Sourcing & Quality Assurance

At Premium Select Nutrition, quality doesn’t start in the manufacturing facility — it starts with the ingredients we choose. Every product begins with carefully selected raw materials sourced from trusted suppliers who meet the highest safety and quality standards.

Responsible Ingredient Sourcing

We partner only with suppliers who share our commitment to integrity and transparency. This means:

- Strict Supplier Vetting – Every supplier must meet rigorous requirements before we source from them.

- Global Quality Standards – Ingredients are evaluated against U.S. and international safety benchmarks.

- Traceability – Each ingredient can be traced back to its origin.

Pre-Production Quality Checks

Before ingredients ever enter production, they undergo independent testing and verification to confirm:

- Identity – Ensuring the ingredient is exactly what it claims to be.

- Purity – Screening for contaminants or unwanted additives.

- Potency – Verifying that the ingredient delivers the expected strength and benefits.

Ongoing Quality Assurance

Our quality process doesn’t stop once production begins. At every stage, we perform:

- In-Process Checks – Continuous monitoring throughout manufacturing.

- Post-Production Testing – Verification that each batch meets our standards before release.
