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
