Helps to break down fat.
Naringin is most commonly found in grapefruit. Naringin is considered to be a polyphenol.
It increase the release of a protein called Adiponectin through stimulating peroxisome proliferator-activated receptors (PPAR).(16) Adiponectin helps to make losing fat easier by the regulation of glucose and oxidation of fatty acid.(17) In a studied of p-synephrine on resting metabolic rate (RMR) they found that “50 milligrams of p-synephrine alone exhibited a 65 kcal increase in (RMR)”. When they did this test again by combining 50 milligrams of p-synephrine with 600 milligrams naringin it resulted in a 129 kcal increase in RMR. Both of these studies were concluded with no increase in heart rate in blood pressure.(15)
