Cerys,
Thank you for your post- you make a great point.
From personal experience, my generic pills look different every time I pick them up from the pharmacy!
It is definitely concerning what manufacturers are using to create these pills other than the active ingredients.
This information should be readily disclosed and if it is not, it might be worth calling the manufacturing company.
Thanks for being part of our community.
Best,
