Frequently Asked Questions
🔹Which protein powder is best for beginners in the UK?
For most UK beginners, a whey concentrate or blend offers the best mix of value and taste. Brands like Optimum Nutrition or MyProtein are popular for their consistent results and affordable prices. If you’re vegan or lactose-intolerant, go for a well-rated pea or rice protein with added BCAAs. Always check reviews for mixability and aftertaste.
🔹How much protein powder should I use per day?
General guidance is 20–40g per shake, 1–2 times per day as needed to reach your daily protein target (usually 1.2–2g per kg of bodyweight). Always factor in your dietary protein intake, and consult a nutritionist for specific goals.
🔹Is plant protein as effective as whey?
Plant protein blends can be just as effective as whey if you get enough total protein and amino acids. Look for products with added BCAAs or a blend of sources (pea, rice, hemp) to match whey’s full spectrum. Some athletes prefer plant protein for gut health or allergies.
🔹Can I use protein powder for weight loss?
Absolutely—protein powder can support weight loss by boosting satiety and helping preserve muscle during a calorie deficit. Choose low-sugar or unflavoured options, and don’t rely on shakes as your only meal.
🔹How do I know if a protein powder is good quality?
Check for UK/EU certifications, transparent labelling, high protein per serving (typically 18g+), and minimal artificial additives. Reviews and lab test results (where available) can further confirm quality.
🔹Are there any side effects of protein powder?
Most people tolerate protein powder well. Common issues include bloating (especially with lactose or sweeteners), and rare allergies. If you have a sensitive gut, try hydrolysed whey or single-ingredient vegan proteins. Always follow serving guidelines.
🔹What’s the difference between isolate, concentrate, and hydrolysed protein?
Whey concentrate is least processed, higher in carbs/fat, and most affordable. Isolate is more refined, usually >90% protein and lower in lactose. Hydrolysed is “pre-digested” for fast absorption and is ideal for sensitive stomachs or post-surgery recovery. Each type has pros and cons for different users.
🔹Can I mix protein powder with hot drinks or food?
Yes! Stirring protein powder into porridge, smoothies, or even coffee is a great way to boost protein intake. Just avoid boiling water, as it can cause clumping or affect texture—mix with cool liquid first, then add to hot foods.
