History of the Black Soybean
Black Soybean has been used in Chinese traditional medicine for more than two thousand years. The world’s oldest pharmacopeia, the “Huangdi Neijing,” lists Black Soybean to have detoxifying and circulation-enhancing effects. Soybeans come in several varieties, differentiated by the color of their seed coat (yellow, white, red, green, and black). Only the Black Soybean is used in Chinese medicine.

Raw Ingredients
Black Soybean skin, the raw ingredient in ChronoCare, include an abundance of polyphenols not found in ordinary yellow soybeans. ChronoCare is extracted from 100% natural Black Soybean skins.

Physiological Benefits
ChronoCare has a high polyphenol content (more than 58%), which is associated with physiological benefits such as improved lipid metabolism, lower blood pressure, lower blood glucose levels, improved liver function, improved vision, lower cholesterol, improved brain function, and antiretroviral effects.

Antioxidant Activity
Reports suggest that 1-2% of the oxygen absorbed by the body becomes Reactive Oxygen Species (ROS). ROS are generated by exposure to everyday environmental factors, such as UV rays, causing damage within the body. ChronoCare’s exceptional antioxidant capacity reduces this oxidative stress.

Anti-Obesity Effects
Visceral fat accumulation causes insulin resistance and a deficiency of adipocytokine secretion, which eventually develops into hyperlipidemia, high blood pressure, and diabetes. These conditions raise the risk of serious conditions such as heart disease and stroke. ChronoCare’s anti-obesity efficacy has been demonstrated in cell culture, animal, and human clinical studies.
