Several studies are out further confirming the link between proper supplementation and brain health.
One study focused on vitamin D deficiency in ethnic minorities and found the following:
“Low VitD status was associated with accelerated decline in cognitive function domains in ethnically diverse older adults, including African American and Hispanic individuals who exhibited a high prevalence of VitD insufficiency or deficiency.”
The other two studies focused on supplementation with Vitamin B (Folic Acid, B6, and B12) and Omega-3’s. Both studies found a marked improvement in brain function, especially when supplementation began earlier.
“Eating fish rich in long-chain polyunsaturated fatty acids, such as the omega-3 fatty acids, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), protects against the onset of dementia.”
“…[the] trial showed that a B vitamin supplement (folic acid, vitamins B6 and B12) in older adults with mild cognitive impairment (MCI) slowed the rate of global  and regional brain atrophy  and maintained verbal episodic memory, semantic memory, and global cognitive performance…”
While none of the studies showed any aid to those with full-onset dementia or Alzheimer, it is clear that B and Omega-3 supplementation has a big impact on the general health of the brain, particularly in those with mild cognitive impairment.
If you’re 50 years old or older, this should be a no-brainer (pun intended). Begin supplementing with Omega-3’s and B’s today!
