symptoms of vitamin deficiency

It’s important to know the symptoms of vitamin and mineral deficiency because it is a common problem in today’s world.

A nutrition report from the CDC suggests 10% of Americans are deficient in at least one nutrient. If you live elsewhere, levels of nutrient deficiency are higher than 40% (see resources below).

Vitamin and mineral deficiencies can lead to a dizzying array of symptoms.

This blog post will discuss the top 14 of these symptoms! 

1 – Tingling fingers or feet

hand tingling

The technical term for “tingling fingers” is paresthesia.

Paresthesia is where you feel a sensation of pins and needles or numbness, usually in your hands and feet.

Other similar symptoms include:

  • skin crawling
  • itching
  • your fingers or toes “fell asleep”

The symptoms are often worse at night when you’re trying to sleep! They can be caused by many conditions such as:

  • Stroke and/or mini-stroke
  • Diabetes mellitus
  • Kidney failure
  • Lyme disease
  • Vitamin deficiency

As this article focuses on vitamin and mineral deficiencies, the deficiencies that may also cause paresthesia:.

  • Calcium deficiency
  • Vitamin B12
  • Magnesium deficiency
  • Vitamin B5
  • Vitamin E

Paresthesia is very common among older people so it’s important for seniors’ caregivers to know the symptoms.

If left untreated, paresthesia could lead to serious health problems like heart attack and stroke.

Treating an underlying vitamin deficiency may help reduce symptoms but please talk with your physician if you have any concerns about your symptoms worsening over time.

2 – Abnormal heart rate

abnormal heart rate

The technical term for an abnormal heart rate is “atrial fibrillation”.

Atrial fibrillation is a heart rhythm disorder where the heart’s two upper chambers (atria) beat irregularly and out of sync with the two lower chambers (ventricles).

This can cause symptoms like:

  • heart palpitations
  • shortness of breath
  • chest pain
  • dizziness
  • fainting
  • weakness

Left untreated, atrial fibrillation can lead to stroke, heart failure and other heart-related complications.

Atrial fibrillation symptoms vary from person to person. You may not experience all of the symptoms listed here so it’s important to be aware of what to look for.

Causes of atrial fibrillation include:

  • congestive heart failure
  • kidney disease
  • high blood pressure (hypertension)
  • diabetes mellitus
  • vitamin or mineral deficiency

What are the vitamin and mineral deficiencies that cause atrial fibrillation?

  • Vitamin D
  • Magnesium
  • Potassium
  • Vitamin B12

3 – Fatigue

Fatigue is a feeling of tiredness that can be mild or extreme.

It’s one of the most common symptoms of vitamin or mineral deficiency and can have many other causes:

  • lack of sleep
  • poor diet
  • stress
  • illness
  • medication side effects
  • excessive exercise
  • vitamin or mineral deficiency

In terms of vitamin or mineral deficiency, it’s difficult to create a short list because any deficiency may lead to a feeling of fatigue.

The most likely vitamin and mineral deficiency culprits leading to fatigue:

  • Vitamin D
  • Vitamin B-12+
  • Iron
  • Magnesium
  • Potassium

4 – Getting sick more easily

If you find yourself getting sick more easily then you may have a vitamin deficiency.

In severe cases of deficiency, you can totally compromise your immune system and die!

Not only do different types of heart failure have strong epidemiological associations with low and high levels of vitamin D, but there are also many ways that vitamin D directly impacts the heart. These include regulating blood pressure, helping maintain healthy blood vessels and preventing the buildup of plaque in the arteries.

Of course, there are many potential causes of getting sick more frequently, including:

  • Less sleep
  • More stress
  • Poor diet
  • Exposure to pollutants
  • Vitamin deficiency

In terms of vitamin deficiency specifically, the most likely culprit by far is a lack of Vitamin C!

5 – Impaired mental and physical development


Impaired development caused by vitamin and mineral deficiencies are common in less developed parts of the world.

In developing countries, there are major public health problems which impact over 2 billion people.

A lack of vitamins and minerals relates directly to many problems such as:

  • retardation of physical and mental growth
  • blindness
  • muscle weakness
  • mental confusion

What are the primary vitamin and mineral deficiencies causing these problems?

  • Vitamin A
  • Zinc
  • Iodine
  • Iron

6 – Weaker bones

The most obvious example of weak bones caused by vitamin and mineral deficiency is rickets.

Rickets is where the bones become soft and weak because they’re not getting enough calcium and vitamin D.

This can lead to problems like:

  • bowed legs
  • poor posture
  • abnormal curvature of the spine (scoliosis)
  • bone pain
  • soft bones

However, a lack of calcium can also cause adults to have weak bones in later life, resulting in:

  • broken hip
  • fractured bones
  • brittle nails

While calcium is the obvious mineral deficiency, there are several vitamins which support calcium absorption such as:

  • Vitamin D deficiency
  • Vitamin K
  • Magnesium

Vitamin D deficiency is important to look at because Vitamin D helps your body absorb calcium.

For this reason many women who are worried about osteoporosis take a vitamin D supplement.

Of course, you can also just eat iron-rich foods, which will lead to better health conditions (instead of just relying on a supplement for health bones)

7 – Hair loss

Hair loss can be caused by many factors but vitamin or mineral deficiency is one of them. 

In fact, a lack of certain vitamins can lead to hair loss all over the body including:

  • the head

Eye twitching is a very common symptom of vitamin deficiency.

In fact, it’s a symptom that often goes undiagnosed as the sufferer assumes that it’s just a random occurrence.

The twitch may be in one eye or both and can last from a few seconds to several hours.

It’s usually not painful but there can be some symptoms that accompany the twitch including:

  • pain in or around your eye
  • a feeling of irritability
  • tiredness

All of these can be symptoms of a vitamin deficiency.

9 – Heel cracks

heel cracks

Heel cracks are symptoms of vitamin or mineral deficiency, along with lack of moisture .

They’re very common symptoms particularly in older people, but can also affect younger sufferers too.

The symptoms include:

  • painful cracking or flaking skin around the heels and balls of your feet
  • dryness to the point of itchiness
  • increased dryness and scaling in between toes

Heel cracks can be symptoms of a vitamin or mineral deficiency because:

  • Vitamin D helps your body absorb calcium, which strengthens bones.
  • Vitamin C is needed for the formation of collagen. Collagen keeps skin strong and elastic; it also supports connective tissue that holds cells together.
  • Iron helps carry oxygen to your cells so that they can function normally and keep the skin healthy by producing collagen for strong, elastic tissue.
  • Vitamin A plays an important role in skin health because it is needed for sebum production which keeps the skin soft and pliable.

There are some symptoms of vitamin deficiencies that aren’t as obvious as others.

For example, symptoms of vitamin deficiency can include stomach pain and cramps which are often attributed to other causes. Same with heel cracks!

You could easily just be chronically dehydrated.

However, having a lack of vitamins in your diet can also cause this type of discomfort so it’s worth checking with your doctor if you think you might have symptoms related to your diet or lifestyle.

For more on this, see the same CDC report (see Resources below).

How do you know if you have a deficiency (and not something else)?
