A study by Djordjevic B. (2012) found that daily astaxanthin supplementation in young individuals who practised daily physical activity resulted in a reduction in markers of muscle damage and oxidative stress after training.<\/p>\n\n\n\n

Thirty-two male football players were randomly selected to take part in the study and after 90 days it was found that the astaxanthin supplementation<\/a> can prevent exercise-induced free radical production and the depletion of the group's non-enzymatic antioxidant defence.<\/p>\n\n\n\n

What is oxidative stress?<\/strong><\/h2>\n\n\n\n

The uncontrolled production of free radicals and the lack of antioxidants<\/a> to neutralise them damage molecules and alter cellular processes, which can lead to serious diseases such as Alzheimer's or Parkinson's.<\/p>\n\n\n\n

Causes of cell oxidation<\/strong><\/strong><\/h2>\n\n\n\n

The overproduction of free radicals causes cellular oxidation due to a lack of antioxidants in the body. This process is more common in sportspeople, people with a diet low in antioxidants and environmental factors.<\/p>\n\n\n\n

Sport<\/h5>\n\n\n\n

Excessive or high-intensity exercise makes the body need more energy and therefore more oxygen. This can cause cell oxidation and an uncontrolled increase in free radicals.<\/p>\n\n\n\n

Diet low in antioxidants<\/h5>\n\n\n\n

To lead a healthy life, it's very important to take care of your diet. To prevent cell oxidation, we recommend eating foods rich in antioxidants such as tomatoes, artichokes, carrots and dark chocolate.<\/p>\n\n\n\n

Environmental factors<\/h5>\n\n\n\n

Pollution, smoking, excessive sunshine, alcohol consumption and drug use are other causes of oxidative stress.<\/p>\n\n\n\n

Symptoms of oxidative stress<\/strong><\/strong><\/strong><\/h2>\n\n\n\n
Memory problems<\/h5>\n\n\n\n

Forgetfulness and memory loss are typical symptoms of people suffering from oxidative stress.<\/p>\n\n\n\n

Physical changes<\/h5>\n\n\n\n

Stiffer joints, loss of muscle strength and mobility problems.<\/p>\n\n\n\n

Cardiovascular problems<\/h5>\n\n\n\n

Cellular oxidation can cause arrhythmias and changes in blood pressure.<\/p>\n\n\n\n

Premature ageing<\/h5>\n\n\n\n

Wrinkles and spots appear on the dermis and the skin loses its usual lustre and elasticity.<\/p>\n\n\n\n
