The 5 Nutrients Most Americans are Lacking

If you’re reading this, then in all likelihood, you have enough to eat. But even those of us in such a position are at risk for nutrient deficiencies. Nutrient deficiencies are categorized by insufficient intake or absorption of a particular vitamin or mineral, and can occur even when one has plenty of food to eat. In fact, America is often considered one of the most overfed and undernourished nations in the world, with 10% of the population having a nutrient deficiency. It’s easy to see why when so many American foods are calorie-dense but nutrient-poor. Here are the five most common nutrient deficiencies in the United States today. 


Iron deficiency is incredibly common, especially among women and girls. That’s because it can occur not only through inadequate consumption, but also due to poor absorption and loss of blood through menstruation. Common symptoms are fatigue, headaches, and dizziness. We recommend Integrative Therapeutics Iron Complex to ensure you meet your daily requirements.  

Vitamin D

This one is especially important to note as we head into winter. A healthy body can synthesize all the vitamin D it needs from sunlight, but 35% of us aren’t getting the recommended amount in the winter months.  Vitamin D is key for regulating calcium absorption as well as autoimmune function and bone and cardiovascular health. For that reason, we recommend Nordic Naturals Vitamin D3 for anyone who can’t soak up enough sun to meet their requirements. 

Folic Acid

Folic acid is an incredibly important nutrient for both pregnant women and infants. While the nutrient is plentiful in leafy greens, brussel sprouts, broccoli, beans, and fortified cereals, pregnant women are often advised to add a folic acid supplement to their routine. 


Magnesium aids in a wide range of processes in our bodies, so being deficient can look very different from person to person. Its symptoms range from muscle cramps to abnormal heart rhythms.


Like iron deficiency, B12 deficiency often affects vegetarians and vegans and causes anemia. B12 is very important for the formation of red blood cells and nerve cell health, but since it is primarily found in animal products like dairy and meat, those who consider themselves herbivores are advised to supplement. DaVinci labs makes it easy with these chewable capsules.
