The Australia cognitive health supplements market is experiencing exceptional growth, driven by the convergence of a rapidly aging population, rising dementia prevalence, increasing consumer awareness of brain health and mental wellness, the emergence of clinically validated nootropic formulations, and growing demand for proactive cognitive support across all age demographics. The Australia cognitive health supplements market size reached USD 372.9 Million in 2025, reflecting the structural shift in Australian consumer behaviour toward preventive brain health supplementation. An estimated 433,000 Australians are living with dementia in 2025, with dementia ranking as the second leading cause of death in Australia and the leading cause of death among Australian women in 2023. The rate of dementia rises sharply with age — from less than 1 per 1,000 Australians aged 30-59 to 84 per 1,000 aged 65 and over, and 292 per 1,000 aged 85 and over — creating a powerful demographic driver as Australia's population continues to age. Products tailored toward supporting mental wellness, memory, cognitive performance, and stress resilience are seeing significantly higher demand, with Australian consumers increasingly valuing supplements backed by scientific evidence and clinical research.

Looking forward, the Australia cognitive health supplements market is expected to reach USD 1,375.3 Million by 2034, exhibiting a growth rate (CAGR) of 15.14% during 2026-2034. This exceptional growth trajectory is being underpinned by the projected near-doubling of dementia prevalence to an estimated 812,500 Australians by 2054, the expansion of nootropic product ranges by major Australian supplement brands, the growing body of clinical evidence supporting omega-3 fatty acids, herbal compounds, and probiotic-based cognitive formulations, and the increasing integration of brain health into mainstream wellness culture. Swisse launched its new nootropics range in late 2024, focusing on cognition and memory enhancement, while in August 2025 Western Sydney University announced that NICM and BioCeuticals began a three-year research trial to assess the impact of herbal and nutritional supplements on cognitive function in older adults with Mild Cognitive Impairment (MCI). The market is being further shaped by the growing influence of personalised nutrition platforms, the expansion of online retail channels that improve consumer access to specialised cognitive supplements, and the increasing crossover between mental health awareness campaigns and cognitive supplementation as Australians seek holistic approaches to brain health that encompass memory support, stress management, mood enhancement, and long-term neuroprotection.
