When to Take Whey Protein to Build Muscle 

Protein is essential for building muscle. 

If your goal is to increase muscle size and strength, you need to consume more protein than your body breaks down naturally during resistance training or weight lifting.

The optimal time to consume protein for optimal muscle growth is a widely-debated topic. 

Gym Goers often suggest taking a protein supplement 30–60 minutes after exercise. This is said to be the perfect time for getting the most out of a whey protein supplement and is often called the “anabolic window.”

The latest research suggests that the “anabolic window” may be much wider than 60 minutes. The International Society of Sports Nutrition recommends taking whey protein up to two hours after your workout to best support muscle growth.

Most people looking to build muscle don’t need to worry about the timing of protein intake if they are consistently doing resistance training and consuming enough protein. However, for certain types of athletes like bodybuilders, nutrient timing may be more important. 

If you train in a fasted state (like before eating breakfast), taking whey protein immediately after a workout may be beneficial because you haven’t consumed any protein since before bedtime.

Best Whey Protein Time for Preserving Muscle

Preserving muscle mass is especially important as you age. Studies show that people lose about 3–8% of their muscle mass each decade after age 30. Muscle loss is associated with a higher risk of fractures and premature death. 

Experts suggest that spreading protein intake evenly throughout the day is the best way to preserve muscle mass. To prevent muscle loss, eat 25–30 grams of protein per meal. If you have difficulty consuming this much protein, a whey protein supplement can help you increase your protein intake. 

Try adding a whey protein supplement at breakfast or with snacks between meals.

Exercise Performance and Post-Workout Recovery 

Many athletes take whey protein to improve performance and enhance post-workout recovery.

Endurance athletes should combine protein with a carb source during and after exercise. This may improve performance and reduce muscle soreness

Whey protein can improve both performance and recovery in strength training, regardless of whether it’s consumed with carbs.

For most people, getting enough protein is more important than when they consume it. However, strength and resistance training athletes should take whey protein either immediately before or after a workout.

When to Take Whey for Weight Management 

Protein is an incredibly helpful nutrient for fat loss. Consuming a high-protein diet may promote increased metabolism and control appetite. 

Protein helps reduce your appetite by lowering levels of the hunger hormone ghrelin, and increasing levels of appetite-reducing hormones like glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and cholecystokinin (CCK).

Eating a high-protein snack between meals may increase feelings of fullness and decrease your overall caloric intake for the day. 

A study found that people who ate a high-protein snack in the afternoon ate fewer calories at dinner, compared to those who ate a carb-based snack without protein. 

The snacks all provided the same number of calories, however, the snack eaten by participants who consumed fewer calories at dinner contained more protein. 

To promote weight management, eat plenty of protein-rich foods throughout the day. Drink a whey protein shake with a snack between meals to curb hunger and reduce caloric intake later in the day.

Whey Protein for General Health and Well-being

Adequate protein intake is essential for general health and well-being. Dietary protein serves many functions in your body. It helps repair and build tissues, drives metabolic reactions, regulates pH and fluid balance, and supports a strong immune system. It also transports and stores nutrients and can act as an energy source.

The daily recommended intake of protein for healthy adults is 10% to 35% of your total calorie needs. A person who consumes a 2000-calorie diet could eat 100 grams of protein, or 400 calories from protein, which would supply 20% of their total daily calories.

For general health and well-being, a whey protein supplement can be taken at any time to fulfill your daily protein needs. 

Is it OK to Take Whey Protein at Night?

Whether your goals are to build muscle, increase strength, improve exercise performance, or enhance recovery, you can benefit from taking whey protein before bed.

Researchers have found that taking protein before bed can promote muscle growth and recovery. It can also be helpful for older adults who wish to preserve muscle mass. 

This is because protein taken before bed is completely digested and absorbed, which increases the availability of protein to muscles for recovery during the night.

While you can take whey protein before bed, you may consider taking a casein protein supplement instead. Casein is more slowly digested and absorbed, which provides the body with a steady supply of protein throughout the night. 

How Much Whey Protein Per Day

Whey protein should be used to supplement the protein you’re consuming from your diet, not replace it. A whey protein supplement is easy to add to your diet. It comes in a powder that can be added to smoothies or yogurts, or simply mixed with water or milk.

Common dosages range from 25-50 grams per day (1-2 scoops), but some products will include other suggested serving sizes on the labeling.

Keep in mind that consuming excessive protein is not beneficial. Consuming too much protein may cause digestive problems, including:

  • nausea
  • pain
  • bloating
  • cramping
  • flatulence
  • diarrhea

Whey protein supplements are well tolerated by most people when consumed in moderation. 

Whey Protein Isolate vs Concentrate: Which Should I Pick?

There are two common forms of whey protein: whey isolate and whey concentrate.

Whey isolate undergoes different processing than whey concentrate, which makes the isolate higher in protein with fewer carbs and fat per serving.

The nutritional differences between whey isolate and whey concentrate are small, and there is little evidence that suggests one is better than the other. 

Whey isolate may be a good choice for people who want to limit their fat and carb intake. It may also be a better choice for people who are lactose intolerant. 

Both types of whey are gluten-free

Regardless of which kind you use, whey is a high-quality complete protein that can help you reach your daily protein intake goals.
