Brain • Mood • Focus

Sustained concentration relies on dopamine synthesis and efficient cortical blood flow. Nutrient deficits or prolonged stress quickly blunt these pathways. Tyrosine and Rhodiola boost catecholamine availability, whereas theanine raises alpha-wave activity for calm alertness. Lion’s mane plus magnesium bisglycinate protect synaptic membranes, delivering sharper working memory without stimulants.
