May Promote Brain Health And Reduce Alzheimers Risk
Vitamin B6 may play a role in improving brain function and preventing Alzheimers disease, but the research is conflicting.
On the one hand, B6 can decrease high homocysteine blood levels that may increase the risk of Alzheimers .
One study in 156 adults with high homocysteine levels and mild cognitive impairment found that taking high doses of B6, B12 and folate decreased homocysteine and reduced wasting in some regions of the brain that are vulnerable to Alzheimers .
However, its unclear if a decrease in homocysteine translates to improvements in brain function or a slower rate of cognitive impairment.
A randomized controlled trial in over 400 adults with mild to moderate Alzheimers found that high doses of B6, B12 and folate decreased homocysteine levels but did not slow decline in brain function compared to a placebo .
In addition, a review of 19 studies concluded that supplementing with B6, B12 and folate alone or in combination did not improve brain function or reduce the risk of Alzheimers .
More research that looks at the effect of vitamin B6 alone on homocysteine levels and brain function is needed to better understand the role of this vitamin in improving brain health.
Summary Vitamin B6 may prevent a decline in brain function by decreasing homocysteine levels that have been associated with Alzheimers disease and memory impairments. However, studies have not proven the effectiveness of B6 in improving brain health.
Excessive Folic Acid Intake
Although folic acid is generally considered non-toxic, excessive intakes above 1,000 mcg per day over a period of time can lead to malaise, irritability and intestinal dysfunction. The main risk with excessive folate intake is that it can mask a vitamin B12 deficiency, so its best to consume these two vitamins within the recommended amounts.
How Long Do You Need To Take Vitamin B6 To Start Experiencing Its Benefits If Youre Deficient
As a water-soluble nutrient, vitamin B6 is absorbed quickly, and it doesnt take long before you will start noticing the beneficial effects of this vitamin.

- Dopamine: responsible for reward-seeking, motivation, and movement
- Serotonin: stabilizes mood, causes feelings of well-being and happiness.
- Melatonin: plays a role in regulating our circadian rhythm and ability to fall asleep
- Noradrenaline: produces the ‘fight or flight’ response in our body when we perceive danger

Tiredness And Low Energy
A vitamin B6 deficiency can leave you feeling unusually tired and sluggish.

B6 Vs Stress: How B6 Protects The Brain
Most of us know how stress can affect our mood and energy levels during the day. However, handling stress isnt just about being mentally strong enough. Chronic or long-term stress can actually change the brains biology and make us more vulnerable to conditions like depression and anxiety.
Vitamin B6 is arguably the most important B vitamin for mental and brain health because it is critical for making neurotransmitters and can help minimize the harmful effects of stress, including:
-
Psychological effects of stress: B6 helps produce calming neurotransmitters, including serotonin and GABA. These neurotransmitters can help us feel more stable and less overwhelmed in the face of trauma or day-to-day stressors.
-
Biological effects of stress: Over time, stress hormones like cortisol can cause damage to the brain and body, resulting in problems including memory loss and stomach ulcers.
-
Physical toxins and infections: Animal studies have found that B6 may reduce brain inflammation and cell death and prevent memory loss associated with meningitis infection.
In order to effectively handle stress emotionally and physically, its important to have optimal levels of B6.
