RAE. Ever heard of it? It’s “retinol activity equivalent” and it’s the new way we talk about vitamin A. Basically vitamin A is important because it’s a source of a molecule called “retinol.” This is the active ingredient that your eye uses to process light. Converting vitamin A from IUs into the new “RAE” unit is easy. We are just converting the IU to mcg or “micrograms.” All you need to do is take the IU and multiply by 0.3 and you will get the mcg RAE. For example: Thus, people who have medical conditions that reduce fat absorption are prone to vitamin D deficiencies.

However, people who don’t live in sunny countries need to consume more vitamin D through foods and supplements ( 26). But, what’s the difference between IU and ug? If they both measure the same thing, why are they used interchangeably?

The Vitamin D Council considers these levels to be 'normal to high'. These vitamin D levels can be achieved by exposing the skin to adequate sunlight. As a result, it is assumed that these are natural, healthy levels. Your value is between 80 - 100 ng/mlSometimes the amount of vitamin D is expressed as International Units (IU). 1 microgram of vitamin D is equal to 40 IU.

Advice for adults and children over 4 years old If you suffer from a disease that makes it absolutely necessary for your vitamin D level to be in the optimal range, or if you want to know your exact level, then you should have your vitamin D level measured.

The recommendations are based on the findings of Dr. John J. Cannell, a vitamin D expert and founder of the Vitamin D Council organization. A vitamin D deficiency can only be discovered through blood tests that measure levels of storage vitamin D, known as 25(OH)D. Some people will not make enough vitamin D from sunlight because they have very little or no sunshine exposure.
