How to use

Mix 1 serving (30 g) with 150–200 ml of cold water or milk, or add it to yogurt or oatmeal. Take 1–2 servings daily, after training or between meals. The exact time of consumption is not crucial – what matters more is reaching your total daily protein intake goal, not the specific time of day you consume it.

Suitable for

Recreational exercisers and athletes – for an easy way to increase daily protein intake
People on a diet – to help maintain muscle mass
Vegetarians – as a replacement for protein from meat
Yes, that's exactly what it's designed for. General guidelines recommend around 0.8 g of protein per kilogram of body weight per day for less active adults, while recommendations rise to about 1.2–1.6 g/kg for recreational exercisers, and up to 2.2 g/kg for serious athletes (Jäger et al., 2017). If it's hard for you to reach your target through food alone – say, because you don't have time for a large meal or you don't like meat – one serving (30 g, 22 g of protein) nicely fills the gap. However, it's not a substitute for an otherwise balanced diet, but rather a practical supplement.
No, this is one of the more widespread myths in fitness. The idea of an 'anabolic window' was popular for a long time, but more recent research shows that your total daily protein intake is more important for long-term results than the exact timing of consumption (Morton et al., 2018). You can safely drink your shake an hour or two after training, or even at your next meal – what matters is reaching your goal over the course of the whole day.
No, and this is a common fear, especially among women. Consuming protein alone doesn't increase muscle mass – that depends primarily on training (especially strength training) and total energy intake. Protein powders are not a hormonal product and don't contain steroids; they are simply a source of building material that the body uses if you give it a reason to, i.e. training.
Because it contains all 9 essential amino acids, which the body cannot produce on its own and must obtain from food – which is why it's considered one of the highest-quality protein sources. Of course, you can get the same from eggs, meat, fish, cottage cheese or legumes – protein powder is simply a quick and convenient choice for days when classic sources run out or you're short on time to cook.
Contains milk. May contain traces of eggs, gluten, soy, peanuts, tree nuts and fish.
If you are lactose intolerant, try the product with caution, as it may still contain small amounts of lactose despite the added lactase.
If you have kidney disease, consult your doctor – a high protein intake places additional strain on the kidneys.
