DMAE is an organic compound which is related to Choline, however differences in its chemical makeup allow it to cross the blood brain barrier more effectively.
What Is DMAE?
DMAE is an organic compound related to choline that can be naturally produced in the body. Structurally, the only difference between the two is the DMAE has 2 methyl molecules coming off of the nitrogen molecule while choline has 3. Because of this missing molecule, DMAE can cross the blood-brain barrier more easily, giving it more noticeable effects.
DMAE Dosage Information
People usually take a dose between 100 – 300 mg twice a day. Doses should be taken with meals. It is always suggested to start with a small dose and work your way up.
How Does DMAE Work?
Like choline, DMAE is a precursor to the neurotransmitter acetylcholine.  Acetycholine the only neurotransmitter used in the motor division of the somatic nervous system. It activates muscles in the peripheral nervous system and plays a very important role in our ability to sustain attention in the central nervous system. It also has a variety of effects as a neuromodulator upon plasticity meaning it affects our short-term memory and our ability to learn.
The difference is that DMAE crosses the blood-brain barrier more easily and its effects are much more noticeable.
Safety and Side Effects of DMAE
No studies have shown any serious negative effects associated with DMAE. At lower doses there are usually no side effects. At higher doses, people have reported experiencing headaches, drowsiness, anxiety, and twitching movements.
It is recommended that those suffering from schizophrenia or depression not take DMAE supplements.

If you are looking for a nootropic to take every day, or a nootropic to work with one of the “racetam” drugs, then I would recommend you go with a choline supplement instead. It will still provide the “racetams” with acetylcholine and it won’t have any effects that you will build up a tolerance to.
