GrassrootsHealth is adding new Collaborative Nutrient Research Projects to study the contribution of nutrients, lifestyle changes, products, services, or other measurable interventions, to see “Is it working for ME?” for groups as well as individuals within those groups. These collaborative research projects are a reliable way to clarify overall effectiveness of nutrient interventions on measurable outcomes — e.g., vitamin D and other supplements, devices or products, and their impact on vitamin D levels and health outcomes.
