Whether you’re a serious athlete, a weekend warrior or just a dedicated gym goer looking to tone-up, it's a good idea to have some powdered protein on hand. Protein builds muscle, boosts your performance and makes the most out of all your hard work in the gym. And thanks to the high protein content of powdered supplements, having a scoop or two in a shake, smoothie or bowl of oatmeal not only helps build and preserve lean muscle mass effectively, it also aids weight loss efforts by boosting calorie burn and increasing satiety. But when there are so many options on the market, from industrial-sized tubs to indie vegan brands, how is a guy supposed to choose the best protein powder for his needs? After all, not all protein powders are created equal. When looking for protein, the most important factors to consider are the amount of protein per serving, the presence of all essential amino acids, and the digestibility of the protein source, which indicates how well your body can absorb the nutrients; essentially, look for a protein with a good balance of essential amino acids and high digestibility. We sifted through the good, the bad and the ugliest tubs to unearth the ones worth your time.
