I don't think it will have a negative effect on weight loss, but I would be concerned about some of the ingredients like Aspartame (artificial sweetener associated with several health concerns http://www.mercola.com/article/aspartame/hidden_dangers.htm ), artificial colors and artificial flavors.
Emergen-C is a healthier alternative.
I usually mix a pack with at least 16 oz of water, and sometimes with a quart of water. It actually doesn't taste that watered down to me.Just a quick question having to do with the Emergen-C...each packet has 1000mg of vitamin C, and each packet is to be mixed with only 4 - 6 oz. of water according to the instructions. Does anyone try mixing one packet with 20oz bottles of water, is it watered down tasting? Also, if you wanted to have several packets (or mix several packets to fill a 20oz container), can that much vitamin c have an adverse affect?
