After doing a lot of research I decided on purchasing this product because Ester-C has a higher absorbency rate than regular vitamin C, and does not make your stomach as acidic as other products. Also, it has healthy citrus bioflavonoids. According to Livestrong.org,, citrus bioflavonoids help lower cholesterol and triglyceride levels; they make skin more resilient; they have the potential of helping with drug resistant cancer cells making them more sensitive to Chemotherapy; they could protect the brain against Alzheimer's disease; and they also might provide protection against heart disease since these type of bioflavonoids work reducing inflammation and improve circulation. The only thing I do not like about this product is the size of the tablets. They are huge and I have to cut them in half to swallow them to avoid choking. But cutting them in half is not a big deal. All in all, I highly recommend this product. Inflammation and Circulation Improvement Promising research involving patients with metabolic syndrome points to a potential benefit of a citrus bioflavonoid called hesperidin. A study published in "The Journal of Clinical Endocrinology & Metabolism" in May 2011 found that patients given hesperidin had fewer markers of inflammation in their blood and improvements in endothelial function, or the functioning of the lining of their blood cells, and thus in circulation as well. These improvements may also lower heart disease risk
