Overview

Natural Factors Vitamin D3 400 IU is a dietary supplement presented as a chewable tablet with a strawberry flavor. Each tablet provides vitamin D3 at a strength of 400 IU and is formulated for children 4 years and older. The product is suitable for vegetarians and is described as purity- and potency-guaranteed.

Vitamin D3 plays an important role in helping the body absorb calcium from food, which supports healthy bones and teeth. Because calcium balance is also linked to normal immune function as well as the maintenance of healthy nerves and muscles, this formula is positioned as a straightforward vitamin D supplement for everyday support.

The tablet is sweetened with xylitol and is designed to be chewed rather than swallowed whole. Quality-related claims in the source also note non-GMO documentation through Isura and mass spectrometry testing.
