You are right on the money to assume that easy bruising can be a sign of nutritional deficiency. A deficiency of vitamin C, iron and vitamin K is usually associated with easy bruising. I would look for a vitamin C product which contains bioflavonoids, like Ultra C 1000 by Metagenics. Bioflavonoids enhance the activity of vitamin C in the body. After a few months, you will notice that the bruising will improve. I had this problem myself and it’s gone now with the use of supplements. Before taking iron, I would recommend that you see your doctor to ask for an assessment of your levels. Ferritin is the name of the test that you should inquire about. If it is discovered that you need to take iron, take iron citrate at the same time as your vitamin C. The vitamin C will enhance the absorption of iron and the citrate form is non-constipating. Also, in any case of easy bruising, you want to ask your doctor for a complete blood count (CBC) to ensure your platelet levels (clotting factors) and level of red blood cells are normal.
Vitamin K should not be taken if you have a history of an increased risk of blood clotting or if you’re taking blood thinning medications. If you are free and clear of these risk factors, adding chlorophyll to your water each day can be a good way to pump up your vitamin K.
