I don't see any issue with giving these 2 products at the same time.
I would like to reassure you that children may experience discomfort on a very frequent basis, but this does not affect their health or development. I suggest clockwise massage movements on the belly, knee bends or bicycle movements. I also invite you to hold him close to you (skin to skin), rock him, gently massage his belly, play a white noise (vacuum cleaner, application on smart phone or other), and cuddle him.
I also invite you to take a look at the colic section of Born and Grown here.
I remain available if you have any other questions, so don't lose hope :)
