For months now I've been looking for healthy ways to get more calcium into my family's diet and to keep our digestion on track. So when I got some coupons that could be used for free servings of Dannon Activia, which contains a special culture that could help with digestion, it seemed like fate. I've decided to take this opportunity to participate in Activia's 14-Day Challenge to find out if incorporating this yogurt into my daily diet will boost my nutrition and help me to feel better. I'll be keeping all of you posted! In the meantime, you can find out get your own Activia coupons (yay!) by clicking below.
