Is there any natural water weight pill I can take for instances like mother nature or just to start taking with my other vitamins? And what kinda vitamins does everyone take

There are lots of pills on the market called "Water pills" that act a a diuretic and help reduce water weight. But you need to be careful not to dehydrate yourself. Usually your body is retaining water for a reason (like to heal muscles after a workout).

As for vitamins: I take Vitaleph Bariatric Multivitamin (bought direct from their website). A generic of Citrical Maximum +D3 (from my grocery store). A B12 spray (from Amazon). Insync probiotic (grocery store). Those are the supplements my nutritionist recommended.

In addition I take: Vitamin C, coq10, Omega3, Vitamin E, and Beef Gelatin. The C, E, and Gelatin are all supposed to help improve skin elasticity so I don't have as much loose skin as I lose weight. The CoQ10 is for my carpel tunnel (recommended by my PCP). And the Omega 3 is just because I don't eat fish and don't get much Omega 3 any other way.
