                                According to the National Institutes of Health, the Recommended Dietary Allowance (RDA) for most adults is 600 IU, making the question 'Can I take 200 IU of vitamin D?' a critical one for many. While a 200 IU dose is generally safe, it falls far short of the established daily recommendation for maintaining proper bone health and other vital bodily functions for most adults.
