Hi, I’m Sarah Mitchell

Former PE teacher. Joint health researcher. Living with knee OA.

Home › About

I spent 20 years on my feet as a PE teacher. My knees kept the receipts.

For 15 of those years I taught physical education in Manchester, in the UK. The last five, my own knees started handing me the same complaints I’d spent a career telling students to push through. When a doctor first mentioned surgery, I wanted to understand my options properly before agreeing to anything.

That research became JointLabPro.

I’ve since relocated to San Antonio, Texas, where I now write about what genuinely helps early osteoarthritis, from red light therapy to recovery tools to the daily habits that decide how stiff I wake up.


Why I Started JointLabPro

When I first went looking for solutions to my own joint pain, the internet was wall-to-wall generic advice and sponsored content. Everyone recommended the same handful of products without explaining why they worked, or whether the science behind them actually held up.

A PE background trains you to think in evidence. I knew how to read a study, spot a marketing claim, and recognise when a product actually earns its confident label. So I started doing the reading myself. Finding the clinical studies behind every ingredient. Comparing mechanisms rather than star ratings. Keeping notes on how my own knees responded over weeks, not days.

JointLabPro is the result. Every review here reflects real research and an honest verdict, including the products that did nothing for me, rather than a commission-chasing recommendation.

How I Review Products

My process covers four things:

  • Ingredients and clinical evidence. I read the actual studies, not just the label. If a product cites research, I find it and check what it really measured, including who funded it.
  • Real daily use. For the products I use myself, I give them the timeline the research uses, weeks rather than days, before forming a verdict. For anything I haven’t used personally, I say so and compare it on the evidence instead.
  • Real-world results. I combine my own experience with verified buyer reviews, filtering out the incentivised and unverified ones, to build a complete picture.
  • Value for money. A product that works but costs a fortune isn’t a good recommendation. I factor in price per day and the alternatives every time.

What I’ve Learned Living With Knee OA

A few things that might save you time and money:

  • Most topical creams only mask pain. Menthol products like Biofreeze work by distracting your nervous system with cold. That is different from reducing inflammation, and the distinction matters for long-term joint health.
  • Glucosamine is not the only option. The science has moved on. Undenatured Type II collagen works through a completely different mechanism, and a 2016 clinical study found it outperformed the standard glucosamine and chondroitin dose over a 180-day trial.
  • Consistency beats the product. Almost every joint supplement needs 4 to 8 weeks of consistent daily use before meaningful results appear. People who quit after two weeks never give it a fair chance.
  • Red light therapy is underrated. There is solid research behind photobiomodulation for joint inflammation. The catch is choosing a device with enough irradiance, since most cheap belts do not deliver enough energy to the tissue.
