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 widely studied. But inositol also comes in other forms, and D-chiro-inositol features prominently 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 add to your diet.

It’s an especially interesting option if you already know myo-inositol and want to add D-chiro-inositol too, or if you 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. You can choose individual ingredients, capsules or powders, 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. To picture it, imagine using the same pieces to build different shapes: the components stay 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 people talk 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 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 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 while having 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 suits you. We also have formulas that already 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 right 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 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 maintaining normal blood glucose levels. It also contributes to the normal metabolism of macronutrients found in everyday foods, such as carbohydrates, fats and proteins.

With this selection, you get D-chiro-inositol alongside important micronutrients with specific functions. It’s a straightforward formula for anyone looking for more than inositol alone.

HSN quality: care goes into the ingredients and the way 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 manufacturing controls 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 our suppliers and raw material documentation to check that the specifications meet our requirements. Ingredient identity, composition and quality controls all form part of this selection.

For our D-chiro inositol, we’ve chosen zinc in citrate form and chromium in picolinate form. 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, 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 in the formula

At HSN, we work to keep our formulas simple and select ingredients with care. Our clean label approach prioritises ingredients of nutritional interest and uses other components only where they’re needed to make the product.

Clear information goes hand in hand with this approach. With 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 the minerals, we also distinguish between the amount of the source ingredient and the amount of mineral it provides. Zinc citrate provides zinc, and chromium picolinate provides chromium: the full weight of each substance includes components other than the mineral itself.

That’s why we state the actual zinc and chromium content. It gives you a clearer picture of the amounts provided and a more useful basis for comparing products than the weight of the entire mineral salt.

Controlling cross-contamination during manufacturing

Cross-contamination is the unintended transfer of particles from one ingredient to another during handling or production. Preventing it is part of our manufacturing procedures.

We use measures to keep ingredients separate during handling, 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 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 production and on the finished product. So careful 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 everything from selecting raw materials to preparing the product that arrives at your door.

Bringing these stages together reduces the number of 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.

Who might D-chiro inositol suit?

It may be a particularly good fit 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 their combination.

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

The format is handy if you like taking food supplements with you. The capsules are taken with water, so there’s no drink to prepare and no extra flavour to add 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 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 routine simple, whether you’re at home or your schedule changes.

If you use several food supplements, knowing what each one contains can help you organise your choices. In our range, you’ll find both individual ingredients and formulas that already combine different nutrients.

All of this can form 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 direct pairing is our RawSeries myo-inositol powder. It contains only myo-inositol, with no additives, so you can take this form as a powder while keeping D-chiro-inositol in capsules.

If you value a single-ingredient clean label option, the RawSeries powder offers just that simplicity: myo-inositol as its only component. You can mix it into a drink and take it alongside our D-chiro inositol according to the combination you follow.

This pair of products is worth considering 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.

Pmos care and Pmos complex powder already contain both forms of inositol. You can choose them instead of separate ingredients, depending on which format and composition 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 like to add myo-inositol too, 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 the source of this mineral. Part of its weight is zinc. We show both figures in our nutritional information so you can see the actual amount of 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 vegan and vegetarian diets. We’ve considered the full composition to offer this option in our range.
