What is inositol and how is D-chiro-inositol different?
The word "inositol" refers to a family of closely related substances and often refers to the most common available form, myo-inositol.
D-chiro-inositol is a very special member of that family. The body needs DCI when responding to insulin, and DCI is difficult to get from diet. Therefore, the human body has to make DCI. Some people's bodies are not efficient at making DCI, and they can develop symptoms of insulin resistance and Polycystic Ovarian Syndrome (PCOS) as a result.
What are pinitol and myo-inositol?
These are other forms of inositol. Like DCI, they myo is important for insulin response. But unlike DCI, both of these forms of inositol are fairly easy to get from diet.
You can read more about the important differences between myo inositol and DCI, as well as thoughts on the combined therapy of myo and DCI, in the following two articles:
