The term "antisugar natural capsule" is not a standard or widely recognized term in the context of supplements or medications. However, it's possible that it could refer to a product designed to help regulate blood sugar levels or manage conditions related to sugar metabolism, such as diabetes.

If you are referring to supplements that claim to have "antisugar" properties or promote blood sugar balance, it's important to note that specific formulations can vary, and the effectiveness of such supplements may not be universally established. That being said, some natural ingredients are commonly associated with potential benefits for blood sugar regulation. Here are a few examples:

1. Cinnamon: Some studies suggest that cinnamon may have a positive impact on blood sugar levels by improving insulin sensitivity.

2. Chromium: Chromium is a mineral that is involved in insulin action, and it is sometimes included in supplements for blood sugar support.

3. Berberine: This compound, found in several plants, has been studied for its potential effects on blood sugar regulation.

4. Bitter Melon: Bitter melon is a fruit that has been traditionally used in some cultures for its potential antidiabetic properties.

5. Fenugreek: Fenugreek seeds contain soluble fiber, which may help slow down the absorption of sugar and improve blood sugar levels.
