What are protein & protein powders? – The ultimate guide

Protein powders consist mainly of concentrated protein obtained from animal or plant sources. The most popular are milk-based products (whey and casein), but pea, rice or soy protein are increasingly finding their place in modern nutrition plans too. Each type of protein has its strengths: whey is digested quickly, making it ideal straight after a workout. Casein is absorbed more slowly and is suitable for a long-lasting supply – for example before going to bed.

Isolates and hydrolysates are refined versions: they contain more protein, less lactose and hardly any fat or sugar. Clear whey is the latest generation of these isolates – particularly refreshing and ideal for summer. For vegans, combinations of plant sources that ensure a complete amino acid profile are a good choice. Modern protein powders are not only functional but also come in a wide variety of flavours, and have long ceased to be just a “bodybuilder product”.

Buying protein & protein powder: what to look out for

When buying protein powder, you should keep a few points in mind. First: the composition. Does the product contain only high-quality protein, or has it been bulked out with cheap fillers? Then the protein content: a good guideline is over 80% protein. Digestibility also plays a role: if you are lactose intolerant, it's better to choose isolates or vegan protein.

Also important: additives. Artificial colours, flavourings or sweeteners can affect digestibility. Products with test certificates (e.g. the Cologne List) offer more peace of mind here. Also pay attention to the origin – made in Germany often means higher quality standards.
