Step-by-Step Manufacturing Process

1. Consultation & Custom Formulation

Work with our R&D team to develop a unique sports supplement formula. Our sports scientists evaluate your target market’s training needs and performance goals, whether for strength athletes, endurance competitors, or general fitness enthusiasts. We determine optimal ingredient combinations based on training phase (pre-workout, intra-workout, post-workout) and recommend clinically effective dosages that deliver noticeable results without unnecessary fillers.

2. High-Quality Ingredient Sourcing

We source premium performance ingredients with documented sports applications and verified certificates of analysis. Our procurement team secures pharmaceutical-grade proteins with specified amino acid profiles, instantized BCAAs for superior mixability, and patented performance compounds with research validation. Each ingredient undergoes stringent testing for heavy metals, microbiological contaminants, and athletic banned substances before entering production.

3. Manufacturing & Quality Testing

Your sports nutrition supplements are produced using specialized equipment designed for the unique challenges of performance ingredients. Our protein processing preserves native protein structures through low-temperature handling, while our pre-workout manufacturing implements precise microdosing of stimulants and performance compounds. Each batch undergoes sports-specific quality testing including protein content verification, amino acid quantification, dissolution rate analysis, and stimulant verification.

4. Branding & Packaging

We offer athletic-focused packaging solutions including nitrogen-flushed protein containers that maintain freshness, specialized pre-workout tubs with humidity control, and performance-minded single-serve sachets for on-the-go training. Our packaging experts help develop appropriate serving size recommendations, exercise timing instructions, and performance-focused benefit statements that resonate with fitness consumers.

5. Fulfillment & Shipping

Our logistics team implements specialized handling procedures for different sports supplement categories, maintaining appropriate temperature and humidity controls for protein powders, pre-workouts, and amino acid products. For international shipments, we provide all necessary documentation for importing sports nutrition products, including protein content verification and stimulant certification required by various countries.

6. Compliance & Quality Assurance

GMP-Certified & FDA-Registered Facility

Our facility features dedicated production areas for different sports nutrition categories with specialized equipment for protein processing, pre-workout blending, and amino acid handling. We implement rigorous cleaning validation and allergen control protocols, critical for maintaining product integrity across diverse sports supplement categories.

Third-Party Testing

Each sports nutrition product undergoes comprehensive testing including protein fingerprinting, HPLC analysis of active compounds, dissolution and mixability testing, and stability analysis under various environmental conditions. We offer banned substance testing through certified programs like Informed Choice and NSF Certified for Sport to support marketing to competitive athletes.

Labeling & Compliance Support

Our regulatory experts navigate the complex requirements for sports nutrition products, including structure/function claims, protein calculation methods, and appropriate stimulant warnings. We provide guidance on compliant marketing language for performance benefits while ensuring all labels meet FDA, FTC, and sports governing body regulations.
