A European sports nutrition brand planned to develop a functional powder combining joint flexibility and exercise recovery for fitness enthusiasts and those engaging in high-intensity exercise.

• Hyaluronic acid easily absorbs moisture and clumps in the powder, affecting its flowability.
• Inconsistent dissolution occurred when mixed with collagen.
• The product had a slightly sticky texture, affecting the drinking experience.

• Recommended to use low molecular weight hyaluronic acid (approximately 50 kDa) to improve solubility.
• Optimized the premixing process, mixing it evenly with the carrier powder before adding other ingredients.
• Controlled the addition ratio within a reasonable range to avoid excessive viscosity.
• Provided stable batches of raw materials to ensure production consistency.

• The powder's flowability was significantly improved, with no obvious clumping issues.
• Dissolving speed increased, resulting in smoother mixing with cold water.
• End-user feedback indicated "better joint comfort after exercise," leading to increased repurchase rates.
• The product successfully entered gym channels and cross-border e-commerce platforms for sale.
