If you're new to supplements, whey protein is usually the sensible place to start. It's simply a high-quality protein derived from milk, prized for its complete amino acid profile and how quickly the body absorbs it.
Why supplement with whey at all?
Most people can meet their protein needs through food, but doing so consistently is harder than it sounds — particularly if you train regularly, have a busy schedule or a smaller appetite. A shake is a convenient, cost-effective way to close the gap and support muscle recovery after training.
Blend or isolate?
A whey blend such as Applied Nutrition's Critical Whey or BioTechUSA's 100% Pure Whey combines whey concentrate and isolate. Blends offer excellent value and a creamier texture, and suit most people's daily use.
A whey isolate such as Applied Nutrition's ISO-XP is filtered further, giving you more protein per scoop with less fat, sugar and lactose. It's the pick if you're watching calories closely or find regular whey sits heavily.
There are also hydrolysed wheys like BioTechUSA's Hydro Whey Zero, where the protein is partially broken down for very fast absorption — popular with athletes training twice a day.
How to use it
One scoop mixed with water or milk after training is the classic approach, but total daily protein matters far more than timing. A shake also works well as a mid-afternoon snack or blended into porridge or smoothies.
What to look for on the label
- Protein per serving (around 20–25 g is typical)
- Allergens — whey contains milk by definition
- Third-party testing marks such as Informed Sport if you compete
