I am an independent researcher with 7 years of experience in academia and industry, working on diabetes, nutrition and supplementation, exercise physiology, longevity, and cancer metabolism.
📚 Literature search
📚 Systematic reviews (PRISMA)
📚 Medical data analysis
📚 Dietary supplements review
📚 Academic writing
Whatever you need to research and write about, I can help you. We can achieve great things together!
As an independent researcher, I specialize in evidence synthesis and systematic reviews across various health-related topics, including nutrition (DOI: 10.1093/nutrit/nuaf179), exercise (DOI: 10.1007/s10103-025-04318-w), and well-being. I have also advised supplement brands on the efficacy and safety of their products.
As a medical analyst, I assessed off-label therapies with potential rejuvenation effects, examining all available literature on a specific drug/supplement and writing an extensive risk-benefit analysis.
During my PhD, I investigated different approaches to improve glucose control in diabetes:
+ Islet viability assessment to improve transplant outcomes in type 1 diabetes.
+ Nutrition in hospitalized patients with type 2 diabetes using automated systems (DOI: 10.1111/dom.14187).
+ Exercise on exogenous insulin kinetics in type 1 diabetes: a clinical study (DOI: 10.1177/19322968211043915) and a systematic review (DOI: 10.1111/dom.16088).
In addition, I worked as a personal trainer and have several sports nutrition and fitness certificates, with a special interest in supplementation and ergogenic aids.

Health and wellness content doesn’t have to be boring, clinical, or confusing. It should empower, inform, and make people feel like they’re talking to an actual human who knows exactly what they need — and how to make it happen.
Hey! I'm Jennifer, a maple-syrup-loving Canadian therapist and nutritionist....
What I do:
I create interesting, engaging, and action-oriented content in the health and wellness space. From blog posts and articles to lead magnets, wellness guides, and ebooks, I simplify complex topics so your audience feels inspired to hit your “call to action” link.
With over a decade of experience as a mental health therapist, nutritionist, and health writer, I bring a deep understanding of the human body and mind. I have degrees in psychology, foods and nutrition sciences, a post-grad in counseling psychology, an ADHD Mental Health Professional Certificate (ADHD-CCSP), and a health and life coach certification. 🎓🎓Whether you need content on mental health and wellness or an expert reviewer and editor, I’m here to connect your message with readers.
My Approach:
Ever felt like health content is just facts and lacks the touch that inspires people to actually take action? Everyone already knows what they “should” do to get healthier, but knowledge alone clearly doesn’t lead to action.
I believe in content that inspires change, so I blend my science-backed knowledge with a tone that feels like a conversation — approachable, compassionate, and most importantly, full of practical tips. I don’t just write facts; I craft experiences your audience can connect with. My post-grad in Problem-Solving Brief Therapy (PSBT) really makes the difference here, where I’ve learned how to hone in on the real problem and set small, measurable, actionable goals — hitting the heart of the issue and pain a person feels. 🎓🎓
If you're ready to elevate your brand’s voice and get your clients wanting more, send me a message or invite me to your project.
What I’ve Done:
✅ Wellness Articles and Medical Writing: Crafted content for addiction centers, psychology and therapy platforms, autism clinics, mindfulness apps, nutrition and fitness sites, supplement brands, health tech companies, clinical trials, and more.
✅ Health and Education Guides: Created in-depth and science-backed guides on chronic disease, nutrition, and mental health — with compassion and actionable tips.
✅ eBooks and Workbooks: Covered anxiety, depression, habit psychology, eating disorders, diet culture, emotional resilience, hormones, gut health, and more.
✅ Course Creation: Written and filmed content for health courses on chronic disease management for women, fertility, anxiety and ADHD, neuropathy, weight management, eating disorders, general health and wellness, mindfulness, and more.
✅ Health and Medical Copywriting: Created clear, persuasive, and engaging copy for wellness websites, healthcare companies, and clinical trials. That included brochures, patient materials, and marketing content for healthcare professionals and patients, focusing on clarity and trust-building.
What Past Clients Have Said…
⭐⭐⭐⭐⭐
"Jennifer has been a joy to work with! She was easy to communicate with and has met all of our expectations. She is efficient, has great time management skills and can meet deadlines. Her work is very professional and you can clearly note her expertise. We would hire Jennifer again. :)"
— Upwork client
⭐⭐⭐⭐⭐
"Jennifer is a brilliant and professional writer. She delivered a great piece of work on time and I didn't have to edit it at all. I highly recommend her. I had planned to send Jennifer more work, but the client's plans had changed. This is the only reason why we did one short piece of content. Jennifer, as soon as things change, I will be back! Can't recommend Jennifer enough. A talented writer, great freelancer, and all-round, very easy to work with."
— Upwork client

✅ Deadline-Driven: Your deadlines matter (and I thrive on them). I pride myself on delivering high-quality content on time, every time.
✅ Expertise + Empathy: With a background in psychology and nutrition, I get the science — and I know how to translate it into something your audience will love.

"Krystie was an absolute pleasure to work with. Her accuracy, accountability, and initiative will be missed on the team. I will be keeping Krystie in mind for future initiatives. I cannot recommend Krystie enough to the Upwork community."
"Thank you for all your work Krystie. It was a pleasure working with you!"

You are here because you understand the importance of a well-translated and written document.
The fact that a bad article can destroy a company’s image and make it lose clients is something scary.
It is even worse if it is something related to health, not knowing how to define a muscle, a blood vessel or a specific nerve can make the difference between a good work and a bad one.
Being a physician with over 10 years of experience as a family practitioner and occupational health specialist, I have the experience, background, and knowledge to make your project stand out from the rest.
A good article can engage the reader, increase your sales or your target demographic and in the end, make you, my client, feel satisfied.
This is something I take very seriously since my ultimate goal is to help you, your business or company, grow.
My services include:
* Medical Writing
* Medical Translation
* General Translation
* Book Translation
* Medical Review
* Medical Research
* General Research
* Data Entry
The most important part of being a freelancer is communication, I just don’t want to meet your goals, I also want to build long-lasting relationships with everyone I work with.
And I get it, hiring a freelancer you hardly know might be something hard to do but I promise to make your project my most important one and to give you my best work possible.
If you think that my values, skills, knowledge and most importantly, experience, are a good fit for your project just hit the green button up there so we can have a talk!
