Washington (SmartAboutHealth) - According to a new study, IGF-1 or insuline-like growth factor 1 is not helpful in the fight against ALS or Lou Gehrig’s disease.

A study was carried out at 20 different medical centers all across the U.S. on over 300 patients to see if the growth hormone would help patients.

Past studies have had conflicting results over how effective the growth hormone could be.

This study split patients into two groups, with half receiving IGF-1 and hald receiving a placebo.

After two-years went by, the found no difference in the patients, which resulted in them concluding that the growth hormone IGF-1 does not slow the progression of ALS.

The study was published in the journal Neurology.
