Rating one star simply because to use this I have to create an account on Tile's servers. This should not be necessary and with the current rate of data breaches is yet another potential security issue with my e-mail address plus having to create yet another password.

Niacin is a water soluble vitamin and is not "stored" in your body so complaints of 300% niacin in Spark is BAD apparently should read up on water soluble vitamins!

Here's what I liked about the challenge...it is a great platform to change your diet, eat clean, and exercise regularly. I like the spark drinks and the catalyst. The meal replacement shakes are pretty tasty. What I don't like...so.many.pills! I was fine during the cleanse, but as soon as the max phase started, the supplement counts increases markedly and I was so nauseated. Like puking my guts out. No matter how I took them (with meals without meals, before or after exercise) I was so sick. I quit with 7 days left because if the nausea. Was it worth the money? No. Eat clean, exercise, and don't drink and magically you will lose weight.
