From the Guidelines
Berberine, apple cider vinegar, fiber supplements like psyllium husk, gymnema sylvestre, and cinnamon are among the supplements that have been studied for their potential to mimic the effects of GLP-1, although none match the potency of prescription GLP-1 agonists like semaglutide or liraglutide 1. When considering supplements that mimic GLP-1, it's essential to prioritize those with the most robust evidence. Berberine, for instance, has been shown to activate AMPK pathways similar to metformin, which may improve insulin sensitivity 1. The recommended dosage of berberine is typically 500mg 2-3 times daily with meals.
Key Considerations
- Apple cider vinegar (1-2 tablespoons diluted in water before meals) may help regulate blood sugar and increase satiety, although the evidence is largely anecdotal.
- Fiber supplements like psyllium husk (3-5g before meals) can slow gastric emptying and promote fullness, similar to one mechanism of GLP-1 drugs.
- Gymnema sylvestre (200-400mg daily) may reduce sugar cravings and help with glucose metabolism, but more research is needed to confirm its efficacy.
- Cinnamon (1-6g daily) has shown modest effects on blood sugar control, but its impact on GLP-1 pathways is less clear.
Important Notes
It's crucial to note that while these supplements may offer mild benefits for blood sugar control and appetite regulation, they cannot replicate the significant weight loss and metabolic improvements seen with prescription GLP-1 medications, such as semaglutide or liraglutide, which have been shown to reduce weight and improve weight-related comorbidities significantly 1. Before starting any supplement regimen, especially if you have diabetes or other health conditions, it's essential to consult with a healthcare provider. A low-carbohydrate diet and regular exercise should also be combined with these supplements for best results.
From the Research
GLP-1 Receptor Agonists
- GLP-1 receptor agonists (GLP-1 RAs) are a class of drugs that mimic the effects of the incretin hormone GLP-1, which is released from the intestine in response to food intake 2.
- They have been shown to be effective in improving blood glucose control, with additional benefits of preserving beta-cell function, weight loss, and increasing insulin sensitivity 2.
- Examples of GLP-1 RAs include exenatide, liraglutide, albiglutide, dulaglutide, and semaglutide 3, 2.
Supplements that Mimic GLP-1
- Berberine metabolites, such as berberrubine and palmatine, have been shown to stimulate GLP-1 secretion by alleviating oxidative stress and mitochondrial dysfunction 4.
- These metabolites may have potential therapeutic effects on GLP-1 secretion and glucose tolerance, and could be considered as supplements to mimic GLP-1 4.
Mechanisms of Action
- GLP-1 RAs work by increasing insulin secretion, decreasing glucagon release, increasing satiety, and slowing gastric emptying 3, 2.
- They also have effects on gastric emptying, calorie intake, and body weight, and may have potential benefits for cardiovascular health and renal complications 3.
Safety and Tolerability
- The safety and tolerability of GLP-1 RAs have been extensively studied, and they are generally well-tolerated with a low risk of hypoglycemia and other adverse events 5.
- However, gastrointestinal adverse events, such as nausea and vomiting, are common, and injection-site reactions and pancreatitis have been reported in some cases 5.
