This was my first time using this collagen formula. The chocolate has one extra ingredient for cellulite that the flavorless doesn't. But whatever the case, this is actually reducing my cellulite! I broke my foot & couldn't hike for 9 months. So my legs looked terrible. I was just starting to walk and then hike again, when I tore my calf muscle. So, now I'm debilitated again. But luckily I found this product because it has visibly reduced the cellulite on my upper legs, and it's starting to reduce the cellulite around my knees. I'll keep using it if I can get a better price. $59.99 is a little bit pricey.
