Your Guide to Protein Supplements

Walk into any supplement store and the protein aisle is enough to make your head spin: whey concentrate, whey isolate, casein, plant blends, egg protein, beef protein... Each one claims to absorb faster or build more muscle. But it doesn't need to be that complicated.

The stuff is just concentrated protein from milk, eggs, plants, or beef. Your body breaks it down into amino acids exactly like the protein in your food, using them for everything from repairing muscle to making enzymes and hormones.

What makes one protein better than another

The quality of a protein powder isn't about the brand, but about how much of the nine essential amino acids it contains—the ones your body can't make on its own. Leucine matters most because it switches on muscle building, but you still need all nine to actually build anything.

So don't fixate on the BCAAs promised on the label. Look at the full amino acid profile.

Do you actually need a protein powder?

The short answer is no. If you're getting enough protein from food—about 1.6 to 2.2 grams per kilogram of body weight, or 110 to 150 grams for a 70-kilo person—you're set.

Whole foods also have real advantages: they're more filling and carry along vitamins and fibre. But if you regularly fall 30 grams short at the end of the day or you're traveling, busy, or lacking appetite, a shake is the easiest way to fill that gap.

Choosing one isn't hard

Whey is the best starting point for most people: high quality, rich in leucine, backed by decades of research. Concentrate or isolate comes down to lactose tolerance and calories. Casein digests slowly, making it a good option before bed. Plant proteins are better than their reputation—just eat a little more or blend sources like pea and rice. Egg protein is a solid dairy-free choice. Beef protein needs label reading: its amino acid profile can look more like collagen than steak. And collagen itself isn't for building muscle anyway; it's a different tool, aimed at joints.

What matters more than choosing the 'perfect' powder is consistently eating enough protein every day. Protein powder doesn't replace good nutrition—it just makes one of the most important parts of it a whole lot easier.
