2. CDPCholine - Acetylcholine is one of the brain’s primary neurotransmitters. If your brain is running low on Choline, you’re simply not going to be functioning well. A lot of different nootropics are based around choline, whether they’re choine supplements (adding to the amount of choline available) or affecting the interactions of choline in the brain. Some nootropics focus on preventing the breakdown of choline in the brain, which effectively increases the amount of choline available. CDPCholine is a choline supplement, so it increases the amount of choline available to the brain. It is important to take a choline supplement such as CDPCholine with racetam drugs, since these drugs seem to cause the brain to use up choline at a higher rate. Check out the CDP choline page.
