How does anxiety affect us?

First, in a state of stress, the body rapidly depletes its resources to keep the nervous system functioning properly.

Second, stress disrupts digestion and gut function, making it harder to absorb nutrients.

Third, many people who are under stress either lose their appetite or overeat, choosing fast carbs and junk food—foods that contain almost no vitamins or minerals.

As a result, a vicious cycle occurs: stress causes vitamin and mineral deficiencies, and those deficiencies, in turn, worsen anxiety.

What can help?

Magnesium: it’s essential for the nervous system, muscle tone, blood pressure regulation, and energy metabolism. The body cannot produce it on its own—it must come from external sources. That’s why 80% of people worldwide are magnesium-deficient. The minimum daily requirement is 400 mg. Active forms like magnesium citrate, malate, and glycinate are well absorbed when taken with food. Magnesium malate is best in the morning as it energizes and boosts mood. Glycinate is better in the evening as it calms and helps with sleep. However, research shows magnesium only improves mood if there’s a real deficiency, so it’s best to get tested first.

Increased anxiety is one of the common symptoms of magnesium deficiency.

B vitamins: vitamins B5, B6, and B12 play an especially important role in nervous system health. When B12 is lacking, the body may accumulate methylmalonic aldehyde, a toxic compound that damages nerve cells. For prevention, B-complex or individual B vitamins are best taken in the morning after food as they are stimulating.

Vitamin D: in addition to its many functions, it helps synthesize neurotransmitters like serotonin and dopamine—your “feel-good” hormones. Deficiency can lead to low mood and fatigue. Daily vitamin D supplementation is recommended for everyone, especially in areas with limited sunlight. A safe adult dose is 2000–5000 IU per day. For better absorption, take it at breakfast, separately from other fat-soluble vitamins.

Omega-3 fatty acids: these polyunsaturated fats are vital for brain and nervous system health. They have anti-inflammatory effects and may improve mood and reduce anxiety. As with other supplements, the right dose should be determined by your doctor.

Zinc: important for immunity, mood regulation, and cognitive functions. Zinc deficiency can cause anxiety and memory problems. Preventive doses are 10–12 mg for women and 13–15 mg for men per day. Take zinc after meals, choosing well-absorbed forms like picolinate or glycinate.

Iron: iron deficiency leads to anemia, which can cause fatigue, weakness, irritability, poor concentration, and worsen anxiety. A mild deficiency can be addressed through a diet that includes beef, turkey, eggs, and seafood. In more serious cases, a healthcare provider can prescribe the appropriate form and dose.

Vitamins and minerals won’t eliminate stress, but if your body is deficient, correcting those imbalances can greatly improve nervous system function.
