Healing Properties



Lung Health

Grape seed extract has been shown to increase the content of glycogen (a form of energy storage, the main storage form of glucose in the body).[1]

Protects Lung Tissue

Liver Health

Extract of grape seed has the ability to reduce toxic effects on the liver.

Kidney Health

Extract of grape seed has the ability to reduce toxic effects on the kidneys.

Cardiovascular Health

Disease / Symptom Treatment

Lung Damage

Grape seed extract has an ameliorative effect against pulmonary damage.[1:2]

  • Grape seed extract has been shown to reduce the extent of lung damage.[1:3]


Grape Seed extract contains catechins which have anti-diabetic properties.[2]

Glucose Regulation

(Carbohydrate Digestion, Glucosidase inhibitor)

The Catechins and procyanidins found in grape seed extract strongly inhibit α-amylase and α-glucosidase activity (these are glucosidases required for starch digestion). The effect of this inhibition is to help reduce the flow of glucose from complex dietary carbohydrates into the bloodstream, diminishing the postprandial (after eating) effect of starch consumption on blood glucose levels.[2:1]

Grape seed extract strongly inhibits both α-amylase and α-glucosidase activity, with equal and much higher potency, respectively, than acarbose (a pharmacological glucosidase inhibitor).[2:2]
