As a compounding pharmacist with over 40 years of experience, our founder, Michael Lenzner R.Ph., has bridged the gap between prescription compounding and natural products manufacturing. We test our ingredients for purity and the final products for potency. We have trademarked a process called Rapid-Sorb, which enhances absorption of nutrients at the cellular level by as much as five to ten times. The bottom line for why MD’s and patients use Dr’s Advantage is our formulating expertise and use of the latest technologies and high-tech facilities, including a class 1000 clean room which showcases our dedication to high-grade, professional products. Dr’s Advantage Products are all formulated and manufactured in a FDA inspected facility located in Carlsbad, Ca.
