There are many reasons why antioxidants might improve energy. One possibility is that antioxidants improve the function of mitochondria, the parts of cells that produce energy. Antioxidants might also help protect cells from damage, which can make it easier for them to produce energy. Additionally, antioxidants might help improve blood flow, which could also lead to better energy levels.
What are Antioxidants?
Antioxidants are molecules that inhibit the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, which can damage cells. Antioxidants scavenge for free radicals and prevent them from damaging cells.
The body gets antioxidants from a variety of sources, including fruits, vegetables, and other foods. Some antioxidants are also produced by the body itself.
Mitochondrial Function
Mitochondria are organelles in cells that are responsible for producing energy. They do this by converting glucose and oxygen into ATP, a molecule that provides energy for the cell. Antioxidants improve the function of mitochondria by protecting them from damage caused by free radicals.
Antioxidants and Exercise
There is some evidence that antioxidants can help to boost energy levels. One study found that athletes who took an antioxidant supplement were able to exercise for longer periods of time before feeling tired (Mach, Midgley, Dank, Grant & Bentley, 2010).
One suggested explanation for this finding is that the introduction of antioxidants with redox cycling during exercise may result in improvements in physical performance.
Redox Cycling
Redox cycling is the process of transferring electrons between molecules. This process is used to create energy and to detoxify the body. Redox cycling is also used to produce and recycle antioxidants.
Blood Flow
Oxidative stress is known to play a role in the development of cardiovascular disease. Antioxidants scavenge harmful oxidants in the blood, preventing them from damaging the cells of the blood vessel wall. This may improve blood flow and reduce the risk of cardiovascular disease. Additionally, a better blood flow could lead to better energy levels, as oxygen and other nutrients are delivered more effectively to the cells.
Conclusion
While more research is needed to confirm these findings, there is some evidence that antioxidants can help to boost energy levels.
