Vitamin D

Item# VTD10
1 Bottle

Vitamin D supplementation has been one of my top recommendations for over 30 years. This fat-soluble vitamin is critical for everything from immune health to bone strength and cardiovascular function. More research supporting its health benefits emerges every day. But it’s almost impossible to get enough from the foods you eat—and over one-third of Americans have been shown to have low vitamin D. Particularly during winter months, when it’s impossible to get enough sunlight for our bodies to manufacture the vitamin D we need, vitamin D supplementation is crucial.

Vitamin D for immune health.

Vitamin D plays an important role in boosting immune system health by increasing the activity of natural killer cells and T cells. Vitamin D for bone health. Also essential for bone health, vitamin D shuttles calcium into your bones and prevents calcium loss. Without it, no amount of calcium would be enough. That’s why vitamin D is critical for strong, supple bones. In addition vitamin D supports cellular integrity, improves muscle function and agility, enhances heart health, and even promotes proper blood sugar metabolism.

Vitamin D capsules help:

  • Boost immune system health
  • Activate natural killer and T cells
  • Shuttle calcium into bones and prevent calcium loss
  • Maintain strong, healthy bones
  • Support cellular health, muscle function
  • Enhance heart health
  • Promote proper blood sugar metabolism
