Panic attacks (PA) and hyperventilation attacks (HVA) are generally considered as ‘mental’ health issues. But a growing body of evidence indicates that what we eat and how we live strongly influence our mental and emotional state.
One such piece of evidence from Japan suggests an interesting link between iron and vitamin B6 levels and PA or HVA.
This study involved pre-menopausal women with PA or HVA (research group, n = 21) and 20 healthy volunteers. None of the study participants had liver disease, kidney disease, endocrine or inflammatory issues and none were regularly taking food supplements.
Serum levels of vitamins B2, B6, B12, and iron were measured either during visits to the emergency department (research group) or after overnight fasting (control group).
What the research showed:
- Iron and vitamin B6 levels were significantly lower in the study group compared to the control group.
- The study participants had similar hemoglobin, thus ruling out iron-deficiency anemia as a cause of PA and HVA.
- The two groups showed no significant difference in vitamins B2 and B12 levels. This suggests that reduced intake due to illness did not cause PA and HVA.
The authors suggest that, since iron and vitamin B6 are involved in the formation of serotonin in the brain, deficiency of these nutrients could suppress serotonin production and cause PA and HVA.
In a brand-new study, researchers investigated the efficacy of the following nutrients as adjunctive treatments for depression:
- Vitamin D – Low levels of this vitamin have been associated with depression. One proposed mechanism is that vitamin D modulates the HPA axis and regulates neurotransmitter synthesis.
- Vitamin B9 and B12 – Deficiencies of these vitamins can reduce homocysteine recycling which can impair neurotransmitter synthesis, membrane phospholipids, and cause anemia.
- Vitamin C – Since depression can be triggered by oxidative-stress, antioxidant vitamin C could help alleviate symptoms.
- Zinc – This mineral may help downregulate neurodegenerative inflammatory pathways of depression.
- Selenium – Low selenium intake has been linked to increased risks of de novo major depressive disorders.
- Omega-3 fatty acids – Since these fatty acids are key components of gene expression regulation and cell lipid metabolism, deficiencies can trigger depression.
- N-acetylcysteine – In one study, 1,000mg of N-acetylcysteine helped reduce manic and depressive symptoms significantly by neutralizing reactive oxygen species thereby preventing cell damage.
- Nicotinamide riboside acts as a co-substrate for enzymes that are involved in DNA repair.
Keep in mind: You can’t out-supplement a nutrient-poor diet or an unhealthy lifestyle. One of the (many) reasons is that unlike real foods, supplements do not come with cofactors the body needs to absorb specific nutrients. Don’t know where to start? My free guide can help you.
The microbiome exerts a major influence on neurological health since our brains and gut are linked. Research shows that an inflamed gut promotes the release of inflammatory molecules (cytokines) in the bloodstream. These cytokines are able to cross the blood-brain barrier and induce inflammation in the brain, creating neurological symptoms like depression, anxiety, and stress.
Improving the gut health with specific strains of probiotics can positively influence mental health. For example, Lactobacillus helveticus R0052, Bifidobacterium longum R0175, and Lactobacillus rhamnosus R0011 can ameliorate depression, anxiety, and stress respectively.
A new study shows that supplementing with probiotics, prebiotics, and phytobiotics (i.e. phytonutrients such as polyphenols) for 30 days work together to increase beneficial bacteria. This can, in turn, improve:
- Global mood
Journal reference: Talbott, S., Stephens, B., Talbott, J., & Oddou, M. (2018). Effect of Coordinated Probiotic/Prebiotic/Phytobiotic Supplementation on Microbiome Balance and Psychological Mood State in Healthy Stressed Adults. The FASEB Journal, 32(1_supplement), 533-85.
Around 90% of serotonin receptors are located in the gut. As such, it makes sense that digestive health, and the gut’s microflora, can have a tremendous impact on mood.
In a review of studies, scientists explain that numerous lab studies indicate that probiotics can improve anxiety-like and depressive-like behaviors. For instance:
- When taken together for 14 days, Lactobacillus helveticus and Bifidobacteria longum helped reduce anxiety.
- Lactobacillus rhamnosus decreased both anxiety-like and depressive-like behaviors when administered for 28 days.
- A 21-day intake of Lactobacillus helveticus helped to reduce anxiety triggered by a high-fat diet. It is worth noting that the high-fat (non-hydrogenated lard and sunflower oil) diet in this particular study was, in fact, a Western-style diet rich in refined sugar.
It appears that probiotics can protect the gut’s lining from the adverse effects of stress by decreasing the activity of the autonomic nervous system and the HPA axis (which is involved in stress response). This, in turn, leads to reduced plasma levels of adrenaline, noradrenaline, and corticosterone in stressed mice.
Interestingly, probiotics may not alleviate anxiety induced by a high-fat (Western-style) diet in the absence of anti-inflammatory cytokines produced by immune cells. What this means is that fixing food before trying gut-modifying therapies may yield better results.

Essential oils have been used for hundreds of years for their relaxation properties. And in 2017, research showed that orange essence could help alleviate anxiety in children with type 1 diabetes.
60 Iranian children aged 6 to 12 were enrolled in the study and allocated to the intervention (n=30) or the control group.
In the experimental group, two drops of orange essence were used on a strip of gauze inside an open box kept at a 5-cm distance from the child’s nose. The children were asked to breathe in deeply for about 2 minutes. This procedure was repeated thrice weekly on Saturday, Monday, and Wednesday before bedtime for two weeks.
Diabetes care remained unchanged in the control group.
All the children completed an anxiety questionnaire before and after the intervention.
Results indicate that the essential oil helped to significantly reduce (i) physiological anxiety, (ii) social anxiety, and (iii) tendency to worry in the intervention group.
The researchers report that, besides orange essence, lavender and rose essential oils are also commonly used for their anti-stress and anxiety relief properties.

Inborn errors of metabolism (IEMs) are rare disorders involving a faulty gene that makes it difficult for the body to convert food into energy.
The treatment for IEMs typically involves dietary manipulations, which along with genetics, can influence the health of the microbiome. For instance, excessive food intake or food restriction, can lead to gut dysbiosis, an imbalance in the type and/or quantity of bacteria present in the gut.
This gut dysbiosis can further alter the metabolic state of a person with an IEM by worsening the functions of the liver and the brain, the two major organs already affected by IEMs.
As such, an unhealthy microbiome can cause:
- Neurocognitive issues (mood and behavior disorders, coordination problems, and cognitive disorders)
- Issues with the gut-brain interactions, increasing risks of cardiovascular risk, multiple sclerosis, anxiety, depression, autism, and Alzheimer’s disease.
- Liver problems (cirrhosis and non-alcoholic fatty liver disease)
