Agave Nectar: Nutrition, Fructose, Agave vs Honey and Is It Healthy?

Agave nectar, also sold as agave syrup, is a liquid sweetener made from the sap of agave plants, the same group of desert plants used for tequila and mezcal. It is marketed as a natural, plant-based swap for sugar. The USDA numbers tell a plainer story: agave syrup has about the same calories as honey, it counts as an added sugar on food labels, and roughly four fifths of its sugar is fructose, a higher fructose share than honey, table sugar or the common types of high fructose corn syrup. Below is agave nutrition per teaspoon, how agave compares with honey and sugar, what the research does and does not show, and a short answer to the question many people ask: is agave healthy?

Peptide Labs does not sell agave nectar or agave products. This article is general nutrition information, not medical advice.

What is agave nectar?

Agave plants are succulents that grow across Mexico and the American Southwest. Their sap and juice have long been used for drinks: a 2025 review of mezcal describes it as distilled from fermented agave juice, alongside pulque and tequila. Agave syrup comes from the same raw material. A 2022 review in the International Journal of Environmental Research and Public Health describes agave syrup as a vegan sweetener made from agave plant sap that grew popular as a replacement for table sugar, and notes that Mexican guidelines prohibit adding any sugar or ingredient from non-agave sources to commercial agave syrup.

Purity is a real issue. A 2012 study in the Journal of Agricultural and Food Chemistry analyzed 19 pure agave syrups from three production regions in Mexico and found fructose was the main carbohydrate, averaging about 84%. The same team showed that cheaper sweeteners such as high fructose corn syrup and sucrose could be detected when mixed in, which is why authenticity testing exists for this product.

Do not confuse the syrup with two other agave products. Agave inulin is a fiber ingredient extracted from the plant; a 2026 study extracted inulin from Agave americana leaves, and a 2014 trial of agave inulin in 29 healthy adults found slight increases in bloating and gas. Our inulin guide covers that fiber. The second is the living plant, whose sap is a skin irritant (more on that below).

Agave nutrition: calories and sugar per serving

USDA FoodData Central lists agave syrup under FDC ID 170277. Per teaspoon (6.9 grams), it provides about 21 calories and 4.7 grams of sugar, which is 9% of the FDA Daily Value for added sugars. Of that, about 3.8 grams is fructose and 0.9 grams is glucose; the entry lists no sucrose. A quarter cup (55 grams) carries about 171 calories and 37 grams of sugar, about three quarters of the added-sugar Daily Value. Agave syrup has almost no fiber or protein, and the minerals in the USDA entry are tiny; maple syrup, for example, has far more potassium per 100 grams in USDA data.

Two notes on the table. Table sugar (sucrose) is one glucose and one fructose joined by a chemical bond, so it is half fructose once digested; the FDA describes the two common high fructose corn syrups as 42% and 55% fructose. Our high fructose corn syrup guide explains those numbers. The last row is the agave plant itself, a traditional food in the Southwest that USDA lists separately; it is a fibrous plant food, not the syrup.

Agave vs honey

Agave vs honey is one of the most common comparisons, and the answer is closer than marketing suggests. Per 100 grams, USDA lists 310 calories for agave syrup and 304 for honey. Both are mostly sugar and water, and both count as added sugars. The main differences:

• Sugar type: about 82% of agave’s sugar is fructose; honey’s sugar is roughly half fructose and half glucose in the USDA entry.
• Diet style: agave syrup is plant-based, which is why many vegans use it instead of honey.
• Infants: the CDC advises never giving honey to a child younger than 1 year because of botulism risk. Infants should not get added sugars of any kind under the Dietary Guidelines.
• Taste and use: agave is thin and pours easily into cold drinks; honey has stronger floral flavors that vary by source.

Our honey and table sugar comparison covers honey labeling and the honey research in more depth, and our guide to brown and white sugar shows how little the minerals in less refined sugars add up to per serving.

Is agave healthy? What the research shows

Agave is often sold as low glycemic. That idea rests mainly on its sugar profile, since most of its sugar is fructose rather than glucose. A label claim about blood glucose is not the same as a healthier sweetener, though, and direct evidence on agave syrup is thin:

• Mouse study (2014, Journal of Medicinal Food): the authors noted that agave nectar is often promoted as a low glycemic alternative to sugar but that little research exists in animals or humans. In their 34-day study of 18 male mice, the agave group gained less weight and had lower glucose and insulin than the sucrose group, with no differences in cholesterol or triglycerides. Mouse results do not transfer directly to people, and the authors called for larger and human studies.
• 2022 review: the review describes agave syrup as containing minerals, vitamins and polyphenols compared with other traditional sweeteners, but concludes that more research on its effects on human metabolism is needed before health claims can be backed.
• Dietary Guidelines 2025-2030: agave syrup appears in the guidelines’ own list of added-sugar names, next to high-fructose corn syrup, honey and molasses, and the guidelines do not recommend any amount of added sugars.

So, is agave healthy? It is a sweetener, not a health food. It may suit someone who wants a vegan liquid sweetener, but it is not a free pass for more sugar, and its high fructose share is the opposite of what some people need. For lower-calorie options, see our guides to stevia and monk fruit. If sweet cravings are the issue, our sugar cravings guide covers what the evidence says.

Who should be careful with agave

• People with fructose malabsorption or IBS: low FODMAP programs count fructose in excess of glucose as a FODMAP, and USDA lists about four and a half times more fructose than glucose in agave syrup. Our low FODMAP diet guide explains how that works; a dietitian can help.
• People managing blood sugar: agave still counts as carbohydrate and added sugar. Ask your clinician or dietitian how any sweetener fits your plan, and see our low glycemic foods guide for how glucose responses are measured.
• Gardeners: the sap of living agave plants is irritating. A 2021 Contact Dermatitis report described a gardener who became allergic to the irritant sap of a variegated century plant, and a 2021 emergency medicine case described a sterile, painful knee inflammation after a stab from an agave spine. Wear gloves and eye protection when cutting the plant. These reports concern the plant, not the bottled syrup.

How to read an agave label

Check the ingredient list: a pure product lists only “agave syrup” or “agave nectar”, while blends name each syrup they contain, and organic or origin seals tell you about farming and source, not about sugar content. On a single-ingredient bottle, FDA guidance lets the grams of added sugars be left off while the %DV for added sugars still appears, often with a dagger symbol and footnote. On foods sweetened with agave, the agave sugar is counted in the Added Sugars line. For how fruit sugar differs from these syrups, see our banana nutrition guide.
