Vitamin

Vitamin d

Vitamin D2, or ergocalciferol, is produced from fungal or yeast sterols exposed to ultraviolet light. The body converts it through liver and kidney pathways into active vitamin D metabolites.

It supports normal calcium absorption, bone maintenance, muscle function and immune activity.

In everyday life, Vitamin D supports calcium absorption, resilient bones and healthy muscle function through a vegetarian-suitable vitamin D source.

Its nutritional contribution depends on the amount provided and overall dietary intake.

Ingredient overview

What it is

Vitamin D2, or ergocalciferol, is produced from fungal or yeast sterols exposed to ultraviolet light. The body converts it through liver and kidney pathways into active vitamin D metabolites.

  • Scientific identity: Vitamin D; molecule: Ergocalciferol, vitamin D2.
  • How it works: Derived from fungal sterols: Ultraviolet treatment of ergosterol from yeast or fungi produces ergocalciferol, vitamin D2. Absorbed with dietary fat: Being fat-soluble, uptake improves markedly when it is taken with a meal containing fat.
  • Primary function: It supports normal calcium absorption, bone maintenance, muscle function and immune activity.
  • What it supports: Vitamin D supports calcium absorption, resilient bones and healthy muscle function through a vegetarian-suitable vitamin D source.
  • Important consideration: Its nutritional contribution depends on the amount provided and overall dietary intake.

Formulation rationale

Why we use it

CARPEDIEM selected Vitamin D for a clearly defined role within a thoughtfully balanced formulation.

  • Formulation purpose: It supports normal calcium absorption, bone maintenance, muscle function and immune activity.
  • Used in: CARPEDIEM MultiMen, CARPEDIEM MultiWomen and CARPEDIEM Family Daily Essentials Pack.
  • Works alongside: Vitamin D contributes its own defined scientific role within the complete formulation.
  • Meaningful contribution: Vitamin D supports calcium absorption, resilient bones and healthy muscle function through a vegetarian-suitable vitamin D source. Contributes to healthy bones, teeth and the maintenance of skeletal mineral balance.
  • Quality and scientific context: Its nutritional contribution depends on the amount provided and overall dietary intake. 1 ingredient-specific study is included because the research reports a relevant benefit.
