The Worst Vitamins for Your Leg Circulation

You don’t have to eliminate vitamin K foods like leafy greens, but consistency is key. Sudden spikes in intake can disrupt circulation balance.

3. Vitamin B6 and B12 – The Hidden Imbalance
These two vitamins are essential for nerve and blood cell health, but too much B6—especially from supplements—can cause nerve irritation or damage over time. The result? Tingling, numbness, and a “pins and needles” feeling in your legs.

Meanwhile, high-dose B12 without a real deficiency may thicken your blood slightly, reducing oxygen flow. Your body typically excretes excess, but chronic over-supplementation can still upset balance.

Getting these nutrients from food—like eggs, salmon, or legumes—keeps levels safe and stable.
