AgingSOS™: TAC and ROM dual test

Measure your oxidative stress and antioxidant capacity

High oxidative stress is a root cause of aging and disease over time, but it is manageable with lifestyle choices. Find out what you can do to reduce oxidative stress and raise antioxidant capacity.



Antioxidants prevent oxidative stress by neutralizing harmful excessive free radicals. Oxidative stress can cause DNA damage that could lead to aging and age-related diseases such as cancer. Having optimal amounts of antioxidants can prevent DNA damage caused by oxidative stress, and thus slow aging and lower your risk of developing age-related diseases. Optimal antioxidant levels also improve immune function and increases healthspan.

Our total antioxidant capacity (TAC) test measures the ability of the blood to blunt the harmful effects of oxidative stress. Although it does not include all of the body’s antioxidant defenses like intracellular enzymes such as superoxide dismutase, it provides a valuable measure of a person’s antioxidant capacity that can be used to identify antioxidant deficiencies and to guide to optimal levels.

The d-ROMs test measures reactive oxygen metabolites (ROMs) which are a marker for oxidative stress. Oxidative stress is a physiological condition in which cells are damaged by the oxidative substances produced by one’s own body or through environmental factors. Oxidative stress results from the imbalance between oxidants and antioxidants. It is harmful to your body because it damages your cell’s DNA, proteins, and lipids, making it one of the most important underlying causes of aging and aging-related diseases.

Risk factors for sub-optimal d-ROMs levels
  • Alcohol.
  • Smoking and pollution.
  • Radiation.
  • High fat, sugar, and low antioxidant diet.

Avoiding risk factors, getting frequent exercise, and eating a diet rich in whole, antioxidant-rich foods are the best ways to reduce oxidative stress.
