What Is Inositol?

Inositol is a kind of sugar that affects both the body’s insulin reaction and a number of hormonal agents related to mood and cognition. It’s frequently described as vitamin B8, however it is not really a vitamin. Inositol likewise has antioxidant properties that combat the harmful impacts of totally free radicals in the brain, circulatory system, and other body tissues.

Inositol is discovered naturally in cantaloupe, citrus fruit, and lots of fiber-rich foods (such as beans, brown rice, corn, sesame seeds, and wheat bran). It is also offered in supplement type and used as a complementary treatment to deal with a vast array of medical conditions, consisting of metabolic and state of mind conditions.

D-chiro-inositol, inositol hexaphosphate (often described as “IP6”), and the compound myo-inositol are the most widely used inositol supplements. They are normally considered safe if taken appropriately.

This short article goes over the prospective health benefits and uses of inositol. It also covers dosage, preparation, potential side effects, and interactions you should consider prior to taking this compound.

Typically Referred to as

  • Inositol
  • D-chiro-inositol
  • Inositol hexaphosphate (or “IP6”)
  • Myo-inositol [1]


Inositol is a word that collectively refers to particles with a comparable structure, a collection of 9 stereoisomers. While the term ‘inositol’ is used typically with dietary supplements, it typically describes a specific stereoisomer called myo-inositol. Inositols are pseudovitamin compounds that are wrongly stated to belong to the B-complex household, and are found in a lot of foods however in highest levels in whole grains and citrus fruits.

Myo-inositol reveals the most promise as a dietary supplement for promoting female fertility, bring back insulin level of sensitivity in circumstances of resistance (type II diabetes and polycystic ovarian syndrome being the most well investigated), and for lowering anxiety also. Due to the mixed advantages to insulin resistance and fertility, myo-inositol is considered a great treatment for PCOS in women.

It likewise holds some promise as an anti-depressant (although not as outstanding as its anxiolytic and anti-panic effects) and versus some other conditions related to anxiety such as panic attack and binge consuming. It is reasonably ineffective for schizophrenia and autism, and has actually stopped working in treating PTSD despite its anti-panic impacts.

In part because of its benefits to fertility and PCOS, along with the anxiolytic effects possibly assisting signs of PMS (dysphoria and anxiety mainly), myo-inositol is often referred to as a general female health supplement. At times, the anti-depressant effects associated with this supplement seem to only operate in females with males having no advantage.

It is an extremely safe supplement to consume, and all side-effects related to myo-inositol are simply moderate gastrointestinal distress from high doses. High dosages (generally in the 12-18g variety) are needed for any neurological impacts while lower dosages (2-4g) suffice for fertility and insulin sensitizing effects. [2]


Inositol can stimulate glucose uptake in skeletal muscle cells which allows the decline in blood sugar levels. This effect is later on viewed as a decrease in urine glucose concentration and suggests a decline in high blood sugar level levels.

In PCOS, the administration of inositol has actually produced the remission of signs along with a reduction in male hormone secretion9, a regulation of the cholesterol level, and a more effective fat breakdown which permit to a substantial reduction on body mass and appetite.

In the cases of infertility, inositol has been proven to increase sperm count and motility, in addition to increase the total quality of oocytes and embryos.

In the brain, inositol has been revealed to produce an increase in serotonin receptor level of sensitivity. This activity produces a boost in GABA release. A few of the impacts observed in the brain produced a relief in symptoms of anxiety and obsessive-compulsive conditions. In high doses, it has actually been revealed to even decrease panic attacks.

In cancer research study, inositol has actually gotten interest as it can act as an antioxidant, anti-inflammatory and it appears to boost immune properties.

System of action

The mechanism of action of inositol in brain disorders is not totally understood but it is believed that it may be associated with neurotransmitter synthesis and it is a precursor to the phosphatidylinositol cycle. The change that happens in the cycle simulates when the postsynaptic receptor is activated however without activating the receptor. This activity provokes a phony activation which regulated the activity of monoamines and other neurotransmitters.

Reports have shown that insulin resistance plays a crucial function in the scientific advancement of PCOS. The existence of hyperinsulinemia can induce an excess in androgen production by promoting ovaries to produce androgens and by minimizing the sex hormone binding globulin serum levels. Among the systems of insulin deficiency is thought to be connected to a deficiency in inositol in the inositolphosphoglycans. The administration of inositol permits it to act as a direct messenger of the insulin signaling and improves glucose tissue uptake. This mechanism is extrapolated to its functions in diabetes treatment, metabolic syndrome, and weight-loss.

In cancer, the mechanism of action of inositol is not fully comprehended. It is assumed that the administration of inositol increases the level of lower-phosphate inositol phosphates why can affect cycle regulation, growth, and distinction of malignant cells. On the other hand, the formation of inositol hexaphosphate after administration of inositol presents antioxidant attributes by the chelation of ferric ions and suppression of hydroxyl radicals.


Inositol is absorbed from the small intestine. In clients with inositol shortage, the optimum plasma concentration after oral administration of inositol is registered to be of 4 hours.19 Inositol is taken up by the tissues via sodium-dependent inositol co-transporter which likewise mediates glucose uptake.20 Oral ingestion of inositol is signed up to create a maximal plasma concentration of 36-45 mcg.

Volume of distribution

The pharmacokinetic profile of inositol was studied in preterm infants and the approximated volume of circulation was reported to be 0.5115 L/kg.

Protein binding

It is believed that inositol can be found bound to plasma proteins.


It is believed that inositol is metabolized to phosphoinositol and then transformed to phosphatylinositol-4,5- biphosphate which is a precursor of the second-messenger particles.25 Inositol can be changed to D-chiro-inositol through the actions of an epimerase. The normal adjustments to inositol structure appear to be in between all the different isomers.

6 Things to Understand About Taking Inositol for PCOS

Polycystic ovary syndrome, or PCOS, is caused by a hormonal agent imbalance. It can result in associated health problems, including diabetes and infertility. Treatment with vitamin-like substances called inositols has shown promising results.

Continue reading to find out more about inositol supplements and how they may assist people with PCOS control blood sugar level and increase the possibilities of conceiving.

Inositol Improves Insulin Resistance

Inositols are a kind of sugar the body makes. They assist balance chemicals that control your blood sugar and fertility. They likewise affect your metabolic process, the procedure of turning the food you eat into energy.

Many individuals with PCOS are insulin resistant. Their bodies make insulin but aren’t able to use it successfully. This increases the threat of diabetes, infertility, obesity, and high cholesterol.

Inositols make molecules involved in the body’s action to insulin. Scientists say inositols might become part of the body’s messaging system when the typical insulin signaling system fails.

You Can Get Inositols From Food and Supplements

You can get inositols by consuming healthy foods such as:.

  • Fruits: Cantaloupe, grapefruit, other citrus fruits
  • Beans: Lima, navy
  • Grains: Wild rice, whole wheat
  • Nuts: Almonds, walnuts

You can also buy inositol food supplements, pills, or powders you mix with water. Inositol supplements are generally well-tolerated.

Inositols MI and DCI Are Beneficial For PCOS

There are nine types of inositol, however the two that have the biggest impact on PCOS are myo-inositol (MI) and D-chiro-inositol (DCI).

Typically, MI is transformed to DCI. But researchers believe individuals with PCOS may be less able to transform MI into DCI. Lower levels of DCI increase the danger of insulin resistance and high blood glucose.

High MI to DCI Ratio May Add To PCOS

In healthy females, most body tissue has an MI to DCI ratio of around 40 to 1. This ratio is much greater in individuals with PCOS.

Combined therapy with MI and DCI is more reliable than taking either inositol alone. Particularly, research study reveals a 40:1 MI/DCI ratio is best for rebooting ovulation in people with PCOS.

MI and DCI in a 40:1 ratio may be more efficient than Metformin. One research study found individuals with PCOS who took the 40:1 MI/DCI supplement had substantially better ovulation and pregnancy rates (46.7% vs. 11.2%) than those who did not take the supplement.

However, some food supplement business continue to offer supplements with differing MI/DCI ratios. One evaluation found that the MI to DCI ratio in PCOS items can range from as little as.04-to-1 to as high as 104-to-1.

Some supplements consist of just DCI, while others consist of additional compounds such as vitamins and artificial sugars. There’s no evidence to reveal these components assist.

The Right MI to DCI Ratio Improves Fertility

PCOS is a typical cause of infertility. As much as 80% of people with PCOS experience infertility obstacles.

Individuals with PCOS have an imbalance of MI to DCI in their ovaries. This can impact their:.

Periods: Individuals with PCOS can have irregular durations or no periods at all. Treatment with inositols has actually been revealed to assist enhance insulin level of sensitivity and decrease male hormonal agent levels in females with PCOS. This assists bring back periods.

Ovulation: People with PCOS might not ovulate on a monthly basis or at all. Scientists have actually linked this to having insufficient MI and excessive DCI in the ovaries.

Egg quality: Women with PCOS have been revealed to produce less fully grown eggs than females without the disorder.12 Researchers have linked this to having too little MI in the follicular fluid, which surrounds the eggs within the ovaries.

Eggs can’t grow unless there is a high level of MI in the follicular fluid.5 In healthy women, the MI to DCI ratio in this fluid is about 100 to 1. In sterile women with PCOS, the typical ratio of MI to DCI in this fluid is 0.2 to 1.13.

Inositols can assist bring back ovulation and improve oocyte (immature egg) quality. But researchers alert taking the proper solution is vital because high doses of DCI adversely impact oocytes and avoid the body from soaking up MI.

MI Is Utilized Reward Gestational Diabetes

People with PCOS have an increased threat of gestational diabetes (GD), which is diabetes that develops in pregnancy. A study released in 2019 concluded that people with PCOS have a two-fold greater danger of establishing GD than those without PCOS.

Taking MI supplements decreases blood sugar level levels and GD threat in individuals with PCOS. A 2012 research study found GD was less common in pregnant females with PCOS who took MI than those who did not take the supplement. [4]


May Have Mental Health Benefits

Inositol may assist balance crucial chemicals in your brain, including those thought to impact your state of mind, such as serotonin and dopamine.

Remarkably, scientists have discovered that some individuals with depression, stress and anxiety and compulsive disorders have lower levels of inositol in their brain.

Though more research is required, a number of studies recommend that inositol has the prospective to be an alternative treatment for mental health conditions. It also appears to have fewer negative effects than conventional medications.

Panic Disorder

While research is still limited, inositol supplements may be handy for dealing with panic attack, a serious kind of stress and anxiety.

Those with panic disorder experience regular anxiety attack, which are sudden feelings of extreme fear. Symptoms include rapid heartbeat, shortness of breath, dizziness, sweating and a tingling or numb feeling in the hands.

In one study, 20 people with panic attack took either an 18-gram inositol supplement or a common stress and anxiety medication every day for 1 month. Those taking inositol had less panic attacks weekly, compared to individuals taking the stress and anxiety medication.

Likewise, in a 4-week study, people experienced less and less severe panic attacks when taking 12 grams of inositol each day.


Inositol may enhance symptoms of anxiety, however research has actually had mixed outcomes.

For instance, an early research study showed that taking a 12-gram inositol supplement every day for 4 weeks improved signs in individuals with anxiety.

In contrast, subsequent research studies were unable to reveal any substantial benefits.

In general, there is insufficient proof yet to state whether inositol has a true impact on anxiety.

Bipolar Disorder

Just like the other psychological health conditions, research study on the effects of inositol and bipolar illness is restricted. However, the outcomes of preliminary studies seem appealing.

For example, a little research study in kids with bipolar spectrum disorders showed minimized signs of mania and anxiety when a combination of 3 grams of omega-3 fatty acids and approximately 2 grams of inositol were taken daily for 12 weeks.

In addition, research studies suggest that 3– 6 grams of inositol taken daily might help reduce symptoms of psoriasis brought on by lithium, a typical medication utilized to deal with bipolar disorder.


Though more research is required, inositol shows potential as an alternative treatment option for mental health conditions, including panic attack, anxiety and bipolar affective disorder.

Might Assist Control Metabolic Syndrome Risk Elements

Medical research studies suggest inositol supplements may be beneficial for those with metabolic syndrome.

Metabolic syndrome is a group of conditions that raise your threat of chronic illness, consisting of heart problem and type 2 diabetes.

Particularly, five conditions are related to metabolic syndrome:.

  • Excess fat in the stomach area
  • High levels of triglycerides in the blood
  • Low “excellent” HDL cholesterol levels
  • Hypertension
  • High blood glucose

In a year-long scientific research study in 80 women with metabolic syndrome, 2 grams of inositol taken twice daily decreased blood triglyceride levels by an average 34% and overall cholesterol by 22%. Improvements in blood pressure and blood glucose were also seen.

Exceptionally, 20% of the ladies taking inositol supplements no longer fulfilled the criteria for metabolic syndrome by the end of the research study.


Inositol may help manage metabolic threat aspects by assisting lower blood triglyceride levels, blood pressure and blood sugar level. It might also improve cholesterol levels.

May Prevent Diabetes During Pregnancy

Some women experience high blood sugar level during pregnancy. This condition is called gestational diabetes (GDM) and complicates approximately 10% of pregnancies in the US every year.

In animal studies, inositol has actually been directly connected to the function of insulin, a hormone that manages blood sugar levels.

Only a limited number of research studies are available on the supplement and GDM in human beings. Nevertheless, some recommend that a combination of 4 grams of myo-inositol and 400 mcg of folic acid may be valuable in preventing GDM when taken daily throughout pregnancy.

However, more research is needed, as other research studies have actually not shown the very same results.


Inositol may help avoid high blood glucose levels during pregnancy when taken in mix with folic acid, however more studies are needed to confirm this result.

Other Possible Advantages

Inositol has been studied as a potential treatment choice for many conditions.

Besides those currently pointed out, research suggests inositol might be useful in the list below conditions:.

Respiratory distress syndrome: In preterm babies, inositol appears to be helpful for treating breathing issues from underdeveloped lungs.

Type 2 diabetes: A preliminary study recommends that inositol and folic acid taken daily for 6 months may help blood sugar level control in people with type 2 diabetes.

Obsessive-compulsive condition (OCD): A little study recommends that 18 grams of inositol taken daily for 6 weeks might lower symptoms of OCD.


Inositol is a possible treatment choice for preterm babies with respiratory distress syndrome. It might also help blood sugar level control in individuals with type 2 diabetes and might lower signs of obsessive-compulsive disorder. [5]


Chemically inositols are isomers of hexahydroxy-cyclohexanes. Among the nine possible geometrical isomers of inositol, seven are optically inactive or “meso,” and the staying 2 form a chiral pair. The planar structures of the different isomers of this compound exist in Figure 1. The particle of MI has one axial and five equatorial hydroxyl groups. The axial hydroxyl group at position 2 is most stable to hydrolysis.

L-myo-inositol-1-phosphate synthase (MIPS) catalyzes the first step in the biosynthesis of all myo-inositol-containing substances (Seelan et al., 2009). It converts glucose-6-phosphate to myo-inositol-1-phosphate (MIP). The phosphate moiety in MIP is subsequently gotten rid of by myo-inositol-1-phosphatase (IMPase) to produce free MI (Majumder and Biswas, 2006).

In addition, this compound might also be produced by cyclic synthesis (Agranoff et al., 1958; Paulus and Kennedy, 1960) and the hydrolysis of phosphatidylinositol. Although MIP is the intermediate common to both paths, 2 various types of compound are produced, the L-form by the artificial pathway and the D-form by the cyclic path (Parthasarathy and Eisenberg, 1986). Nevertheless, both the isomers are catalyzed by IMPase (Eisesnberg, 1967), which produces MI. [6]

Sources of Inositol

As formerly mentioned, inositol is found in naturally in certain foods but in relatively low levels. The highest levels of inositol are typically discovered in entire grains and citrus fruits.

Typical Food Sources.

  • Oranges
  • Grapefruit
  • Dried prunes
  • Terrific northern beans
  • Navy beans
  • Stone ground wheat
  • Bran flakes

Inositol is often marketed as vitamin B8– however, so is a substance called AMP (adenosine monophosphate). Make sure to try to find supplements particularly identified inositol or myo-inositol.

Do I Need A Inositol Supplement?

Inositol is a psuedovitamin and not critical for human function. However, as seen in long-lasting lithium treatment, inositol exhaustion can lead to psoriasis. Given the appealing results of scientific trials for conditions varying from fertility problems and metabolic conditions to behavioral and neurological conditions, inositol supplementation ought to be offered strong factor to consider for anyone fighting with these conditions.

How Much Inositol Do I Required?

To experience maximum take advantage of inositol, the dosage will differ depending on both the objectives of supplementation and the type of inositol taken. The below-recommended amounts are for powdered inositol supplements.

For the treatment of female-specific conditions such as PCOS or PMDD, medically effective does vary from 200-4000mg day-to-day. The more extreme the condition, the greater the suggested dosage of inositol.

For behavioral and neurological conditions, healing doses range from 6-18g daily.

If inositol soft gel supplements are used, approximately 30% of the suggested powdered dosage is considered equivalent.

What are inositol side effects?

Negative effects associated with inositol supplementation are rare, and typically restricted to mild stomach upset in unusually high doses. Opposite impacts reported may consist of sensation “wired”, nervous, tense, insomnia, yellow urine, and palpitations. Research has not yet assessed the safety and efficiency of inositol during pregnancy, so do not utilize while pregnant unless advised by a doctor.

Are There Any Medications or Supplements I Should Not Take With Inositol?

There is currently no adequate evidence that inositol supplements cause unfavorable interactions with any other drugs and supplements. However, phytic acid– the type of inositol found in foods– may disrupt the absorption of minerals, especially calcium, zinc, and iron.

Should you be supplementing with Inositol?

People with PCOS, type 2 diabetes, depressive and/or stress and anxiety conditions will almost certainly benefit from an inositol supplement. Research study has shown that ladies gain from inositol supplements for health conditions as moderate as PMS or as severe as PCOS, in addition to the conditions pointed out in the advantages section. Male, nevertheless, may only see advantages when supplementing for the specific conditions pointed out in the advantages section. [7]


The following dosages have been studied in clinical research study:.

By mouth:

  • For panic attack: 12 to 18 grams per day.
  • For obsessive-compulsive disorder: inositol 18 grams per day.
  • For dealing with symptoms related to polycystic ovary syndrome: D-chiro-inositol 1200 mg per day.
  • For dealing with lithium-related psoriasis: 6 grams daily. [8]

Special Precautions and Cautions

Pregnancy: Inositol is perhaps safe when taken by mouth, short-term. Doses of as much as 4000 mg of myo-inositol day-to-day have been utilized with obvious security.

Breast-feeding: There isn’t adequate trustworthy information to understand if inositol is safe to use when breast-feeding. Remain on the safe side and avoid usage.

Children: Inositol is perhaps safe when taken by mouth for as much as 12 weeks in kids ages 5-12 years old. [9]


Inositol is a really appealing treatment for depression and panic attack. It is promising for bipolar illness, stress and anxiety, fixation, obsession, eating disorders, hostility, sadness, tension and fatigue. It is rather safe. Adjunctive usage may not benefit however will not hurt. People with bipolar disorder must work out greater care. [10]
