Folate

What is folate? Folate is vitamin B9. Folate-containing foods encompass vegetables, including broccoli, asparagus, spinach, and Brussels sprouts.

Deficiency of folate

Cooking these vegetables can trigger folate loss, potentially diminishing our consumption of this vital nutrient.

Folate versus folic acid

Folate represents vitamin B9's natural form, while folic acid constitutes the synthetic version, manufactured for health supplementation.

Supplementation with folate acid

Recent investigations spanning over five years have concentrated on folate supplementation's influence on older adults, disclosing its beneficial cognitive health effects.

In their most recent two-year investigation, scientists evaluated folic acid supplementation's cognitive advantages.

Half the participants received folic acid supplements (400 mcg/day), while the remaining participants received standard care guidance on nutrition and physical activities for supporting later-life memory.

The investigation determined that after 24 months, the folic acid supplement group demonstrated:

Improved cognitive performance

Folic acid group participants demonstrated substantial cognitive test score improvements, encompassing full-scale IQ, verbal IQ, and memory test increases.
Their performance on six verbal IQ tests and comprehensive scores across all 11 tests revealed a notable cognitive ability enhancement.

Beneficial DNA methylation marker changes

Folic acid supplementation additionally triggered gene modifications related to DNA methylation, a mechanism vital for homocysteine metabolism.
The supplementation elevated folate and S-adenosylmethionine (SAMe) levels, a compound essential for key neurotransmitter production and depression resistance.
Simultaneously, homocysteine and S-adenosyl homocysteine (SAH) levels, both associated with negative cognitive outcomes, including stroke and dementia, decreased.
The SAMe/SAH ratio, a healthy methylation indicator, also improved.

These discoveries emphasize folate's significance in sustaining cognitive performance. Supplementation could represent a valuable approach to promoting brain wellness in older adults.
