Choline, a precursor of acetylcholine

Why Choline Matters

Choline is an essential nutrient that keeps our brain functioning smoothly. Typically, our blood contains a stable amount of choline, about 10 picomolar (pM). However, eating foods rich in choline or lecithin can boost this level temporarily. On the flip side, not getting enough choline can drop these levels significantly.

What does choline do? Well, it’s crucial for building acetylcholine, a major brain chemical that helps our brain cells communicate, and for maintaining healthy cell walls.

Interestingly, choline has been a topic of research for years. In Europe, a form of choline called lecithin has been used as a medicine to help keep brain cells robust for over 50 years.

Research

Recent research explores whether boosting choline levels can help when brain pathways involving acetylcholine are damaged. This damage might make some brain cells too active, using up acetylcholine too quickly. Researchers think that adding choline to our diet might help slow this process down, potentially easing symptoms of diseases related to brain function.

However, proving this has been tricky. We used to think that the brain shields itself from the ups and downs of nutrient levels in our blood thanks to the blood-brain barrier—a kind of gatekeeper that controls what enters the brain from the bloodstream. But it turns out this barrier doesn’t regulate choline very well, which means the brain might handle choline levels differently, possibly outside this barrier.

In this discussion, we dive into how the brain might manage its choline levels and what this means for our health. Understanding choline can help us take better care of our brains and improve overall brain health.
