We know torrent abundance decreases during aging,

0:09.0

and a reversal of this decline through torrent supplementation increases the health span and

0:14.0

lifespan and mice and worms and health and monkeys.

0:17.0

So this means torring deficiency is a driver of aging in these species.

0:23.1

To test whether torring deficiency is a driver of aging in humans too, long-term, well-controlled

0:29.3

torrentation trials that measure human health span and lifespan as outcomes are required.

0:35.3

Why haven't these happened already? You know why, as a naturally occurring

0:42.1

substance, toering cannot be exploited through a commercial patent. You can buy pure

0:47.8

toaurine powder, literally bites a bucket, and hardly a penny per gram. So, who's

0:53.7

kind of fun studies on it? In population

0:56.4

studies, higher blood-toring levels are associated with less obesity and lower prevalence

1:00.5

of type 2 diabetes, but when put to the test, as reviewed in this 2020 meta-analyses

1:06.3

of randomized control trials, torrent supplementation had no significant effect on bloodshed control,

1:11.5

aldeal cholesterol, or body weight.

1:13.9

Though it did drop blood pressures and triglycerides a few points, at a daily dose of half

1:18.2

a gram to six grams a day between 15 days and six months, a 2024 systematic review

1:23.5

meta-analysis of randomized control trials found the same small blood pressure

1:27.8

and triglysteroides benefit as well as a small six-point drop in fasting blood sugars.

1:34.0

Though none of those few trials on people with diabetes showed that blood pressure benefit,

1:38.8

though it did help their blood sugars.

1:43.0

Touring can also slow our heart rate by three or four beats per minute, which is considered

1:47.1

a good thing.
