Kourtney Kardashian

Reality TV personality Kourtney Kardashian tries to stick to a healthy diet, which she enjoys alongside apple cider vinegar drinks, probiotics and other supplements. "Every morning, when I wake up, I take collagen supplements on an empty stomach. About 20 minutes after the collagen, I usually drink one tablespoon of organic apple cider vinegar mixed into a glass of water. Both of these habits have a ton of health benefits that affect everything from your skin to the way your body processes nutrients," Kourtney said on her official application.
