Inositol Supplements Guide

What Are Inositol Supplements?

If you eat a healthy diet, you’re already consuming some inositol. That’s because it is a naturally occurring compound that’s found in certain foods and has vitamin-like properties, and it is a sugar that has half the sweetness of table sugar. Some sources refer to it as vitamin b8. However, it also can be produced in the lab, and it’s even made in the human body.

Inositol supplements are natural nutritional supplements sold over the counter. They are available without a prescription from major nutrition and vitamin stores, warehouse stores, and large pharmacies, though your doctor or other health professional may be the one to recommend this supplement to you.

Where Do Inositol Supplements Come From?

It depends on the manufacturer that you choose. Many inositol supplements are created using naturally occurring, but many others are made with synthetically produced inositol.

Inositol can be found in the following foods:

  • Wheat germ
  • Liver
  • Banannas
  • Brown rice
  • Oat flakes
  • Unrefined molasses
  • Raisins
  • Vegetables
  • Nuts
  • Rice
  • Brewer’s yeast
  • Other fruits

What Are They Used For?

Inositol supplements are not used for the diagnosis, prevention, or treatment of any disease. However, WebMD feels that they could be beneficial for people who suffer from several conditions, and some of its uses are rated “possibly effective” according to the website. One study indicated that they might reduce one’s risk of gestational diabetes by 60 to 92 percent.

Another study indicates that inositol might be beneficial for people who suffer from psoriasis that is caused by lithium. Preliminary research indicates that it might be useful for people who suffer from metabolic syndrome, and also it might be beneficial for people who suffer from agoraphobia and panic disorder. In addition, preliminary research indicates that it might have uses for people who have polycystic ovary syndrome. It also may have uses for people who suffer from complications that are associated with pregnancy.

Furthermore, some bodybuilders use inositol, and some people believe that supplementation with inositol may help to foster muscular growth. Some people also use inositol to enhance their cognition, but it is unknown if it is effective for this purpose. However, evidence suggests that it plays a role in brain cell signaling, and the highest concentration of endogenous inositol is found in the brain.


There are not any major known side effects of inositol supplements. Inositol, or its most common supplement form Myo-inositol, is considered safe to ingest. Side effects reported have been mild. This does not mean that there are none. Your doctor will be able to give you more information.

In most cases, the side effects, if present at all, are limited to nausea, headache, fatigue, and dizziness. Occasionally, it can cause diarrhea, vomiting, and loss of appetite. If side effects are bothersome or appear significant, stop taking inositol and contact your physician.

However, individuals who have bipolar disorder or are breastfeeding shouldn’t use it. This is because there isn’t enough known about its side effects for women who are breastfeeding, and there is some concern that inositol may worsen bipolar disorder.

A man appeared to have a manic episode that was brought on by consuming several cans of red bull over a four day period, and one of the ingredients of the drink is inositol. However, doctors do not know whether it was inositol that triggered the episode or another ingredient, and some experts suggest that it may have been a combination of ingredients that triggered the episode. It’s always best to speak with your doctor before you begin taking any supplement, including inositol.

Always speak with a medical professional or doctor before taking any supplements. Always read the product label for instructions and directions.

Taking Inositol Supplements

Check with your physician or health practitioner for advice on the correct use and dosage.

The powdered form of this supplement is best for adjusting the dosage and may be easier to digest since it is mixed into a beverage and swallowed with plenty of fluids instead of swallowing a pill that sits in your stomach to dissolve.

What to Look for In a Good Inositol Supplement

A good inositol supplement will have labels with the manufacturer name and location clearly marked and include the country of origin and source of inositol, which should be typically plant based. Vegans will want to purchase the powder form as the capsule form is encapsulated in gelatin.

Inositol has nine different isomers with the most common one being myo-inositol. If the supplement is missing the prefix, you can be fairly certain you are buying myo-inositol, which is the form commonly found in nature and derived from foods.

Inositol is a naturally occurring substance, so you should expect to see the source listed on the bottle.

A good supplement will dissolve completely in water and have very few filler or inactive ingredients other than those required for the composition of the pill and the capsule material, which make it easy to swallow and digest. Look for supplements from major retailers who carry known, trusted brands or generic names. Don’t take supplements that are capped in a holistic store because there is no way to verify purity or hold the manufacturer responsible for any ill effects of impure supplements.

Though nutritional supplements and vitamins are not regulated by the FDA, the manufacturers who make other drugs are subject to FDA inspections to ensure the equipment they use is sterile and free of metal fragments and other undesirable impurities, so it is worth the money to buy supplements from major pharmaceutical manufacturers or brand name labels.

Finally, don’t buy more supplement than you need. Though inositol is commonly mixed with other supplements for women’s health, remember that some supplements and vitamins have negative effects in high doses, such as vitamin A.

So only buy the single-ingredient supplements you need, even if it means taking more pills overall. Buy the powdered form of inositol to easily mix into a beverage in large doses or buy the pill form to take in smaller doses, depending on your use.

The powdered form can be found in large containers or in individual packets, which are very convenient to keep in your bag and mix into your water at lunch time.

Make sure that you choose a reputable manufacturer, and there are several ways to do this. Some inositol supplements are made in an FDA-registered facility, and there are third-party organizations that evaluate supplement manufacturers. Determine if the organization is NSF-certified and/or GMP-compliant. Also, check to see if the manufacturer is registered with the Better Business Bureau.

It’s usually best to purchase the product from a manufacturer that has been in business for a considerable period of time, and you should always read reviews of the company that you’re considering buying the product from. If some reviewers seemed to experience side effects of the product that aren’t typical of inositol, it’s best to stay away from the manufacturer.

Also, read the list of inactive ingredients, and this is especially important for anyone with an allergy. It’s recommended that you always avoid products that contain magnesium stearate.
