Product Insights
The Kirkland Signature Prebiotic Fiber Supplement is a wheat‑dextrin based dietary fiber product marketed as gluten‑free. It delivers 3 g of fiber per 4 g serving with virtually no sugar, fat, salt or calories, but it is classified as an ultra‑processed food (NOVA 4) and includes the additive E1400. While it can help increase daily fiber intake, its high level of processing and additive content may be a drawback for consumers seeking minimally processed supplements.
