Myth: Vitamin D levels should be checked for everyone.
Your vitamin D levels must be within the recommended range to ensure healthy health. Adults require 20 to 30 nanograms (ng) per milliliter (ng/mL) of vitamin D in their blood, according to the NIH. Even though a test is required to determine whether your levels are in that range, doing so is not required unless you have a condition like osteoporosis, according to the Cleveland Clinic.
