Swollen legs and ankles—medically called edema—are often linked to salt intake, heart, kidney, or circulation issues. But an overlooked vitamin deficiency can also play a surprising role in fluid retention.
🌿 The Vitamin Often Overlooked: Vitamin B1 (Thiamine)
How It Affects Swelling
- Thiamine is essential for proper kidney and heart function, which regulate fluid balance
- A deficiency can lead to fluid buildup in tissues, particularly the legs and ankles
- Can contribute to fatigue, weakness, and heart strain
Other Vitamins That Support Fluid Balance
- Vitamin B6 (Pyridoxine) – Helps reduce water retention related to hormonal changes
- Vitamin D – Supports heart and kidney function; deficiency can worsen edema
- Magnesium – Helps maintain electrolyte balance, reducing swelling
✅ Practical Tips
- Include thiamine-rich foods: whole grains, nuts, seeds, pork, legumes
- Pair with B-complex vitamins for overall fluid regulation
- Combine with moderate exercise and reduced sodium intake for best results
💡 Bottom Line
If swollen legs or ankles persist despite limiting salt and following medications, it’s worth checking for vitamin B1 deficiency and supporting your body with thiamine-rich foods or supplements. Often, correcting this deficiency reduces fluid retention significantly.
