蛋白质补充产品在青少年中的使用日趋普遍。密歇根大学2024年的一项代表性调查显示，在近1000名家长的受调者中，近半数表示其13-17岁子女在过去一年内消费过蛋白质产品1。同时，蛋白质产品市场需求旺盛，2024年3月至2025年3月间，德国健身蛋白质产品市场零售收入增长约25%1。
然而，专业机构对青少年过量摄入蛋白质提出了健康隐忧。德国营养学会建议，健康成人每天每千克体重摄入0.8克蛋白质，青少年应为0.9克/千克体重1。但根据2015-2017年的德国研究数据，约半数6-17岁儿童和青少年的蛋白质摄入量已超过建议量的两倍1。长期过量蛋白质摄入可能导致肾脏损伤、肥胖和提前进入青春期等风险，特别是在饮水不足或肾脏已有损伤的情况下风险更高1。
专家认为，青少年无需特殊蛋白质补充剂即可满足营养需求，通过优化正常饮食足以达成目标1。仅当日训练超过5小时的运动员才应根据训练强度摄入1.2-2克蛋白质/千克体重1。此外，德国科隆体育大学曾发现某些蛋白质产品含有违禁物质1，进一步引发了产品安全性的问题。
Nearly half of teenagers aged 13 to 17 consumed protein products over the past year, according to a 2024 University of Michigan survey of nearly 1,000 parents 1. This surge in consumption comes as Germany's fitness protein market experienced approximately 25 percent retail revenue growth between March 2024 and March 2025 1. However, health experts warn that excessive protein intake among adolescents carries significant risks.
The German Nutrition Society (DGE) recommends that healthy teenagers consume 0.9 grams of protein per kilogram of body weight daily, compared to 0.8 grams for adults 1. Research from 2015 to 2017 found that approximately half of German children and adolescents aged 6 to 17 were consuming more than twice the recommended protein intake 1. Prolonged overconsumption of protein may cause kidney damage, obesity, and premature onset of puberty, with heightened risks when water intake is inadequate or existing kidney damage is present 1. Additionally, researchers at Germany's Cologne University of Sport discovered that certain protein products contained banned substances 1.
Nutrition professionals emphasize that optimized regular diets can meet adolescent nutritional requirements without specialized protein supplements 1. The DGE specifies that only athletes engaging in training exceeding five hours daily should consume 1.2 to 2 grams of protein per kilogram of body weight, tailored to training intensity 1.
