Shedding Light on the Effect of Fish Oil Supplementation on Dark Adaptation Capabilities

10 December 2019, Version 1
This content is a preprint and has not undergone peer review at the time of posting.


This is the first study to directly relate the uptake of fatty acids from fish oil supplements (as measured by blood analysis) to changes in dark adaptation capabilities. During the dosing and abstention phases of the regimen, the rise and fall in blood levels of the acids is mirrored by a reversible increase in perception capabilities.
