However, scientists have only sometimes supported supplement manufacturers’ claims regarding dietary brain supplements. Therefore, it is recommendable to check with a doctor before taking a particular product.
What are the best brain supplements?
Omega-3 fatty acids, antioxidant supplements, and B vitamins may all benefit brain supplements, according to research.
The omega-3 fatty acids
To determine their potential benefits for brain health, researchers often study omega-3 fatty acids, such as alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). Omega-3 fatty acids obtained from fish appear to reduce the risk of impaired cognitive function in middle-aged people, according to an older study. However, it is worth noting that in a 2010 study conducted by Trusted Source, DHA supplements did not slow the cognitive decline of people with mild-to-moderate Alzheimer’s disease compared with placebos. Furthermore, a 2015 literature review concluded that, despite lower DHA and EPA levels in people with neurodegenerative conditions, DHA might provide better health benefits in older adults.
Supplements with antioxidants
There is some evidence that dietary antioxidants may help prevent cognitive decline caused by aging in older mice studied in 2012. According to the study, oxidative stress contributes to age-related cognitive decline by increasing reactive oxygen species in the brain. Almost completely reversing the accumulation of ROS in the brain was noted by the study’s authors. A recent FDA ruling made it clear that N-acetyl cysteine (NAC), an ingredient in this study, is not eligible to be marketed as a dietary supplement.
Trusted Source found in a 2016 review that studies on B vitamins and brain health have focused mainly on B6, B9, and B12. According to this study, people with vitamin B deficiencies are more likely to have impaired brain function. Vitamin B deficiency can have adverse health consequences. This author claims that a single B vitamin may not be as effective as supplementing a diet with an entire group of eight B vitamins.
