Many sugar-free ketchups are labeled “no added sugar” or “unsweetened” and rely on the natural sugars found in ripe tomatoes. Other brands avoid added sugar altogether and instead use non‑sugar sweeteners; the source examples mention monk fruit as one such sweetener.
Product details typically show very low sugar and carb counts. For example, one no‑sugar‑added ketchup lists less than 1 g of sugar per serving (versus 4 g in a regular ketchup), and another sugar‑free option lists about 2 net carbs per serving.
Unsweetened or no‑added‑sugar ketchups commonly avoid cane sugar and corn syrup (including high‑fructose corn syrup). They also often exclude added sweeteners such as honey, dates, or maple syrup and may advertise that they contain no artificial sweeteners.
Many reviewers give positive feedback, describing the flavor as excellent and comparable to traditional ketchup; reviewers also often praise the natural ingredients and the sugar‑free formulation.
Example product descriptions show substantial reductions: one listing compares regular ketchup at 4 g of sugar to a no‑sugar‑added version with less than 1 g, and another notes a no‑added‑sugar ketchup has about 75% less sugar than regular ketchup.
