It is a non-invasive assessment that helps determine your risk of iron deficiency anemia using a simple fingernail selfie to analyze the paleness of your fingernail beds. Not getting enough iron, folate or vitamin B12 in your diet may cause: • Brittle nails • Fatigue • Physical weakness • Lightheadedness • Dizziness • Pallor (Pale or yellowish skin) • Shortness of breath • Headaches • Cold hands and feet *What is a Circulation Score? is a measure of how fast your blood is moving in your fingertips. A score lower than 50 indicates poor circulation. Consult your doctor. A score between 50 and 75 indicates that circulation is borderline and could be improved. A score over 75 is normal. The majority of women and men score between 75 - 100. You may notice increases and decreases with physical activity.
