Generally speaking, for most people, it’s a good idea. Mostly because we have trouble getting the nutrients we need to fully recover from an intense workout. A recovery shake or smoothie can help until you get actual food into your body.
That being said, be sure to have a doctor, nutritionist, dietician, certified health coach, etc., go over sound nutritional practices for you based on your current health and training objectives.
Oh, and I do have a recovery smoothie that is berry based on intense workout days =)
