Aragon notes, though, that the average protein intake of the participants was low for an active person (about 0.5 grams per pound of body weight) and protein supplementation brought that intake up to maximal levels (about 0.8 grams per pound of body weight).

Your body takes time to break down the fat and protein in order to absorb it, so the nutrients don't reach your muscles for a while after eating. With protein shakes, on the other hand, you can get fast-acting proteins (whey protein chief among them) that are easily absorbed into your body with little to no wait time. You can also find proteins that are absorbed slowly into your body, giving you a steady supply of amino acids overnight or all day long.

Eat 25 to 40 grams of protein within one to two hours pre-and post-workout. Basically, “time your workout between protein-rich meals and you’ll cover all your bases,” says Aragon. Some options: a scoop of whey protein powder mixed with water, 1 ½ cups Greek yogurt, one cup of cottage cheese, or 4 to 6 ounces of chicken or pork.

Here are three truths you need to know about protein timing: 1. The “magic window” is longer than you think. Some experts say that you should consume protein 20 minutes post-exercise, while others claim it’s an hour. The reality: You’ve got longer. Studies show muscles’ elevated sensitivity to protein lasts at least 24 hours, says Aragon.

Thanks to the amino acids in the proteins you eat, your body can repair and expand your muscle fibers--increasing the energy storage and thereby boosting strength, stamina, and endurance. A pre-workout protein shake will give your body a quick influx of amino acids, which will then be turned into ATP energy. When you hit the gym 60 to 90 minutes later, your muscles will be all powered up and ready to get through that workout. A mid-workout protein shake is ideal for those who are doing a workout longer than 60 minutes.

When you add those 209 grams from the protein drinks to the average 82 grams most adults already get from their daily diet, according to federal data, a 150-pound nonathlete would consume 291 grams of protein, or about five times the amount needed. An athlete could get nearly double.

Consuming excess protein through supplements can cause health problems. Often I see clients who are getting plenty of protein in their diets and then drinking three protein shakes on top of that, says Erin Palinski, a registered dietitian and certified personal trainer who has seen the ill effects.

What's in your protein drink. Here are the average amounts of metals we found in three servings of these protein drinks. The maximum limits for them in dietary supplements proposed by the U.S. Pharmacopeia are: arsenic (inorganic), 15 micrograms (µg) per day; cadmium, 5 µg; lead, 10 µg; mercury, 15 µg.

The body can only break down 5 to 9 grams of protein per hour, and any excess that is not burned for energy is converted to fat or excreted, so it's a ridiculous waste to be recommending so much more than you really need, she says.

Powders, bars and other supplements have become so ingrained in our culture that it’s hard to imagine not following up a great workout with a shake of some sort (and sometimes even mid-workout). Protein powder is, in many ways, leading the supplement charge.
