1. Promotes strong bones and teeth: Vitamin D3 is essential for the absorption of calcium and phosphorus, which are crucial for maintaining strong bones and teeth. This can help prevent conditions like osteoporosis and tooth decay.
2. Boosts immune system: Vitamin D3 has been shown to play a vital role in supporting the immune system. It helps regulate the production and activity of immune cells, which can help defend against infections and diseases. Regular intake of Vitamin D3 Plus can strengthen the immune system and promote overall health.

The Active Ingredient Is: Vitamin D3 (Cholecalciferol)

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin important for healthy bone health and immune function.

This form is a naturally produced vitamin in the skin and is activated by metabolic processes in the body; in this formulation vitamin D3 teams up with magnesium to support calcium handling for bone maintenance, with calcium and vitamin C helping collagen formation.

What Does Vitamin D3 Do?

Vitamin D3 helps regulate calcium absorption and supports normal immune function and muscle function, contributing to bone health overall.

EFSA-aligned guidance says that vitamin D3 can support these normal physiological roles as part of a balanced diet.
