$4.70 buys the same sweetness as a cup of sugar if you buy an erythritol and allulose blend. A monk fruit blend runs $6.43. The same sweetness in pure allulose costs $19.92, which is 4.2 times more than the cheapest blend. That gap is the real story here, not the marketing on any one bag.
Four names crowd the sugar-substitute shelf: stevia, monk fruit, erythritol and allulose. Only one of them behaves anything like sugar when it hits heat. Only one has a federal labeling exception written just for it. And the one most people think they’re buying pure usually isn’t. Here’s what’s in the bag, what it costs, and one health finding worth knowing before you restock. For more of this skepticism, see our greens powder claims check and our electrolyte powder sweat math.
What Should You Know Before Buying a Sugar Substitute?
I’ve sweetened coffee and baked with sugar substitutes for years, and I’ve learned to read the ingredient list before the front label. The front says what the brand wants you to buy. The list says what’s in the bag.
Is Your Monk Fruit Sweetener Really a Blend?
Swerve Granular is the sweetener most people picture when they hear “erythritol.” Check its own current label, though, and the bag turns out to be an erythritol and allulose blend, measured 1:1 with sugar. Lakanto Classic runs the same play from the other direction. Its ingredient list is monk fruit extract plus erythritol, with erythritol doing the actual bulking. Neither bag is dishonest about it, since both list every ingredient. Still, “erythritol sweetener” and “monk fruit sweetener” on a package front now routinely mean a blend rather than the pure extract the name implies.
That matters for two reasons. It’s why the price math has to use real blend ratios instead of a single ingredient’s price. It’s also why an erythritol health question doesn’t stop at products with “erythritol” nowhere in the name.
How Much Does Monk Fruit Cost Next to Pure Allulose?
Sticker price misleads here because none of these sweeten at the same strength per gram. So this comparison computes the price of sugar-equivalent sweetness: what you’d pay for the sweetening power of one cup (200 grams) of sugar. Each figure uses the maker’s own current listing, checked this week.
| Package and price | Sweetness basis | Cost per sugar-equivalent cup | |
|---|---|---|---|
| Swerve Granular (erythritol + allulose) | 12 oz, $7.99 (maker’s site) | 1:1 with sugar | $4.70 |
| Lakanto Classic (monk fruit + erythritol) | 1 lb, $14.59 (maker’s site) | 1:1 with sugar | $6.43 |
| Wholesome Allulose (pure) | 12 oz, $23.72 (Walmart listing) | ~70% as sweet, so it needs 1.43× more by weight | $19.92 |
Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
Here’s the arithmetic on pure allulose. It’s about 70% as sweet as table sugar, per the International Food Information Council. Matching a 200-gram cup of sugar therefore takes roughly 286 grams of allulose. At $23.72 for 340 grams, that comes to $19.92. That’s 4.2 times Swerve’s blend and just over 3 times Lakanto’s. Blending a high-intensity sweetener with a bulking agent doesn’t just make measuring easier. It cuts the price of the sweetness itself to between a quarter and a third.
Buy the blend if price is any part of the decision, which it almost always should be. Buy pure allulose if the baking behavior below is worth 4.2 times the price to you. For some recipes it genuinely is.
Does the FDA Count Allulose as Sugar?
Allulose has a regulatory carve-out none of the other three gets. In April 2019, the FDA clarified that allulose can be counted toward Total Carbohydrate without being declared in Total Sugars or Added Sugars. In October 2020, the agency finalized a caloric value of 0.4 calories per gram for it, a tenth of ordinary sugar’s four.
The reasoning is that the body doesn’t metabolize allulose the way it does sucrose. So it doesn’t raise blood glucose the same way either. That’s why a product sweetened with allulose can legally print “0g added sugar” on the front while still pouring, browning and measuring like the real thing. Stevia, monk fruit extract and erythritol don’t carry that label exception. They just happen to contain few or no calories on their own.
What Did the 2023 Erythritol Study Find?
A Cleveland Clinic team led by Dr. Stanley Hazen published the study in Nature Medicine in February 2023. It followed roughly 3,000 people across the U.S. and Europe. People in the highest quarter of blood erythritol levels were about twice as likely to have a cardiovascular event as people in the lowest quarter. Events here meant heart attack, stroke or death. In lab and animal testing, the same team found erythritol made platelets more likely to clot. Healthy volunteers who drank an erythritol-sweetened beverage saw their blood levels spike roughly 1,000-fold and stay elevated for days. The NIH’s own research summary covers the study in detail.
This is an association found in observational data plus lab mechanism work. It isn’t a randomized trial proving erythritol causes heart attacks in anyone who eats it, and this page isn’t the place to resolve that. Here’s the practical point. Erythritol shows up as the bulking agent in most monk fruit and “keto” sweetener blends. So checking a bag for “erythritol-free” takes more than avoiding products with erythritol in the name. Anyone with existing cardiovascular risk factors has a real reason to raise this with a doctor before making erythritol blends a daily habit. Zero calories doesn’t mean zero consequence.
Can You Price Pure Monk Fruit or Stevia Per Cup?
Pure stevia and pure monk fruit extract are 100 to 400 times sweeter than sugar, depending on the extract. That’s why they’re sold as drops or tiny jars rather than bags. A small bottle sweetens months of coffee. Forcing that into a price per sugar-equivalent cup would mean multiplying a few drops out to a full cup’s worth of sweetness. The result is a real number, but it says nothing useful about how the product is bought or used. So it’s left out of the table above rather than published as false precision.
SweetLeaf’s SteviaClear liquid drops list for $17.99 for 4 fluid ounces on the maker’s own site. As of this check, that product page shows it sold out directly from SweetLeaf, with only a restock notification available. Pure stevia also carries a real taste tradeoff. It can leave a bitter edge, depending on the brand, that takes some buyers a few tries to stop noticing. Monk fruit extract alone is milder but is rarely sold pure at all. Check the first ingredient on the label, because you’re very likely buying a blend. The blend’s bulking agent decides how it bakes and what health considerations apply.
Buy a pure extract if you’re sweetening drinks and want the lowest cost per use by a wide margin. Skip it if you’re baking anything that needs bulk, browning or moisture. A few drops can’t replace a cup of sugar structurally, no matter how sweet they taste.
Why Does Allulose Cost More Than Monk Fruit Blends?
Chemically, allulose is the closest thing on this page to sugar itself. It’s a “rare sugar” that browns, caramelizes and holds moisture in a way erythritol and stevia blends don’t. Erythritol-heavy blends can crystallize into a gritty texture and dry a bake out. Allulose does neither, which is the whole reason cookies and caramels built on it come out chewy instead of chalky. That baking chemistry, not marketing, is what the 4.2x price premium over Swerve is buying.
The honest downsides come next. Allulose browns faster than sugar, so recipes often need the oven dropped 10 to 15 degrees to avoid over-darkening. Large servings of any sugar alcohol or rare sugar on this page, allulose included, can also cause digestive upset in people who eat a lot of it at once. Start with less than a full swap the first time you use any of these four in a new recipe.
Which Sugar Substitute Should You Buy?
On price, Swerve’s blend wins outright at $4.70 a sugar-equivalent cup. The named loser is pure allulose, at 4.2 times the cost for the same sweetness. On baking chemistry, that ranking flips. Pure allulose is the only one of the four that browns and holds moisture like real sugar, which is worth its price in cookies, caramel and ice cream specifically. On the erythritol question, no clean substitute hides in this lineup. Most monk fruit and “erythritol” products on the shelf are erythritol blends by ingredient list, so avoiding it means reading past the front label.
Pick by the job. Swerve or Lakanto suit everyday coffee, tea and baking where cost matters. Pure allulose suits the specific recipes where browning and moisture show up in the result. Pure stevia or monk fruit drops belong in drinks only, never in anything that needs bulk. And read the ingredient list before assuming any bag is erythritol-free, because the name on the front isn’t the whole story anymore.
