DCI Test?

I am obese and have PCOS. How do I know if I have DCI deficiency? Is it assumed that I do since I have been diagnosed with PCOS? I read the only way to test for DCI is through a muscle biopsy. Is it possible to overload the body with DCI? I know I'm being skeptical. I have read the studies and the outcomes seem to good to be true. I guess I just can't believe My doctors have never told me about this supplement. Thank you for the information! 

Hi Theresa—
PCOS is a complicated syndrome which likely has numerous causes and aggravating factors. There is not a commercial test for DCI levels, although a urinalysis is possible and may become commercially available at some point in the future. 
Since DCI is water soluble and a natural human metabolite, it would take an extreme amount of Chiral Balance DCI to cause any adverse affects, the worst of which would probably be diarrhea and resulting dehydration. This is not a concern if taken as directed. 
The studies were peer-reviewed and published in highly respected journals so there is no cause for concern about their validity. That said, skepticism is healthy, and it is important to note that the reported results are the average of several women, some of whom responded very positively and some of whom may not have responded at all. In fact, given the many facets and factors of PCOS, it is unlikely that DCI will work for everyone equally well. However, we provide a money back guarantee* on any customer's first order to accommodate that fact. 
And, don't be surprised that your doctors never told you about Chiral Balance DCI. The average woman with PCOS will see six doctors before getting a correct diagnosis, and then she will almost invariably be prescribed metformin and/or oral contraceptives. A nutritional approach like Chiral Balance DCI is easy to overlook.

*We don't like to call it a guarantee anymore. It is important to understand that not every woman with PCOS will see benefit from DCI therapy. Not every woman develops PCOS as a result of insulin resistance; not all women develop insulin resistance as a result of DCI deficiency. That's why we don't call it a guarantee. Instead, we would like you to know that you can try DCI risk-free for up to 60 days. If DCI doesn't help you, let us know and we will refund your purchase. We want you to find the solution for your PCOS!

One thing that has not changed since this was written: it is still difficult for PCOS women to find the help that they need. Awareness is rising, but PCOS is still overlooked all too often. And many doctors still do not do enough to help women with PCOS. It is imperative that you advocate for yourself—learn as much as you can about PCOS and your situation in particular. Find a doctor that listens to you and treats you well. It will make all the difference.

Thyroid Medication

I take compounded thyroid every morning 1/2 hour before intake of food. I just received my first bottle of D-Chiro and the instructions seem to be the same in the morning same time before food intake. What is the conflict if any for absorption of my thyroid medication - if taken at same time as the D-chiro-inositol? Please advise.


Hi Annie— 
It is not known whether or not D-chiro-inositol affects the absorption of thyroid medications. For that reason, Chiral Balance recommends taking our DCI later in the day*, either before your mid-day meal or last meal of the day, at the same time each day. Thank you for your question and we will be adding a more thorough discussion of DCI and thyroid medications to the knowledge base as soon as possible.

*Since this was written, we've modified our recommendation for when to take DCI if you are taking thyroid medication: follow the recommendation for when it is okay to eat food. That is, if you must wait 90 minutes before eating food, then wait 90 minutes to take your DCI. 


I can't say enough about your product.

We tried to conceive for almost 3 years, but we had difficulty due to my irregular (almost nonexistent) cycles.

I am not overweight, so my first doctor told me I could not have PCOS. I did my own research and found a new doctor! I fortunately found your product, and I noticed an immediate difference in my body. I found out I was pregnant within several months.

We now have a beautiful 1 1/2 year old daughter.

I can't thank you enough.


This obviously wasn't a question, but it brings up a very good point about doctors. If you're not getting the care you need and deserve, find a new doctor!

Like so many women with PCOS, Angie was seeing a doctor who didn't understand her condition. The doctor didn't know that not every woman with PCOS is overweight. This and other misunderstandings are common, even in the medical community. That is why it is vital that you find a doctor that understands this condition and has the skills to treat it. You deserve it!

Is DCI Made in China?

I placed an order to try this DCI for 1 month to check it out, but am concerned this D-chiro-inositol is from China or somewhere that I do not trust - please advise. 

Hi Annie—

Chiral Balance DCI is manufactured in South Korea*, in compliance with the country's strict FDA regulations. South Korea doesn't suffer from the lack of oversight and regulation that may have allowed Chinese manufactures to put dangerous products on the market. Chiral Balance DCI is imported to the United States, at which point it undergoes additional testing for pesticides, heavy metals, pathogens, and more chemicals to confirm that it meets United States FDA standards Chiral Balance D-chiro-inositol is put into capsules and bottles at a cGMP facility in Florida. Chiral Balance DCI has been safely used by thousands of customers since 2005.

*Since that answer was written six years ago, we have begun contracting with Euronutra to manufacture our DCI. Euronutra is located in Malaga, Spain, and is subject to rigorous testing and licensure under the laws of Spain and the EU. Furthermore, Euronutra is an FDA-inspected facility.
