γ -aminobutyric acid promotes children's growth and development? How to choose the content? Is the higher the better?

I chose higher content because I am engaged in the health care industry. As many people know, after comparing many brands, I finally chose γ -aminobutyric acid from long-legged deer. The reason for this is the following：

The content of 1.500mg is the highest value in the safety range stipulated by the US Food and Drug Administration, and it is also 5~ 10 times that of similar products.

2. The purity of raw materials is greater than or equal to 99%, and Huaxi Biological Factory is the raw material, so there is no need to worry about impurities affecting health.

3. There is an invention patent in China (invention patent number: ZL201710760851,X).

4. Long-legged deer is a brand of Yishenggu that focuses on children's growth and nutrition, and it is more professional.

5. Rich ingredients, not only sleep nutrition, but also L- lysine, calcium, magnesium, zinc, endothelium corneum Gigeriae Galli, prebiotics, DHA and various vitamins. Anyone who does raiders knows that these are indispensable growth nutrition for children.

As for the effect, it is obvious that the queue of sons has changed from the first five to the back.
