Eggs are a good source of several nutrients tied to brain health, including vitamins B6 and B12, folate and choline ( 63).

Choline is an important micronutrient that your body uses to create acetylcholine, a neurotransmitter that helps regulate mood and memory ( 64 Trusted Source,  65 Trusted Source).

Two studies found that higher intakes of choline were linked to better memory and mental function ( 66 Trusted Source,  67 Trusted Source).

Nevertheless, many people don't get enough choline in their diet.

Eating eggs is an easy way to get choline, given that egg yolks are among the most concentrated sources of this nutrient.

Adequate intake of choline is 425 mg per day for most women and 550 mg per day for men, with just a single egg yolk containing 112 mg ( 64 Trusted Source).

Furthermore, the B vitamins have several roles in brain health.

To start, they may help slow the progression of mental decline in the elderly ( 68 Trusted Source).

Also, being deficient in two types of B vitamins — folate and B12 — has been linked to depression ( 69 Trusted Source).

Folate deficiency is common in elderly people with dementia, and studies show that folic acid supplements can help minimize age-related mental decline ( 70 Trusted Source,  71 Trusted Source).

B12 is also involved in synthesizing brain chemicals and regulating sugar levels in the brain ( 69 Trusted Source).

It's worth noting that there's very little direct research on the link between eating eggs and brain health. However, there is research to support the brain-boosting benefits of the nutrients found in eggs.

SUMMARY:Eggs are a rich source of several B vitamins and choline, which are important for proper brain functioning and development, as well as regulating mood.
