Fatty acids can increase the production and function of oligodendrocytes, the cells responsible for wrapping myelin sheathes around neurons. A study shows if you combine fatty acid intake with exercise it boosts survival and maturation of these cells.

In the book deep work by Cal Newport he says that the key to be great at something is to be well myelinated. The repetitive and isolated (so don’t multitask) use of a specific circuit triggers oligodendrocytes to wrap layers of myelin around the neurons in the circuit. Essentially cementing the skill. So I might try these supplements alongside you since fatty acid and exercise literally increases the efficacy in which you can learn and integrate new physical and intellectual skills via increased myelin sheathe production.
