Vanadyl sulfate, also known as vanadium, is a mineral that may be involved in normal bone growth and blood sugar regulation. Most people receive approximately 6 to 18 mcg of vanadyl sulfate each day from their normal diet, Thorne Research, Inc. reports. If you have unusually low levels of vanadium in your body, your doctor may recommend treatment with vanadyl sulfate. Talk with your doctor about the warnings associated with vanadyl sulfate before beginning treatment with this type of supplement.
Adverse Effects
Treatment with vanadyl sulfate supplements may induce adverse side effects. You may experience stomach irritation, gas, nausea, vomiting, abdominal cramping or diarrhea. Additional side effects may include diminished energy, nervous system problems or green tongue discoloration, RxList reports. If you take more than 1.8 mg of vanadyl sulfate daily, you may also be at risk of developing kidney or liver damage. Symptoms associated with kidney or liver damage may include skin discoloration, frequent urination, back or abdominal pain, severe fatigue or itchy skin. Consult your doctor immediately if you experience severe or persistent adverse effects while taking vanadyl sulfate to ensure you receive appropriate care.
Health Complications
Talk with your physician about any pre-existing health conditions you have before you begin treatment with vanadyl sulfate. Taking vanadyl sulfate may increase symptoms associated with a current infection, low white blood cell count, high cholesterol or anemia in affected people. Vanadyl sulfate may decrease your blood sugar levels, which may induce hypoglycemia in people with diabetes. Additionally, if you have kidney disease, you should not take this supplement.
Medication Interactions
Vanadyl sulfate supplement may interact with certain medications, such as blood thinners or diabetic drugs, the University of Maryland Medical Center warns. Concomitant use of vanadyl sulfate and diabetic drugs may cause your blood sugar to drop dramatically. Symptoms of low blood sugar or hypoglycemia may include shakiness, headache, hunger or fatigue. Let your physician know what medications and supplements you are taking before you begin vanadyl sulfate therapy.
