Is your diet lacking important vitamins and minerals?

Let’s be honest: we don’t always eat a wholesome diet. A little dessert or not-so-healthy snack is fine on occasion, but over the years, poor nutrition can take its toll. In addition, if you’ve been on a restrictive diet—whether to lose weight or to avoid a food allergy—you might also have put yourself at risk for vitamin and mineral deficiency. Once you know the true status of your health by taking a nutrition blood lab test panel, you can take action to eat more healthfully, or supplement, if necessary.

Why take nutrition lab tests?

  • Find out if you have any vitamin or mineral deficiencies
  • Detect any dietary imbalances so you can change the way you eat or add supplements
  • Get accurate reporting on your nutritional status that you can share with your doctor, dietitian, nutritionist, or other healthcare provider
