top 3 nutrient deficiencies i see in practice

As a Naturopathic Doctor, one of the first things I often investigate with patients is their nutrient levels. Even with a well-rounded diet, certain deficiencies are incredibly common due to our lifestyle, food quality, environmental factors or other health conditions. Three nutrients I see low levels of most often are iron, Vitamin B12, and Vitamin D. Here, we’ll explore why each of these nutrients is essential to wellbeing, what symptoms of deficiency may look like, and some reasons why these nutrients may fall through the cracks for years before being addressed.

IRON

Iron is essential for energy production, oxygen transport, and immune function. It plays a role in carrying oxygen to our tissues, which is why we feel fatigued and drained when iron levels are low. Other signs of deficiency can be brain fog, frequent infections, pale skin, brittle nails, and dizziness.

How Deficiencies Happen

Iron deficiency can be common in menstruating women (ie. heavy periods means losing iron), those with animal-restricted diets (ie. vegetarians and vegans), or anyone with digestive conditions that may impair nutrient absorption (ie. celiac, IBD). Additionally, intense physical activity can increase iron demand on the body over time, making athletes more susceptible to deficiency!

VITAMIN B12

Vitamin B12 is critical for nerve health, red blood cell production (both iron and B12 deficiencies are causes for anemia!), and DNA synthesis. Symptoms of deficiency can range from fatigue and numbness/tingling in the hands and feet to mood changes, memory issues, and muscle weakness.

How Deficiencies Happen

A lack of B12 often arises in individuals who avoid animal products, as B12 is mostly found in animal-derived foods. Low stomach acid also hinders B12 absorption, which is common in older individuals or anyone who has been on “antacid” medications long-term. In some cases, our genetics lead to a condition called Pernicious Anemia, making it harder for some individuals to maintain adequate levels.

VITAMIN D

Vitamin D is not just a vitamin but a hormone that supports immune function, mood regulation, and bone health by aiding calcium absorption. Deficiency symptoms can be subtle, like fatigue or a low mood (especially in the winter), but may also include bone or muscle aches and frequent colds or infections.

How Deficiencies Happen

If you’re living in Canada, you know that sun exposure is limited for part of the year, which is one of the main ways we produce Vitamin D naturally. Spending more time indoors and wearing sunscreen further reduces our skin’s exposure to sunlight.

Testing & Treatment Options

The best way to confirm these nutrient levels is through bloodwork, which gives us a clear picture of any deficiencies and allows for a targeted treatment approach through supplements, vitamin injections, and/or increasing foods rich in these nutrients.

BUT DOES “SUFFICIENT” MEAN “OPTIMAL?”

NO!

The “normal ranges” on bloodwork are designed to flag frank deficiencies, but the reality is that people tend to feel their best when these nutrients are at “optimal” levels.

Many patients come to me feeling tired, sluggish, or “off” only to hear that their bloodwork looks “fine.” If this sounds familiar, an ND can help you explore whether your nutrient levels are where they need to be for YOU to feel your best.

THE PERFECT PLACE TO START

If bloodwork is accessible to you, assessing for these nutrient deficiencies can be the perfect place to start when you’re not feeling good, but we don’t know why. Often people are shocked to hear that their “normal” bloodwork may be contributing to their symptoms, and that simple daily changes can make a massive impact!

Getting to the root of your health can transformative for your energy, mood, metabolism and overall wellness.
