Question Title

Text

As we grow older, we tend to become more forgetful. However, memory problems and difficulties in concentrating can happen at any age. Common causes include lack of sleep, depression, stress, anxiety, allergies, and hormonal imbalances. Poor nutrition is often thought to cause memory problems; a healthy diet can help improve memory. Gentle exercise increases the flow of blood to the brain and also may help to improve brain function.

Vitamin B-1 -- needed to produce the brain chemical acetylcholine, crucial for concentration levels and memory (50 to 500 mg daily)
Vitamin B-3 -- essential for brain health

Vitamin B-12 -- needed to create the myelin sheath that protects nerves and speeds up the rate of electrical transmission (100 to 1,000 mcg daily)
