NSF® International

An independent global public health organization.

NSF® audits manufacturers to ensure compliance with GMP Requirements—guidelines that provide a system of processes, procedures, and documentation to assure that a product has the identity, strength, composition, quality and purity that appear on its label. Twice a year, NSF® audits all production facilities that manufacture, package, warehouse and distribute dietary supplements and functional foods to review:

  • Quality control testing procedures for raw materials and finished products
  • Maintenance, housekeeping, cleaning and sanitization procedures
  • Sourcing and traceability procedures
  • Training and qualification programs
  • Internal SOPs and product recall procedures

98% of our customers recommend us to family and friends. We’re very proud of that. Why? Because the health of our loved ones matters to us even more than our own—and we’re willing to bet you feel the same way.

If you don’t like our products, we want to hear from you. Here’s why: U.S. supplement manufacturers like Life Extension® are required to catalog and investigate customer complaints. Your feedback makes us stronger.

We hope you’ll take our supplements for life. But if for whatever reason one of our formulas doesn’t agree with you, send it back. We’ll refund your purchase price for up to a full year—doesn’t matter how many doses are left.
