I have purchased over 10+ bottles within the past 6 months, and I have referred to many friends and family because I had such good result. HOWEVER, the quality has gone down. Color change is one thing, but the last 5 bottles I've received has an awful smell. I couldn't take them because it smelled disgusting. I have purchased other turmeric supplements before, and have NEVER smelled such thing. They must have changed the formula. I messaged them before posting this review because giving a negative review without any communication between the buyer/seller isn't fair. However they just kept making up excuses and didn't even apologize once, and ended up ignoring my last message. Also, this product definitely is not a 100% money back guarantee, because I feel like they would have given me a refund, or send me replacements to make up for these low quality bottles.
