Choosing a protein powder that fits your routine
Protein is one of the three macronutrients in food, next to fat and carbohydrate. Your body breaks it down into amino acids and uses them to renew tissue, including muscle. Protein contributes to a growth in muscle mass and to the maintenance of muscle mass. It also contributes to the maintenance of normal bones. A powder does nothing that eggs, fish or lentils cannot do. It is simply quicker and easier to measure, which is why it sits inside our sports nutrition range.
The forms differ more than the tubs suggest
- Whey concentrate: the least filtered form. It keeps some milk sugar and fat, and usually costs the least per gram of protein.
- Whey isolate: filtered further, so most lactose is removed. Lighter texture, and often easier if dairy sits heavily with you.
- Casein: thickens in the stomach and digests slowly over several hours. Many people use it in the evening or before a long gap without food.
- Plant blends: usually pea with rice, soy or pumpkin. Two sources together cover the amino acids that pea alone is low in.
- Clear whey and bottled shakes: light, juice-like drinks. Convenient rather than cheap.
One number on the label tells you more than the flavour list: protein per 100 g. A tub with 70 g per 100 g and a tub with 90 g per 100 g look identical on a shelf, yet the second gives you a third more protein per scoop. Compare that figure first, then the price per kilo. If mixing a shake is the step you keep skipping, ready-made protein drinks solve a practical problem, not a nutritional one.
How we choose the protein we stock
We look at three things: the form, the protein per serving, and whether the extras earn their place. We prefer tubs that state protein per 100 g, because that is the only fair way to compare price. With plant protein we carry blends of two or more sources rather than pea on its own, since a single plant protein is usually short on one or two amino acids. We buy directly from the brands, so what arrives is authentic, and our compliance team checks every label before a product goes live. You can read how we select brands.
Who protein powder suits, and what to expect
It earns its place when your daily total is hard to reach: you train several times a week, you eat plant-based, your appetite is small, or you are older and want to hold on to muscle. Be honest about the limits. Added to a diet that already contains plenty of protein, a shake mostly adds calories. Nothing in a tub replaces consistent training or sleep.
Give a new routine four to six weeks before you judge it, and judge it on the whole picture: strength in the gym, how full you feel, whether you actually enjoy drinking it. Taste and texture decide whether the tub gets finished, so start with one flavour before buying in bulk. If you train for strength and want a second, well-studied addition, creatine monohydrate is the usual next step.
Frequently asked questions
Protein powder is a concentrated protein made from milk (whey or casein) or from plants such as peas, rice and soy. It is food in a convenient form, not a medicine. It suits anyone who finds their daily protein target hard to reach: people training several times a week, plant-based eaters, people with a small appetite, and older adults who want to keep muscle. Protein contributes to the maintenance of muscle mass. If your meals already cover your needs, a powder adds convenience rather than results.
