Tag: Coffee immunity

According to the Food & Drug Administration (FDA), up to 400 mg of caffeine daily is safe for most adults, yet many still feel the need to increase their intake to get the same buzz. This raises the question: can you become immune to the effects of coffee? The simple answer is no, but your body can become tolerant to caffeine's stimulating effects, requiring more to feel the same jolt.

Studies have shown that some individuals may develop a noticeable caffeine tolerance in as little as 1 to 4 days of consistent use. This phenomenon, often mistaken for becoming "immune to coffee," is actually the body's physiological adaptation to regular caffeine consumption, requiring larger doses to achieve the same stimulating effects.
