According to the Journal of the International Society of Sports Nutrition, creatine monohydrate can be an effective supplement to increase vascularity. The organic acid supplies every cell in the body with energy, and is especially useful for building muscle. While studies show it is safe for most people, consult a doctor first.
Vanderbilt University says creatine is naturally created in the body, especially in red muscle. A person can get more creatine from meat and fish, since these are high in protein and have their own creatine levels. However, creatine levels vary from person to person. People with low creatine or who are competing as bodybuilders can use a synthetic version in the form of a creatine monohydrate supplement.
A person obtains better vascularity through a combination of diet, exercise and overall health, cardiologist Dr. John Garner says. In fact, cardiovascular exercise shows a marked difference in the appearance of vascularity, according to a study in the American Journal of Roentgenology. While supplements can help increase vascularity, exercise is still necessary, along with a high-protein diet.
According to Web MD, creatine sometimes forces kidneys to work harder to break it down. People who have kidney disease or diabetes should avoid the supplement.
