Quality, Purity & Efficacy

We focus on three specific areas.

  • Raw Materials: Unlike other supplement companies, the ingredients that go into our supplements are not chosen based on cost. Instead they are chosen based on purity (to ensure contaminants such as microbes and heavy metals comply with regulatory and GMP requirements), potency, and usage in successful scientific research.
  • Validation of the Efficacy of Ingredients by Scientific Research: We use ingredients and dosages that accurately replicate the most successful results obtained in scientific studies for maximum efficacy.

Yes. All active ingredients from patented, scientifically validated raw materials as well as final, finished products are verified using advanced analytical methods such as HPLC (high performance liquid chromatography), MS (mass spectrometry), etc., to ensure each and every product accurately meets label claims in strict compliance with our demanding product specifications.

Where Life Extension is concerned, yes. Patented materials validated in scientific studies cost more — period. In contrast with many commercial brands focused on driving up margins by using the cheapest raw materials available, Life Extension collaborates with raw material suppliers who invest in scientific validation of their ingredients, which increases material costs. With Life Extension products, you get the quality you pay for.

They are inactive ingredients (excipients) that play a number of critical, essential roles in the manufacturing process including:

  • Achieving uniform density for accurate dosing
  • Dispersing the active ingredients evenly throughout a solid tablet, capsule, and softgel
  • Protecting active ingredients from rapid inactivation due to heat and moisture
  • Promoting tablet disintegration, as well as capsule and softgel dissolution
  • Sustaining the release of active ingredients into the body over time

Sophisticated products require sophisticated delivery systems. The best companies choose the most effective finished form based on the characteristics of the raw materials, and the desired disintegration or dissolution characteristics of the finished product and the active ingredients.
