Vegan Nutrition Test in California

What this test measures

Plant-based diets can be rich in fiber and low in saturated fat, but they also leave out the main dietary sources of certain nutrients. Vitamin B12 occurs naturally almost only in animal foods, while vitamin D, iron, zinc, calcium, and omega-3 fats can be harder to obtain from plants alone. This panel groups several of those markers so a single blood draw can show where intake may be falling short.

The panel is collected as a standard blood sample and may include serum vitamin B12, folate, vitamin D, ferritin, iron studies, calcium, zinc, and a complete blood count. Some versions add homocysteine or methylmalonic acid, which can rise when B12 is low. Each marker is reported with its own reference range, and values are interpreted together rather than in isolation.

People choose this testing for different reasons. Long-term vegans and vegetarians may use it for routine monitoring, while others order it after symptoms such as fatigue, numbness, or muscle weakness. It can also help when a healthcare provider wants to check whether fortified foods and supplements are keeping levels in range. The test is educational and does not replace an evaluation by a qualified provider.
