Celebrities and health enthusiasts are raving about its beauty benefits adding it to some of our favorite dishes. Take a look. Collagen powder, the newest craze that some health advocates help keep your body strong and skin glowing. Celebrities like Jennifer aniston swear by it. What is collagen? It's one of the components of the layers of our skin. You lose a little once you hit 20, 25 years old. Reporter: How do you use it? Sprinkle the fine white powder high in protein into your breakfast yogurt or even coffee. 30-year-old Suzanne zapella decided to use it after discovering it in other social media feed. It talked about being high in protein and being good for your gut health and skin and as a 30-year-old those are all important things to me. Reporter: Every morning for the past nine months Suzanne puts a scoop in her coffee and while she says she's noticed the most improvement in her sometime health she says the benefits go beyond that. Even though I'm fairly young I've noticed over the course of several months my skin has looked brighter. I've had small fine lines that have appeared to even out. Reporter: It can cost from $10 to $50 a jar but doctors stress there are other better ways to preserve your collagen. Eat well, get enough sleep, don't smoke and make sure to use sunscreen every day. Would you recommend topical before you would have someone ingest it? I absolutely would. Why? Because I'm putting it directly where I want it. That's how I think of it. If you take it in by mouth you might get it where you want it or it may fill in in other areas in your body where you have collagen. Reporter: As for Suzanne she says she plans to keep using it for now. The days I feel like, yeah, I want a doughnut I might have a doughnut because I know I'm doing all these other things to improve my health. Reporter: For "Good morning America," linsey Davis, ABC news, New York. Thanks, linds. I'm joined by Dr. Whitney Bowe. You are in the office. Do you see a difference with people who use it? It takes a lot for me to get excited about something and this, I am getting pretty excited about it. That makes me happy. Still relatively new but there are real studies, real evidence showing by taking ingestible collagen, collagen you te by mouth can make a difference in your overall health and the health of the skin and so easy. I mean my patients literally take a scoop of the collagen powder and just stir it into their coffee and mix it into their yogurt. Does it taste funky. It stirs in easily and sort of flavorless so makes into whatever you use it for. It's new, right? So buyer, beware. You got to look for grands reputable and have solid science behind it. Anything that can turn back the clock, but does it do anything else for your body? What else does it do? It does. So when you think about collagen, it's not just about the skin, when you ingest collagen by mouth your body breaks it down into its building blocks and your body determines where it's going to send those building blocks and how it's going to use them. When you ingest collagen it could end up impacting your bones, muscles, joints, ligaments and skin. Sounds like all positives to me. So far lots of positives, you know, it's still pretty early but if you're looking for more of a local effect or have a problem area I would say look for creams and serums that contain an ingredient called peptides because peptides when you rub them into the skin they're going to boost collagen in that specific spot. Are these the ones you don't use if you're getting -- They don't make you sun sensitive. We have fruit here wondering where does diet play into. What you put into your body impacts joufr overall health and you need vitamin C to produce collagen. Your body requires it to make collagen so you want to look for deeply colored fruits and vegetable, things rich in vitamin C, take home message, eat your fruits and veggies every day. Dr. Whitney Bowe, we thank you so much.
