Beneficial Effects of Spirulina on Brain Health: A Systematic Review

Abstract

This review provides a concise overview of existing scientific research concerning the potential advantages of incorporating spirulina, a blue-green algae, into one's diet to promote brain health. The substantial nutritional composition and associated health benefits of algae have drawn significant interest. Numerous studies have illuminated the neuroprotective characteristics of spirulina, contributing to its positive influence on brain functionality. Primarily, spirulina boasts antioxi-dants, like phycocyanin and beta-carotene, that effectively counter oxidative stress and curb in-flammation within the brain. This is particularly significant as these factors play roles in the ad-vancement of neurodegenerative conditions like Parkinson's and Alzheimer's disease. Additional-ly, spirulina has demonstrated the capacity to enhance cognitive capabilities and enrich memory and learning aptitudes. Animal-based investigations have revealed that introducing spirulina can bolster spatial learning and memory, as well as guard against cognitive decline linked to aging. Research has in-dicated its potential in shielding against neurotoxins, encompassing heavy metals and specific en-vironmental pollutants. Its potential to neutralize heavy metals and counteract free radicals con-tributes to these protective effects, potentially thwarting neuronal harm. In conclusion, the extant scientific literature proposes that spirulina integration can elicit advantageous outcomes for brain health. Its antioxidative, neuroprotective, cognitive-enhancing, and mood-regulating properties present a promising avenue for bolstering brain health and potentially diminishing the susceptibility to neurodegenerative ailments. Nonetheless, further research, notably well-designed human clinical trials, is imperative to ascertain the optimal dos-ing, duration, and enduring consequences of spirulina supplementation concerning brain health.
