A few years ago, \u201cGLP-1\u201d was not a household term. Today, GLP-1 medications are widely used across the United States. Roughly 1 in 8 adults have used a prescription glucagon-like peptide-1 agonist (GLP-1) to treat obesity, Type 2 diabetes, or another health condition, according to a KFF survey.\u00a0<\/span><\/p>\n

GLP-1 receptor agonist medications<\/span><\/a> require a prescription and can be expensive. As a result, some people are exploring natural supplementation options such as GLP-1 supplements.<\/span><\/p>\n

What is a GLP-1 supplement?<\/span><\/h2>\n

A GLP-1 supplement is a product intended to support glucagon-like peptide-1, a hormone your gut naturally produces. GLP-1 helps regulate your appetite, digestion, and blood sugar.\u00a0<\/span><\/p>\n

When people talk about GLP-1 supplements, they may mean one of two things. The first is an over-the-counter supplement marketed to support the body\u2019s natural GLP-1 production. These products may contain ingredients such as berberine, probiotics, soluble fiber, curcumin, or ginseng. However, they\u2019re not the same as<\/span> prescription GLP-1 receptor agonists<\/span><\/a>. Manufacturers are not required to prove that they work the same way prescription medications do.\u00a0<\/span><\/p>\n

Prescription GLP-1 medications, which are approved by the FDA, are different because they are GLP-1 receptor agonists. That means they are designed to bind to and activate GLP-1 receptors directly. They mimic the body\u2019s natural GLP-1 hormone. This causes slow stomach emptying, appetite regulation, increased feelings of fullness, and insulin release support after eating. Because they act directly on GLP-1 receptors, their effects are much more targeted, measurable, and clinically studied than those of supplements marketed for GLP-1 support.\u00a0\u00a0<\/span><\/p>\n

The second category includes vitamins and minerals recommended for people taking an FDA-approved GLP-1 prescription. Because these medications can reduce appetite, some people may eat less than usual, which can increase the risk of nutritional gaps. Supplements such as vitamin D, vitamin B12, calcium, and magnesium ensure they are getting the micronutrients they need to remain healthy.\u00a0<\/span><\/p>\n

\u201cOne of the biggest nutritional risks on GLP-1 is unplanned muscle loss because most people are not eating enough,\u201d explains registered dietitian <\/span>Ashley Kitchens, RDN<\/span><\/a>, owner of Plant Centered Nutrition in Durham, North Carolina.\u00a0<\/span><\/p>\n

Do GLP-1 supplements work?<\/span><\/h2>\n

Over-the-counter GLP-1 supplements have not been shown to produce meaningful weight loss or replicate the effects of prescription GLP-1 receptor agonist medications in clinical trials. Supplements may only modestly influence the body\u2019s GLP-1 production, while FDA-approved prescription medications directly activate GLP-1 receptors for a stronger, more predictable effect.<\/span><\/p>\n

The recent surge in interest in GLP-1 medications has led to a growing market for supplements. However, experts caution against assuming GLP-1 supplements work the way prescription medications do.\u00a0<\/span><\/p>\n

Researchers and public health experts have raised concerns that the branding creates unrealistic expectations. In an <\/span>\u00a0article from Harvard T.H. Chan School of Public Health<\/span><\/a>, experts warn that consumers may reasonably assume that products marketed around “GLP-1” work the same as prescription medications, even though there is no evidence to support that.<\/span><\/p>\n

\u201cAt this point, there aren’t any OTC supplements that provide the same benefits as the injectable GLP-1s,\u201d says <\/span>Erika Gray, Pharm.D<\/span><\/a>., founder and chief medical officer at ToolBox Genomics. \u201cBecause the prescription GLP-1s actually bind to and activate GLP-1 receptors, it has been difficult to replicate these effects orally with a plant extract, herbal compound, or probiotic.\u201d However, several oral GLP-1 pills are available, including Ozempic, Wegovy and Foundayo.<\/span><\/p>\n

Some ingredients used in GLP-1 supplements may support digestion, blood sugar regulation, or overall metabolic health. However, that does not mean the supplement itself has been proven to reduce appetite, improve blood sugar, or support weight loss in the same way as prescription GLP-1 medications.\u00a0<\/span><\/p>\n

Another important difference is regulation. The FDA does not evaluate over-the-counter dietary supplements for safety or efficacy before they are sold. This means manufacturers do not have to prove their products work before putting them on the market. Prescription medications such as <\/span>Mounjaro<\/span><\/a>, <\/span>Zepbound<\/span><\/a>, <\/span>Wegovy<\/span><\/a>, and <\/span>Ozempic<\/span><\/a>, on the other hand, require FDA approval for prescriptions.<\/span><\/p>\n

What supplements may naturally increase GLP-1?<\/span><\/h2>\n

Some supplements may help support the body\u2019s natural GLP-1 production, including soluble fiber, probiotics, and certain plant-based compounds. However, the evidence is still limited. Many studies have been performed on rats, in lab settings, or on very small sample sizes of humans. These findings do not prove that supplements work like prescription GLP-1 medications. However, some experts say certain ingredients may still support overall metabolic health.\u00a0<\/span><\/p>\n

\u201cBerberine, fiber, or both could be a good place for someone to start to balance their metabolic health if they do not need something as strong as the injectable GLP-1s,\u201d says Dr. Gray.<\/span><\/p>\n

Soluble fiber\u00a0<\/span><\/h3>\n

Soluble fiber, including inulin and psyllium husk, has some human evidence for supporting the body\u2019s natural GLP-1 response. Soluble fiber absorbs water in the digestive tract, which slows nutrient absorption and may stimulate the cells that naturally release GLP-1.\u00a0<\/span><\/p>\n

A small 2018 study of 26 men found that consuming 2 grams per day of phytosterols and 10 grams per day of inulin via enriched soymilk led to<\/span> significant increases in GLP-1 secretion<\/span><\/a>, though glucose levels did not improve significantly.<\/span><\/p>\n

Psyllium husk, a popular type of soluble fiber, may improve satiety and reduce post-meal glucose spikes. A 2023 systematic review found that psyllium<\/span> improved glycemic control<\/span><\/a> and aided in weight loss.<\/span><\/p>\n

Where soluble fiber falls short as a GLP-1 supplement is that it cannot fully mimic a GLP-1 prescription in terms of appetite and craving suppression, weight loss, or GLP-1 production.<\/span><\/p>\n

If you’re currently taking a GLP-1 medication and want to add fiber as a supplement, keep in mind that the prescription already slows digestion. Too much fiber may cause nausea, bloating, or constipation. You could start by eating<\/span> foods that naturally increase GLP-1<\/span><\/a>, such as legumes, oats, and vegetables.<\/span><\/p>\n

Berberine<\/span><\/h3>\n

Berberine<\/span><\/a> is a plant-based compound sometimes marketed as \u201cnature\u2019s Ozempic,\u201d but that comparison is misleading.<\/span> Lab and animal research suggest berberine may influence GLP-1 secretion<\/span><\/a>, and some studies suggest it may support blood sugar control and metabolic health.<\/span><\/p>\n

However, there is no strong evidence that berberine reliably raises GLP-1 in humans, and it has not been shown to produce the same weight-related effects as prescription GLP-1 medications.<\/span><\/p>\n

Talk to your healthcare provider if you\u2019re taking a<\/span> GLP-1 or <\/span>dual GIP\/GLP-1 receptor agonist<\/span><\/a> (Mounjaro\/Zepbound) and are interested in taking berberine. Berberine may lower blood sugar, which could increase the risk of hypoglycemia, especially if you also use insulin or other diabetes medications.<\/span><\/p>\n

Curcumin<\/span><\/h3>\n

A bright-yellow plant compound found in turmeric, curcumin is commonly found in GLP-1 supplements. A<\/span>\u00a0lab study<\/span><\/a> found that animal cells exposed to curcumin showed a significant increase in GLP-1 secretion. A<\/span> separate study<\/span><\/a> also found that curcumin and its oxidative breakdown products boosted GLP-1 release in mice.\u00a0<\/span><\/p>\n

Most of the evidence surrounding curcumin and GLP-1 comes from lab or animal testing rather than from human clinical trials. There is also no evidence that curcumin can mimic the appetite, blood sugar, or weight-related effects of prescription GLP-1 medications.\u00a0<\/span><\/p>\n

Curcumin is generally a well-tolerated supplement, even for those already taking a GLP-1 medication. However, you may experience some common side effects like nausea and bloating. Also, if you\u2019re currently taking diabetes medications or anticoagulants (blood thinners), make sure to get medical advice from your healthcare provider before starting curcumin.<\/span><\/p>\n

Probiotics<\/span><\/h3>\n

If you pick up a GLP-1 supplement, you’re likely to find probiotics, specifically Lactobacillus strains. Probiotics are known for altering the gut microbiome and may increase the production of short-chain fatty acids (SCFAs). These compounds, such as acetate, butyrate, and propionate, may stimulate the L cells in your intestine that release GLP-1.<\/span><\/p>\n

In one <\/span>study<\/span><\/a>, researchers fed diabetic rats human lactobacilli engineered to secrete GLP-1, and the rats showed improved insulin levels. There is also<\/span> evidence<\/span><\/a> that certain Lactobacillus strains may influence metabolic markers, including abdominal fat, in humans.<\/span><\/p>\n
