Does drinking a protein shake after training build muscle? Here’s the science

When's the best time to gulp down your protein shake?

Research continues to reveal how increasing your protein intake can help you build muscle. Protein plays an important role in muscle synthesis and provides the building blocks or amino acids needed for building and repairing muscle tissue. That being said, when we dive into the details or nuances here, some powerlifters start asking questions like: when is the best time to drink my protein shake? Will I boost my muscle-building results if I drink my protein shake right after training? Let’s look at the research.

The timing of protein intake

Researchers concluded that the timing of protein intake immediately after resistance training doesn’t impact muscle strength, power, or body composition changes. In other words, drinking your protein shake right after that workout won’t give you an extra boost compared to drinking it some other time. However, drinking your protein shake right before your workout could lead to digestive upset.

What about the anabolic window?

The anabolic window theory refers to the short time frame of about two hours after a workout when some people believe your muscles better absorb nutrients, which enhances muscle growth and recovery. Researchers have found that there isn’t a specific anabolic window, and increasing protein intake throughout the day is most beneficial.

Spread throughout the day

Rather than trying to rush to gulp down your protein shake the second you put down the weights, researchers recommend spreading protein intake throughout the day, which has been associated with improved body composition and athletic performance. When compared to other eating patterns, getting 20-40 grams of high-quality protein every three to four hours yielded the most beneficial effects on muscle protein synthesis rates. 

The potent combo of weightlifting and protein

Research shows that combining weightlifting or resistance training with increasing your protein intake promotes strength and muscle mass gains. If you continue to stick with it, you should see the results of your efforts over time. You can drink that shake within two hours of working out if you’d like, but there’s no need to rush minutes after your workout session ends.

The beet boost: Here’s what science says about drinking beet juice pre-workout
Gulping down just a few ounces of this colorful juice before your workout could combat fatigue, enhance endurance and muscle power, and more.

I’ve always liked beets, from the sweet yet slightly zesty flavor to the array of vibrant colors. You can find colors like deep royal purple, red, golden yellow, and white beets. Betanin is the natural pigment that’s responsible for the red color of beets. This pigment has strong antioxidant properties.

One of my favorite healthy nutritional approaches to help manage autoimmune disease is the Wahls Protocol, created by Dr. Terry Wahls to tackle her own multiple sclerosis. As Dr. Wahls says, “eat the rainbow”, and she doesn’t mean Skittles; she means bright, colorful fruits and veggies, like beets. These deeply pigmented, colorful foods are anti-inflammatory, rich in antioxidants, and provide numerous health benefits, including helping to protect against chronic diseases like heart disease.

The classic bench press is a go-to exercise for those looking to build bigger and stronger arms and pecs. The bench press is a compound exercise that deserves a spot in your upper-body training routine. This move targets your large pectoral muscles that help you perform the pushing motion, and researchers revealed that bench pressing also helps you increase strength and performance in other moves like push-ups, as well as improving your posture.

One of the more commonly discussed and debated topics relating to the bench press is the ideal number of sets and reps to optimize muscle growth. Most people are looking to incorporate progressive overload and increase the weights over time to promote hypertrophy. Is there an ideal range of sets and reps to maximize gains? Recently, researchers explored just that.
