所谓的天然GLP-1补充剂，真的能当自然版司美格鲁肽吗？

Core Viewpoint - GLP-1 class weight loss drugs are reshaping global perceptions of weight management, demonstrating weight loss of 10% or more in clinical and real-world studies, while natural GLP-1 supplements are gaining popularity as milder alternatives [4][10] Mechanism of Action - GLP-1 is a hormone secreted by the intestines after eating, which stimulates insulin release, delays gastric emptying, and acts on the brain's appetite center to reduce hunger [4][10] - True GLP-1 receptor agonists are structurally modified to provide sustained, stable, and high-intensity activation of GLP-1 receptors, which is crucial for their significant weight loss effects [4][10] Natural GLP-1 Supplements - Natural GLP-1 supplements are not true GLP-1 or receptor agonists; they attempt to influence metabolic environments through indirect pathways, such as stimulating small amounts of GLP-1 release and improving gut microbiota [6][9] - Common ingredients in these supplements include psyllium husk, green tea extract, saffron extract, polyphenols from lemon or blood orange, various probiotics or prebiotics, and amino acids [7][9] Efficacy and Evidence - There is currently no convincing evidence that natural GLP-1 supplements can achieve weight loss effects comparable to pharmaceutical-grade GLP-1 receptor agonists; their impact is often limited to mild appetite reduction or improved eating control [9][10] - Increasing protein intake is emphasized as a more reliable strategy for stimulating endogenous GLP-1, with recommendations of 1.2 to 1.5 grams of protein per kilogram of body weight per day [9][10] Safety and Regulation - The supplement industry is loosely regulated, leading to issues such as inconsistent ingredient labeling, potential liver function abnormalities from plant extracts, and interactions with existing medications [9][10] - Some products may contain stimulants like caffeine, which could increase cardiovascular or neurological burdens, especially for individuals with chronic diseases or metabolic disorders [9][10] Conclusion - Natural GLP-1 supplements are not entirely ineffective but are better positioned as auxiliary tools in health management rather than core weight loss treatments; the most effective and evidence-backed option remains the regulated use of GLP-1 class drugs [10]
