Is iron deficiency keeping you from sleeping at night?
If your legs tend to tingle or twitch at night, keeping you awake, it may be that a lack of iron causes your brain cells to send mixed up signals telling your legs to move.
Ask your doctor to run a blood test to check your iron levels. If you have an iron deficiency, add more iron rich foods such as beef and leafy greens to your diet. Oysters and multi-vitamins are good for this also.
