Vitamin K deficiency is associated with easy bruising and bleeding. It’s also been linked to an increased risk of osteoporosis. Vitamin K helps your blood clot normally and prevents oxidative damage to your cells. To incorporate more of this vitamin into your diet, try eating Brussels sprouts, broccoli, Swiss chard, spinach, and cauliflower. Vitamin K can also be found in kale, asparagus, sea vegetables, avocados, green beans, and carrots.
