High Caffeine Intake And Muscles Damage

Rhabdomyolysis is a very serious condition in which damaged muscle fibers enter the bloodstream, leading to kidney failure and other problems.

Common causes of rhabdomyolysis include trauma, infection, drug abuse, muscle strain and bites from poisonous snakes or insects.

In addition, there have been several reports of rhabdomyolysis related to excessive caffeine intake, although this is relatively rare (26Trusted Source, 27Trusted Source, 28Trusted Source, 29Trusted Source).

In one case, a woman developed nausea, vomiting and dark urine after drinking 32 ounces (1 liter) of coffee containing roughly 565 mg of caffeine. Fortunately, she recovered after being treated with medication and fluids (29Trusted Source).

Importantly, this is a large dosage of caffeine to consume within a short period of time, especially for someone who isn’t used to it or is highly sensitive to its effects.

In order to reduce the risk of rhabdomyolysis, it’s best to limit your intake to about 250 mg of caffeine per day, unless you’re used to consuming more.

Summary: People may
develop rhabdomyolysis, or the breakdown of damaged muscle, after they ingest
large amounts of caffeine. Limit your intake to 250 mg per day if you’re

uncertain of your tolerance.
