Does a vegan diet cause depression?

No. Recent meta-analyses find no consistent link between well-planned plant-based diets and higher depression risk; some cohorts show modest improvements in mood when overall diet quality rises. Symptoms occasionally attributed to “going vegan” usually track under-eating, low B12, low omega-3 or iron deficiency — all fixable with basic planning.

Which nutrients matter most for mood and cognition?

Vitamin B12 (from a supplement), long-chain omega-3s (algae DHA/EPA), iron, iodine, zinc, vitamin D, and enough total calories and protein. Deficiencies in any of these — vegan or not — can flatten mood, memory and energy.

Do I need to eat fish for omega-3s?

No. Algae oil delivers DHA and EPA directly, without the mercury, PCBs or overfishing concerns tied to fish oil. Aim for 250–500 mg combined DHA+EPA per day.

Can a plant-based diet reduce anxiety?

Randomised trials of Mediterranean and plant-forward diets show reductions in anxiety and depressive symptoms, largely mediated by fibre, polyphenols and improved gut microbiome diversity.
