Welcome GSH Bio-Tech

At age of 40, do you focus on nutrients such as glutathione?

The essence of aging is not determined by genes, but rather the large amount of reactive oxygen produced by the long-term overloading of mitochondria, which damages the "cell engine" itself.

The key to health management after the age of 40 is not to simply inject glutathione directly (as it is easily broken down by the digestive system), but to provide the raw materials needed for its production, allowing the cells to synthesize it on their own.

Why is glutathione singled out among all these components?

Many people asked: "Dr. Chen, there are so many anti-aging products on the market. What do you consider the most important aspect?"

The answer might come as a surprise to many people.

It's not collagen, not vitamins, nor even NMN. Instead, it's - glutathione (Glutathione).

After studying a large number of mitochondrial literature, it was found that many age-related changes all share a common phenomenon: the amount of glutathione in the mitochondria is decreasing.

It's not because of getting old, but because mitochondria are tired.

Many people believe that aging is determined by genes.

In fact, humans do not have any so-called "aging genes".

The real issue is: As we age, our mitochondria are constantly affected by factors such as diet, stress, lack of sleep, and environmental toxins.

When mitochondria operate at an excessive level for a long time, a large amount of reactive oxygen species will be produced.

These reactive oxygen species are like the exhaust gases produced during the operation of an engine.

There is no problem when the quantity is appropriate.

However, if the cleaning ability weakens, it will start to damage the engine itself.

One of the important substances responsible for eliminating these reactive oxygen molecules is glutathione.

Glutathione begins to rapidly deplete at age of 40.

When young, the body had a strong ability to produce glutathione.

Even if one stays up late occasionally or has irregular eating habits, they can still recover quickly.

But as one gets older, this system gradually becomes inadequate.

The problem is not how much the free radicals have increased, but rather that the body no longer has enough glutathione to deal with these free radicals.

So the mitochondria were subjected to increasing pressure.

The physical decline, slower recovery, and reduced mental state that many people experience are essentially manifestations of a decline in the body's ability to manage energy.

Who should pay attention to glutathione in mitochondria?

If you fall into any of the following categories, you should pay particular attention:

Aged over 40

Often feel that physical recovery is slowing down

Under high work pressure and lack of sufficient sleep

Often eat out or consume more refined starch

Hope to make preparations for health in the next 10 to 20 years

Aging does not occur suddenly all at once.

Rather, it accumulates gradually over time through the process of consuming mitochondria in small amounts every day.

Starting with replenishing glutathione might be the simplest step in taking care of the mitochondria.
