Weight Loss Medication -- Not TRIMSPA -- Found in Anna

Among the list of drugs Anna Nicole Smith took in the days leading up to her death was a growth hormone -- making it the third weight loss product Smith had taken during her reign as TRIMSPA spokesperson.

A press release issued today by Dr. Joshua Perper says that before she flew to the United States from the Bahamas, Anna had taken medications that included "Growth hormone, an alleged 'longevity'/weight reducing medication."

The Broward County Medical Examiner also released a description of the contents of Anna's hotel room at the Seminole Hard Rock Casino, in which Seminole detectives found Slim-Fast on her night table. Days after her death, TMZ obtained exclusive photographs of the inside of Anna Nicole's refrigerator, which contained several cans of the diet drink.

As you may recall, Anna credited TRIMSPA for her incredible weight loss. Now that she's been connected to TWO other weight loss supplements, it's impossible to determine if TRIMSPA alone was responsible for Anna's rapid shrinking.

The Medical Examiner's office ruled today that Anna Nicole's death was ruled an "accidental overdose."

Calls to TRIMSPA were not immediately returned.
