Best Sugar-Free Jam (2026): 5 Brands Compared by Net Carbs and Price

Sugar-free jam isn't one product — it's at least three different sweetening strategies sharing a label, and net carbs per tablespoon swing from 1g to 5g depending on which one lands in your cart. We compared five widely available brands using only what's printed on the label and manufacturer spec sheets: net carbs, ingredients, certifications, and price per ounce.

Key takeaways

• ChocZero and Good Good tie for the lowest net carbs in this roundup at 1g per tablespoon, but they get there through different routes — monk fruit and corn/chia fiber for ChocZero, erythritol and stevia for Good Good.
• Smucker's Sugar Free Strawberry Preserves lists 5g of net carbs per tablespoon, the highest in this comparison, because its label shows 0g of fiber to offset 5g of total carbohydrate.
• Polaner Sugar-Free with Fiber Strawberry Preserves is the cheapest option at roughly $0.36 per ounce and still comes in at 2g net carbs per serving.
• Nature's Hollow and Good Good both rely on sugar alcohols (xylitol and/or erythritol); the FDA has specifically warned that xylitol is toxic to dogs, so either jar is worth keeping out of pet reach.
• ChocZero's retailer listing carries a "may contain traces of nuts" cross-contamination warning — worth checking if anyone in the house has a tree nut allergy.
• None of the five jams list wheat ingredients, based on the ingredient panels we reviewed.

How we ranked these sugar-free jams

We ranked these five jams by net carbs per serving as printed on the nutrition label — total carbohydrate minus fiber minus sugar alcohols — since that's the number most keto and diabetic shoppers are actually counting. Ties were broken first by whether the jam relies on sugar alcohols (a jar with fewer additive sweeteners ranked higher) and then by price per ounce. We have not tasted any of these jams; any texture or flavor note below is labeled as either the manufacturer's own claim or a prediction based on the ingredient's known chemistry, never our own observation. Nutrition panels, ingredient lists, certifications, and prices came from each manufacturer's own product page, from netrition.com's listings, or from the retailer linked in the Buy button, current as of this writing.

Serving sizes vary slightly by brand (15g–20g, roughly 1 tablespoon), which is why we're comparing net carbs per labeled serving rather than per gram. Net carbs are calculated as total carbohydrate minus fiber minus sugar alcohols, following the same math most keto trackers use.

The 5 sugar-free jams, ranked

1. ChocZero Sugar Free Strawberry Jam

ChocZero's strawberry jam carries the lowest net carbs in this roundup at 1g per tablespoon, and it gets there without any sugar alcohols. The label lists 15 calories, 5g of total carbohydrate, and 4g of fiber per 15g serving, with soluble corn fiber (resistant dextrin) as the first ingredient, followed by strawberry, winter melon, chia seeds, and pectin. ChocZero sweetens the jam with monk fruit extract rather than erythritol or xylitol, which is part of why it can claim "no sugar alcohols" on the front label — for other erythritol-free options, see our roundup of monk fruit sweeteners without erythritol. The company's own product description credits the chia seeds with the jam's texture; chia seeds absorb many times their weight in liquid, so chemistry predicts a thicker, more gel-like set than a jam thickened with pectin alone — that's a prediction from the ingredient's known behavior, not a firsthand taste result. One caution: the retailer listing for this jar carries a "may contain traces of nuts" cross-contact warning, so it isn't the automatic pick if anyone in the household has a tree nut allergy. At roughly $0.83 per ounce, it's the second-priciest jam here.

2. Good Good Strawberry Jam (No Added Sugar)

Good Good's strawberry jam matches ChocZero's 1g of net carbs per tablespoon, but it gets there with erythritol and stevia extract instead of monk fruit or added fiber. The label shows 5 calories, 5g of total carbohydrate, 0g of fiber, and 4g of sugar alcohol per 20g serving, with strawberries (58%) listed first, ahead of water, erythritol, and stevia extract. Good Good's own product page describes the jam as more than 50% fruit, which the ingredient order backs up. Erythritol can recrystallize once a jar has been opened and refrigerated for a while, and chemistry predicts that would show up as a slightly grainy texture over time rather than the smooth set you'd get on day one — again, that's what the sweetener's chemistry suggests, not something we observed firsthand. At about $1.08 per ounce, it's the most expensive jam in this comparison, and its erythritol content puts it on the skip list for anyone avoiding sugar alcohols.

3. Polaner Sugar-Free with Fiber Strawberry Preserves

Polaner Sugar-Free with Fiber Strawberry Preserves lands at 2g of net carbs per tablespoon and is the cheapest jam in this roundup at roughly $0.36 per ounce. The label lists 10 calories, 5g of total carbohydrate, and 3g of fiber per 17g serving, with water, maltodextrin, polydextrose, and fruit listed among the first ingredients; the jam is sweetened with sucralose rather than a sugar alcohol. Because it leans on sucralose and fiber-forming carbohydrates instead of xylitol or erythritol, it sidesteps both the sugar-alcohol digestive warnings that come with the other jars and the pet-safety concern tied to xylitol specifically. It's also the most likely of the five to be sitting on a regular supermarket shelf rather than requiring an online order, which combined with its price makes it the best value in this comparison.

4. Nature's Hollow Strawberry Jam

Nature's Hollow Strawberry Jam comes in at 2g of net carbs per tablespoon, tied with Polaner, but it reaches that number with 6g of sugar alcohol (a xylitol and erythritol blend) rather than fiber. The label shows 15 calories, 8g of total carbohydrate, and 0g of fiber per 20g serving, with strawberries and water listed first, followed by xylitol, erythritol, pectin, and xanthan gum. The FDA has issued a specific consumer warning that xylitol is dangerous to dogs, triggering a sharp insulin spike and dangerously low blood sugar, so this jar is worth keeping on a high shelf if there's a dog in the house. At about $0.60 per ounce, it's mid-priced among the five.

5. Smucker's Sugar Free Strawberry Preserves

Smucker's Sugar Free Strawberry Preserves has the highest net carbs in this comparison at 5g per tablespoon, because its label lists 0g of fiber and 0g of sugar alcohol to offset the 5g of total carbohydrate. Per the official nutrition panel, a 17g serving has 10 calories, with water, strawberries, polydextrose, and maltodextrin as the first four ingredients, and sucralose (Splenda brand) as the sweetener. Polydextrose and maltodextrin add bulk and mouthfeel the way sugar normally would in a traditional jam recipe built around granulated sugar, which is likely why Smucker's markets this as tasting close to its regular preserves, according to the brand's own product page — we haven't tasted it ourselves to confirm that claim. It's also the most widely stocked of the five, showing up in most conventional grocery stores rather than requiring a specialty retailer, and at about $0.63 per ounce it's mid-priced.

Who should buy sugar-free jam (and who should skip it)

Buy it if…

• You're tracking net carbs closely for keto or diabetic meal planning — ChocZero and Good Good both list 1g per tablespoon.
• You want the lowest price per ounce and don't mind sucralose — Polaner's $0.36/oz beats every other jam here.
• You'd rather buy from a regular supermarket than place a specialty online order — Smucker's and Polaner are both widely stocked at conventional grocery chains.
• You're specifically avoiding sugar alcohols — Polaner and Smucker's both use sucralose instead of xylitol or erythritol.

Skip it if…

• Anyone in your house has a tree nut allergy — ChocZero's retailer listing carries a "may contain traces of nuts" warning.
• You have a dog in the house — Nature's Hollow's xylitol content is worth keeping out of paw's reach, per the FDA's warning.
• You're sensitive to sugar alcohols — Nature's Hollow (6g) and Good Good (4g) both use erythritol and/or xylitol at levels that can cause digestive discomfort in sensitive people if you eat more than a spoonful.
• You want the lowest possible net carbs and won't compromise — Smucker's 5g of net carbs per tablespoon is the highest of the five, so it's the one to skip for strict keto counting.

Frequently asked questions

What does "sugar free" actually mean on a jam label?

Under FDA rule 21 CFR 101.60(c), a food can be labeled "sugar free" if it contains less than 0.5g of sugar per serving — it doesn't mean zero carbs or zero calories. That's why every jam in this comparison still lists 5g to 8g of total carbohydrate per tablespoon; the carbs come from fiber, sugar alcohols, or bulking agents like maltodextrin instead of table sugar. For more on how these swaps work, see our guide to choosing sugar alternatives.

Is sugar-free jam keto-friendly?

It depends on the brand: ChocZero and Good Good both list 1g of net carbs per tablespoon, which fits comfortably into most keto carb budgets, while Smucker's Sugar Free lists 5g of net carbs because its label shows 0g of fiber to offset the total carbohydrate. Check the specific product's label rather than assuming "sugar free" automatically means keto-friendly.

Why do some sugar-free jams have more net carbs than others?

Net carbs are calculated as total carbohydrate minus fiber minus sugar alcohols, so a jam's net carb count depends on which of those two categories it uses to stand in for sugar. Polaner and ChocZero both build in several grams of fiber per serving, which lowers net carbs, while Smucker's Sugar Free relies on polydextrose and maltodextrin with 0g of labeled fiber, so its net carbs sit closer to its total carbohydrate number. Our guide to sugar alcohols in baking breaks down how each sweetener behaves.

Are sugar alcohols in jam safe to eat?

Sugar alcohols like xylitol and erythritol are approved food additives for people, but the FDA has specifically warned that xylitol is dangerous for dogs, causing a rapid insulin spike and severe low blood sugar. In people, eating a large amount of any sugar alcohol in one sitting can cause digestive discomfort, which is part of why servings on these labels are capped around a tablespoon. If you're weighing erythritol against other sweeteners for your own baking, our erythritol vs. stevia comparison covers the differences.

Can I bake with sugar-free jam instead of just spreading it on toast?

Yes, though the fillers that keep these jams smooth on toast — fiber blends, polydextrose, or chia seeds — behave differently under oven heat than a traditional pectin-and-sugar jam, so fillings in thumbprint cookies or jam-filled pastries may set softer than you'd expect. If you're building a low-carb dessert around a jam filling, our low-carb bread roundup and sugar-free chocolate chips comparison cover other pantry swaps for the same diet.
