The level of torring in the bodies of mice, monkeys, and men, and women declines with age-dropping by nearly 80% over the lifespan.

0:15.6

This is due, in rats at least, to a decline in the synthesis of torring.

0:23.0

Would there be any benefit to restoring youthful levels through Torian supplementation? After all, lower touring levels have

0:27.9

been associated with all sorts of disease conditions, of the bone, blood, eyes, heart, cancer.

0:33.4

Of course, just because there's a correlation between lower levels and disease doesn't necessarily mean that lower levels cause disease.

0:39.5

It could be the other way around, where, for example, disease leads to lower torring levels.

0:45.9

In my last video, I talked about how torin is an antioxidant in the context of inflammation,

0:50.7

so in the context of disease, more torium may just get used up. The only way to know if Torin may help is to put it to the test.

0:59.0

We know blood concentrations of Torin declines with age,

1:03.0

so to investigate whether this decline contributes to aging,

1:07.0

researchers fed Torin or not to middle-aged mice until the end of their life,

1:11.6

and Taurine-fed mice lived longer, significantly longer, like the human equivalent of

1:17.6

seven to eight years longer, and they had only started the TORN later in life in middle-aged.

1:23.6

Now, a meaningful anti-aging therapy should not only improve lifespan, but also health span,

1:30.3

the period of healthy living, so researchers then investigated the health of the

1:34.4

touring-fed middle-aged mice and found, compared to the control group, improved functioning

1:39.8

of bone, muscle, pancreas, brain, fat, gut, and immune system, indicating an overall increase

1:45.0

in health span as well as lifespan.

1:48.2

They also tried it on other species.

1:51.1

Torrean didn't make yeast live longer, but it did increase the lifespan of microscopic

1:55.5

worms, 10 percent or more increased average lifespan in middle-aged worms and mice.

2:01.5

And the mice didn't just live longer, but also healthier, with improvements in strength,
