Nutrient Quality100

Ingredient Transparency80
The vitamin D amount and D3 form are clearly stated. The separate proportion detail is not given, although the named forms both identify vitamin D3.
Value For Money80
The vitamin D amount offers good value for the serving cost. That is useful when vitamin D is the nutrient you specifically want to add.
