Something I think more women with PCOS should be aware of especially those of us struggling with insulin resistance is how often maltodextrin shows up in food and supplements.
For those who don’t know, maltodextrin is a rapidly digested carbohydrate made from starches such as corn, rice or potatoes. What’s interesting is that maltodextrin often has a higher glycemic index than ordinary table sugar sometimes around 85-110 compared to approximately 65 for table sugar. Pure glucose has a GI of 100.
This means maltodextrin can be broken down into glucose very quickly potentially causing a rapid blood sugar spike and a substantial insulin response, especially when consumed in larger quantities.
And yet it’s commonly used as a filler or bulking agent in supplements, including some specifically marketed towards women with PCOS and insulin resistance. I find that pretty ironic considering many of us take these supplements specifically to improve our insulin sensitivity.
But it’s not just supplements!
I have a pretty busy lifestyle, so I sometimes have to rely on premade snacks and convenient foods. I generally try to choose healthier options, especially high protein, high fiber and low sugar products. But I’ve been genuinely surprised by how often I randomly find maltodextrin in the ingredients even in foods marketed as “healthy.”
Another thing worth knowing is that maltodextrin can be present in products labeled “no added sugar”, because it’s classified as a carbohydrate rather than a sugar on nutrition labels. So just checking the sugar content isn’t always enough to understand how a product might affect your blood glucose. I remember my type 1 diabetic grandma used to binge on suger free cookies etc and was always surprised when her blood sugar became super high…. Well turns out is was because maltodextrin.
So for women with PCOS who already struggle with insulin resistance, I think this is worth paying attention to.
Now obviously the amount matters. A supplement containing 0.1 g of maltodextrin is unlikely to have any meaningful effect on blood glucose whereas a drink containing 20 g could cause a significant spike. The overall carbohydrate content, portion size and what you eat alongside it also matter.
My point is simply to check the full ingredient lists of both your supplements and your food, rather than relying on marketing claims like “healthy” “low sugar” or “PCOS friendly.”
