Top 5 Nutrient Deficiencies and Why they are so Important in Women’s Health

It’s proven: 31 percent of people in the United States are at risk for a deficiency in at least one vitamin or mineral essential for good health. It may be hard to imagine that we don’t get enough nutrition when we see abundant food available 24/7, but it’s true. A recent study showed the top five nutrients many of us need more of. 

Should you be concerned about being low in one or two vitamins or minerals? In a word, yes. That’s because vitamins and minerals are essential for optimal health. Being low may not cause immediate symptoms, but it puts you at risk for many serious diseases affecting your brain, heart, blood, immune system, metabolism, bones, mental health, etc. Nutrients are key pieces your body needs to maintain your systems in good working order. Missing just one or two pieces can throw off the delicate balance you need to be healthy and feel great. That’s because most nutrients don’t have just one vital role to play within the body; they play many, many vital roles.

How would you even know if you’re at risk for a nutrient deficiency? It’s not always obvious. Sometimes symptoms aren’t felt for a long time, and sometimes they’re vague and non-specific. For example, fatigue, irritability, aches and pains, decreased immune function, and heart palpitations can be signs of many things, including a nutrient deficiency. This article goes over the five most commonly deficient nutrients, some more obvious symptoms, and foods that are high in each so you can get enough.

1 - Vitamin B6 Deficiency

The number one most common nutrient deficiency in the US was Vitamin B6. This vitamin is important for your blood, brain, and metabolism. Vitamin B6 helps the formation of hemoglobin in the blood (the part that carries oxygen around). It also helps to maintain normal levels of homocysteine (high levels of homocysteine are linked with heart disease). In addition, this vitamin plays an important role in producing neurotransmitters (chemical messengers allowing nerve cells to communicate with each other). Not to mention the fact that it’s also involved with over 100 enzyme reactions in the body, mostly for metabolism. As women move into their 40’s, their metabolism begins to slow, and their bodies change. Vitamin B6 becomes even more essential and is likely depleted. 

Some of the main symptoms of a serious deficiency in Vitamin B6 are depression, confusion, convulsions, and a type of anemia called “microcytic” anemia. Symptoms of a less serious deficiency are no less serious. They include increased risks for heart disease and Alzheimer’s. These wide-ranging health effects are why Vitamin B6 is so essential for health. 

Vitamin B6 is found in all food groups. People who eat high-fiber cereals tend to have higher levels of the vitamin because cereals are often fortified with it. Vitamin B6 is also found in high quantities in potatoes, non-citrus fruits (e.g., bananas), and various animal-based foods such as poultry, fish, and organ meats. 

2 - Vitamin B12

Like Vitamin B6, Vitamin B12 is also very important for your blood and brain. It is needed for the creation of healthy red blood cells and the formation of the outer coating of nerve cells (myelin), which is very important for their optimal functioning. 

Vitamin B12 can be a bit difficult to absorb from your food. To improve absorption, it’s important to have adequate acid and digestive enzymes in the stomach. This is because the vitamin is very strongly bound to the proteins in food, and stomach acid and enzymes help to break those bonds and free the vitamin so your body can take it in. 

Vitamin B12 deficiency can be caused by a type of anemia called “pernicious” anemia. Pernicious anemia is an autoimmune disease that affects the stomach and reduces its ability to absorb Vitamin B12. A deficiency in Vitamin B12 can then lead to a different type of anemia called “megaloblastic” anemia. Low levels of Vitamin B12 can also cause neurological damage (due to impaired myelination of nerve cells). 

Vitamin B12 isn’t naturally present in most plant-based foods, except it is found in some nutritional yeast products. It is naturally found in dairy, eggs, fish, poultry, and meat, particularly in clams, beef liver, trout, and salmon. Many breakfast cereals are fortified with Vitamin B12. 

If you are consuming Vitamin B12 supplements or eating foods fortified with Vitamin B12, your levels of stomach acid and digestive enzymes aren’t as critical as they are for the absorption of the vitamin directly from foods. This is because when adding Vitamin B12 to foods and supplements, it’s not tightly bound to their proteins, making it much more easily absorbed. 

A B-Complex that is high quality is a great way to begin supplementing these vital vitamins. I use this B complex created by Dr. Caroline Dean.

3 - Vitamin C Deficiencies

Vitamin C is important for wound healing (via a protein called collagen), the production of neurotransmitters, metabolism, and the proper functioning of the immune system. Vitamin C also acts as an antioxidant to reduce the damage caused by free radicals that can worsen several diseases, such as certain cancers and heart disease. Vitamin C also helps your body absorb the essential mineral iron, which is one of the top five nutrient deficiencies also included in this article. 

Collagen is a vital component of connective tissue, which describes some of the symptoms of its deficiency disease, scurvy. Symptoms of scurvy include weak connective tissue, such as bleeding, wounds that won’t heal, and even the loss of teeth. 

You can get Vitamin C from many fruits and vegetables. Ones particularly high in Vitamin C include bell peppers, oranges, and orange juice. Other good sources of vitamins include kiwifruit, broccoli, strawberries, Brussels sprouts, tomato juice, cantaloupe, cabbage, and cauliflower. Vitamin C is not naturally present in grains, but some breakfast cereals are fortified with it. 

When choosing foods for Vitamin C, choose the freshest options because levels of the vitamin naturally reduce over time the longer the food is stored. Try, as much as possible, to eat Vitamin C-rich foods raw. If you do cook them, then choose steaming and microwaving instead of prolonged boiling because the vitamin is destroyed by heat and is water-soluble. For supplementation, I like this Vitamin C powder that I can throw in my water. You can check it out here.

4 - Vitamin D Deficiency

Vitamin D, or the “sunshine vitamin,” is very important for your bones. It promotes the absorption of the mineral calcium. When your body has enough calcium, it can maintain normal bone mineralization and prevent problems in the muscles that lead to cramps and spasms. Getting enough Vitamin D and calcium can also help protect against osteoporosis. In addition to all of these bone and muscle impacts, Vitamin D helps to reduce inflammation and modulate both immune function and sugar metabolism. 

Without enough Vitamin D, bones can become thin, brittle, or misshapen. Vitamin D prevents these issues known as rickets (in children) and osteomalacia (in adults). 

Your skin makes Vitamin D when it’s exposed to the ultraviolet rays of the sun, and very few foods naturally contain it. The few Vitamin D-rich foods include fatty fish and fish liver oils (e.g., salmon, trout, cod liver oil). Other foods that naturally contain small amounts of Vitamin D include egg yolks, beef liver, and cheddar cheese. Some mushrooms can contain Vitamin D—particularly those exposed to UV light. 

Most of the dietary Vitamin D that people in the US get is from fortified foods and beverages. These include some dairy products (mainly milk), certain plant milks (e.g., soy, almond, or oat milks), various breakfast cereals, and a few types of orange juice. Be sure to look at the nutrition labels to see if and how much Vitamin D is in each serving of the food or beverage. 

This vitamin D supplement has vitamin K2 included, which increases the absorption because it doesn’t matter how much of a supplement you are taking; if it isn’t absorbed, it won’t matter. Vitamin K2 will also help direct calcium to the bones and teeth. 

5 - Iron Deficiency

Iron is essential for healthy blood to transport vital oxygen throughout your body every second of every day. This happens via a compound in your red blood cells called “hemoglobin.” Iron also supports your muscles (like Vitamin D) and connective tissue (like Vitamin C). Having adequate iron is necessary for physical growth, neurological development, hormone production, and the function of your cells. 

A deficiency in iron is commonly known as “anemia.” Menstruating women tend to be lower in iron simply because of their regular loss of blood. 

Most iron in the body is in the blood, but some are stored in the liver, spleen, bone marrow, and muscles. This is why iron deficiency progresses slowly from depleting your stores (mild iron deficiency) to reducing the number of red blood cells (marginal iron deficiency) before you get to full-out iron deficiency anemia. 

Iron is naturally found in many foods in one of two forms: heme and nonheme. Animal-based foods contain the more absorbable heme form. Plant-based foods naturally contain nonheme iron. This is where Vitamin C comes in. Vitamin C helps your body absorb the nonheme iron from plants, so if plants are a main source of iron in your diet, it’s important to combine iron-rich plants with Vitamin C-rich plants in the same meal.

Some of the best sources of iron include fortified cereals, oysters, white beans, dark chocolate, beef liver, lentils, spinach, and tofu. 

Up to one-third of people in the US are at risk for at least one nutrient deficiency, but women entering pre, peri, and post-menopause are at even higher risk. Most commonly, that deficient nutrient is Vitamin B6, but there are also many people deficient in vitamins B12, C, and D, as well as the mineral iron. Vitamins and minerals are essential nutrients because everybody needs them on a regular basis for good health. Lacking any one nutrient can have far-reaching consequences. 

Eating a nutrient-rich diet with various foods can help everyone achieve their health and nutrition goals.
