A New Phase for GrassrootsHealth — Do You Know Someone Who Could Help Support Our Work?

---

For more than a decade, GrassrootsHealth has been dedicated to a simple but powerful mission:

To translate vitamin D research into practical solutions for improving public health.

Working alongside many of the world’s leading vitamin D scientists, we have helped bring attention to one of the most common and overlooked public health issues today – vitamin D deficiency.

Through research, education, and public engagement, our work has reached tens of thousands of individuals around the world. Yet the need for reliable information and practical solutions remains and continues to grow. As we enter our next phase, we are expanding several initiatives designed to make vitamin D optimization more accessible than ever.

New Initiatives at GrassrootsHealth

The CheckYourD Platform

We are launching an updated version of CheckYourD.org, offering vitamin D test kits in collaboration with OmegaQuant, designed to help individuals conveniently measure their vitamin D level without study requirement.  This option is great for practitioners, retailers, and individuals who want the easy at-home vitamin D testing without expecting their patients, clients, or customers to include their data in our study.  This option also directs individuals to follow our protocol:

1. Measure their vitamin D level
2. Calculate a personalized dose using the GrassrootsHealth Vitamin D*Calculator
3. Implement supplementation, sensible sunshine, and supportive nutrients
4. Retest to verify progress
5. Adjust and repeat until their target level is reached

This Dose-to-Target approach helps individuals move beyond guessing and toward personalized vitamin D optimization.  Learn more here.

Practitioner Continuing Education & Certification

We continue to expand our resources for health professionals, including:

• Our newly updated online course Moving Vitamin D Research into Practice: Addressing Vitamin D Deficiency to Improve Patient Outcomes, Population Health & Reduce Costs. (pending CEU approval for nurses and dietitians)
• Vitamin D* Certification programs for practitioners
• Downloadable guides and clinical resources

These programs help translate research into real-world practice and improve patient outcomes.

Expanded Online Presence & Digital Tools

We are also updating our website and developing new digital tools to help individuals and practitioners better understand and manage their vitamin D status, including:

• A new Vitamin D Protocol mobile app
• Updated website with enhanced community, scientist, and advocacy engagement, updated educational tools and resources
• New ways to expand the vitamin D message through all levels of engagement

These tools will make it easier than ever for individuals to apply the science of vitamin D in everyday life and move vitamin D research into practice.

How You Can Help

As a nonprofit research and education organization, GrassrootsHealth relies on the support of individuals, organizations, and mission-aligned partners who believe in the importance of our work.

We are currently seeking strategic partners and sponsors who share our vision for improving public health through evidence-based vitamin D education and optimization.

Potential collaborators may include:

• Supplement companies committed to quality and education
• Health technology companies

Partnerships can take many forms, and we look forward to developing strategic partnerships with like-minded individuals and organizations.
