genetics, medications, pregnancy, health conditions, and how accustomed they are to caffeine.
For healthy adults, many health authorities consider up to around 400 mg of caffeine per day to be an amount that is generally not associated with negative effects for most people. But individual tolerance can be considerably lower.

Listen to Your Body
Coffee doesn’t have to be completely avoided simply because it affects some people differently.
The most useful approach is to pay attention to your own response.
If coffee regularly causes insomnia, anxiety, uncomfortable heart sensations, digestive problems, or other symptoms, reducing your intake may be worth trying.
And if you have a medical condition or take medication that could interact with caffeine, speak with your doctor or pharmacist before making major changes.
