If you struggle with anxiety, you are not alone. Approximately 40 million adults struggle with anxiety in the U.S. every year.

Anxiety is a serious condition. To properly cope with anxiety, you should consult a doctor or therapist. But there may be other things you can also do to help along the way.

Do you know one of the worst side effects of vitamin deficiencies? Anxiety. The following is a list of seven vitamin deficiencies that may be causing you additional or unnecessary anxiety.

1. Iron Deficiency

If you've been wondering what vitamin deficiencies cause anxiety, iron is a good place to start.

One of iron's main jobs in your body is to help build and maintain serotonin and dopamine. These are mood-regulating chemicals, so if they are unbalanced, you may experience feelings of anxiety or stress.

Other common indicators of an iron deficiency include dizziness, feeling lightheaded, or chronic fatigue. 

2. Magnesium Deficiency

Magnesium is known as a mood-stabilizing mineral that can help you process stress. Not having enough of it can cause you to feel stressed or overwhelmed.

If you are magnesium-deficient, you may experience sudden mood changes. Physical symptoms may include a loss of appetite or feeling fatigued.

3. Vitamin B1 Deficiency

If you are deficient in Vitamin B1, you may feel more stressed or anxious than usual. Vitamin B1 is known for its calming influence, which can help with stress levels.

In general, B vitamins help with energy production. Therefore, it's important to make sure you're getting all of your B vitamins. But when it comes to stress, a lack of Vitamin B1 is one of the main vitamin deficiencies that cause anxiety.

4. Zinc Deficiency

Zinc is a mineral that will help with brain function. Paired with Vitamin B6, it helps your body produce serotonin and dopamine.

Getting enough zinc is crucial for your brain. Other side effects of a deficiency may include a loss of temper, learning difficulties, or depression.

5. B6 Deficiency

As we said in #4, you need to get enough B6 in order to appropriately produce serotonin and dopamine. B6 also aids your neurotransmitters to ensure a balanced mood and an appropriate sleep schedule.

If you are deficient in Vitamin B6, you may experience anxiety, depression, irritability, and difficulty concentrating.

6. Vitamin D Deficiency

Vitamin D is a key player in serotonin activity. As we've alluded to above, serotonin influences mood and sleep, as well as appetite and digestion. If you are deficient in Vitamin D, you may experience fatigue or increased anxiety levels.

7. Vitamin B12 Deficiency

As we've said before, it is important for your mental and emotional health to get enough of all of your B Vitamins. Vitamin B12 is no exception.

Vitamin B12 helps regulate mood-boosters like serotonin and dopamine. It also helps manage stress hormones such as norepinephrine. 

If you don't meet recommended B12 levels, you could experience chronic fatigue or even brain fog.
