It takes an average of 17 years for research to become standard practice.

We can’t wait!

The vitamin D research shows that blood levels in the range 40-60 ng/ml (100-150 nmol/L) are safe, effective and will lower overall disease incidence and health care costs. GrassrootsHealth is committed to having vitamin D testing and monitoring be part of every yearly physical, for all age groups.

Take control of your health

Educate yourself on the benefits of vitamin D levels in the recommended range of 40-60 ng/ml. If you would like to see if it would improve your health, then you need to find your baseline level. The average level in the US is 22 ng/ml, well below the recommended range. Join D*action and screen your vitamin D level from home.

How do we achieve this?

By starting with project implementations in specific areas – to show it is safe and effective.

GrassrootsHealth is not just another health web site.

Instead it is the amalgamation of many vitamin D scientists from around the world and across many disciplines.

48 scientists worked together to create our call to action.

48 scientists have agreed that there is no perfect supplement amount, instead blood levels must be tested, and that level should be 40-60 ng/ml (100-150 nmol/L).

Much research, not just one study, is behind our mission to make vitamin D testing and monitoring part of standard of care for ALL people.

GrassrootsHealth started with D*action

D*action is a world-wide cohort of over 10,000 self-subscribed individuals wishing to take health into their own hands.

In 2012 we launched Protect our Children NOW!

Protect our Children NOW! is our project to end vitamin D deficiency where is starts – in utero.

All implementations are research projects, and we publish research based on our findings.
