Can I take L-lysine, Vitamin B12, Vitamin C, and a liver cleanse at the same time without complications?

I have chronic hives, and I have recently learned that people have had success using one or more of these pills so I decided to give it a try. Most of these (except maybe the liver cleanse) seem like natural vitamins, but I feel like I'm popping a LOT of pills a day and just want to make sure it's okay. I'm taking 1000 mg L-lysine twice daily, 1000 mg Vitamin C once daily, 500 mg B12 once daily, and the liver cleanse is 2 pills twice daily between meals. Is this okay?
