Sources of DCI
SPECIAL NEWS: I have available a limited quantity of DCI powder for sale at a significant discount to other providers. Up to 70% less in fact!
18g packets (= to 60 x 300 mg capsules) of DCI are available for $30 AUD (approx $25 USD or £ 15 Pounds Sterling). This may last you as long as a month depending upon your dosage requirements.
Depending upon how much DCI you order at once, the price may be as little as $1.22 per gram, or $1.52 per 1200 mg dose.
So now that we’ve ascertained that DCI is definitely a beneficial nutrient to include in your diet, how do you get your hands on it? It is not the easiest thing in the world to find reliable scientificallly validated information pertaining to DCI and pinitol, especially upon which foods contain them and how much of which one! Essentially, the best food sources for DCI/pinitol are buckwheat, soy lecithin, chickpeas & carob (which contains pinitol).
Of those, the buckwheat is the only one that I can provide referenced DCI values for. Minndak, a processor and supplier of specialty crop food ingredients, lists neutraceutical values for DCI content per 100gm as follows:
Farinetta (a trademarked product described as being a finely granulated mixture of the aleurone layer of the hulled seed and the seed embryo, the richest parts of the seed) contains 1371 mg.
Groat (being the hulled seed) contains 287 mg.
Fancy Flour (described as being the inner endosperm excluding the hull, aleurone layer, and embryo) contains 143 mg.
Supreme Flour (described as containing a ‘certain percentage’ of the hull and endosperm) contains 384 mg.
Grit (described as being coarsely granulated groats) contains 64 mg,
Why the Grit and Groat products don’t have the same quantity of DCI in them if they are essentially the exact same product, processed differently is unfortunately beyond me. Also, they don’t provide the amount present in the whole seed, which is what is generally available to those residing outside the US, who don’t want to pay $120 in shipping for a packet of buckwheat farinetta.
From the Minndak website:
“Fagopyritols are specific carbohydrate compounds, first identified in buckwheat and named after the Latin name of this crop. Fagopyritols are mono-, di-, and trigalactosyl derivatives of D-chiro-inositol that accumulate especially in the embryo and the aleurone tissues of buckwheat. Among the plant sources, buckwheat is the richest in these carbohydrates. It has been reported that the bran milling fractions may contain 2.6g of fagopyritols per 100g of dry weight, whereas dark and light buckwheat flours contain 0.7g and 0.3g/100g , respectively. Published literature indicates that D-chiro-inositol could positively affect the blood glucose level and insulin activity (Fonteles et al, 1999, 2000; Ortmeyer et al 1993). Work done at the University of Manitoba (Kawa et al, 2003) has shown that buckwheat extract could be equally efficient in lowering blood glucose level and activating insulin as synthetic D-chiro-inositol. There is also evidence that D-chiro-inositol can help to control development of polycystic ovary (Nestler et al, 1999). However, the fate of fagopyritols in the human digestive system as well as the amount necessary to consume to achieve beneficial effects remain unknown and require further investigation.”
I have compiled the following table from various sources I have found on the internet, however, I have not been able to scientifically validate the information contained in it. On the other hand, neither have I been able to find scientific information invalidating it. Hopefully as time goes on and more interest develops in DCI, more research will be undertaken and this kind of information will be more readily available. In the interim, I provide this largely unvalidated table for general interest for those attempting to obtain a therapeutic dose of DCI or pinitol from food sources. The cells that are blank represent information I have come across indicating that those foods contain some DCI or Pinitol but for which I have not been able to quanitify the amount present.

Where Can I Buy DCI Supplements?
There are 3 places retailing DCI at the moment, however it is prohibitively expensive at the moment, so please do your research.
We are now selling DCI at the cheapest price ourselves. Our DCI is available in 18 gram packets of 100% pure powder for only $25 USD, which works out at USD$1.39 per gram or USD$1.67 per 1200 mg dose.
Chiral Balance have three different bottle sizes, a 30, 60 and 240 capsule lot. They range in price from $3.33 per 1200mg dose if you buy the small 30 capsule bottle to $2.67 if you buy their 240 capsule bottle, which will set you back $320 USD.
dchiroinositol.com sells bottles of 60 capsules of 300 mg each. Their new pricing equates to $2.66 per 1200mg dose
