C 1000 + Bioflavonoids is the source of four remarkable ingredients: vitamin C, rosehip extract, grape seed extract and hesperidin. The formula provides 1000 mg of vitamin C. In addition to the numerous known beneficial effects of vitamin C, we would like to point out that it contributes to the normal functioning of the immune system, to the reduction of tiredness and fatigue, to normal energy metabolism and to the protection of cells from oxidative stress. In higher doses, vitamin C also helps maintain the normal functioning of the immune system after intense physical exercise (the beneficial effect is obtained with a daily intake of 200 mg in addition to the recommended daily vitamin C)! Rose hips are the fruits of the Rosa canina (wild rose) plant and are widely used in traditional medicine. The polyphenols in grape seed extract have excellent antioxidant properties!
