According to the study, mice who were given spermidine in water had better heart function, lower blood pressure, and lived longer, compared to the mice who just drank plain H2O. It was even effective in the mice who didn't receive the spermidine until later in life -- they still outlived the chumps who didn't get it. Unfortunately, Spermidine Water probably won't be making it to market anytime soon.
You do have to be choosy with your cheese, though, if you want to reap the spermidine rewards; aged cheeses, specifically those in the blue family, are the ones with health benefits.
OK, but does spermidine affect humans in the same way?
The study also observed 800 Italians, and those who ate more cheese regularly had a lower blood pressure and lower risk of heart failure and cardiovascular disease than their cheese-avoiding counterparts, more proof that cheese may be the magic elixir of life.
