How to Compare Protein Powder Brands for the Best

Protein powder brands vary by calories, protein content, sweetener and additional vitamins and minerals that may help with absorption. Athletes typically opt for whey protein, derived from milk, while those with allergies, intolerances or diet preferences may prefer soy proteins.

Comparing Calories

• If the protein powder is for weight gain and building muscle, calorie intake may be considerably high. Many brands offer a lean option with lower calories, but still a significant amount of protein, which may be better for those watching their calories or trying to keep calorie intake within a certain range, as well as for those who do not wish to bulk up or gain weight. Additionally, consider how the protein powder will be used. If mixed with water, then the calories on the container are all that the person consumes, but if the powder is mixed with milk, juice or another beverage, then the calorie intake is higher. The calorie content should be considered with the purpose for taking the protein powder--low calories for protein supplement and weight loss, high calories for weight gain.

Protein Content

• The average person cannot actually digest much more than 25 to 40 grams of protein in one sitting. This can change depending on the amount of muscle built on the body, and the timing of protein consumption. Purchasing a protein powder with more than 40 grams per serving may be wasting it. Alternatively, the person could use half-size servings and double the length of time the protein powder lasts.

Sugar vs. Sugar-Free or Alternatives

• Some protein powders are made with sugar, which can provide a significant number of empty calories. If you're watching your calorie intake, or if you wish to avoid blood sugar spikes, opting for a sugar-free or fructose-sweetened protein powder may be best. If the protein powder is consumed immediately following a strenuous workout, the sugar or fructose may help the body recover faster.
