由于名人推动和“减轻暴食、改善皮肤、骨骼和肠道”这些说法，骨汤越来越受欢迎并成为养生饮品，但证据基础仍然很薄。其蛋白质理论上可提高如胆囊收缩素、肽YY和GLP‑1等饱腹激素并降低胃饥饿素，但研究并未显示骨汤能稳定提供足够这些成分以产生明确减重效果。
2025年6月发表在《Clinical Nutrition Open Science》的一项对64名肥胖成年人研究发现，在两次3周高骨汤饮食阶段后平均减重7.4公斤并伴有肌肉增加，但参与者全程进行轻度运动且没有对照组。2007年《Appetite》的一项研究发现，在午餐前先喝汤可使总热量摄入下降约五分之一，提示饱腹作用可能来自液体先导摄入本身而非骨汤特有成分；同样，皮肤、骨骼和关节支持的说法也不确定，因为其胶原蛋白水平通常低于补充剂试验中使用的剂量。
2024年《European Food Research and Technology》对30种骨汤配方的评估称结果总体与大众说法相矛盾，并指出其钙、铁、镁等矿物质含量较低，而氨糖和软骨素硫酸盐等成分对关节疼痛的证据也并不一致。2021年《Medicina》小鼠试验中，6只动物被喂牛骨汤、6只只喝水，然后诱导结肠损伤，对照组出现严重炎症和结构紊乱，而骨汤组仅中度损伤，但仍属初步结果；实际可得结论是骨汤通常安全且舒适，可能有益却证据稀缺，最明显的不利是对“钱包”的影响。
Bone broth has become more popular as a wellness drink due to celebrity promotion and claims that it reduces overeating and improves skin, bones, and gut health, but the evidence base is still thin. Its protein could in theory raise satiety hormones such as cholecystokinin, peptide YY, and GLP-1 and lower ghrelin, yet studies have not shown that bone broth reliably provides enough of these to produce clear weight loss.
A June 2025 Clinical Nutrition Open Science trial in 64 obese adults found an average 7.4 kg loss after two three-week bone-broth-rich phases, with muscle gain, but participants also did light exercise and there was no control group. A 2007 Appetite study found that soup preloads before lunch cut total caloric intake by about one-fifth, suggesting the fullness effect may come from liquid preloading rather than bone broth specifically; likewise, claims for skin, bone, and joint support are uncertain because collagen levels are usually below doses used in supplement trials.
A 2024 review of 30 bone broth preparations in European Food Research and Technology said findings generally contradicted popular claims, and noted poor mineral content (calcium, iron, magnesium), while compounds like glucosamine and chondroitin sulfate may have inconsistent joint-pain evidence. In a 2021 Medicina mouse study, six animals were given bovine bone broth and six received water before induced colonic lesions, with controls showing severe inflammation and distortion and the broth group only moderate damage, but this is preliminary; the practical takeaway is that broth is generally safe and comforting, with plausible but sparse benefits and wallet impact most obvious.
