                                According to nutritional data, a single Kirkland Signature blueberry muffin from Costco contains approximately 71 grams of total carbohydrates. This significant carbohydrate count is primarily due to the muffin's size and sugar content, making it a less-than-ideal choice for those on low-carb diets.
