Soon after I discovered that typical guidelines about iodine are outdated and wrong (1), I came across information about vitamin K that made me realize the amounts I had been experimenting with were pathetically small. Also, it is possible that vitamin D supplements affect vitamin K, which for me would explain a lot (2). This is yet another example of how difficult it is to find reliable info about all the nutrients and how they work in the body and interact with each other.
Here’s a diagram of how I suspect my iodine, vitamin K, vitamin D, zinc, and iron deficiencies have been interacting.
1: You can find a list of iodine references at the bottom of this Breast Cancer Choices’ iodine investigation page.
2: From the World’s Healthiest Foods vitamin D page:
“Vitamin D helps to regulate the production of certain calcium-binding proteins that function in the bones and kidneys. Because these binding proteins are also dependent on vitamin K, interrelationships between vitamin D and vitamin K have become the subject of active research investigation.”
