Rachel Roussell Copywriting Service
Freelance Health and Longevity Writer
I'm Rachel, a freelance health and longevity writer with over 10 years of experience and hundreds of published health and anti-ageing articles.
I help HealthTech and longevity brands turn complex science into clear, high-converting copy. I bridge the gap between rigorous medical research and audience trust, delivering evidence-based web copy, product descriptions, and articles.
I translate complex clinical concepts into compelling, compliant copy.
And I'm never short of words...
In the health, wellness, and longevity space, consumers are more informed and sceptical than ever. With years of copywriting experience across health, anti-ageing, and supplement projects, I craft messaging that balances scientific accuracy with clear, benefit-driven persuasion.
From research-backed supplement product descriptions and magazine features to deep-dive educational articles, I take complex clinical data and create clear, compliant content that builds customer trust and drives real results.
