Caffeine can have a range of beneficial effects when used in moderation. It can improve alertness and focus, improve physical performance, and reduce fatigue. Caffeine can also help to improve mental performance, increase reaction time, and improve memory recall.
Caffeine also has antioxidant properties, which can help protect against cellular damage from free radicals. It may also help to reduce the risk of some chronic diseases, such as type 2 diabetes, Parkinson’s disease, and liver disease.
What Are The Side Effects Of Too Much Caffeine?
Consuming too much caffeine can cause a range of unpleasant side effects, such as headaches, jitters, restlessness, and difficulty sleeping. Consuming more than 400 mg of caffeine per day can also lead to caffeine overdose, which can cause symptoms such as nausea, vomiting, and rapid heartbeat.
Caffeine can also interfere with certain medications, such as blood pressure medications, antidepressants, and asthma medications. It can also worsen certain medical conditions, such as anxiety and depression.
