I have taken Preservision with Areds 2 for over 5 years and also take one in the am and one in the pm rather than 2 at the same time. I have never had stomach problems and wonder if spacing them out that way would lessen the effects of any stomach upset. I also happen to take one right before breakfast and dinner just as a reminder so that might help also.
I would love to receive free vitamins….they ain’t cheap but I am cagy about getting them at a good price.
It may help to take the supplement with your meals rather than on an empty stomach.
