Is Inositol Hexanicotinate the Same as Myo-Inositol?
No. Inositol hexanicotinate is not the same thing as myo-inositol. It is a compound made from inositol linked with niacin-related groups, and it is often marketed as a “no-flush niacin” product. That means it belongs more to the niacin supplement conversation than to the typical myo-inositol conversation around PCOS and fertility. (WebMD)
This is where people get confused. The name contains the word “inositol,” so shoppers sometimes assume it is just another form of the same supplement used for PCOS or insulin resistance. It is not. Inositol hexanicotinate, also called inositol nicotinate, has been used more often in products aimed at circulation support, especially in older discussions around blood flow and Raynaud-type symptoms.

It also should not be confused with standard niacin itself. The NIH Office of Dietary Supplements notes that niacin refers to vitamin B3 forms such as nicotinic acid and nicotinamide. Inositol hexanicotinate is a related supplement product, but it is not the same thing as plain myo-inositol powder or capsules. (Office of Dietary Supplements)
The simple answer is this: inositol hexanicotinate is a niacin-related compound that includes inositol, but it is not the same as myo-inositol and should not be treated as an interchangeable PCOS or fertility supplement. If your goal is ovarian support or insulin signaling support, check the label carefully and make sure you are buying myo-inositol, not inositol hexanicotinate. (WebMD)
