Protein supplements, while not a primary treatment for Cluster Headache, may indirectly support neurological health through amino acid modulation of neurotransmitter synthesis and potential anti-inflammatory effects. Some proteins, particularly those rich in tryptophan and tyrosine, can influence serotonergic and dopaminergic pathways that might help mitigate neurogenic inflammation associated with cluster headache pathogenesis. However, their role remains supportive and is not considered a direct therapeutic intervention for acute or prophylactic cluster headache management.
