As per a report, a woman in Sweden suffered a deadly hemorrhagic stroke after a workout.

Doctors who treated the 53-year-old woman suspect that the stroke was caused by an ingredient in a workout supplement that she was taking. The ingredient could be a compound similar to amphetamine.

The woman previously reported as healthy and physically active, took a single dose of a sports supplement called Jacked Power (manufactured by the Swedish company MM Sports) shortly before she started her usual, vigorous workout in January 2014.

About 45 minutes of her workout she started feeling numbness and clumsiness in her left hand, which continued for the rest of the day.

The woman consulted a doctor and CT scans revealed that she had experienced a hemorrhagic stroke, a type of stroke in which a blood vessel bursts or leaks blood into the brain.

She recovered, and was discharged from the hospital after almost five days. Further examinations of her showed that the woman had no risk factors for stroke as she had normal blood pressure and weight. Also none of her family member had ever experienced a stroke.

Later doctors in Sweden concluded that it was more likely that something present in the supplement she took led to her stroke.

After the hearing of her case, doctors in the United States asked to test a sample of the woman's supplement for drugs that were not listed among the ingredients on the label, but could have caused the stroke.

According to the report the only drug found in the supplement was a compound called beta-methylphenethylamine (BMPEA), which is chemically similar to amphetamine.

The drug has never been tested in people before therefore heath effects of it were unknown. The findings of the report were published online today (May 11) in the journal Annals of Internal Medicine.

The new report now provides more evidence of the compound's potentially harmful effects, in that the combination of BMPEA and exercise.
