Functional Nutritionist Specializing in Bloating, Constipation, IBS & Hormone Imbalance
Feel seen, supported, and symptom-free—with a proven system that addresses the root of your gut and hormone struggles.
You don’t need another elimination diet or random supplement.
You need someone who sees the whole picture and helps you actually heal.
I’m Leah Barack—functional nutritionist, gut health expert, and passionate about nervous system support, hormone balance, and helping women get rid of gut symptoms and enjoy food again without fear or restriction.
My work is for you if you’re ready to feel better and you’re tired of:
Constant bloating, no matter what you eat
Living in fear of food or your own body
Chronic constipation or unpredictable digestion
Feeling confused about what to eat or which supplements (if any) you actually need
Being told IBS is just something you have to live with
Hormonal symptoms that no one’s explained or connected to your gut
Healing your gut changes everything — digestion, hormones, energy, even your relationship to yourself. You don’t have to figure this out alone.

"So thankful I discovered Leah! She has been so helpful and knowledgeable in guiding me through my digestive issues. I’ve dealt with bloating for decades now and no one has ever helped me so much, listened to me so well and been knowledgeable enough to navigate all the possible causes. I’ve never felt so much symptom relief and been so empowered to seek treatment and healing. Leah is a true gem and will meet you wherever you’re at. She’s realistic in her plans and goals and emphasizes progress over perfection. I highly recommend Leah!"

“I absolutely LOVED working with Leah! She created a personalized, holistic approach to address the issues that I was experiencing and needed help with. This approach helped me get to a place with greater understanding of my hormones, nutrition, and overall health, and ultimately it led me to feeling better than I’ve ever felt! In addition to the knowledge and expertise provided, Leah was kind, compassionate, supportive, incredibly responsive, and professional. Highly recommend!”

“Working with Leah has been such a pleasure! Not only is she super kind, but she is SO knowledgable and I love her holistic approach. I have a very complex health history, and Leah has been wonderful in looking over and explaining my labs, as well as recommending additional testing-- She is the reason I got my SIBO diagnosed!
As someone who has had a lot of medical trauma with traditional western medicine, I was yearning for someone to look at me like a whole person. I have been in and out of doctors offices over and over again over the years, and so many things were not mentioned to me! I am always coming up with new questions or ideas, and Leah is so communicative in her responses.
I HIGHLY recommend working with Leah at Grace Functional Nutrition if you are looking for a new approach and a caring practitioner!” -

"Very professional, extremely knowledgeable, kind, patient, and compassionate. I couldn’t have asked for anyone better to work with on my nutrition journey. With Leah’s help I was able to significantly reduce inflammation, repair my gut, increase energy level, and generally feel sooo much better on a daily basis. Working with Leah was one of the best things I’ve ever done for my health and self-care. Highly recommend."
What my clients say:
"NO MORE BLOAT!!!"
“I’ve been feeling great and pooping very regularly!”
"Energy levels are really high, got my period on time!"
“I had a 25 day cycle which hadn’t happened for ages and I was virtually PMS free. Most notable I had no multi day migraine and no sore breasts. I also emotionally couldn’t believe how balanced I felt. Normally for more than a week before my period I fell like a monster and my level of mood swings like like 11/10. This cycle was like a 2. I have felt human.”
“I feel delightful, if anything I worry it’s too good to be true.”
“My energy, focus, and mood have drastically increased since starting your program, and from my last appointment planning healthy meals is much easier to execute.”
