In healthy adults, caffeine intake of up to 400 mg per day has not been linked to increases in cardiovascular disease risk.[1][2] However, the evidence is uncertain regarding the long-term effects of regular caffeine intake for people with high blood pressure or pre-existing heart conditions.[1][3] This also applies to people for whom stimulants in general are not recommended. Low to moderate intake may be generally safe, but this must be assessed on a case-by-case basis in consultation with a physician.
If I have a heart condition, can I still have caffeine?

Caffeine intake of up to 400 mg per day is generally safe for adults without health conditions and is not associated with increased cardiovascular disease risk. However, people with high blood pressure or preexisting heart conditions should consult a physician to assess the safety of caffeine on a case-by-case basis.
