What is oxidative stress?
Cells produce reactive oxygen species during normal metabolism. The body balances them with antioxidant enzymes and repair systems. A disruption in the balance between production and defense may be associated with damage to proteins, lipids, and DNA.
Are oxidants entirely harmful?
No. Reactive molecules take part in the fight of immune cells against microorganisms and in cellular signaling pathways. Transient oxidative signals are also important in certain exercise-induced adaptations. Therefore, the goal is not to “zero out” oxidants, but to maintain physiological balance.
Do antioxidant supplements prevent diseases?
In the general population, high-dose antioxidant supplements have not been shown to prevent cardiovascular diseases or cancer. In some cases, harm can also be seen. For example, high-dose beta-carotene may increase the risk of lung cancer in smokers; high-dose vitamin E may affect the risk of bleeding.
Food or supplement?
Foods such as vegetables, fruits, legumes, nuts, and olive oil provide fiber, vitamins, minerals, and numerous phytochemicals alongside antioxidant molecules. If there is a need for supplementation, the product and dose should be selected according to dietary patterns, medications, and clinical goals.
Our approach at our Bodrum clinic
We do not interpret the concept of oxidative stress through a single device measurement or a single “antioxidant serum.” We evaluate nutrition, smoking, metabolic risk, sleep, physical activity, medications, and, when necessary, standard laboratory findings together.
