Join KamaLama’s Mission

KamaLama.org is an independent science-based company dedicated to helping people live healthier, longer lives.

We don’t buy into hype—no miracle cures, fad diets, or flashy supplements.

KamaLama is grounded in science, relying exclusively on high-quality evidence from double-blind, randomised, placebo-controlled trials.

By collecting and distilling scientific insights on longevity, KamaLama created a simple test that shows how each factor—individually and collectively—can influence life expectancy. It provides a complete 360° health overview of indicators and behaviours such as physical activity, sleep quality, metabolic health, mental well-being, social connection and more.

Individuals who complete the assessment receive a personalised report showing how these behaviours and conditions may influence their expected lifespan.

This information is not medical advice, but a science-based tool designed to support informed decision-making and help prioritise health-improving actions.

As a mission-driven and independent organization, KamaLama values all forms of support—from sharing the test link to offering expertise or making donations.
