404 TED-ED 维他命价值何在

Vitamins are the building blocks that keep our bodies running; they help build muscle and bone, capture energy, heal wounds and more. But if our body doesn’t create vitamins, how do they get into our system? Ginnie Trinh Nguyen describes what vitamins are, how they get into our bodies — and why they are so crucial. [Directed by Nadav Arbel, narrated by Addison Anderson]. 维他命是我们维系身体的基石，能帮我们强筋健骨，补充能量，甚至疗伤。但要是我们的身体不产生维他命，那它们又是如何进入我们的身体的呢？阮婧群讲述了维他命的本质，它们如何进入我们的身体，以及为什么它们是如此重要。
