Protein is an essential macronutrient needed to repair, recover, build muscle, and perform other vital physiological processes. Based on the most recent body of literature, the optimal daily amount of protein for those wanting to maximize muscle growth is between 1.6ā2.2 g/kg/day (~0.8-1.0 grams/lb/day).[1]
If youāre a 200lb guy thatās relatively lean, consuming 200 grams of protein from whole foods alone is quite challenging, which is where protein powders come in handy. Not to mention, when youāre traveling or on the go, high-quality protein sources are hard to come by, which is one of the reasons why protein shakes are so popular.
Although you can buy ready-to-drink protein shakes from convenience stores, gas stations, and grocery stores, they are a lot more expensive than buying a 2lb or 5lb tub of protein powder and mixing it yourself.
Because itās quite common for people to pre-mix their protein shakes but not consume them straight away, one of the most commonly asked questions in regards to protein powders is, āhow long does a protein shake last after mixing?ā. Not to mention, some people prefer to mix their protein with greek yogurt or oats (i.e. overnight oats, smoothies, etc.) for a quick and easy meal.
The answer to this question depends on various factors such as what the protein powder is mixed with (milk or water), whether itās refrigerated or left at room temperature, and if there are any other active ingredients added to the protein powder. In this article, we cover various protein powder scenarios and give you estimates of how long the mixture or protein shake will last.
