Nordic Berries contains vitamin D3 (cholecalciferol), a form that naturally occurs in animal sources such as lanolin (wool fat). D3 is often used in supplements because of its good absorbability. Note: because of this, the product is not vegan, but it is vegetarian.

RRR-alpha-tocopherol is the natural form of vitamin E. This form is also found in foods such as sunflower oil and nuts. It is often used in supplements because it is stable and naturally occurring.

Inositol is a substance that naturally occurs in fruit, grains, and nuts. It is related to B vitamins and is sometimes added to children's multivitamins as a supplement to other nutrients. The amount in this product is small (10 mcg per daily dose).

Magnesium and calcium take up a lot of space in supplements. Because these gummies are small and chewable, there is limited room for large amounts of these minerals. For higher doses, separate supplements are available.

Zinc citrate is a commonly used, well-absorbed form of zinc in supplements. It is gentle on the stomach and is often used in children's multivitamins.

Some of the vitamins are natural (such as vitamin E and D3), others are added in standardized, synthetic forms (such as vitamin B12 and folic acid), as is often the case in multivitamins.
