FAQ
Is coffee dehydrating?
No. While caffeine has a mild diuretic effect, the water in a cup of coffee more than offsets this, making it hydrating overall.
How much caffeine is in a typical cup?
An 8-oz (240ml) cup of brewed coffee contains about 80-100 mg of caffeine, though this varies by bean type and preparation method.
Is it okay to drink coffee on an empty stomach?
For some, the acidity and stimulant effects may cause digestive discomfort or jitters. Having it with or after a meal can be gentler.
