polygammaglutamic acid

Add 'this' to increase calcium absorption

Poly-gamma-glutamic acid efficacy
1. Increases calcium absorption
2. Increases urinary calcium
3. Improves sleep duration and quality

This is Jinny, the pharmacist.

You've probably heard from a young age that eating calcium makes your bones strong. However, calcium is not absorbed well compared to other nutrients, so it is very important to increase the absorption rate The ' Poly-Gamma-Glutamic Acid ' introduced today is a unique ingredient that helps the absorption of calcium.

Poly-gamma-glutamic acid is a mucus component found in fermented soybean foods such as cheonggukjang or natto, and has been recognized by the Ministry of Food and Drug Safety for its functionality as 'it can help promote calcium absorption in the body' . Let's take a closer look through our research.

1. Increase calcium absorption

Calcium is mostly absorbed in the small intestine. Poly-gamma-glutamic acid can increase calcium solubility in the small intestine and improve lateral cell transport of substances using the intercellular space . So poly-gamma-glutamic acid helps to increase calcium absorption.

A paper published in the Journal of the American College of Nutrition in 2007 reported an increase in calcium absorption when poly-gamma-glutamic acid was administered to postmenopausal women . 

"In postmenopausal women who received poly-gamma-glutamic acid (PGA) once, the absorption rate of calcium in the intestine was significantly increased, especially in those with below average calcium absorption efficiency. "

2. Increased Urinary Calcium

Other studies have also shown an increase in calcium absorption when poly-gamma-glutamic acid is consumed.

A paper published in the Journal of the Agricultural Chemical Society of Japan in 2003 explains that urinary calcium increased when poly-gamma-glutamic acid was ingested, which is an indicator of increased calcium absorption .

" In the case of males, 4 hours after ingestion of the test food (poly-gamma-glutamic acid), a tendency for the amount of urinary calcium to increase compared to the intake of the control food was recognized. (Omitted) Therefore, the increase in urinary calcium recognized from the intake of the test food indicates an increase in calcium absorption. It seems to indicate. "

3. Improved sleep time and sleep quality

GABA is a representative inhibitory neurotransmitter synthesized from glutamic acid. GABA promotes brain metabolism and circulation, stabilizes the mind, and induces sound sleep. Consumption of poly-gamma-glutamic acid increases the concentrations of glutamic acid and GABA in serum and brain tissue .

In this regard, in Nutrition Research and Practice in 2021, a paper was published that reported an increase in sleep time and improved sleep quality of subjects who took poly-gamma-glutamic acid and vitamin B6 supplements .

“ We found that study participants who took a dual poly-gamma-glutamic acid (γ-PGA) and vitamin B6 (VitB6) supplement had increased sleep time and improved sleep quality. ”

Today we looked at the benefits of taking poly-gamma-glutamic acid. Finally, we'll tell you about other ways you can increase your calcium absorption. Vitamin D helps the absorption of calcium in the mucosal cells of the small intestine, so taking vitamin D helps to increase calcium absorption . And calcium and phosphorus have the property of hindering the absorption of the other side when the amount of either side is high, so it is recommended to eat calcium and phosphorus in a similar ratio when eating .

I hope you have a healthy day in body and mind. It was Jinny.
