How Much Coffee Is Considered Moderate?
For many healthy adults, total caffeine intake of up to about 400 mg per day is commonly considered within a generally acceptable range.
That might correspond to roughly 3 to 4 ordinary cups of brewed coffee, but caffeine content varies
enormously depending on serving size, brewing method, bean type, and coffee shop.
A large specialty coffee can sometimes contain as much caffeine as several smaller cups.
Your Genetics Influence How Coffee Feels
Some people metabolize caffeine rapidly, while others process it much more slowly.
This helps explain why one person can drink coffee after dinner and sleep normally while another feels wired after a small afternoon cup.
