Is caffeine bad for you?

While it is generally accepted that moderate consumption of caffeine is safe, the effects of caffeine on an individual can vary greatly.

In large doses, caffeine has been associated with anxiety, restlessness, difficulty sleeping, and interference with absorption and metabolism of calcium [1], which can contribute to bone thinning (osteoporosis).

Caffeine can also increase heart rate and blood pressure [2][1], and cause jitteriness.

For most people, consuming up to 400mg of caffeine a day is not likely to be harmful, but everyone's tolerance is different.

Therefore, it is important to pay attention to your body and monitor your caffeine intake to ensure it is not having a negative effect on your health.

If you plan to consume caffeine, it is important to be aware of the potential side effects and to keep your daily intake within the recommended guidelines.

It is also important to be aware of the sources of caffeine, such as coffee, tea, energy drinks, and chocolate, and to be aware of the caffeine content of each product.

Additionally, it is important to note that some people may be more sensitive to caffeine and may experience more of its side effects.
