When should I supplement with a bar?      You should learn to use protein/nutrition bars as meal replacements, particularly when you don't have time for a wholefood meal. Bars can also come in handy as pre- and post workout meals, although protein shakes with simple carbs are the preferred solution. For those looking to keep lean you should look for a bar that has atleast 20 grams of protein and fewer than 3000 calories. Bars are an excellent nutritional aid and if you don't have time for a meal you should always consider a shake or bar to compensate. We suggest sticking to no more than 5-6 bars per week.
