What is D-chiro inositol 100 mg?
When you start looking into inositol, one name comes up again and again: myo-inositol. It’s the best-known form and one of the most studied. But inositol also comes in other forms, and D-chiro-inositol features prominently in research on women’s nutrition.
D-chiro inositol 100 mg from EssentialSeries is our food supplement in vegetable capsules, combining this form of inositol with zinc, chromium and vitamin B6. We’ve brought together a specific ingredient, selected nutrients and a practical format to make it easy to add to your diet.
It’s an especially interesting option for women who already know about myo-inositol and also want to add D-chiro-inositol, or who prefer to choose products separately rather than go straight for a formula containing both.
At HSN, we offer different inositol products and formulas designed for women. So you can choose individual ingredients, capsules or powder preparations, with clear information on what each option contains.
Myo-inositol and D-chiro-inositol: two forms worth knowing
Inositol is a compound found naturally in the body and in various foods. It can take several forms, known as isomers. Think of it as using the same pieces to build different shapes: the components are the same, but they’re arranged differently.
Myo-inositol and D-chiro-inositol are two of those forms. Myo-inositol is the most abundant in nature and the one you’ll usually come across when inositol is discussed in relation to diet and supplementation.
D-chiro-inositol has a different arrangement of those same components. The body can produce it from myo-inositol through a transformation involving proteins called enzymes.
This connection explains why the two names appear together so often. When choosing a food supplement, knowing which form of inositol it contains helps you distinguish between a myo-inositol product, a D-chiro-inositol product and a formula containing both.
Our D-chiro inositol clearly identifies the form used. That way, you know which ingredient you’re adding and where it fits among the different options in our range.
Why are myo-inositol and D-chiro-inositol combined?
The two forms are connected within the body, but they aren’t present in the same amounts in every tissue. Studies of this physiological relationship have sparked interest in the relative amounts of myo-inositol and D-chiro-inositol and how they appear in different contexts. (Unfer et al., 2014)
This interest has led to supplement formulas containing both forms of inositol. Trials comparing different ratios have also been published, along with reviews examining their use individually and together. (Nordio et al., 2019; Fitz et al., 2024)
When we talk about a ratio, we mean the amount of one form compared with the other. So two products can both contain myo-inositol and D-chiro-inositol yet have different compositions. It’s a useful detail when getting to know the formulas and choosing the combination you’re looking for.
At HSN, we offer D-chiro-inositol separately so you can add it alongside our myo-inositol as part of a routine that works for you. We also have formulas that bring both forms together in a defined composition.
Which option you choose depends on your preferences, the products you already use and the nutritional guidance you follow. There are different formats to help you find the best fit.
Zinc, chromium and vitamin B6: a combination worth exploring
We’ve paired D-chiro-inositol with nutrients that offer benefits in areas of particular interest: normal fertility and reproduction, hormonal activity and nutrient metabolism.
- Zinc contributes to normal fertility and reproduction. It also contributes to the normal metabolism of carbohydrates.
- Vitamin B6 helps to regulate hormonal activity and contributes to normal energy-yielding metabolism. We’ve included it alongside the minerals to round out the formula with a vitamin of particular interest.
- Chromium contributes to maintaining normal blood glucose levels. It also contributes to the normal metabolism of macronutrients found in the everyday diet, such as carbohydrates, fats and proteins.
With this selection, you get D-chiro-inositol alongside important micronutrients with specific functions. It’s an easy-to-understand formula for anyone looking for more than inositol alone.
HSN quality: we take care with the raw materials and how we make the product
The quality of a food supplement starts long before it reaches the packaging. Choosing suppliers, checking ingredient specifications and carrying out controls during manufacturing are all part of the work behind every product.
At HSN, we’re directly involved in development and manufacturing. This lets us work on the formula, select the raw materials and oversee production through to the finished product.
Selected raw materials and clearly identified forms
We review suppliers and raw material documentation to check that their specifications meet our requirements. Ingredient identity, composition and quality controls all form part of that selection.
For our D-chiro inositol, we’ve chosen zinc in the form of citrate and chromium in the form of picolinate. Identifying these sources helps you understand the formula and see how each mineral is included.
We also pay attention to ingredient quality and the control of any contaminants. This work brings together documentation, testing and manufacturing procedures, followed by checks on the finished product.
For you, all this means a choice backed by a team that works on both the formula and the quality of the product you receive.
Clean label and transparency: know what’s inside
At HSN, we work to keep our formulas simple and choose the ingredients we use carefully. Our clean label approach prioritises ingredients of nutritional interest and the justified use of components needed to make the product.
This approach comes with clear information. In D-chiro inositol, we identify the form of inositol, the accompanying nutrients and the mineral sources. You can see what the formula contains and how it’s been put together.
For minerals, we also distinguish between the amount of the source used and the amount of mineral it provides. Zinc citrate provides zinc, and chromium picolinate provides chromium: the total weight of these substances includes other components besides the mineral itself.
That’s why we state the actual zinc and chromium content. This helps you understand how much each mineral the product provides and compare products using a more useful reference than the weight of the complete mineral salt.
Controlling cross-contamination during manufacturing
Cross-contamination is the unintended transfer of particles from one ingredient to another during handling or manufacturing. Preventing it is part of our manufacturing procedures.
We use isolation measures when handling ingredients, air filtration systems and procedures for cleaning equipment and surfaces. These measures help control unwanted transfers during production.
Staff training and the way we organise operations are also part of this work. We take care over how raw materials are handled and how equipment is prepared for different processes.
We also carry out checks during manufacturing and on the finished product. So ingredient selection is backed by oversight of the process used to make our capsules.
In-house manufacturing and quality at the Right Price
At HSN, we develop, manufacture and sell our products directly to you. This model lets us coordinate decisions from selecting raw materials to preparing the product delivered to your home.
By bringing these stages together, we reduce the number of intermediaries and can make better use of our resources. Production planning, purchasing and product management all contribute to that efficiency.
This is the basis of our Right Price policy: offering products with selected ingredients and quality controls at a price that reflects our direct manufacturing and sales model.
When you choose D-chiro inositol, you get a formula made by HSN, with a clearly identified composition and the backing of our quality processes. It’s designed to help you stick with your supplement choice while getting a good balance of composition, quality and price.
We develop, manufacture and sell nutrition: HSN quality at the Right Price.
Who might D-chiro inositol suit?
It may be especially suitable for adult women interested in inositol who want to explore options beyond myo-inositol. It may also suit those who already use myo-inositol and want to add D-chiro-inositol to a combination.
It’s an option for anyone who prefers to have the products separately. This format lets you choose D-chiro-inositol without opting for a complex that also includes myo-inositol and other additional ingredients.
It’s convenient if you like to take food supplements with you. The capsules are taken with water, so you can add the product to your routine without preparing a drink or adding a flavour to your diet.
The entire formula, including the capsule, is also suitable for vegan and vegetarian diets. You can choose it while sticking to your dietary preferences.
How to make it part of your day
To make it easy to add to your routine, you can take it at a regular time of day and follow the directions on the packaging. A convenient format helps keep the habit simple, whether you’re at home or your schedule changes.
If you use several food supplements, knowing what each contains helps you organise your choices. In our range, you’ll find both individual ingredients and formulas that already combine different nutrients.
All this can be part of a routine that includes a varied diet, physical activity and rest, with supplement choices tailored to your needs.
What can you combine it with? Choose your inositol option at HSN
The most straightforward combination is with our RawSeries myo-inositol powder. It contains only myo-inositol, with no additives, letting you add this form as a powder while taking D-chiro-inositol in capsules.
If you value a single-ingredient clean label option, the RawSeries format offers exactly that simplicity: myo-inositol as the only ingredient. You can add it to a drink and take it alongside our D-chiro inositol according to the combination you follow.
This pair of products is an interesting option if you want the two forms separately. The powder gives you flexibility when preparing a drink, while the capsules keep D-chiro-inositol ready to take.
If you’d rather have a food supplement that already contains both forms, we have other HSN options.
Two forms of inositol in one formula: explore our alternatives.
Pmos care from Care Nutrition combines myo-inositol and D-chiro-inositol with berberine from Berberis aristata, vitamins and minerals. Its vegetable capsules are a good fit if you’re looking for a combined formula that’s ready to take.

Pmos care and Pmos complex powder already contain both forms of inositol. You can choose them instead of individual ingredients, depending on the format and composition that best fit your diet.
Frequently asked questions
Are D-chiro-inositol and myo-inositol the same thing?
They’re two different forms of inositol. They share the same components, but those components are arranged differently within the molecule. The body can convert myo-inositol into D-chiro-inositol, which explains the connection between them.
Does this product also contain myo-inositol?
The inositol in this formula is D-chiro-inositol, accompanied by zinc, chromium and vitamin B6. If you’d also like to add myo-inositol, you can find it separately in our range or choose a formula containing both forms.
What’s the difference between zinc citrate and the zinc it provides?
Zinc citrate is the ingredient we use as a source of this mineral. Part of its weight is zinc. In our nutritional information, we show both figures separately so you can see the actual amount of the mineral provided.
Can I find both forms of inositol in one HSN product?
Yes. Pmos care and Pmos complex powder contain myo-inositol and D-chiro-inositol, along with other ingredients. They’re options for anyone who prefers a combined formula in capsules or powder.
Is it suitable for vegans and vegetarians?
Yes. Both the formula and the capsule are suitable for vegan and vegetarian diets. We’ve considered the entire composition to offer you this option in our range.
