Berberine: It’s Not “Nature’s Ozempic®”

Social media played a key role in popularizing the semaglutide-based drug Ozempic® as an off-label weight loss drug, which eventually caused shortages. This unavailability – as well as the high cost of these commercial drugs – led patients to seek alternatives like compounded semaglutide, despite its risks. Now, social media influencers have turned their attention to berberine, a naturally-derived supplement that they’ve dubbed “Nature’s Ozempic®.” However, as is often the case with “all-natural” supplements, greater scrutiny reveals that berberine may not be as effective as social media influencers claim it is – and it’s definitely not without potential for risks.

Why are patients using berberine?

Even after Ozempic® was made available again, some patients experienced numerous side effects, including the dreaded “Ozempic® face.” Due to the gamut of side effects (gastrointestinal upset, constipation, etc.) and because Ozempic® is incredibly expensive and typically not covered by insurance when used off-label, patients sought cheaper alternatives. One such alternative is berberine, which can be obtained at a fraction of the cost and without a prescription. Social media followers and the general public have been led to believe that all-natural weight loss supplements like berberine are safer alternatives to drugs that have been approved by the Food and Drug Administration (FDA) and often view them as equivalent to food.

There is limited research that shows that berberine acts similarly to Ozempic®.

As a supplement, the efficacy of berberine hasn’t been verified by the FDA’s rigorous clinical trial process, as approved drugs like Ozempic® have. In the absence of FDA approval, we have to rely on clinical experience and fundamental clinical research, most of which has yet to provide compelling evidence. Some research has suggested that berberine may not even be effective at the doses at which patients are ingesting it due to its poor oral bioavailability. In several studies, the concentrations of berberine that have been demonstrated effective in in vitro studies are typically thousands of times greater than the doses most patients are ingesting.2–4 

The effects of berberine may be more similar to those of metformin than semaglutide although berberine’s mechanism of action is somewhat unclear. Some evidence has shown that it may help reduce blood sugar and lipid levels, and combining berberine with metformin might permit a lower dosage of each individual drug, which may help reduce the side effects of each alone. However, the evidence for this is not extensive, and most has been performed in murine models or in vitro.

Of course, there are safety risks as well.

Berberine is a naturally-occurring compound found in several plants, which may give patients the impression that it and other supplements are inherently safer than FDA-approved drugs.5 However, these two groups of compounds are not mutually exclusive, and many FDA-approved drugs that have been derived from plants still have the potential to cause adverse events. Because patients often take supplements without physician supervision and because the FDA cannot strictly regulate them, supplements potentially carry more health risks than other medical interventions.

Many patients take berberine without physician supervision.

Because supplements can be purchased over-the-counter (OTC) without a prescription, patients often take them without consulting their physician. Moreover, they are unlikely to inform their physicians that they’re taking them, even when asked,6 which creates the risk of drug-supplement interactions. Patients may also take megadoses due to the perception that “more is better,” but such high doses will likely increase the risk of adverse events such as diarrhea.7 

Supplement regulations are incredibly lax. 

In addition to the frequent lack of supervision from a licensed prescriber, supplements are a highly unregulated space and receive no oversight from the FDA except for post-market surveillance. Safety issues are typically only found after many severe adverse events are reported or after the FDA has found a violation during a facility inspection. This is a widespread problem, and many supplements often don’t contain exactly what’s on the label.8 FDA inspections have found supplements that contained potentially dangerous unapproved dietary ingredients in their formulations, either due to adulteration or inadequate purification and separation processes. 

The FDA inspections needed to identify these violations aren’t being performed often enough to catch everything, underscoring the importance of sourcing supplements from reputable pharmacies. Patients should take supplements under the guidance of a licensed prescriber, who should in turn source them from a licensed pharmacy like VLS Pharmacy and New Drug Loft.
