Whether caffeine is "good" or "bad" is not a simple yes or no answer. It depends largely on how much you consume and how your body reacts to it. Here's a breakdown:
Understanding Caffeine's Effects
Caffeine, a stimulant found in coffee, tea, and other beverages, has both potential benefits and risks. The key factor is moderation.
Potential Negative Effects
Based on the reference provided, excessive caffeine intake can lead to a range of adverse effects. It's considered possibly unsafe when used long-term or at high doses exceeding 400 mg daily. Here's a look at the potential downsides:
