L-精氨酸（碱基）是一种必需氨基酸（必需=人体无法合成，需要从食物/膳食中获取），尤其在身体处于压力或应激状态时。它是蛋白质的主要成分。它可以通过血脑屏障（补充剂中为游离态），并刺激垂体前叶释放生长激素。
L-Arginine (base) is an essential amino acid (essential = cannot be made by the human body and needs to be acquired from food/diet) especially when the body is under stress or duress. It is a major component of proteins. It can pass the blood/brain barrier (in supplement, free-form) and stimulates growth hormone release by the anterior pituitary gland.
