Dietary Supplements and Breastfeeding

Hi, I'm 36 weeks pregnant with twins and next week I have a schedules c-section. Right now I'm 87 lbs overweight all together including excess weight I had from my first pregnancy. I'm planning on breastfeeding while I try to lose weight. I have come accross these dietary supplements that seem like they would be effective. One of them is Colon365 cleanse System which is an a set of all natural supplements that cleans out your system of excess weight.

The Colon365 system consists of the following products:

I want to post this question in one of the doc. to patient forums but I don't know which one to post it in. I'm really desperate to get back to my pre-pregnancy weight but I don't want to try a crash diet.

One supplement that worked for me when I was in high school is Noni Juice which is an antioxidant, here's their website: http://glacialmilk.net/products_noni.htm

As much as I want to lose weight, I want to be able to breastfeed since I know that's best for them. I breastfed my one-year-old daughter for 9 months and she is very healthy. Thanks.
