We are now up to the letter I in our second pass through the A to Z Dog Food Ingredient series. Today’s dog food ingredient is Inositol.


What is Inositol?

Inositol is a vitamin-like substance. It is found in many plants and animals. Because dogs can produce this internally by breaking down sugars their bodies do not need to rely on dietary intake to provide daily requirements. Thus, Inositol is not considered an essential dietary vitamin.


Common names for Inositol

The most common names for Inositol include Vitamin B-8 Myo-Inositol, and Lipositol.


Why is Inositol in Dog Food?

Inositol aids in the utilization of glycogen (for energy) via the oxidation of fats in the body. Inositol acts as an activator of the ATP mechanisms which are the source of energy to muscles. It also affects neurotransmitters, which are chemicals that transmit nerve impulses.


Is Inositol Commonly Used in Dog Food?

Inositol is a fairly common ingredient. It is included in almost 10% of all dog foods.

Inositol deficiency can lead to diabetes mellitus, gallbladder disease, muscular pain and malfunction, and liver disease.


There are no serious side effects related to inositol, even with high doses, for normally healthy bodies.

Although not considered an essential vitamin, Inositol is an important component of proper nutrition. Feeding your pet a balanced and varied diet that includes named meats, fruits and vegetables, and liver is the best way to ensure your pet has enough in their diet. That said, Inositol is a healthy ingredient and gets the SlimDoggy Happy face.


Miscellaneous facts about Inositol

Some laboratory studies indicate that inositol shows potential for stopping the growth of cancer cells. A recent study published in “International Journal of Molecular Sciences”, December 2013, reported that inositol hexaphosphate from rice bran killed colorectal cancer cells.


A human study published in the “Journal of Experimental and Clinical Cancer Research”, 2010, found that a combination of inositol and inositol hexaphosphate helped relieve side effects experienced by women receiving chemotherapy for breast cancer.
