If other vision-enhancing supplements besides Vision Essentials Ultra are used, would it still be advantageous to add saffron to the others? Is that particularly helpful, as clinical research supports using saffron for promoting retinal health?

We see saffron as having significant benefit, so this is a strategy that could be considered if there is a sense of one of the others being preferential. To then find a generic source of saffron and add that to the regimen would be a way to get the best of both choices.
