Nutrients of concern fall into 3 categories:  
1) Nutrients which are absent (or virtually absent) in plant foods (e.g., DHA/EPA, vitamin B12, preformed vitamin A).  
2) Nutrients which are present in unreliable and/or low quantities (e.g., iodine, selenium).  
3) Nutrients in plants which are low in bioavailability (e.g., zinc, iron)*.  

*Technically, most nutrients from plants are lower in bioavailability compared to animal-based foods. But oftentimes, this doesn't present a cause for concern.  

Here you will find all of the nutrients of concern and learn about how to overcome potential deficiencies.  

At times supplementation may be appropriate. But please run this by your doctor first – especially if you take medication – as they may interact.
