Colleen and her team are amazing. She's voted Austin's top nutritionist for a reason. She's deeply current on what's actually working...functional nutrition, gut health, hormones, not the outdated advice you get everywhere else. If you're in Austin and serious about your health, Colleen is the person you want in your corner.

I came to Nutritional Zest because I knew I could feel better than I did — and I knew something was off. I wasn’t “sick,” but I was tired, irritable, had low energy, and just didn’t feel like myself.

I started working with Colleen at Nutritional Zest because I knew something was off. My energy, mood, and memory weren’t where they should’ve been, I was dealing with brain fog that affected my performance at work, and by the end of every day my stomach hurt so badly I was just trying to get through it.

Nutritional Zest and Colleen…..THANK YOU! I actually have a background in Exercise and Nutrition, but Colleen is on another incredible level! She is very smart and passionate about helping people, and borders on geeky (that’s a compliment!) with the deep dive on information. She helped me tune into something that my doctors and multiple dermatologists missed or ignored. If she doesn’t have an answer, she’ll read, research, and find one! In my case, she knew where to direct me right away. Thanks again!

I’ve been working with Colleen for a year now, and it’s truly been an incredible experience. She brings so much knowledge to every conversation and has a way of sharing it with kindness, patience, and compassion. There’s never any judgment—just thoughtful feedback, positive ideas, and steady support. I’ve felt completely seen and understood throughout this journey, and I’m so grateful for her guidance. Highly recommend!
