Siim Land: Do This to Never Be Vitamin D Deficient During the Winter
Peer-Reviewed Research
Key Takeaways
- Exercise regularly to maintain vitamin D levels during winter, as it mobilizes stored vitamin D from fat into circulation.
- Maintain a lean body composition to prevent vitamin D from being trapped in body fat and becoming unavailable.
- Prioritize outdoor activity whenever sunlight is available (even on Estonia’s 60 sunny days/year) to boost natural vitamin D production.
Notable Quotes
“Exercise mobilizes the vitamin D and also activates it, which is the key here.”
Bottom Line
Exercise consistently and stay lean to avoid winter vitamin D deficiency—your body can access stored vitamin D through movement even without sunlight.
