I have just been told my vitamin D level is very low. Are there any underlying health conditions that could cause this?
Good question! We don't think so! Most people have developed vitamin D deficiency over the last 20-30 years based on changes in our diet and our environment. It is probably a reflection of a world and not a malabsorption issue.
If there are other concerns that would raise a question of malabsorption we always recommend talking to your physician, but isolated low vitamin D is now (unfortunately) very common.
