonists are a class of medications that mimic the effects of this hormone. These drugs stimulate insulin release when blood sugar levels rise, slow down digestion, and increase feelings of fullness, leading to reduced food intake and subsequent weight loss.
How GLP-1 Agonists Work
- Triggering insulin release: GLP-1 agonists prompt the pancreas to release more insulin, which helps lower blood sugar levels.
- Slowing stomach emptying: This leads to a slower release of glucose into the bloodstream, preventing blood sugar spikes.
- Increasing satiety: GLP-1 agonists affect areas of the brain that control hunger and satiety, making you feel fuller for longer.
Prescription GLP-1 Agonists: Medications and Their Uses
Several GLP-1 drugs are FDA-approved for treating type 2 diabetes and obesity. These medications are typically administered as a once-weekly injection. Some of the GLP-1 agonists on the market include semaglutide (Ozempic, Wegovy) and liraglutide (Saxenda, Victoza). Tirzepatide (Mounjaro, Zepbound) is a dual GLP-1/GIP receptor agonist, meaning it mimics both GLP-1 and another hormone called glucose-dependent insulinotropic polypeptide (GIP).
Benefits of Prescription GLP-1 Agonists
- Effective weight loss: GLP-1 agonists have demonstrated significant weight loss results in clinical trials.
- Improved blood sugar control: These medications help manage blood sugar levels in people with type 2 diabetes.
- Additional health benefits: Studies suggest potential benefits for neurological and behavioral health, such as reduced risks of seizures and addiction.
Side Effects of Prescription GLP-1 Agonists
While generally safe when prescribed and monitored by a healthcare provider, GLP-1 agonists can cause side effects, including:
- Gastrointestinal issues: Nausea, vomiting, diarrhea, constipation, bloating, and stomach discomfort are common, especially when starting treatment or increasing the dose.
- "Ozempic face": Sagging and wrinkling of the facial skin due to rapid weight loss.
- Potential risks: Uncommon but serious adverse effects on the pancreas and kidneys have been reported.
GLP-1 Supplements: A Closer Look
Due to the high cost, potential side effects, and the need for injections associated with prescription GLP-1 agonists, many people are turning to supplements marketed as "natural" alternatives. These supplements often contain ingredients like berberine and claim to mimic the effects of GLP-1 agonists.

Concerns About GLP-1 Supplements
- Lack of regulation: The Dietary Supplement Health and Education Act of 1994 (DSHEA) largely bypasses the FDA, meaning supplements do not undergo the same rigorous testing and approval process as prescription drugs.
- Misleading marketing: Supplement companies may exaggerate the benefits of their products, falsely suggesting they can provide the same results as prescription GLP-1 agonists.
- Adulteration: Weight loss supplements have a history of being adulterated with dangerous ingredients, including high levels of stimulants.
- Unproven efficacy: Many supplements lack scientific evidence to support their weight loss claims, and studies on individual ingredients may not translate to the finished product.
- Questionable delivery methods: Patches, for example, are a thorny delivery method, because supplements by the FDA’s definition must be swallowed.
Berberine: A Common Ingredient in GLP-1 Supplements
Berberine is a natural compound found in several plants and is often touted as a weight loss aid. While some studies suggest berberine may help with weight loss, the effects are generally modest. A meta-analysis found that patients taking berberine lost a little over 4 pounds on average. It's important to note that studies on berberine typically involve oral intake, and the effectiveness of transdermal patches containing berberine is unclear.
The Role of Healthcare Professionals
If you are considering GLP-1 agonists or supplements for weight loss or diabetes management, consulting with a healthcare professional is crucial. They can assess your individual needs, medical history, and potential risks and benefits before recommending a treatment plan.
Talking to Your Doctor
- Discuss your weight loss goals and any underlying health conditions.
- Ask about the potential benefits and risks of GLP-1 agonists and supplements.
- Inquire about lifestyle modifications, such as diet and exercise, that can complement medical treatments.
Lifestyle Changes and GLP-1 Therapy
While GLP-1 agonists can be a powerful tool for weight loss and diabetes management, they are not a magic bullet. Lifestyle changes, such as diet and exercise, are essential for maximizing the benefits of GLP-1 therapy and maintaining long-term results.
Dietary Recommendations
- Eat smaller, more frequent meals: This can help reduce nausea and improve blood sugar control.
- Avoid fatty, fried, and spicy foods: These foods can worsen nausea and other gastrointestinal side effects.
- Increase fiber intake: Fiber promotes satiety and helps regulate bowel movements.
- Stay hydrated: Drinking plenty of water can prevent dehydration and constipation.
Exercise Recommendations
- Engage in regular physical activity: Exercise helps burn calories, build muscle mass, and improve overall health.
- Combine cardio and strength training: Cardio exercises, such as walking, running, and swimming, help burn calories, while strength training helps build muscle mass.
The Future of GLP-1 Research
Researchers continue to explore the potential benefits and risks of GLP-1 agonists and related therapies. Ongoing studies are investigating the use of GLP-1 agonists for various conditions, including:
- Type 1 diabetes
- Alzheimer's disease
- Addiction
