By Bruce Brightman – Founder – LifeSource Vitamins

At LifeSource Vitamins, quality is not just a claim — it is part of how we do business. Since 1992, we have worked to provide premium supplements with a deep commitment to transparency, consistency, and trust. One of the most important ways we support that promise is through independent third-party testing.*

Every LifeSource Vitamins product is reviewed to help confirm that what is listed on the label matches what is in the bottle. That includes testing standards focused on identity, potency, purity, and label accuracy before products reach our customers.*
