I have severe iron deficiency anemia and severe vitamin d deficiency.whenever i take iron and d3 supplements i get widespread muscle twithing.causes?

Calcium: If you are deficient in Vitamin D then you will be deficient in Calcium. When you take the Vitamin D this increases the Calcium in your system and this is likely causing the symptoms.

Take: Both can cause twitching low iron and low calcium.Calcium causes muscles to contract and magnesium causes then to relax.Studies show when magnesium intake low, calcium supplementation may reduce magnesium absorption/retention.Plus calcium supplementation can have negative effects on magnesium levels, magnesium supplementation actually improves the body’s use of calcium.

Twitching: Magnesium deficiency as well as calcium deficiency can cause this degree of muscle irritability. Discuss with your physician and get testing done.
