Measure key nutrients for those following a vegetarian or vegan diet in one convenient panel.
A vegetarian or vegan diet can be a healthy way to eat, but some key nutrients may be harder to get from plant-based foods alone. This panel measures nutrients that help support red blood cell production, energy metabolism, thyroid function, immune health, bone health, and more.
This panel includes commonly ordered lab tests for vegetarians and vegans, measuring nutrients associated with anemia, as well as iodine, zinc, and vitamin D. This test may be a good fit if you follow a vegan or vegetarian diet, recently changed your diet, take supplements, or want more information before talking with a healthcare provider.

A vegetarian or vegan diet can be a healthy choice, but some nutrients may be harder to get from plant-based foods alone. This test can help you learn more about key nutrient levels, including iron-related markers, vitamin B12, folate, iodine, zinc, and vitamin D.
Whether you are new to a plant-based diet or have followed one for years, testing can provide useful information about your nutritional needs. Your results can help support a more informed conversation with your healthcare provider about your diet, supplements, and overall health.
Whether you are starting or already following a vegetarian or vegan diet, this test can help establish a baseline for key nutrient levels. Use your results as a starting point to better understand your current nutrition and track changes over time.

Vitamin B12 plays an important role in nerve function. Low B12 has been linked with nerve-related concerns, but numbness, tingling, or pain can have many causes and should be evaluated by a healthcare provider.5 This test measures B12 levels as one part of a broader review, but it cannot diagnose the cause of neuropathy.
This test can be very helpful if you take supplements. Vitamins and minerals can affect your nutrient levels, but it can be hard to know what your levels are without testing.

Your results can help you have a more informed conversation with a healthcare provider before starting, stopping, or changing any supplements.
This panel does not directly measure antioxidant levels. However, it does measure nutrients that support important body functions, including zinc, vitamin D, vitamin B12, folate, iodine, and iron-related markers. Antioxidants are found in many fruits, vegetables, and grains. Some antioxidants, such as vitamins C and E, are also available as dietary supplements.
