Inositol (or myo-inositol) is a B-vitamin-like molecule often used to help regulate blood sugar, manage polycystic ovarian syndrome (PCOS), and alleviate the symptoms of mood disorders such as low mood or anxiousness. Inositol is essential to multiple brain signaling systems, as it helps improve the sensitivity of various receptors, therefore enhancing the delivery of messages from a variety of hormones and neurotransmitters (brain messenger-molecules). Essentially, this helps hormones such as insulin and neurotransmitters such as serotonin and dopamine work more effectively.

Research suggests that high doses of inositol can address the symptoms of behavioural and compulsive disorders, particularly those related to mood imbalances. Recent research also supports a role for lower doses of inositol in cellular defense and normal cell growth and differentiation, especially in combination with I-P-6 (inositol hexaphosphate or phytate).

Those suffering with poor regulation of blood sugar, polycystic ovarian syndrome (PCOS), or mood disorders may benefit from AOR Inositol. It can also be used as a preventive, for people concerned with healthy cellular growth and differentiation.

AOR Advantage

Inositol has the ability to support a healthy mood balance and normal cellular growth and differentiation.

In one of the first clinical trials, researchers assembled 39 people with major depression or bipolar depression, who quit taking their antidepressant medications three days to a week before the trial began. For the next four weeks, sufferers took either twelve grams of inositol powder a day (two teaspoons, twice daily, in juice) or a placebo powder (glucose).

Hamilton depression Rating Scale (HAM-D) scores fell during the first two weeks in both groups. An initial response even on a dummy substance is often seen early on in clinical trials for depression, because of the power of hope actually affects brain function. But while those assigned to take the stand-in powder remained stuck at this plateau from then on, people taking inositol powder experienced an additional 20.5% drop in their depression scores by the end of the trial. Plus, inositol was not associated with manic episodes in the victims of bipolar depression – an important result, since many treatments for this disorder push its victims into the opposite pole, with disastrous consequences.

Inositol had loosened the jaws of the black dog of depression. And this was just the beginning.

Bipolar Depression

Buoyed by the success of patients with bipolar affective disorder depression who had taken inositol in the first trial, scientists next initiated a trial using only victims of this specific disease. In this trial, 24 men and women suffering with bipolar depression were randomly placed into groups supplementing with either 12 grams of inositol powder or an equal amount of glucose powder as a placebo for six weeks. All patients kept up their standard medications throughout the trial.

At the end of the trial, half of the people taking the inositol powder supplement enjoyed a 50% or greater relief of their depression as measured on the HAM-D; likewise on the Clinical Global Improvement (CGI) scale, the same inositol supplementers were seen to be “much” or “very much” improved. By contrast, only 30% of those taking the placebo experienced such benefits. Similarly, twice as many people supplementing with the inositol powder improved by 50% or more on the Montgomery-Asberg Depression Rating Scale (MADRS) as people stuck with the placebo.

The numbers did not meet the statisticians’ criteria for “significance;” however, they were so consistent that the researchers concluded that this was likely just the result of the small number of participants, and perhaps reflected the need for a more precise way of evaluating this specific class of depression. The effects the physicians saw in their patients lives left them confident that the power of inositol in victims of bipolar depression is real.

Eating Disorders

Twenty-four bulimic or binge eating patients took part in a double-blind, placebo-controlled crossover trial in which, after an initial run-in period, they took either 18 grams of inositol powder or a sugar placebo for six weeks each. They then switched over to taking the substance, which they had not taken in the previous period, again for six weeks. No one knew which sweet powder a given person was taking at a given time.

When the “blinds” came off at the end of the study, it was revealed that these eating disorder victims experienced a 45% alleviation in their Visual Analog Scale of severity of binge eating (VAS-B) scores, along with a 30% improvement on their CGI scores, a 24% better Eating Disorder Inventory (EDI) result, and a 28% healthier Eating Attitude Test (EAT) result while supplementing with inositol powder. While patients were also slightly better off during their time on the sugar powder than they had been before the trial began, the differences were the weak effects to be expected from a mild “placebo effect:” just a 15.5% shift on the VAS-B, no improvement on the CGI, a 9.9% blip on the EDI, and an 18.6% change on the EAT. None of the changes associated with the placebo period was strong enough to be statistically significant, unlike the potentially life-saving effects seen with inositol.

Panic Disorder

In yet another study, 21 people with panic disorder who wanted to escape the side effects of their drug therapies completed a double-blind trial of inositol powder. All stopped taking their standard medications one week before starting the study; after a one week run-in period, the participants supplemented with one of two sweet powders – either inositol or a placebo powder (6 grams of glucose or mannitol, twice daily) – for four weeks, after which they switched over to the alternative powder for the remaining four weeks. Their initial condition, and their progress, was quantified using the HAM-D, along with the Hamilton Rating Scale for Anxiety (HAM-A) and a panic score that was based on the number of panic attacks a person suffered weekly and the severity and number of symptoms associated with each attack.

Every outcome was improved while people were supplementing with inositol powder. Inositol users suffered over 40% fewer panic attacks per week than they did when only taking a sugar. Their panic scores were only a third as high as they were during their time on a placebo, and their phobia scores were more than a third lower. And while the results did not cross the threshold of statistical significance, raw HAM-D and HAM-S scores also fell more in the inositol supplementation period than when they were swallowing the powdered sweeteners. Clearly, inositol powder lifted much of the desperate burden of nameless anxiety from the shoulders of people who took it.

In a second trial, researchers pitted inositol head-to-head against fluvoxamine (Luvox®) in a double-blind, placebo-controlled, random-order crossover study. For one month, twenty victims of panic disorder took either a dummy Luvox® tablet and real inositol powder (18 grams), or real Luvox® and powdered sugar as a stand-in for inositol; then, they were switched to the opposite combination for a second month.

It was exciting enough when the study revealed that by most criteria, people got just as much relief from panic by using inositol supplements as they did from taking the drug: HAM-A, phobia, and CGI scores all improved by about the same amount in both groups. This alone is enough to merit the attention of panic disorder victims and their physicians – especially when you consider how much more often drug users traded symptomatic relief for side effects such as nausea (twice as common) and tiredness (nine times more likely).

But in fact, the study revealed that inositol is actually more effective than fluvoxamine in reducing the number of panic attacks suffered, cutting weekly attacks by 57% while the drug only reduced them by 41%!

Obsessive-Compulsive Disorder (OCD)

Inositol powder has also been documented to relieve the maddening fixations of OCD. In a double-blind, placebo-controlled crossover study, thirteen obsessive-compulsive men and women completed a cycle of taking 18 grams of either inositol powder or a sugar placebo each day for six weeks, followed by using the other treatment for the next six weeks.

Even on a preliminary analysis, people experienced 12.5% greater relief of obsessive symptoms while taking inositol powder, as measured on the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), than when taking the placebo. Even this was a statistically significant difference. But the full power of inositol was only revealed when the researchers re-analyzed the data after excluding the patients who had initially been referred from a clinic’s “resistant” patients only, looking instead at patients from clinics whose patients had a wider spectrum of patients. Looking at these “mixed” obsessive-compulse patients, the improvement experienced from taking inositol powder was nearly double that reported for the placebo period (181% as great an improvement).

Important Notes About Inositol Powder

In all of the placebo-controlled trials, safety was monitored using various blood and urine tests for things like liver enzymes, blood cell counts, and indicators of kidney function; no significant changes were noted, nor was there any difference between the people taking real inositol powder and those just swallowing sugar. Side effects were all minor, and were just as common in the placebo group as in the people taking inositol. As is common in psychological disturbances responsive to SSRI drugs, there was a high dropout rate in the trials – but it was equally spread out among groups taking inositol and groups fed sugars. In every respect assayed, the studies found high-dose inositol to be an extremely safe, well-tolerated supplement.
