Healthvit Resveratrol Plus With Gymnema Sylvestre 60 Capsules is a healthy nutritious vitamin supplement. Resveratrol is a powerful antioxidant that is produced by some plants to protect against environmental stresses. Perhaps the most notable producer of resveratrol is the grapevine, which produces large amounts of resveratrol in the skins of grapes to protect against fungal diseases and sun damage. Grape seed extract is beneficial for a number of cardiovascular conditions and may help with a type of poor circulation (chronic venous insufficiency) and high cholesterol. Grape seed extract also reduces swelling caused by injury and helps with eye disease related to diabetes.
