With over a dozen different vitamins and minerals plus protein and carbs for energy, delicious Tiger's Milk have been a popular energy bar for decades. In fact, Tiger's Milk may have hold the claim of being the original energy bar. But that doesn't mean it has an old-fashioned nutritional profile. In fact the nutritional profile of Tiger's Milk bars is similar to that of the 40-30-30 and Zone concepts which were only introduced years after the original launch of Tiger's Milk Bars in the 60s.
