Oxidative stressOxidative stress is a state of imbalance within the body, where the production of harmful molecules called free radicals outpaces the body’s ability to neutralize them. It’s akin to a seesaw tipping precariously, where the reactive oxygen species (free radicals) outweigh the antioxidants meant to keep them in check.

Our bodies constantly use oxygen to fuel our cellsThe cell is the basic building block of the human body, a tiny, microscopic (too small to see without a magnifying tool like a microscope) unit that works together with billions of other cells to form every part of the body, from the skin to the heart. Each cell is… Read More. However, this process isn’t perfect. Sometimes, it creates harmful byproducts known as free radicalsImagine atoms as tiny building blocks with connectors called electrons. They prefer to pair up their electrons, creating stable structures. However, sometimes an atom loses an electron, leaving it with an unpaired one.

Our bodies naturally produce antioxidantsImagine your body’s cells as a bustling city with various activities taking place. In this city, antioxidants are like the dedicated maintenance crews that roam the streets, repairing damage and ensuring the smooth functioning of the city.

Oxidative stress occurs when the balance between free radicals and antioxidants gets disrupted, leading to an excess of these damaging molecules.
