The general recommendation is to keep it under 200 MG a day, the timing matters too. Having a small cup early morning and another 12 hours later, around 6:30 pm, should be absolutely fine for most people. It allows your body enough time to process the caffeine and prevents potential sleep disturbances. However, individual sensitivity varies, so listen to your body in order to figure out
how much coffee you should drink. If you feel jittery or have trouble sleeping, it might be worth adjusting the timing or quantity.
