Whey protein powder is a dietary supplement commonly used by athletes, fitness enthusiasts, and individuals looking to increase their protein intake. Whey is the liquid part of milk that separates during cheese production. It is full of beta-lactoglobulin, immunoglobins, and alpha-lactalbumin, which promote muscle building and aid in weight control. Whey protein powder is a complete protein, meaning it contains all nine essential amino acids that the body cannot produce on its own and must be obtained from food sources. It's highly digestible and quickly absorbed by the body, making it an efficient way to deliver protein to muscles after exercise for muscle repair and growth.

We reviewed the best whey protein powders on the market based on features like formula content, flavor(s), other nutrient content, and formula purity. The Opportuniteas Whey Protein Powder is the best overall pick on our list; keep reading to see the rest!

The Best Whey Protein Powder Buying Guide

A whey protein powder can work wonders on your muscles, making them stronger and more resilient. But to make the most out of this supplement, you need to get the perfect product for your fitness regimen. This comprehensive buying guide can help you weigh your options so you invest in a whey protein powder that meets your needs.

Benefits of Whey Protein Powder

  • Whey protein powder contains branched-chain amino acids (BCAAs) to improve muscle growth, decrease muscle soreness, and more
  • Glutamine, one of the major amino acids in whey protein powder, boosts muscle recovery and healing
  • It’s useful for diets like paleo and keto where your protein intake needs to be high
  • Whey protein powder facilitates bodybuilding and helps you get well-defined muscles
  • As whey protein powder increases your metabolism, cells consume more carbohydrates and break down fat

How To Choose a Whey Protein Powder

Size or serving

As you need to take whey protein powder regularly, you should get a product that can last for at least a month. For this, check the number of servings per container and the number of scoops you should add to prepare your ideal protein shake or smoothie.  If you consume the shake once a day, choose a product with 27 to 30 servings. On the other hand, if you use whey protein powder twice or more per day, you should choose a product with 62 servings or more.

Formula

The formula of a whey protein powder is the most crucial factor because it impacts its performance and benefits. Most products come with 100% whey protein while a few consist of a blend, like whey concentrate, whey isolate, and whey peptides. Most products have BCAAs, which are usually at a lower concentration than whey. Some options also include minerals like calcium, iron, sodium, and potassium for a balanced diet. While looking through the ingredients, ensure the whey protein is sourced from grass-fed cows as this is healthier and more effective than that obtained from artificial sources.

Safety

You should check if the chosen whey protein powder is free from GMOs, artificial sweeteners, and alcohol. These components make the product unfit for consumption and your health. If you have gluten intolerance, choose a product with no gluten. Similarly, the selected pack of whey protein powder shouldn’t have any artificial growth hormone since it behaves like a steroid and can disrupt regular homeostasis.

Flavor

Drinking unflavored protein shakes can be unappealing and make you feel nauseated. So, it’s better to choose a whey protein powder with infused flavors. For instance, if you love chocolate, get a product that tastes like it. If you want a protein that’s ideal for the morning, go for a product with coffee for extra energy. Peanut butter and vanilla are also popular flavors for whey protein powders.

Digestion and absorption

Your optimal whey protein powder should be easily digestible without impacting the GI tract and its functions. For instance, the product shouldn’t cause bloating or indigestion. You should also get a product with a higher absorption rate so that your cells can easily absorb the components.

How To Consume Whey Protein Powder

There are a variety of ways to incorporate whey protein powder into your diet. Some of them include:

  • The traditional method of mixing whey protein powder with water or milk to make a protein shake
  • If you don’t like plain shakes, you can add whey protein powder to smoothies, which is a great way to also enjoy fruits and vegetables for more vitamins and nutrients
  • Make delicious baked goods by adding whey protein powders to cake or cookie batter
  • For a healthy breakfast, add whey protein powder to oatmeal, along with some chopped nuts and fruits, or add it to pancake batter

Precautions To Follow 

Whey protein powder offers ample benefits if consumed appropriately. In case you take it more than recommended, you may experience side effects like acne, bloating, irregular bowel movements, headaches, and nausea. You should also avoid it if you are allergic to dairy products because whey protein powders are made from milk proteins.

FAQs

How often should I consume whey protein powder?
The frequency at which you consume whey protein powder depends on your fitness routine and health requirements. For instance, if you’re bodybuilding, you should take the supplement two or three times a day. But if you simply wish to make your muscles stronger for regular workouts, consuming it once a day will meet your needs.
Should I take whey protein powder if I have higher creatinine and uric acid levels?
No, you shouldn’t take whey protein powder if you have higher creatinine and uric acid levels. This is because after digestion, more amino acids will be released into your bloodstream and that can further increase your creatine and uric acid levels.
Is there any age restriction for consuming whey protein powder?
No, there’s no age restriction for taking whey protein powder. But you should consult with your trainer or doctor to better understand the appropriate quantity to consume based on your age, diet, and fitness regimen or goals.
