Protein Powders


1. Do You Need Protein Powder to Build Muscle?
No supplement is required to build muscle, but protein powder is one of the easiest ways to hit a high daily protein target. Research consistently shows that eating enough total protein, combined with resistance training, supports muscle growth. Powder simply makes that protein convenient, affordable and portable.
2. Types of Protein Powder
| Type | Protein per Scoop | Digestion | Best For |
|---|---|---|---|
| Whey concentrate | 18 - 24 g | Fast | Value, taste |
| Whey isolate | 24 - 27 g | Fast | Lean gains, lactose sensitivity |
| Casein | 22 - 25 g | Slow | Before bed, between meals |
| Blend (whey + casein) | 22 - 25 g | Medium | All-day use |
| Plant blend (pea, rice, soy) | 18 - 24 g | Medium | Vegan, dairy-free |
| Beef or egg protein | 20 - 25 g | Medium | Dairy-free alternatives |
3. What to Look For in a Top Protein Powder
- At least 20 g of protein per serving and about 2 to 3 g of leucine
- A high protein-to-calorie ratio (around 75 percent or more of calories from protein)
- Transparent labels with no proprietary blends
- Third-party testing such as NSF Certified for Sport or Informed Choice
- A flavor and sweetener you enjoy
- Good mixability without clumps
- Cost per 25 g of protein, not just cost per tub
4. How to Use Protein Powder for Muscle Gain
Use protein powder to fill gaps in your diet. Most people building muscle aim for around 1.6 g of protein per kilogram of bodyweight per day (about 0.7 g per pound), spread across 3 to 5 meals. One or two shakes a day plus whole-food meals makes that easy.

Lactose-intolerant lifters often do well with whey isolate or plant protein. Vegans can choose pea and rice blends or soy protein. People on low-carb or keto diets should look for isolates with minimal carbs. Those trying to gain weight might choose a blend or mass gainer with extra calories.
6. Final Tip
Buy a small tub or sample first to confirm you like the taste and digest it well.
