Inositol: What It Is and What It Does in the Body

Inositol was once called vitamin B8. It no longer counts as a vitamin, because your body makes its own — which is exactly what makes it an unusual supplement ingredient, and worth understanding properly.

What this page is. Background on the ingredient inositol. It is not a description of what Kura Mynis does. Kura Mynis is a food supplement, not a medicine, and is not intended to diagnose, treat, cure or prevent any disease.

01 — Definition

What is inositol?


Inositol is a sugar alcohol — structurally an isomer of glucose, meaning it shares glucose’s chemical formula but arranges it differently. It occurs naturally in the body and in a wide range of foods, and it is found in particularly high concentrations in the brain, where it participates in cell signalling.

It was classified as vitamin B8 until researchers established that humans synthesise it from glucose. Since a vitamin is by definition something the body cannot make, the classification was dropped. It is now described as a vitamin-like compound.

02 — Forms

Why does Kura Mynis use myo-inositol?


Inositol exists as nine stereoisomers — same atoms, different three-dimensional arrangements. Five of these occur in nature. Myo-inositol is by a wide margin the most abundant in human tissue and the most biologically active, which is why it is the form used in research and in supplements.

Myo-inositolThe dominant naturally occurring form and the one present in most published research. This is the form used in Kura Mynis.
D-chiro-inositolA less abundant isomer converted from myo-inositol in the body. Studied less often and at much lower doses.

03 — Mechanism

What does inositol actually do in the body?


Inositol acts as a second messenger. When a hormone arrives at a cell, it usually cannot enter — it docks at a receptor on the outside. Something then has to carry that instruction inward. That relay role is what second messengers perform, and inositol-derived molecules are among the most important of them.

Inositol participates in the signalling pathways of several hormones, including:

  • Insulin — the hormone that regulates how cells take up glucose from the bloodstream.
  • Thyroid-stimulating hormone (TSH) — which governs thyroid activity.
  • Follicle-stimulating hormone (FSH) — part of reproductive hormone regulation.

Being involved in a hormone’s signalling pathway is not the same as controlling that hormone. Inositol is one component of a large and heavily redundant system. Supplementing it does not hand you control over insulin, thyroid function or anything else.

04 — Diet

Where does inositol come from in food?


Inositol is widespread in ordinary diets. The richest sources are:

Food groupExamples
Whole grainsHigh-bran cereals, wheat bran, oats
LegumesBeans, chickpeas, lentils
Nuts and seedsAlmonds, walnuts, sesame
FruitCitrus fruit, cantaloupe, stone fruit

In grains and legumes much of it is present as phytic acid, which the body converts to free inositol during digestion. Someone eating a varied diet with plenty of whole grains, beans and fruit is already taking in inositol daily.

05 — The evidence

What does the research show?


Inositol has been studied in the context of insulin signalling and metabolic markers, and it is an active research area. Results across trials are not uniform, study populations differ substantially, and doses vary widely — so the honest position is that the picture is still developing rather than settled.

Some of the published inositol literature involves specific clinical populations under medical supervision. We have deliberately left that research off this page. Kura Mynis is a general food supplement sold without a prescription, and reproducing clinical-population findings on a product website invites readers to draw conclusions that the product does not support and that we are not qualified to encourage.

If you have a diagnosed condition, the right source of information about inositol is the doctor treating you — not a supplement website, including this one.

06 — In the formula

Why is inositol in Kura Mynis?


Inositol is included as one component of a multi-ingredient daily formula, alongside white bitter melon, yuzu extract, InSea2® brown seaweed, acacia gum and a lemon bioflavonoids complex. It is present as myo-inositol, the form found in the body and used in published research.

Kura Mynis is intended to complement a balanced diet. It is not a treatment for any condition and not a substitute for prescribed medication.

07 — Cautions

Who should be careful with inositol?


  • Pregnant or breastfeeding. Kura Mynis is not formulated for use during pregnancy or breastfeeding. Speak to your doctor before taking any supplement at these times.
  • Taking prescribed medication. Check with your doctor or pharmacist before adding a supplement, particularly medication for blood sugar or thyroid function.
  • Managing a diagnosed condition. Do not use a supplement in place of, or to delay, medical care.
  • Children. Kura Mynis is formulated for adults.

Not any more. It was once classified as vitamin B8, but the classification was dropped once it was established that the human body synthesises inositol from glucose. A vitamin is by definition a nutrient the body cannot make. Inositol is now described as a vitamin-like compound.

Myo-inositol is one specific form of inositol. Inositol exists as nine stereoisomers, five of which occur naturally, and myo-inositol is the most abundant in human tissue and the most biologically active. When a product lists “inositol” it usually means myo-inositol.

High-bran cereals and whole grains, beans and other legumes, nuts and seeds, and fruit such as citrus and cantaloupe. In grains and legumes much of it is bound as phytic acid, which is converted to free inositol during digestion.

Kura Mynis is not formulated for use during pregnancy or breastfeeding. Any supplement taken during pregnancy should be discussed with your doctor or midwife first, as they can advise on your individual situation.
