What is the recommended daily intake (RDI) for Vitamin D?
Vitamin D is mostly found in animal products; remember also that the skin converts the sunlight to Vitamin D3 via activation through the liver and kidneys. There is much concern these days about sunlight causing skin cancers, however small amounts (10-15 minutes) of direct sunlight in the mornings and afternoons is a sufficient amount to increase Vitamin D levels (approximately up to 20 000IU of Vitamin D3). Recommended daily intakes (RDI) – Recommendations by life stage and gender according to NHMRC.
