Research from the University of Arizona’s Health Sciences Center has confirmed that the South American superfruit maqui berry (Aristotelia chilensis) can aid the cardiovascular system and reduce blood sugar. Clinical trials found a group of antioxidants, called delphinidins, significantly reduced levels of oxidized low-density lipoprotein (LDL), or “bad” cholesterol, which is linked to atherosclerosis and other heart diseases.

The clinical research found that the delphinidins contained in the maqui berry, known as the richest natural source of the antioxidant, aid the health of blood vessels by increasing nitric oxide and decreasing platelets linked with thrombosis, the clogging of arteries that can cause strokes. The researchers also found that the superfruit may help counteract skin aging from ultraviolet radiation-B (UVB) exposure.
