Quality & Testing

Tested like a serious daily supplement.

Lester is built to be taken every day, for years — so every batch is held to a standard that matches that commitment.

Every batch is tested for

• Active ingredient levels — confirming the plant sterols and other actives are present at label amounts
• Heavy metals
• Microbials
• Stability — potency and texture over time, not just on the day it's made
• Allergen controls

How it's made

• Manufactured in a cGMP, FDA-registered facility
• Third-party tested
• Vegan, pectin-based — no gelatin
• Zero added sugar, no sugar alcohols, no artificial colors
• Formulated with overages so the product meets its label through the end of its shelf life

Certificates of Analysis

Batch testing results are produced with every production run. Certificates of Analysis will be available here at launch.

Built for the long run

Plant sterols and a gummy format can be a challenging combination to keep stable and pleasant over time. We test for potency and texture across the product's shelf life — because a supplement only works if you keep taking it.
