D-chiro inositol 100mg

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 has a prominent place in research into 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 include in your diet.

It’s an especially interesting option if you’re already familiar with myo-inositol and want to add D-chiro-inositol too, or if you’d rather choose products separately than go straight for a formula containing both.

At HSN, we offer different inositol formats and formulas for women. That means you can choose individual ingredients, capsules or powder preparations, with clear information about the composition of each option.

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. To picture it, imagine using the same pieces to build different shapes: the components are the same, but their arrangement changes.

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 reading about inositol in food and supplements.

D-chiro-inositol has a different arrangement of those same components. The body can produce it from myo-inositol through a process involving proteins called enzymes.

This connection explains why the two names so often appear together. When choosing a food supplement, knowing which form of inositol it contains helps you tell a myo-inositol product from a D-chiro-inositol product or a formula containing both.

Our D-chiro inositol clearly identifies the form used. That way, you know which ingredient you’re adding and how it fits among the 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 occur 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 separately and together. (Nordio et al., 2019; Fitz et al., 2024)

By ratio, we mean the amount of one form compared with the other. So two products can both contain myo-inositol and D-chiro-inositol but have different compositions. It’s a useful detail when getting to know the formulas and choosing the combination you want.

At HSN, we offer D-chiro-inositol separately so you can add it alongside our myo-inositol as part of a routine that suits 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 considering

We’ve paired D-chiro-inositol with nutrients that contribute to areas of particular interest: normal fertility and reproduction, hormonal activity and nutrient metabolism.

•  Zinc contributes to normal fertility and reproduction. It also contributes to normal carbohydrate metabolism.
•  Vitamin B6 helps 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 the maintenance of normal blood glucose levels. It also contributes to normal macronutrient metabolism, involving nutrients that are part of our 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 the way we make the product

The quality of a food supplement starts before it reaches the packaging. Choosing suppliers, checking ingredient characteristics and carrying out controls during manufacturing are all part of the work behind each product.

At HSN, we’re directly involved in development and manufacturing. This lets us work on the formula, select the raw materials and follow the production process through to the finished product.

Selected raw materials and clearly identified forms

We review suppliers and raw material documentation to check that their characteristics meet our requirements. Ingredient identity, composition and quality controls are all 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 involves documentation, analysis and manufacturing procedures, followed by checks on the finished product.

For you, 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 in the formula

At HSN, we work to simplify our formulas and make considered choices about the ingredients we use. Our clean label approach prioritises ingredients of nutritional interest and the justified use of components needed to make the product.

Clear information goes hand in hand with this approach. For 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 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 declare the actual zinc and chromium content. This lets you see how much each mineral the product provides and compare products using a more useful reference than the weight of the whole mineral salt.

Cross-contamination control 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 cleaning procedures for equipment and surfaces. These measures help control unwanted transfers during production.

Staff training and the way operations are organised are part of this work too. 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 monitoring throughout 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 that arrives at your door.

Bringing these stages together reduces intermediaries and helps us 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 a supplement choice that offers 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 particularly suitable for adult women interested in inositol who want to explore options beyond myo-inositol. It may also suit those already using myo-inositol who want to add D-chiro-inositol to a combination.

It’s an alternative if you prefer to keep products separate. This format lets you choose D-chiro-inositol without opting for a complex that also contains myo-inositol and other additional ingredients.

The format is handy if you like to take supplements with you. You can take the capsules with water, 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. So you can choose it while sticking to your dietary preferences.

How to fit it into your daily routine

To make it easy to include, you can take it at a regular point in your 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 of this can fit into 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, so you can use this form as a powder while taking D-chiro-inositol in capsules.

If you’re looking for a single-ingredient clean label option, the RawSeries powder offers exactly that simplicity: myo-inositol as its 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 choice if you want both forms separately. The powder gives you flexibility when making 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.

Pmos care and Pmos complex powder already contain both forms of inositol. You can choose them instead of individual ingredients, depending on which format and composition best suit 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 also want 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. We show both figures separately in our nutritional information 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 if you prefer a combined formula in capsules or powder.

Is it suitable for vegans and vegetarians?

Yes. Both the formula and the capsule are suitable for a vegan or vegetarian diet. We’ve taken the full composition into account to offer you this option in our range.
