There are dozens of reasons why vitamin C is a crucial part of our diet, from immune system strength to repair and regrowth of cells and tissues. When it comes to cardiovascular issues, specifically angina, vitamin C can also play a crucial role, although many people don’t realize it. Vitamin C can help to control your cholesterol balance to a large degree, which is important if your arteries and blood vessels are blocked for any reasons and are causing the symptoms of angina. Some of the best citrus fruits for the treatment of angina include lemon, pineapple, papaya, mango and strawberries.
