Glutathione is one of the most common substances in the human body. It is present in almost every cell in the body. In addition, glutathione, as a small molecule active peptide in human cells, has the functions of maintaining normal immune system function, antioxidant and detoxification.
Some functions of glutathione：
If glutathione is reduced, free radicals may damage the body and accelerate the aging process and cause cognitive decline. Several studies have found that as we age, our bodies produce less of this antioxidant.
In women, its levels decrease at the onset of menopause and remain low after menopause. In older people, lower levels of increased oxidative stress can make bones more fragile, leading to osteoporosis.
Cells depleted of glutathione are susceptible to damage. Low levels trigger a cascade of reactions that ultimately lead to cell damage and death, thus accelerating aging.
2. Maintain intestinal health
People with IBS have reduced glutathione synthetase activity. They also tend to have lower levels of cysteine, its main component.
The most important enzyme involved in inhibiting free radicals is called glutathione peroxidase. This enzyme uses glutathione and requires selenium to function, removing harmful substances. High levels of this enzyme indicate higher oxidative stress that needs to be neutralized.
This enzyme also helps renew and strengthen the intestinal wall. In animals, glutathione protects the intestinal wall, which may help prevent leaky gut.
3. Protect heart health
Glutathione peroxidase, and low levels of glutathione, are associated with high oxidative stress and an increased likelihood of heart attack.
Cardiovascular diseases are primarily caused by oxidative stress in heart tissue. Glutathione reduces free radicals, which in turn may prevent stroke or heart attack.
