Two Nutrients That Reduce Brain Fog & Increase IQ

In recent years the discovery that omega-3 and B vitamins are co-dependent, that is one cannot lead to another, led to a study giving people with mild cognitive impairment either the B vitamin folic acid (800mcg) or omega-3 DHA (800mg) or both for one year, compared to those given placebos to test their effects on measures of intelligence.

The individual nutrients worked, but the biggest effect was seen in those given both omega-3 DHA and folic acid. The combination produced a significant improvement in all three measures of IQ (full, verbal and performance IQ), more so than the individual nutrients, showing a clear benefit for those experiencing cognitive decline.

The researchers, from Tianjin Medical University and Hebei Medical University in China, also investigated the effects of the nutrients on mitochondria, the energy factories in cells, and found that those on the nutrients had less oxidative damage to mitochondrial DNA. “The cognitive benefits might act via DNA oxidative damage and mitochondrial function”, they report.

Reduced mitochondrial energy and increased oxidative stress on the mitochondria, may result in brain fog and and cognitive fatigue.

They conclude that “Interventions of folic acid (800mcg) combined with DHA (800 mg) daily orally for 12 months can improve cognitive function in older adults with Mild Cognitive Impairment, and the combined intervention is superior to either intervention alone.”
