- \n
- It\u2019s found naturally in the human body<\/strong>, specifically in our brain, tissues, and cell membranes.<\/li>\n\n\n\n
- Our kidneys make about 2 grams of inositol<\/strong> from glucose (which is converted from the carbohydrates we eat).<\/li>\n\n\n\n
- It\u2019s found in high quantities in meat, fruits (especially citrus), vegetables, grains, nuts, and seeds<\/strong>. So, it\u2019s important to eat a healthy diet and not stuff yourself with junk food!<\/li>\n<\/ul>\n\n\n\n
Inositol was formerly known as vitamin B8<\/strong>, but it has since been reclassified as it\u2019s not really a true vitamin. It\u2019s also not considered an essential nutrient, since the body makes it from glucose synthesis. By definition, essential nutrients are those that are needed by the body, but we either can\u2019t make it or can\u2019t make enough<\/em> of it. So, it must be obtained via diet (or supplements) to meet the body\u2019s needs.<\/p>\n\n\n\n

<\/figure>\n\n\n\nWhat is myo inositol?<\/h2>\n\n\n\n
Inositol has 9 forms or isomers. The most common and abundant form is myo inositol <\/strong>(or myo-inositol). Myo inositol is so abundant that whenever you read or hear the word inositol, it\u2019s actually myo inositol that\u2019s being referred to. When required, the human body can convert myo-inositol to its other isomers.<\/p>\n\n\n\n
These are the other inositol isomers:<\/strong><\/p>\n\n\n\n
- \n
- D-chiro-inositol (second most abundant form)<\/li>\n\n\n\n
- L-chiro-inositol<\/li>\n\n\n\n
- Scyllo-inositol<\/li>\n\n\n\n
- Muco-inositol<\/li>\n\n\n\n
- Neo-inositol<\/li>\n\n\n\n
- Allo-inositol<\/li>\n\n\n\n
- Epi-inositol<\/li>\n\n\n\n
- Cis-inositol<\/li>\n<\/ol>\n\n\n\n
Unless otherwise specified, every time you read the word inositol in this post (or in our blog, for that matter), know that we\u2019re referring to myo-inositol<\/a>.<\/strong><\/p>\n\n\n\n
What is d-chiro-inositol?<\/h2>\n\n\n\n
D-chiro-inositol is another inositol isomer. While it doesn\u2019t occur in large quantities in nature, it\u2019s the second most abundant type of inositol, next to myo inositol. As mentioned above, our bodies can convert myo inositol to d-chiro-inositol, if necessary.<\/p>\n\n\n\n
The body\u2019s normal ratio of myo inositol to d-chiro-inositol is 40:1. Most inositol blends (supplements) offer a combination of myo-inositol and d-chiro-inositol in this ratio.<\/p>\n\n\n\n
![\"Why](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/benefici-utilizzi-e-dosaggio-dell-inositolo-in-polvere-02.jpg\")
<\/figure>\n\n\n\nWhy inositol powder?<\/h2>\n\n\n\n
Inositol can be purchased in powder, tablet or capsule form. While some brands offer both types, we believe inositol powder is a far better option. But don\u2019t take our word for it, check out the pros and cons of each format so you can decide for yourself!<\/p>\n\n\n\n
Inositol powder<\/h3>\n\n\n\n
Scooping out your daily inositol dose may sound like a chore, but it\u2019s actually the more practical option. As you\u2019ll learn later on in this article, inositol dosage varies from one malady to another. The powder form makes it easy to adjust the dosage<\/strong>.<\/p>\n\n\n\n
For example, if the manufacturer says 1 scoop is 1 serving, then it\u2019s easy to figure out how many scoop(s) you need for your specific needs. To take half a serving, just take half a scoop. To double or triple your serving, just double or triple your scoop! Easy!<\/p>\n\n\n\n
Also, inositol powder is very easy to take. You simply need to mix it with water or some other liquid beverage<\/strong> and then drink it. Some brands claim to have a neutral tasting inositol powder, however, inositol actually tastes a bit sweet. So, it\u2019s great for sweetening your morning coffee or tea<\/strong>.<\/p>\n\n\n\n
Inositol tablet or capsule<\/h3>\n\n\n\n
Inositol is also sold in tablet or capsule format. It\u2019s really the more convenient option <\/strong>because you can just pop one or two pills in your mouth and chase it down with water. However, adjusting the dosage isn\u2019t as easy<\/strong>.<\/p>\n\n\n\n
For example, some brands will require you to take 4 pills daily to meet the required serving size. This means if you were to double or even triple the serving size<\/strong> (yes, inositol is safe even in large doses \u2013 more on this below), you\u2019ll be taking 8 or even 12 tablets in a single day<\/strong>! I don\u2019t know about you, but that\u2019s simply too many for me!<\/p>\n\n\n\n
Capsules are easy enough to break open to get to the powder inside. But why go through all the hassle? Just get inositol powder in the first place!<\/p>\n\n\n\n
![\"Health](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/3-28.jpg\")
<\/figure>\n\n\n\nWhat are the health benefits of inositol?<\/h2>\n\n\n\n
Inositol has so many health benefits, we will be dividing this section into 3 parts \u2013 health benefits for everyone, health benefits for the ladies, and health benefits for men.<\/p>\n\n\n\n
8 health benefits for both men and women<\/h3>\n\n\n\n
1. Inositol promotes insulin sensitivity<\/h4>\n\n\n\n
Insulin is an important hormone produced by the pancreas. It regulates blood sugar levels in the body and it also plays a role in fat and protein metabolism. Poor insulin sensitivity, a.k.a. insulin resistance, increases the risk of type 2 diabetes, metabolic syndrome, PCOS, heart disease, and more<\/strong>.<\/p>\n\n\n\n
So, how exactly does inositol improve insulin sensitivity? To answer this question, let\u2019s look at the relationship between carbs and insulin:<\/p>\n\n\n\n
In addition to vitamins and minerals, the foods we eat also give us fat, protein, and carbohydrates. Carbs are our body\u2019s main source of energy<\/strong>. Once carbs reach the gut, they are broken down into glucose or blood sugar. Once the sugar enters the bloodstream, your blood sugar level will naturally spike. This is then a signal for the pancreas to release insulin into the bloodstream. Insulin\u2019s job is to move the glucose into the cells, where it\u2019s either used for energy or stored as fat<\/strong>. This process allows blood sugar levels to go back down to normal.<\/p>\n\n\n\n
Now, this is where the problem lies:<\/p>\n\n\n\n
Eating too much carb-heavy foods over a prolonged period can lead to insulin resistance. Remember, more carbs = higher blood sugar levels<\/strong>. This oversupply of carbs will eventually lead to the pancreas going into hyper mode to produce even more insulin. Sooner or later, cells stop responding to insulin. When this happens, you\u2019ll end up having both high blood sugar levels and high insulin levels<\/strong>. If left untreated, this can lead to insulin resistance.<\/p>\n\n\n\n
Fortunately, inositol can help reverse insulin resistance. Several clinical studies support the fact that inositol can reduce blood sugar levels as well as insulin levels<\/strong>, thereby improving insulin sensitivity in both PCOS and non-PCOS patients (1<\/a>, 2<\/a>).<\/p>\n\n\n\n
![\"Inositol](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/4-10.jpg\")
<\/figure>\n\n\n\n2. It reduces LDL cholesterol and total cholesterol levels<\/h4>\n\n\n\n
Cholesterol may have received a bad rap in recent decades, but it\u2019s actually a pretty important nutrient that\u2019s found throughout our cells. That said, there are two types of cholesterol:<\/p>\n\n\n\n
- \n
- Low-density lipoprotein (LDL)<\/strong> \u2013 this is \u201cbad\u201d cholesterol. High LDL levels increase the risk of stroke and heart disease.<\/li>\n\n\n\n
- High density lipoprotein (HDL)<\/strong> \u2013 this is \u201cgood\u201d cholesterol. Raised HDL levels lower the risk of stroke and heart disease.<\/li>\n<\/ul>\n\n\n\n
Together, these two make up your total cholesterol<\/strong>. <\/p>\n\n\n\n
According to a review of 14 randomized controlled trials published in 2018, inositol supplementation led to significantly reduced LDL and total cholesterol levels<\/strong>. Inositol did not affect HDL levels, but it does not detract from the fact that inositol can help reduce your risk of stroke and heart disease (3<\/a>)!<\/p>\n\n\n\n
3. Inositol helps reduce triglyceride levels in the body<\/h4>\n\n\n\n
Just like bad cholesterol, it\u2019s also important to manage your triglyceride as high levels<\/strong> increase your risk of stroke, heart disease, and heart attack<\/strong>. Unfortunately, those with poor insulin sensitivity also have high triglyceride levels. The good thing is that a number of studies point to the fact that inositol has a positive effect on plasma triglycerides<\/strong> (2, 3).<\/p>\n\n\n\n
On a side note, omega 3 fatty acids are also known to help lower triglycerides. Check out this article on the 24 ways omega 3 can help improve your life<\/a><\/strong>!<\/p>\n\n\n\n
![\"Inositol](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/5-6.jpg\")
<\/figure>\n\n\n\n4. Alleviate anxiety, depression and panic disorders<\/h4>\n\n\n\n
According to J. Levine, inositol has therapeutic effects in disorders that respond to SSRI\u2019s<\/a> or selective serotonin reuptake inhibitors<\/strong>. These are antidepressants that are used to treat depression, obsessive compulsive disorder (OCD), panic disorders, and phobias like agoraphobia and social phobia (4<\/a>).<\/p>\n\n\n\n
Here is a summary of Levine\u2019s findings: <\/p>\n\n\n\n
Depression<\/em><\/strong><\/p>\n\n\n\n
28 patients were given 12g of inositol daily. After 4 weeks, their mental conditions showed a marked improvement according to the Hamilton Depression Scale.<\/p>\n\n\n\n
Panic disorder<\/em><\/strong><\/p>\n\n\n\n
21 patients with panic disorder (with or without agoraphobia) were given 12g of inositol daily for 4 weeks. The results were nothing short of amazing! The patients all experienced significantly fewer episodes of panic attacks, and when they did have them, they weren\u2019t as severe as before.<\/p>\n\n\n\n
Obsessive compulsive disorder<\/em><\/strong><\/p>\n\n\n\n
After 6 weeks of taking 18g of inositol daily, 13 patients with OCD experienced a significant improvement in their symptoms.<\/p>\n\n\n\n
According to the same study, inositol did not help improve conditions that do not respond to SSRI\u2019s<\/strong>. These include conditions like Alzheimer\u2019s, schizophrenia, and autism.<\/p>\n\n\n\n
5. Inositol powder shows promise for bipolar disorder <\/h4>\n\n\n\n
We all go through a roller coaster of emotions, but bipolar folks take it to extreme levels. Mood swings vary wildly from extreme highs (mania) to extreme lows (depression), with some stable periods in between. <\/p>\n\n\n\n
A study done on 24 bipolar kids (ages 5-12) with mild to moderate symptoms revealed an interesting outcome. The kids were divided into 3 groups. One group was given inositol, the second group was given omega-3, and the last group was given inositol + omega-3.<\/p>\n\n\n\n
After 12 weeks, the group taking inositol + omega-3 showed the most significant improvement in their bipolar symptoms. <\/strong>This is according to the Young Mania Rating Scale and Children\u2019s Depression Rating Scale (5<\/a>).<\/p>\n\n\n\n
![\"Psoriasis](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/benefici-utilizzi-e-dosaggio-dell-inositolo-in-polvere-06.jpg\")
<\/figure>\n\n\n\n6. Help treat psoriasis caused by lithium<\/h4>\n\n\n\n
Lithium is a mood stabilizer that is often prescribed to bipolar patients. It works as intended, but it does have a number of undesirable side effects, one of which is psoriasis. Psoriasis is an extremely itchy skin condition that show up as raised, scaly patches anywhere on the body.<\/p>\n\n\n\n
Fortunately, switching from lithium to inositol<\/strong> has shown incredible results as evidenced by a case study done on a bipolar patient. Instead of lithium, the patient was prescribed 3g of inositol daily. After 4 years of regular follow ups, the study concluded by saying inositol is very effective for the patient\u2019s bipolar symptoms and psoriasis<\/strong> (6<\/a>).<\/p>\n\n\n\n
7. May help promote weight loss<\/h4>\n\n\n\n
Anyone wanting to lose weight should not look at inositol as a weight loss supplement, because it really isn\u2019t. However, because it\u2019s so effective at promoting insulin sensitivity, one of its desirable \u201cside effects\u201d is weight loss<\/strong>! Of course, for best results, don\u2019t forget to eat a healthy diet and exercise more often, in addition to taking inositol daily.<\/p>\n\n\n\n
![\"Inositol](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/7-2.jpg\")
<\/figure>\n\n\n\n10 health benefits for women<\/h3>\n\n\n\n
1. Inositol powder helps manage PCOS symptoms<\/h4>\n\n\n\n
PCOS may not be a life-threatening condition on its own. But if left untreated, it can lead to more serious conditions like type 2 diabetes, heart disease, liver inflammation, endometrial cancer, etc. Unfortunately, there is no cure yet for PCOS, but you can keep its symptoms under control<\/strong>.<\/p>\n\n\n\n
Inositol is widely considered as safe and effective for PCOS<\/strong> and multiple clinical studies support this fact (2, 7<\/a>, 8<\/a>).<\/p>\n\n\n\n
2. Improve egg quality in women with PCOS<\/h4>\n\n\n\n
A woman\u2019s egg quality is essential to a healthy pregnancy, but a lot of factors can lead to poor egg health. These include a woman\u2019s age, lifestyle, stress levels, diet, and of course, PCOS.<\/p>\n\n\n\n
According to a study published in the Fertility and Sterility Journal, women who took 2g of inositol twice a day along with 400mcg of folic acid had better egg quality<\/strong> than the women who took folic acid alone (9<\/a>).<\/p>\n\n\n\n
![\"Inositol](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/8-3.jpg\")
<\/figure>\n\n\n\n3. Restore normal menstrual cycle<\/h4>\n\n\n\n
A 2010 study showed that a combination of inositol plus folic acid not only restored menstrual cycles but also resulted in higher pregnancy rate<\/strong> (10<\/a>)!<\/p>\n\n\n\n
4. Improve fertility<\/h4>\n\n\n\n
So, a woman\u2019s fertility is driven by egg quality. As you\u2019ve learned so far, inositol can help improve a woman\u2019s egg quality and restore normal menstrual cycles.<\/p>\n\n\n\n
Add the other beneficial effects of inositol powder, and it\u2019s no surprise that it will also have a positive effect on women\u2019s fertility<\/strong> (8, 9).<\/p>\n\n\n\n
5. Lowers testosterone levels in PCOS women<\/h4>\n\n\n\n
While testosterone is a male hormone, it is present in both men and women. However, women with PCOS have higher testosterone levels than normal<\/strong>. This is why most PCOS women have \u201cmasculine\u201d symptoms. The hirsutism or excessive hair growth following a male distribution pattern, female pattern hair loss, severe acne, and the irregular periods.<\/p>\n\n\n\n
By taking inositol and folic acid<\/strong>, testosterone levels go back to normal<\/strong>. This keeps the acne and hirsutism in check, as well as improves ovulation and fertility in PCOS women<\/a><\/strong> (2).<\/p>\n\n\n\n
6. Gets rid of hirsutism<\/h4>\n\n\n\n
Some women embrace hirsutism (or at least learn to live with it), others not so much. If you belong to the latter group, try taking inositol! A 2008 study demonstrated just how powerful inositol is when it comes to balancing sex hormones. After 6 months of taking inositol, 46 hirsute women finally got rid of the unwanted hair growth<\/strong>! Inositol worked to decrease androgen levels and increase estrogen levels (11<\/a>).<\/p>\n\n\n\n
![\"Inositol](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/9-4.jpg\")
<\/figure>\n\n\n\n7. Prevents gestational diabetes<\/h4>\n\n\n\n
Pregnancy is considered a gift by many women. But getting pregnant is just the first step. Preventing gestational diabetes is high up on the pregnancy to-do list<\/strong>. Why? Because it can cause a lot of problems. It can lead to preeclampsia (high blood pressure), hypoglycemia (low blood sugar), and an extra large baby (which makes normal delivery impossible).<\/p>\n\n\n\n
Unfortunately, gestational diabetes is prevalent amongst obese and overweight pregnant women. Fortunately, inositol helps reduce the risk of gestational diabetes in this demographic<\/strong> (12<\/a>).<\/p>\n\n\n\n
As a preventive measure, women with PCOS and\/or a family history of type 2 diabetes should consider taking inositol to protect against gestational diabetes.<\/p>\n\n\n\n
8. Supports postmenopausal women<\/h4>\n\n\n\n
Periods are one of the most uncomfortable things women go through in life. We bleed for a few days every month, like clockwork, for about 40 years! So, it\u2019s easy to think we\u2019re finally getting a break once we hit menopause.<\/p>\n\n\n\n
But the decrease in estrogen and progesterone levels during menopause can lead to other conditions<\/strong>, such as an increased risk in developing metabolic syndrome and cardiovascular disease.<\/p>\n\n\n\n
A healthy lifestyle and balanced diet are recommended to manage these conditions but supplementing with inositol also helps. According to a recent study, taking as little as 2g of inositol daily is enough to see improvements in cholesterol & triglyceride levels, blood pressure, and HOMA index<\/strong> (13<\/a>).<\/p>\n\n\n\n
![\"Myo](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/10-1.jpg\")
<\/figure>\n\n\n\n9. Helps clear up hormonal acne<\/h4>\n\n\n\n
From apple cider vinegar, honey, witch hazel, green tea, to aloe vera and tea tree oil, there seems to be no shortage of home acne treatments. Some of these options may work, but if<\/strong> the root cause of your acne is hormonal (as is the case with PCOS), then none may be effective<\/strong>. In that case, inositol may be your best bet.<\/p>\n\n\n\n
Italian researchers gave 50 PCOS patients with moderate acne 2g of inositol twice a day for 6 months. By the time the study concluded, the patients taking inositol showed lower DHEAS (dehydroepiandrosterone) blood levels and improved skin conditions<\/strong>! This led the researchers to conclude that inositol can indeed be used to help treat hormonal acne (14<\/a>).<\/p>\n\n\n\n
10. Helps breastfeeding moms<\/h4>\n\n\n\n
As with most supplements and medications, it\u2019s important to speak with your doctor before taking anything, especially if you\u2019re pregnant or breastfeeding. That said, human breastmilk is naturally rich in inositol. It is actually the third most concentrated nutrient in breastmilk, right after lactose and glucose (15<\/a>).<\/p>\n\n\n\n
Inositol for men – it helps improve sperm quality and fertility<\/h3>\n\n\n\n
According to a study published in the International Journal of Endocrinology, 45 men with metabolic syndrome and asthenospermia were given 1g of inositol (+ antioxidants) twice a day for 3 months. By the end of the study, the volunteers showed significant increase in insulin sensitivity and testosterone levels, as well as improved sperm quality<\/strong> (motility, concentration, and morphology) (16<\/a>). <\/p>\n\n\n\n
![\"Inositol](\"https:\/\/eu.intelligentlabs.org\/wp-content\/uploads\/2025\/07\/11-1.jpg\")
<\/figure>\n\n\n\nInositol dosage<\/h2>\n\n\n\n
Inositol doesn\u2019t have a recommended daily intake (RDI) like most other nutrients. This is because it is not considered an essential nutrient, since our bodies can make inositol on its own. But here are some suggested inositol dosage to help treat or manage various conditions:<\/p>\n\n\n\n
- \n
- Insulin sensitivity \u2013 2g twice daily <\/li>\n\n\n\n
- Type 2 diabetes \u2013 2g twice daily<\/li>\n\n\n\n
- PCOS – 2g twice daily + 400mcg folic acid\n
- \n
- Improve egg quality<\/li>\n\n\n\n
- Restore menses<\/li>\n\n\n\n
- Improve fertility<\/li>\n\n\n\n
- Lower testosterone<\/li>\n\n\n\n
- Get rid of hirsutism<\/li>\n\n\n\n
- Weight loss<\/li>\n\n\n\n
- Hormonal acne<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Metabolic syndrome \u2013 2g twice daily\n
- \n
- Reduce blood triglyceride levels<\/li>\n\n\n\n
- Lower LDL & total cholesterol<\/li>\n\n\n\n
- Reduce blood pressure<\/li>\n\n\n\n
- Lower blood sugar<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Depression – 12g for 4 weeks <\/li>\n\n\n\n
- Panic disorder – 12g for 4 weeks <\/li>\n\n\n\n
- Obsessive compulsive disorder – 18g for 6 weeks <\/li>\n\n\n\n
- Bipolar disorder – 2g inositol + 3g omega-3<\/li>\n\n\n\n
- Psoriasis caused by lithium \u2013 3g daily <\/li>\n\n\n\n
- Gestational diabetes \u2013 2g twice daily + 400mcg folic acid <\/li>\n\n\n\n
- Postmenopausal support – 2g twice daily <\/li>\n\n\n\n
- Breastfeeding support \u2013 2g-4g daily<\/li>\n<\/ul>\n\n\n\n
Possible side effects of inositol<\/h2>\n\n\n\n
As you may have noticed in the list above, most conditions require 4g of inositol powder per day. However, even at high doses of up to 18g, inositol is still considered relatively safe and side effects remain relatively minor<\/strong>. Side effects include nausea, headache, dizziness, tiredness, gas, and stomach pain (17<\/a>).<\/p>\n\n\n\n
Some people may experience side effects during the first few days. To let your body get used to the supplement, we recommend taking inositol at a lower dose first (2g). After a few days, you can increase the inositol dosage to 4g per day.<\/p>\n\n\n\n

<\/figure>\n\n\n\nFrequently asked questions about inositol powder<\/h2>\n\n\n\n
Can I get inositol from food?<\/strong><\/p>\n\n\n\n
Yes, there are plenty of foods rich in inositol. Here are some of them:<\/p>\n\n\n\n
- \n
- Vegetables \u2013 green leafy veggies, bell pepper, asparagus, potatoes<\/li>\n\n\n\n
- Beans \u2013 navy beans, lima beans<\/li>\n\n\n\n
- Fruits \u2013 fresh citrus fruits like oranges, pears, peaches, cantaloupes, bananas<\/li>\n\n\n\n
- Whole grains \u2013 brown rice, wheat bran, corn<\/li>\n\n\n\n
- Nuts and seeds<\/li>\n\n\n\n
- Meat and eggs<\/li>\n<\/ul>\n\n\n\n
What will happen if I go beyond the recommended dosage?<\/strong><\/p>\n\n\n\n
Inositol powder is a relatively safe supplement. In studies where volunteers were given 12g-18g daily, only minor side effects presented, such as gas, nausea, tiredness, and stomach pain.<\/p>\n\n\n\n
- High density lipoprotein (HDL)<\/strong> \u2013 this is \u201cgood\u201d cholesterol. Raised HDL levels lower the risk of stroke and heart disease.<\/li>\n<\/ul>\n\n\n\n
- Low-density lipoprotein (LDL)<\/strong> \u2013 this is \u201cbad\u201d cholesterol. High LDL levels increase the risk of stroke and heart disease.<\/li>\n\n\n\n
- Our kidneys make about 2 grams of inositol<\/strong> from glucose (which is converted from the carbohydrates we eat).<\/li>\n\n\n\n
