Inositol Supplements Guide


Inositol supplements are natural nutritional supplements sold over the counter to anyone who would like to try the effects of natural supplements to better their mental health without synthetic or chemical drugs.

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 because of the quality research and proven neurological results.

Inositol supplements are commonly added to general women’s health complex supplements as this vital nutrient seems to have more of an effect on women than on men, and are often recommended for a host of female hormonal issues such as PMS, PCOS, depression, anxiety, and mood swings related to hormone imbalance, and panic attacks.

What is Inositol?

Inositol is a cofactor for neurotransmitters in the human brain that are responsible for regulating mood. Basically, it helps send signals through your brain to regulate mood. It is found in many foods, quite highly in whole grains, citrus fruits, melon, and white beans.

It is a pseudovitamin of the vitamin B complex, but unlike other classified B vitamins, the human body can synthesize this important nutrient in the kidneys, but sometimes fails to make it in the amounts needed for healthy brain function.

Inositol relays messages from neurotransmitters, such as dopamine and serotonin, from one brain cell to another, completing a communication cycle that tells you to be happy, calm, and relaxed. Without inositol, the brain can’t send these messages, resulting in anxiety, depression, and other mood disorders.

Benefits of Inositol

  • Inositol may help people with anxiety disorders as a natural anti-anxiety and panic attack remedy. Because it works in the brain to help regulate mood, it may suppress spikes in anxiety and panic.
  • Inositol supplements may help reduce the effects of Obsessive Compulsive Disorder by allowing the brain’s neurotransmitters to communicate effectively.
  • High doses of inositol have a high rate of reduction of depression, anxiety, and binge eating related to bulimia.
  • Inositol may help women say goodbye to PMS symptoms such as mood swings and irritability and may be effective in treating premenstrual dysphoric disorder
  • Inositol has been proven to be an effective treatment for Poly Cystic Ovary Syndrome by normalizing hormone levels of testosterone and insulin and boost the health of cells to promote pregnancy.
  • Is effective in treating insulin resistance and therefore some users may experience weight loss as the body becomes more readily able to process insulin, though the supplement is not recommended solely for weight loss.
  • Up to 2 grams of inositol a day may be helpful in blood sugar regulation
  • Inositol has shown some promising results for improving cognitive brain function such as memory, learning, and focus.
  • People suffering from sleep disorders may find some results by taking Inositol before bed because it works as a neurotransmitter receptor for serotonin – a chemical that helps level mood and may help with proper sleep.

Are There Any Side Effects?

There are not any major known side effects of inositol supplements. Inositol, or its most common supplement form Myo-inositol, is considered very safe to ingest. Any side effects reported have been mild (none severe or life threatening) and only include mild gastrointestinal distress at high doses.

No incidences of drug interactions or contraindications were found. Inositol combined with other supplements or ingredients could have side effects not addressed here, so be sure to read your labels and only purchase single-ingredient supplements when possible.

How to Take Inositol Supplements

The dose and frequency of inositol supplements varies from user to user and from ailment to ailment. Generally, any neurological disorders require quite a high dose of the supplement while uses such as PMS, sleep disorders, blood sugar regulation, and insulin resistance use a lower dose.

Check with your physician or health practitioner for advice on the correct use and dosage for your particular ailment. Taking the supplement first thing in the morning will help your body have the nutrient readily available for use throughout the day, though for some applications, such as trouble sleeping, it may be best taken at night.

For treating anxiety and depression in people who are not taking anti-anxiety medications or antidepressants, high doses are recommended with good results. Take 14-18 grams daily. This high dose is best taken in the morning when neurotransmitters are mostly at rest, with food to help with any stomach upset, and most easily taken in powder form, mixed into a beverage to avoid having to swallow many pills.

For treating Poly Cystic Ovary Syndrome, a dose of 4,000mg once daily before breakfast is recommended as the most effective dose. This high dose is best taken in powder form mixed into a beverage.

Because these high doses may cause stomach upset or mild gastrointestinal upset, you may want to start with a small dose and work up to the full dose for maximum results without the irritation. 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. Be sure to find the inositol supplement that contains myo-inositol and d-chiro inositol if you are trying to treat Poly Cystic Ovary Syndrome.

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 digestLook 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.
