ProHealth FundraisingFunding Research to Find Cures
Knowing that research is the key to finding cures for chronic, debilitating diseases, ProHealth has raised and donated more than $3.5 million to organizations researching fibromyalgia, ME/Chronic Fatigue Syndrome and other conditions.

You Help Make it Possible
As a crucial part of our mission, a portion of each purchase you make goes toward this fundraising effort. This is such a high priority that in some years our donations outpaced our profits. Thank you for helping support our efforts.
Mega D3 25K is a special formulation intended to assist with compromised vitamin D levels. It offers support for healthy bones, through better calcium absorption, helps combat fatigue, and assists the immune system with cellular growth regulation.*

Vitamin D, a fat-soluble vitamin, is essential to maintaining total body health, yet is not found in many foods. It's needed to keep bones and teeth strong over your lifetime, and to ensure the proper functioning of heart, muscles and nerves - it even helps your blood to clot. We developed this product using vitamin D3 or cholecalciferol, which is the same type of vitamin D your body makes when exposed to sunlight and is also the version used to fortify foods.

With over 70% of the population deficient in Vitamin D levels it is important that you supplement your diet with a high-quality D3 vitamin. Each day we are learning more about the amazing benefits of Vitamin D.

A growing body of research suggests this powerful nutrient may:

  • Promote a healthy immune system

  • Help prevent certain cancers*

  • Alleviate fatigue* - common with FM, ME/CFS, diabetes & other chronic conditions

  • Help reduce inflammation* and pain*

  • Boost calcium & phosphorus absorption and for healthy bones and teeth

  • Improve cardiovascular health

  • Support blood sugar management

  • Promote health muscle functions
