About this product
Est 1967May Support Immune, Bone & Muscle HealthDietary SupplementMason Guarantee - Laboratory TestedcGMP Certified Good Manufacturing PracticeGluten FreeVitamin D3 is a popular supplement because it plays an important role in many different processes within the body. First, it acts as a shuttling nutrient; meaning that it helps to shuttle other nutrients like calcium and phosphorus through intestinal walls and into the bloodstream. Without Vitamin D’s help, neither mineral could find their way to help build new bones or repair existing ones, so it may be critical for healthy bone density and bone strength. Vitamin D3 isn’t just an essential nutrient for healthy bones. It is also known for helping to support healthy immunity as well. Without it, important immune cells such as T-lymphocyte (T-cells) would not develop fully or function properly. While our bodies do produce Vitamin D, many people choose to supplement with this important nutrient because it plays such a vital role in supporting optimal health and wellness.
