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

Sugar-free jam isn't one product. At least three different ways of sweetening share the same label. Net carbs per tablespoon swing from 1g to 5g, depending on which jar lands in your cart. We compared five widely available brands. We used only what's printed on the label and on maker spec sheets: net carbs, ingredients, certifications and price per ounce.

Key takeaways

• ChocZero and Good Good tie for the lowest net carbs here, at 1g per tablespoon. They get there in different ways. ChocZero uses monk fruit plus corn and chia fiber. Good Good uses erythritol and stevia.
• Smucker's Sugar Free Strawberry Preserves lists 5g of net carbs per tablespoon. That's the highest in this comparison. Its label shows 0g of fiber to offset 5g of total carbs.
• Polaner Sugar-Free with Fiber Strawberry Preserves is the cheapest option, at about $0.36 per ounce. It still comes in at 2g net carbs per serving.
• Nature's Hollow and Good Good both use sugar alcohols (xylitol and/or erythritol). The FDA has warned that xylitol is toxic to dogs. Keep either jar out of your pet's reach.
• ChocZero's store listing carries a "may contain traces of nuts" warning. Check this 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 the five jams by net carbs per serving, as printed on the nutrition label. Net carbs are total carbs minus fiber minus sugar alcohols. That's the number most keto and diabetic shoppers actually count. We broke ties first by sugar alcohols. A jar with fewer added sweeteners ranked higher. The next tiebreaker was price per ounce. We have not tasted any of these jams. Each texture or flavor note below is labeled one of two ways. It's either the maker's own claim or a guess based on how the ingredient is known to behave. It's never our own observation. Nutrition panels, ingredients, certifications and prices came from each maker's own product page, from netrition.com's listings or from the store linked in the Buy button. They were current as of this writing.

Serving sizes vary a little by brand, from 15g to 20g. That's roughly 1 tablespoon. So we compare net carbs per labeled serving, not per gram. Net carbs are total carbs minus fiber minus sugar alcohols. Most keto trackers use the same math.

The 5 sugar-free jams, ranked

1. ChocZero Sugar Free Strawberry Jam

ChocZero's strawberry jam has the lowest net carbs here, at 1g per tablespoon. It gets there without any sugar alcohols. The label lists 15 calories, 5g of total carbs and 4g of fiber per 15g serving. The first ingredient is soluble corn fiber (resistant dextrin, a type of fiber made from corn). Next come strawberry, winter melon, chia seeds and pectin. ChocZero sweetens the jam with monk fruit extract, not erythritol or xylitol. That's 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 for the jam's texture. Chia seeds soak up many times their weight in liquid. So you'd expect a thicker, more gel-like set than a jam thickened with pectin alone. That's a guess from how the ingredient behaves, not a taste result. One caution: the store listing for this jar carries a "may contain traces of nuts" warning. So it isn't the automatic pick if anyone at home has a tree nut allergy. At about $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 at 1g of net carbs per tablespoon. It gets there with erythritol and stevia extract instead of monk fruit or added fiber. The label shows 5 calories, 5g of total carbs, 0g of fiber and 4g of sugar alcohol per 20g serving. Strawberries (58%) come first, ahead of water, erythritol and stevia extract. Good Good's own product page says the jam is more than 50% fruit. The ingredient order backs that up. Erythritol can form crystals again once an opened jar sits in the fridge for a while. You'd expect that to show up as a slightly grainy texture over time, not the smooth set of day one. Again, that's what the sweetener's chemistry suggests, not something we saw ourselves. At about $1.08 per ounce, it's the most expensive jam here. Its erythritol also 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 has 2g of net carbs per tablespoon. It's the cheapest jam here, at about $0.36 per ounce. The label lists 10 calories, 5g of total carbs and 3g of fiber per 17g serving. Water, maltodextrin, polydextrose and fruit are among the first ingredients. The jam is sweetened with sucralose, not a sugar alcohol. It leans on sucralose and fiber-forming carbs instead of xylitol or erythritol. So it avoids the gut warnings that come with sugar alcohols in the other jars. It also avoids the pet-safety concern tied to xylitol. It's also the most likely of the five to sit on a regular supermarket shelf, with no online order needed. That, plus its price, makes it the best value here.

4. Nature's Hollow Strawberry Jam

Nature's Hollow Strawberry Jam has 2g of net carbs per tablespoon, tied with Polaner. But it reaches that number with 6g of sugar alcohol, not fiber. The sugar alcohol is a blend of xylitol and erythritol. The label shows 15 calories, 8g of total carbs and 0g of fiber per 20g serving. Strawberries and water come first, then xylitol, erythritol, pectin and xanthan gum. The FDA has issued a consumer warning that xylitol is dangerous to dogs. It triggers a sharp insulin spike and dangerously low blood sugar. If there's a dog in the house, keep this jar on a high shelf. 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 here, at 5g per tablespoon. Its label lists 0g of fiber and 0g of sugar alcohol to offset the 5g of total carbs. On the official nutrition panel, a 17g serving has 10 calories. The first four ingredients are water, strawberries, polydextrose and maltodextrin. The sweetener is sucralose (Splenda brand). Polydextrose and maltodextrin add bulk and body, the way sugar would in a classic jam built on granulated sugar. That's likely why the brand's product page says it tastes close to its regular preserves. We haven't tasted it to confirm that claim. It's also the most widely stocked of the five. You'll find it in most regular grocery stores, with no specialty store needed. 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 shop at a regular supermarket than order online from a specialty store. Smucker's and Polaner are both widely stocked at regular grocery chains.
• You're 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 store listing carries a "may contain traces of nuts" warning.
• You have a dog in the house. Keep Nature's Hollow's xylitol 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 those levels, eating more than a spoonful can upset a sensitive stomach.
• You want the lowest possible net carbs, with no compromise. Smucker's has 5g of net carbs per tablespoon, the highest of the five. It's the one to skip for strict keto counting.

Frequently asked questions

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

It means less than 0.5g of sugar per serving. That's the line set by FDA rule 21 CFR 101.60(c), per the FDA's guidance on "sugar free" claims. It doesn't mean zero carbs or zero calories. That's why every jam here still lists 5g to 8g of total carbs 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. That fits easily into most keto carb budgets. Smucker's Sugar Free lists 5g of net carbs, because its label shows 0g of fiber to offset the total carbs. Check the label on the jar you're buying. Don't assume "sugar free" means keto-friendly.

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

Net carbs are total carbs minus fiber minus sugar alcohols. So a jam's net carbs depend on which of those two it uses to stand in for sugar. Polaner and ChocZero both build in several grams of fiber per serving, which lowers net carbs. Smucker's Sugar Free relies on polydextrose and maltodextrin, with 0g of labeled fiber. So its net carbs sit close to its total carbs. 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 warned that xylitol is dangerous for dogs. It causes a rapid insulin spike and severe low blood sugar. In people, a large amount of any sugar alcohol at once can upset your stomach. That's part of why servings on these labels are capped around a tablespoon. 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. But the fillers that keep these jams smooth on toast act differently in the oven. Those fillers are fiber blends, polydextrose or chia seeds. They don't behave like a classic pectin-and-sugar jam under heat. So fillings in thumbprint cookies or jam-filled pastries may set softer than you'd expect.
