SUPPORT FOR THOSE WITH IMPAIRED GLUCOSE TOLERANCE - New research suggests increased vitamin C intake may be beneficial for those with impaired glucose tolerance. While vitamin C supplementation has not been shown to specifically influence glucose metabolism, research suggests that those with impaired glucose tolerance may have increased needs for vitamin C. BOOSTS HEART HEALTH - Making sure that you're taking the proper amount of vitamin c benefits your heart health, by aiding your body's ability to support healthy levels of triglyceride levels within the normal range. Triglycerides are a form of fat that can be found within your blood, and can pose a problem when levels spike, and LDL cholesterol can form on the walls of your arteries. Combined with a healthy diet and plenty of exercise, taking a vitamin C supplement may be the heart health boost. BATTLES FREE RADICALS - Free radicals can do a number on your body and one way to give your body the defensive support it is to make sure you're getting enough vitamin C. Free radicals can invade our bodies from the foods we eat, the air we breathe and even from the sun's rays. Fortunately antioxidants, like the ones found in abundance in vitamin c, save our cells from damage by neutralizing free radicals, potentially reducing or even preventing some unhealthy consequences.
