Run Smarter AI Assistant: Access personalized, research-based answers to your running and rehab questions. This tool integrates Brodie’s database of research papers and podcast episodes for tailored advice.

In this episode, Brodie explores the latest research on vitamin D and its role in tendon health, diving into a 2024 comprehensive review that examines both cell-based and animal studies. You’ll learn how vitamin D influences tendon healing, inflammation, and collagen production—and how low levels could delay your recovery. Plus, Brodie shares practical advice on vitamin D testing, optimal levels, sun exposure, supplementation, and the potential role of vitamin K2.

🧠 What You'll Learn:

• How tendons respond to training and stress via collagen synthesis
• Why vitamin D is like a “site manager” during tendon repair
• The difference between in vitro (lab) and in vivo (animal) studies
• What research shows about vitamin D deficiency and tendon healing
• The importance of maintaining adequate vitamin D levels (and what’s considered optimal)
• Whether supplementation is necessary—and how to combine it with vitamin K2

🧪 Research Highlight:

Study: Exploring the Impact of Vitamin D on Tendon Health: A Comprehensive Review (2024)

• 14 studies analyzed: 5 in vitro, 9 in vivo (mostly animal models)
• Key takeaway: Vitamin D deficiency may impair tendon healing and increase re-injury risk

🛠️ Practical Takeaways:

• Ask your GP for a 25-hydroxyvitamin D blood test
• Aim for blood levels between 75–125 nmol/L for optimal musculoskeletal health
• Get sun exposure for 10–30 mins/day (arms and legs, mid-morning or afternoon)
• Include dietary sources like fatty fish, egg yolks, and fortified foods
• Supplement with 1,000–2,000 IU/day if needed; higher doses may require supervision
• If supplementing long-term, consider pairing vitamin D with vitamin K2 to support bone health and calcium balance

🎯 Ideal For:

• Runners and athletes recovering from tendinopathy
• People looking to optimize tendon repair and performance
• Anyone curious about the role of micronutrients in injury recovery
