Chief Scientist and founder Dr. Jin-Xiong She sat down with NAD Research to discuss Jinfiniti's intracellular NAD blood spot test and the longevity effects of IV NAD+ drip and NAD precursor supplementation. NAD Research: Have you been able to observe, or have patients been able to report, improved clinical outcomes corresponding to their increased intracellular NAD...

Antioxidants prevent oxidative stress by acting as the neutralizing harmful excessive free radicals. Having optimal amounts of antioxidants can prevent DNA damage caused by oxidative stress that could lead to aging and age-related diseases such as cancer. Optimal antioxidant levels also improve immune function and increases healthspan. Our total antioxidant capacity (TAC) test measures the...

SA-β-gal is an enzyme and considered the best biomarker for cellular senescence, which is the permanent arrest of cell growth. Senescence increases as we age and is one of the most important hallmarks of aging. Senescent cells are “zombie” cell that do not work properly, thereby negatively impacting health. Senescent cells are characterized by morphological...

The liver produces cholesterol that your body needs and packages fat molecules (cholesterol, phospholipids, and triglycerides) in very low-density lipoproteins (VLDL). As VLDL transports fat to cells around your body, VLDL becomes low-density lipoproteins (LDL), the more dense particle. LDL delivers fat wherever it is needed. LDL is the “bad” cholesterol that are prone to...

Unlike the “bad” low-density lipoprotein particles (LDL) which deliver fat molecules to cells, HDL is the “good” cholesterol that removes extra cholesterol from cells and reduces plaque buildup in your arteries and carries extra cholesterol back to your liver where it is expelled. The good balance between HDL and LDL helps reduce your risk of...

Alanine aminotransferase (ALT, also known as SGPT) is one of the most widely tested liver enzymes. The other one is aspartate aminotransferase (AST or SGOT). In healthy persons, these liver enzymes are predominantly contained within liver cells and to a lesser degree in the muscle cells. When the liver is injured or damaged, liver cells...
