Obsessive-compulsive disorder, or OCD, is an often incapacitating condition that affects millions of people worldwide. OCD is characterized by uncontrollable, recurring, and/or unreasonable thoughts and behaviors, which can significantly affect quality of life. [1] Selective serotonin reuptake inhibitors, or SSRIs, are often used to treat OCD, yet these medications often benefit just 40-60% of patients. Additionally, SSRIs are associated with a variety of unwanted side effects. [1, 9] When seeking alternative or complementary therapies for OCD, it is essential to consider inositol supplementation, which research shows may be an effective solution.

The Natural Communication Aid

Inositol is a simple dietary polyol, or sugar alcohol, and an isomer of glucose. We consume inositol naturally in our diets; it is found in grains, beans, nuts, fruits, and animal organ meats. [2, 4, 5, 9] In the body, inositol is found in cell membranes as inositol phospholipids, and is especially important in the brain and for helping cell communication, or signaling. Inositol serves as a precursor for the second messenger system. [2, 4, 5, 6, 8, 9]

When a signal reaches a cell, it is passed from surface proteins and receptor complexes to molecules called second messengers. These second messengers pass on the signal from the cell surface to molecules in the cytosol and/or nucleus. This not only relays the signal, but also helps to amplify its strength. [5, 7]

As a precursor for this second messenger system, inositol is used to make phosphoinositides, or inositol triphosphate and diacylglycerol. [5, 6, 7, 8] These are the second messengers on the cell membrane. Inositol helps with the maintenance and effectiveness of cell signaling. It can also alter the sensitivity of receptors and control signaling proteins, among other cell activities. [6, 7]

Inositol’s functions in cell communication is important because this second messenger system is associated with neurotransmitter pathways and receptors, including dopamine, norepinephrine, serotonin, and glutamate. Inositol may modulate the interaction between neurotransmitters, drugs, receptors, and signaling proteins. [3, 6] Inositol may also reverse desensitization of serotonin receptors, a common effect of SSRIs. [9]

Efficacy in OCD

Although the exact mechanisms are yet to be understood, inositol supplementation has been shown to be effective for patients with OCD, due to its role in modulating neurotransmitter signaling and pathways. [1, 2, 4, 6, 9] Inositol has been shown to reduce anxiety and acute stress. [3, 8] In addition to being therapeutic for OCD, inositol may also be beneficial for people with depression, panic disorders, and bipolar depression. [3, 4, 6, 8, 9, 10]

In summary, as an essential component in the second messenger system, inositol helps enhance cell communication and neurotransmitter pathways, and can be efficacious in addressing OCD. Due to its efficacy, tolerability, and lack of side effects, inositol may be appealing to many people seeking alternative or complementary therapies for this often disabling condition.

“Educating Sanesco’s clients is the culmination of a life’s work.” Beginning when she left the hospital environment to manage a functional laboratory, Genova Diagnostics (formerly Great Smokies Laboratories) in 1987, Dr. Connie Shoemaker has continued to increase her knowledge of herbs and biochemistry as a journey of love. With her bachelor’s in science from Western Carolina University, she had worked in hospital laboratories for the first twelve years of her career. Then, personal health challenges led her to discover a new approach to her health and a determination to share it with others. In 1991, she began teaching and educating innovative practitioners in the U.S. and internationally as a manager of marketing, sales, and customer service.

The addition of her Doctor of Naturopathy degree to her existing knowledge base expanded her knowledge and her respect for a more natural approach to healing through balance. At Sanesco, she initially served to oversee technical development of products and services.

Now, she educates Sanesco’s clients on application of the CSM™ model for their specific patients and how to integrate the CSM™ model with other modalities they offer in their practice. In her personal life, Connie educates private clients on various health topics.
