Proven by Science

The Landmark Health Study is one of the most extraordinary studies of long-term supplement usage. Over a 10-year period, we tracked people who’d taken multiple Shaklee supplements for up to 50 years, and they showed significantly healthier biomarkers than people who took a single, non-Shaklee supplement or no supplements at all. The results were truly remarkable.

In the Landmark Health Study, Shaklee users had*:


Higher Levels of
Key Nutrients

Our users had higher levels of such key nutrients as vitamin D, folate, and vitamin B121,2


Healthier Key

Our users had significantly healthier biomarkers related to cardiovascular, heart, and cognitive health1,2

*Percentages reflect Shaklee supplement users compared with non-supplement users. Data for nonusers was obtained from NHANES 2001-2002 and NHANES 1988-1994. Long-term Shaklee users clearly demonstrated lower levels of the most important heart-health biomarkers recognized by the American Heart Association.
