Michelle Hislop, TestWise Clinical Nutritionist & Founder

Hi, I’m Michelle Hislop, Clinical Nutritionist, mum of two, and founder of TestWise Clinical Nutrition.

With over 14 years of experience, I help clients understand their health when their bodies aren’t working as they should. Navigating perimenopause in my early 40s alongside work and family life gives me a deep, personal understanding of feeling tired, stuck, or out of balance.

I specialise in hormones, gut health, and genetics, using functional testing to uncover root causes and translate complex results into clear, practical steps, supported by personalised 1:1 care between appointments.

Alongside my clinical work, I’m a Bioconcepts Clinical Education Consultant. I currently see clients on two Saturdays per month and maintain a 4–6-month waitlist to ensure focused, high-quality care.

Using Practice Better, everything from bookings to messaging is streamlined so you always feel clear, supported, and guided.

If you’re ready to stop guessing and feel confident in your body again, I’d love to support you.

    “I was really struggling with perimenopause symptoms and nothing seemed to be working. Michelle took a completely different approach, using vaginal microbiome testing to uncover the root cause—I'm so grateful for her support and insight."

    Robynn - Sydney

    "Michelle is such a kind and empathetic practitioner, and her knowledge and commitment to holistic treatment shines through in every interaction. She doesn’t just give generic advice- she looks at you as an entire human system and person (not just your symptoms) to find and offer you the best care she can. After only a few months of working with Michelle, I can feel myself improving each day."

  • Happy client, drinking one of her healthy supplements.

    Casey - Brisbane

    “I felt like I had tried all of the usual avenues for finding out why my body was going into shock. I have been to the GP, gastroenterologist, radiographer, liver tests, etc, etc Every time the answer would be 'nothing', 'within range', with me just having to get by. Michelle has introduced me to a whole world of alternative ways to ensure you're actually 'well' from the inside out. To be guided to the proper test, pulling apart the results and helping me make changes in a supportive way, where I don't feel pushed or judged, especially when I struggle to stick to the plan. I've been picking Michelle's brain and making changes & adjustments to my life for nearly 10 years, with her continually showing me the correct path, and my body proving her right every time. If your health & happiness is one of your top priorities & you need help, I wouldn't hesitate to recommend Michelle."

  • Cinzia - Sydney

    “Michelle has truly been a lifesaver. Before working with her and doing the gut testing, I was at my wits end, desperate for answers about why I felt so bloated and unwell all the time, despite living a healthy lifestyle. Michelle not only gave me those answers, but patiently guided me through every step of the process - from complex protocols to countless supplements - with incredible care and clarity. A year later, and I feel like a completely different person. I am endlessly grateful to Michelle and everything she’s done for me!”

She’s helped me create a way of eating that feels easy to maintain long term. I have so much more energy, mental clarity & less bloating. Michelle has helped me with my gut & hormonal health. She’s also helped many of my clients, which I am truly grateful for.”

    Sarah - Bendigo, VIC

    “Michelle is an incredibly diligent and conscientious practitioner. She is extremely knowledgeable about gut health and without her help I may have continued to live in a toxic/mouldy environment none the wiser. Her client-centred approach meant that I felt completely supported the whole way through my treatment. Her patience and adaptability instilled hope in me that my symptoms would improve with time. Thank you, Michelle! “
