Common Nutrient Deficiencies: Signs & Symptoms
Updated: May 26

Have you ever had vague or strange symptoms that your doctor just couldn't diagnose? Have you ever wondered if your ambiguous symptoms and general malaise could ever be linked to a nutritional deficiency? Unfortunately, nutrient deficiencies and insufficiencies aren't as uncommon as would be expected in developed countries.
Surprised?
You shouldn't be. Studies show that if you're eating a western diet (Standard American Diet or SAD), then you're not getting enough nutrients like magnesium or choline. Sad indeed, right?
The sad (sorry for the puns) reality is that our food supply has been pretty much hijacked by companies that don't necessarily have your best interest in mind. The bottom line, the almighty dollar, is these companies biggest concern, not nutrition.
So how would you know if some of the symptoms you are having are due to nutrient deficiencies? It's not like your doctor will ask for a detailed diet diary and order labs to access nutrient analysis (unless you're seeing a naturopathic doctor).
If you've been having unexplained symptoms that are hard to diagnose, here are some of the most common nutrient deficiencies and insufficiencies with signs and symptoms.
*Note: There's a difference between a deficiency and an insufficiency. A deficiency is considered a clinical disease that needs immediate treatment An insufficiency may not even be recognized by your clinician although you have many signs and symptoms of lacking a specific nutrient or nutrients.
Common Nutrient Deficiencies

Magnesium
Magnesium is a common nutrient deficiency worldwide with studies estimating that those eating western diets have a dietary magnesium intake up to less than 50% of the recommended daily intake.
Magnesium is a necessary nutrient for over 300 enzymatic reactions in the body. It's needed for protein synthesis, conduction of muscle and nerve cells, and blood sugar control. Just to name a few.
Magnesium deficiency and insufficiency signs
Some of the signs and symptoms of magnesium insufficiency include:
High blood pressure
Migraine headaches
Depression, irritability, and mood disturbances
Poor quality sleep or lack of sleep
Cramps, muscle aches, and pains
Constipation
Insulin resistance
Frank magnesium deficiency can be fatal causing heart arrhythmia, seizures, and low potassium.

Choline
Choline is a nutrient that can act as a methyl group donor in many different metabolic processes. It also acts as building block for phosphatidylcholine and sphingomyelin, molecules that help build cell membranes.
Choline is also necessary for proper brain and liver function. In fact, choline it's estimated that many adults and children have an inadequate daily intake of choline especially among college students, children with a low socioeconomic status, and adults eating a SAD diet.
Although the National Institutes of Health would say that choline deficiency is rare, there is evidence that the increased prevalence of non-alcoholic fatty liver disease, that many individuals aren't consuming enough choline.
NAFLD (non-alcoholic fatty liver disease) is caused, in part, by a lack of choline.
Choline Deficiency and Insufficiency signs
Non-alcoholic fatty liver disease
Increased homocysteine levels which is linked to poor cardiovascular health
Muscle weakness
Cognitive decline
Fatigue
Increased sleepiness and daytime sleepiness

Vitamin D
Vitamin D deficiency and insufficiency is thought to affect 1 billion adults and children worldwide. Vitamin D is an important vitamin that acts more like a steroid hormone in the body.
Sufficient vitamin D levels are necessary for everything from reducing inflammation to improving immunity.
Vitamin D is synthesized by the body from ultraviolet light hitting skin. It's then further processed by the kidneys and the liver to be available for use in the body.
Vitamin D Deficiency and Insufficiency Signs
Body aches and pains
Getting sick more often
Depression, sadness, and low moods
Hair loss
High blood pressure
Addressing Nutrient Insufficiencies
So if you find that you have some of these signs and symptoms, how do you address low nutrient status?
Eating a magnesium rich diet can help improve your total magnesium status. Foods high in magnesium include: pumpkin seeds, spinach, almonds, chia seeds, and cashews.
Choline rich foods include: eggs, especially the yolk, chicken breast, soybeans, and beef liver.
Foods rich in vitamin D include: trout, salmon, cod liver oil, sardines, eggs, and beef liver.
Sometimes diet isn't enough to increase your nutrient status. This is because our foods are grown in nutrient depleted soil, picked before they are ripe, shipped over long distances, and kept in stores for long periods of time to prevent spoilage.
If you find that you can't get enough of the nutrients you need from your diet, you may benefit from taking supplements. While nutrient insufficiencies can be a cause of you hard to explain symptoms, there may be other issues that need to be addressed.
Your naturopathic doctor can help create a personalized plan of action to help you get to feeling your best.
