Terranova Green Child Vitamin D3 400IU (10 µG) is a natural food supplement made for children aged 4-12 years old. Vitamin D3 is one that is not found in many foods, so the body’s main source of it is from sunlight, which causes the production of it in the skin. This supplement is perfect for the winter months, where sunlight hours are reduced, and it’s too cold to remain outdoors for long. Vitamin D3 is required to maintain good bone health, and a deficiency can lead to problems like low bone mineral density, which leads to an increased risk of fractures. This vitamin D3 is extracted from a vegan friendly strain of edible lichen, and each capsule features no fillers, binders or artificial additives.
