Agave syrup
Definition
What it is

Explainer
In plain language
Agave syrup, also sold as agave nectar, is a liquid sweetener made from the agave plant, the same family used to make tequila. It is often marketed as a natural or lower-glycemic sweetener because it does not spike blood sugar as sharply as table sugar. That milder blood-sugar effect comes from its very high fructose content, which can make up around 70 to 90 percent of the sugars by weight, higher than high-fructose corn syrup.
Assessment
Why it is flagged
The concern with agave is its unusually high proportion of fructose. Diets high in fructose have been associated in research with fatty liver and features of metabolic disruption, because the liver handles fructose differently than glucose. Clear Label flags agave at medium severity because its natural marketing can hide a fructose load that is higher than many sweeteners it is meant to replace. This is about the type of sugar and total intake, not a claim that agave harms everyone. Human effects depend heavily on how much you consume and your overall diet, so the honest framing is a pattern to watch. Users who track sweeteners against energy, weight, or how they feel can note agave the same way they would any added sugar.

Practical
Reading the label
It appears as agave syrup, agave nectar, agave juice, or blue agave. Watch for it in products marketed as natural or refined-sugar-free, where it is often the sweetener doing the work despite the healthy framing.
Alternatives
If you want to avoid it
Some people who want to moderate fructose choose small amounts of other sweeteners, or unsweetened versions of the same product. Because all added sugars add up, comparing labels for total sugar per serving is often more useful than the sweetener's name alone.
FAQ
Common questions
Is agave healthier than sugar?
Agave has a lower glycemic index than table sugar, so it raises blood sugar less sharply, but that is because it is very high in fructose. On total sugar and fructose load it is not clearly better than ordinary sugar.
Why is high fructose a concern?
The liver processes fructose differently than glucose, and diets high in fructose have been associated with fatty liver and metabolic changes in research. The effect depends on how much you consume overall.
Is agave more fructose than high-fructose corn syrup?
By weight, agave syrup can contain a higher share of fructose than high-fructose corn syrup. The exact amount varies by brand and how the syrup is produced.
