Aids Proper Immune, Bone, & Brain Health*

1MD Nutrition™ D3 enhances the body’s ability to absorb calcium, magnesium, and phosphorus, essential minerals for building and maintaining strong bones and teeth and ensuring healthy muscle function, while also activating key peptides in the immune system that help defend against harmful pathogens.*

Help Maintain a Healthy Mood & Proper Muscle Function*

  • Aptly named the “sunshine vitamin,” D3 is naturally synthesized when bare skin is exposed to UVB sunlight, but the modern indoor lifestyle limits this vital exposure. Clinical studies show that maintaining proper vitamin D levels can play an important role in bone and cardiovascular health, blood glucose balance, musculoskeletal strength, and neurological and immune system function.*

1MD Nutrition™ D3: Proven to Promote Musculoskeletal & Heart Health*

In clinical trials, significant improvement began at the 3-month marker.*

  • Month 1

    As levels of vitamin D serum increase, some may experience an improvement in muscular, immunity, and neural functionality.*

  • Month 2

    Higher serum levels of vitamin D appear to be significantly beneficial to cardiovascular and upper and lower respiratory tract health.*

  • Month 3 & Beyond 

    Normalizing a vitamin D deficiency with vitamin D 3 supplementation, over an extended length of time may promote normal cholesterol levels, enhance bone mineral density, and help alleviate daily stress.*
