Circulation evidence brief
Horse chestnut seed extract is commonly used for leg heaviness, swelling, and chronic venous insufficiency symptoms. It is a circulation supplement, not a general performance enhancer.
Standardized horse chestnut seed extract may reduce symptoms of chronic venous insufficiency, but it is not a general circulation supplement.
Cochrane review found short-term symptom and leg-volume improvements, but evidence quality and long-term certainty were limited.
Research typically uses standardized seed extracts with defined escin content; raw horse chestnut is unsafe and not equivalent.
Leg swelling, pain, skin changes, or suspected clot symptoms need medical assessment. Safety and medication interactions matter.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
