USANA Quality – A Commitment to Science, Purity and Excellence

When it comes to nutritional supplements, quality matters.

At Health Nutritionals, we believe you deserve supplements that are carefully researched, responsibly manufactured, and rigorously tested. That's why we're proud to offer USANA—one of the world's leading health and wellness companies with more than 30 years of experience in nutritional science.

USANA's commitment to quality extends far beyond meeting industry standards. From sourcing premium ingredients to advanced laboratory testing and state-of-the-art manufacturing, every step of the process is designed to deliver products you can trust.

Science-Based Product Development

USANA's nutritional products are developed by scientists with expertise in nutrition, biochemistry, molecular biology, and related health sciences.

Every formulation is based on current scientific research and is continually reviewed as nutritional science evolves. Rather than following short-term market trends, USANA focuses on developing products supported by evidence and designed to provide effective nutritional support.

Premium Ingredient Selection

Quality begins with the ingredients.

Before an ingredient is accepted for use, USANA evaluates suppliers against strict quality requirements. Raw materials are carefully selected and tested to help ensure they meet the company's specifications for identity, purity, potency, and safety.

Only ingredients that satisfy these quality standards move forward into production.

Manufactured Under Current Good Manufacturing Practices (cGMP)

USANA manufactures many of its nutritional supplements in company-owned facilities operating in accordance with the U.S. Food and Drug Administration's Current Good Manufacturing Practices (cGMP) for dietary supplements (21 CFR Part 111).

These regulations establish strict requirements for:

  • Manufacturing procedures
  • Quality control systems
  • Equipment maintenance
  • Employee training
  • Hygiene and sanitation
  • Documentation and traceability
  • Packaging and labelling

By manufacturing many products in its own facilities, USANA maintains close oversight of production and quality control throughout the manufacturing process.

Pharmaceutical-Quality Manufacturing Practices

Although USANA's nutritional supplements are regulated as dietary supplements rather than medicines, the company applies rigorous quality systems comparable to those used in pharmaceutical manufacturing.

These quality systems include:

  • Supplier qualification
  • Raw material verification
  • Ingredient identity testing
  • Potency testing
  • Heavy metal screening
  • Microbiological testing
  • Stability testing
  • Batch traceability
  • Comprehensive quality documentation
  • Multiple quality checkpoints before product release

This systematic approach helps ensure that products consistently meet USANA's quality specifications.

Extensive Laboratory Testing

Every production batch undergoes comprehensive testing throughout the manufacturing process.

USANA's quality assurance programme includes laboratory testing for:

  • Ingredient identity
  • Nutrient potency
  • Product purity
  • Microbiological safety
  • Heavy metals
  • Product stability
  • Finished product verification

Testing is performed using advanced analytical techniques to help ensure consistency, accuracy, and product integrity.

Independent Third-Party Verification

USANA also participates in independent verification programmes where appropriate.

For example, selected products have earned NSF Certified for Sport® certification, one of the world's most respected independent certification programmes for sports nutrition products.

Products carrying this certification are independently tested to verify label accuracy and screened for substances prohibited in competitive sports.

Please note that this certification applies only to selected products.

Continuous Research and Innovation

USANA continually invests in scientific research and product development to improve formulations and manufacturing processes.

By combining scientific expertise with ongoing innovation, USANA strives to provide nutritional products that reflect current nutritional knowledge and high manufacturing standards.

Independent Recognition by ConsumerLab.com

USANA's commitment to quality has also been recognised by ConsumerLab.com, an independent company that tests dietary supplements for quality, purity, and label accuracy.

ConsumerLab purchases products from the marketplace and evaluates them to determine whether they contain the ingredients listed on the label, provide the stated nutrient amounts, and meet standards for contaminants such as heavy metals where applicable.

Over the years, several USANA products—including products in the CellSentials® range—have received ConsumerLab.com Approved Quality recognition and have been selected as Top Picks in their respective categories.

Independent recognition from organisations such as ConsumerLab.com provides consumers with additional confidence that selected USANA products have met rigorous quality testing beyond the manufacturer's own quality assurance programme.

Please note: ConsumerLab evaluations apply to specific products tested at a particular point in time. Customers should refer to the latest ConsumerLab reports or official USANA information for current product evaluations.

Why Quality Matters

The quality of a nutritional supplement can influence its consistency, purity, and reliability.

High-quality manufacturing and testing help ensure that:

  • Ingredients match what appears on the label.
  • Products meet established quality specifications.
  • Manufacturing processes are carefully controlled.
  • Contaminants are minimised through rigorous testing.
  • Each production batch is evaluated before release.

These quality measures provide greater confidence in the supplements you choose for yourself and your family.
