Healthy circulation is essential to maintain proper blood and oxygen flow in the body. Normal blood flow stimulates the healthy functioning of all the systems in the body.  Certain conditions and lifestyle habits (such as arthritis, obesity, diabetes, smoking and lack of exercise) can lead to poor circulation. This in turn can lead to fatigue, muscle soreness and cramps, and a buildup of lactic acid in muscles.  There are a number of vitamins that can help support your body’s natural circulation.
