The cardiovascular system requires special mention as it is still the number one growing problem healthwise. While reducing dietary intake of bad fats and sugars might be helpful in supporting the health of the blood vessels and the muscle of the heart, it is essential that you attempt to reverse damage that has been done or prevent future damage from happening. The circulatory system comprises the heart and blood vessels which carry nutrients and oxygen to the tissues of the body and removes carbon dioxide and other wastes from them. Cardiovascular diseases affect the heart and blood vessels. Supplementation is an important part of cardiovascular support.
