Effectiveness. At the end of the experimental period, neuroprotective effect of astaxanthin was determined via electrophysiological measurements of visual evoked potentials (VEP) together with the assessment of retinal apoptosis and oxidative markers expression. Astaxanthin helps to protect against typical oxidative stress to the joints, to promote healthy mobility, flexibility, and movement.
