Reasons to Take Red Ginseng on an Empty Stomach

Taking red ginseng on an empty stomach helps maximize absorption and enhance its effectiveness. Here’s why it is recommended:

Increased Absorption of Saponins
The main active compounds in red ginseng, ginsenosides (saponins), can be broken down by stomach acid. When taken after meals, food remains in the stomach, leading to increased digestive enzyme secretion, which may hinder the absorption of saponins.
On an empty stomach, stomach acid levels are relatively lower, allowing for better absorption in the small intestine.

Faster Effects
If you want to quickly experience the benefits of red ginseng—such as immune system support, fatigue recovery, and improved blood circulation—taking it on an empty stomach is ideal. Especially in the morning, it can help boost energy levels more effectively.

Maximized Blood Sugar Regulation Benefits
Red ginseng may help regulate blood sugar levels, and consuming it on an empty stomach can further enhance insulin resistance improvement effects.
A recent study showed that in a group that consumed red ginseng, postprandial blood sugar levels decreased by 11.3%, fasting blood sugar levels dropped by 9.1%, and insulin secretion index improved by 45.6%. These findings suggest that red ginseng can have a positive impact on blood sugar management.
