Are there benefits to collagen supplements?
胶原蛋白补充剂有效果吗？
It will make your skin look dewy and fresh, your bones and nails strong, and your joints pain-free. These are the claims made by the countless manufacturers of collagen supplements that come in the form of powders, pills and creams. For that reason, it’s no surprise that collagen has become a widely sought-after ingredient in the wellness and beauty communities. But collagen’s efficacy is still pretty up in the air. Frustrated? Here’s what we know.
它会让你的皮肤看起来水润清新，让你的骨头和指甲变得结实，让你的关节不再疼痛。这是无数胶原蛋白补充剂生产商的声明，这些产品有粉状，有药丸状，还有乳霜状。因此，胶原蛋白成为健康和美容界广受欢迎的成分也就不足为奇了。但其实，胶原蛋白的功效仍然是个未知数。苦恼吗？以下是我们对胶原蛋白的了解。
What is collagen?
什么是胶原蛋白？
Collagen is “the main structural protein that forms the connective tissue throughout our body, from skin to bones, muscles, tendons and ligaments,” said Dr. Shari Marchbein, a board-certified dermatologist based in New York.
莎莉·马克拜因博士是纽约一位获得委员会认证的皮肤科医生，她表示，胶原蛋白是“构成我们全身结缔组织的主要结构蛋白，包括皮肤、骨骼、肌肉、肌腱和韧带”。
But as we age, our bodies naturally start reducing collagen production. Board-certified dermatologist Dr. Whitney Bowe described our body’s collagen as “ropes of protein in the skin.” When we’re young, the rope remains tight, but as we age, the ends begin to fray.
但是随着年龄的增长，我们的身体产生的胶原蛋白自然开始越来越少。获得委员会认证的皮肤科医生惠特尼·鲍博士将人体的胶原蛋白描述为“皮肤中的蛋白绳”。当我们年轻的时候，绳子还很紧，但是随着年龄的增长，绳子的两端开始磨损。
Does collagen work?
胶原蛋白有用吗？
Some studies show that taking collagen supplements for several months can improve skin elasticity as well as signs of aging. Others have shown that consuming collagen can increase density in bones weakened with age. But many of these studies are small and funded by companies that make the product, increasing the opportunity for bias in the results.
一些研究表明，连续几个月服用胶原蛋白补充剂可以改善皮肤弹性、延缓衰老。另一些研究表明，摄入胶原蛋白可以增加骨密度，骨密度会随着年龄增长而下降。但这些研究中有许多规模较小，而且是由生产这种产品的公司资助的，因此研究结果可能会有失客观。
So, should you try collagen?
那么，你应该试试胶原蛋白吗？
Maybe! But get ready for a very committed relationship. If collagen does work, and you’re looking for long-lasting effects, you’ll have to take supplements for the rest of your life. Why? The answer is collagenase. Our bodies are constantly producing this enzyme and it eats away at our natural collagen. So if collagen supplements improve your skin, bones and joints, you’ll need to keep taking them.
也许吧！但必须要持之以恒。如果胶原蛋白真的有效，而且你想要达到持久的效果，那你以后的余生都要一直服用这种补充剂。为什么？答案是胶原酶。我们的身体不断地产生这种酶，它会侵蚀我们天然的胶原蛋白。因此，如果胶原蛋白补充剂能改善皮肤、增强骨骼、修复关节，你也将需要一直不断地服用。
