Several leading protein powder OEM manufacturers have recently jointly launched a special "small-batch flexible customization" service, lowering the minimum order quantity of conventional protein powder products from the traditional 50,000 cans to 5,000 cans, and opening supporting services such as formula fine-tuning and personalized packaging customization, as well as value-added services such as free formula optimization consultation and packaging design guidance for start-up brands. This service accurately meets the trial sales needs of niche brands on new channels such as Douyin and Xiaohongshu, greatly reducing the capital threshold and trial and error cost for new brands to enter the protein nutrition track. In the second quarter of 2026, relevant small-batch orders increased by 120% year-on-year, helping more than 70 start-up health brands quickly enter the protein nutrition track in an asset-light mode. Many niche brands born relying on this service have achieved monthly sales exceeding one million within half a year of launch, further activating the innovation vitality of the protein nutrition track.
