Compositions and related methods of Cissus quadrangularis plant extracts and soy albumin that improve various cardiovascular risk factors and metabolic risk factors that cause Syndrome X. In one exemplary embodiment, university studies demonstrated that a formulation of 300 mg Cissus quadrangularis plant extract, 3 mg niacin-bound chromium, 500 mg of green tea extract, 24 mg of selenium, 100 mg of soy albumin, 100 mg of vitamin B6, 0.1 mg of vitamin B12 and 0.8 mg of folic acid to obese and overweight humans daily for eight weeks provided unexpected synergistic results that improved a variety of health related factors. In particular, supplementation with the Cissus quadrangularis formula resulted in significant weight and fat loss, decreased systolic and diastolic blood pressure, decreased total and LDL cholesterol levels and triglycerides, C-reactive protein and fasting blood glucose levels, improved total cholesterol/HDL and LDL/HDL ratios, increased HDL cholesterol, serum serotonin, creatinine and urinary malondialdehyde levels, and improved fat burning mechanisms.
