Not all Vitamin C supplements are the same. Ester C® is a specialized form of Vitamin C. It is so unique it has been patented. Regular Vitamin C is acidic and can lead to stomach upset. Ester C® is non-acidic reducing the upset. The cells can more quickly absorb Ester C® leading to less lost through the kidneys. Research indicates Ester C® is absorbed up to 400% more quickly than conventional Vitamin C. In addition, Ester C®’s unique structure allows it to be retained longer in the cells themselves providing added benefit.

Vitamin C is available from a variety of dietary sources yet many people receive insufficient amounts in their diets. Several conditions can also deplete stores. Individuals with diabetes or high blood pressure often have low levels. Smoking or taking estrogen also lower levels as will long-term high stress. Low levels of Vitamin C are associated with high blood pressure, an increased risk of heart attack, and increased risk of developing cataracts. Conversely increasing vitamin C to adequate levels can help counteract these conditions. It is a common misconception that Vitamin C will prevent the common cold. While it won’t prevent a cold, Vitamin C can reduce the duration of symptoms if taken at the onset of symptoms.

Vitamin C is also a powerful antioxidant. It helps to scavenge free radicals. Free radicals are a natural by-product of normal body processes. Their presence is increased by exposure to pollutants including cigarette smoke or to ultraviolet rays. Free radicals attack healthy cells and contribute to aging and may open the door to more serious diseases.
