PGA-K Benefits & Side Effects
PGA-K is a very effective ingredient for strengthening the immune system of those with weakened immune systems. However, if you have allergies, you need to be careful when taking it. Also, if you exceed the recommended daily amount, it can adversely affect your health, so it is better to find out how to take it.

What is PGA-K?
PGA-K has the long name of potassium polygammaglutamate. As an amino acid polymer component, it is contained in a very small amount in sticky mucus such as cheonggukjang and natto, which we often eat. PGA-K is a metabolite produced by the microorganism Bacillus during fermentation. In this process, only components beneficial to immune function are separated and cultured, and 99.8% high-purity material is PGA-K.

PGA-K Benefits
If our immune cells are not activated, our body is exposed to diseases such as cancer. In addition, when the activation of NK immune cells decreases, the defense against viruses and germs decreases. Intake of PGA-K can induce anti-cancer immunity by activating NK immune cells.
Ingestion of PGA-K activates NK immune cells in the process of moving to the small intestine and binding to immune cell receptors in the small intestine mucosa. In this process, it circulates throughout the body through blood, helping to strengthen the immune function. In addition, PGA-K helps to promote NK immune cells in the small intestine and enhances immunity to help suppress bacteria, viruses, and germs. A study has shown that the antiviral component of PGA-K reduced the physiologically active substance-induced SARS virus by 65%. When PGA-K was fed to cancer-bearing mice, it was reported that NK immune cell activation was increased by 12.5 times and inhibited cancer cell growth by 32%.
Increase rate of NK immune cell activity of PGA-K
⊙ 3.3 times of Sangha mushroom
⊙ 1.5 times of ginseng extract
NK immune cell activity
20's | 60'S | 80'S | |
Activity(pg/ml) | 800 | 400 | 250 |
Rate | 100% | 50% | 30% |
PGA-K is an essential substance that helps to activate immune cells and promote overall health. One study found that NK immune cell activity increased by 52% when PGA-K was consumed.
