No adverse effects but seeing any changes requires patience.
I write this after finishing the 30-day supply of these skin-filter blemish clearing supplement pills and the most positive thing I'll say about the product and my experience is that it didnt cause me any adverse health effects and didn't do anything to my stomach either. As for my skin, I'm just not sure. i didn't see any major difference during the process but a daily dose of Vit A, C, and zinc doesn't hurt (especially if you're not already taking a daily multi-vitamin) Granted, you can get those particular nutrients plus more in a cheaper supplement. Overall, this is a decent enough skin-clearing supplement, though I don't know if I'll continue past this first month.
