[|AI|]  Hello and welcome to Chat Doctor, Random bruising on body can occur due to many reasons. Vitamin C can cause easy bruising because of lack of collagen network to form a strong framework. Thus, a weak framework can lead to easy bruising and thus easy bleeding. Since, you are having easy bruising, vitamin C deficiency is probably the cause for it. Vitamin C supplements will help to restore vitamin C levels. Thanks and take care Chat Doctor.
