Reflex 100% Whey is a whey protein concentrate powder delivering 21g of protein per 30g serving. Made from instantised, ultra-filtered whey concentrate (around 71% protein), it retains more of the natural nutrients found in whole whey — including healthy fats and bioactive peptides — for a creamier texture and richer taste than leaner powders. It's designed to support muscle recovery and growth after training.

100% Whey is a whey protein concentrate. Concentrate keeps more of the natural components of whole whey, giving it a fuller flavour and creamier texture at great value. Isolate (like Reflex Isolate Pro) is filtered further to strip out most of the fat, carbs and lactose, making it leaner and faster-digesting but less rich. Choose concentrate for a satisfying everyday shake; choose isolate for the leanest possible profile.

Yes. It provides a fast, high-quality source of all nine essential amino acids, including leucine — the key trigger for muscle growth. Training creates small tears in muscle fibres, and the 21g of protein per serving supplies what your body needs to repair and rebuild them stronger. Added digestive enzymes and friendly bacteria (LactoSpore®) help you absorb and use more of it.

Mix 30g (around one heaped scoop) with 200ml of water or skimmed milk, shake, and drink immediately. You can take 1–3 servings daily, ideally before or after training to support recovery — though a shake at any point is an easy way to hit your daily protein target. Use less liquid or full-fat milk for a thicker consistency.

100% Whey is suitable for vegetarians but not vegans, as whey is dairy-derived. It contains milk and soya (soya lecithin) and, being a concentrate, naturally contains some lactose — so it isn't suitable if you have a milk allergy or are lactose intolerant. It's made in a facility that handles other allergens and may contain traces of gluten and/or egg, so always check the pack if you have a serious allergy.

Yes. As a whey concentrate made from milk, 100% Whey naturally contains some lactose, so it isn't suitable for people who are lactose intolerant or have a milk allergy. If you're sensitive to lactose, a whey isolate such as Reflex Isolate Pro contains far less and may suit you better.

There is no added sugar in 100% Whey (the 1.8g of sugar per serving occurs naturally). It's also free from artificial colours. It is sweetened using sucralose and steviol glycosides from stevia

The Reflex Nutrition Shaker is hand-wash only. It should not be filled with hot or carbonated drinks, and should not be stored in the freezer. Rinsing with warm soapy water immediately after use is the most effective way to keep it clean and odour-free between sessions.

Yes. The shaker has measurements marked on the side, allowing you to accurately measure your liquid before adding powder. This is particularly useful when following specific serving instructions.

Yes. The shaker includes an integrated mesh that breaks down powders as you shake, producing a smooth, lump-free drink. It is designed to work with all types of protein drinks, whether mixed with water or milk, including thicker blends.

Yes. The Reflex Nutrition Shaker features a screw-top cap that is 100% leak-proof. Unlike push-fit or clip lids that can pop open under pressure, particularly when shaking vigorously, the screw-top design creates a secure seal every time, making it safe to carry in a gym bag, backpack, or car without risk of spillage.

The Reflex Nutrition Shaker is available in two sizes: a 500ml shaker priced at £3.49, and a 700ml shaker priced at £4.49. The 500ml size is well-suited for standard single-scoop protein shakes mixed with water, while the 700ml size offers more room for larger servings.

Creatine can be excellent for 50-year-olds. When combined with resistance training, a daily dose of creatine monohydrate can be highly effective at fighting age-related muscle loss, improving bone mineral density, and boosting cognitive function like memory and brain fog.

While creatine monohydrate is one of the safest and most researched sports supplements for healthy adults, it is not suitable for everyone. Consult a doctor first if you have pre-existing health conditions.

Creatine Monohydrate is tasteless and mixes easily into water, juice, or a protein shake.

Take 3–5g daily to maintain muscle creatine saturation. Mix each 1g with at least 100ml liquid. Consume immediately after mixing. Take daily, even on rest days, to keep your stores topped up.

This product is a food supplement and should be used in conjunction with a varied and balanced diet and a healthy lifestyle, not as a substitute for such. Do not exceed the stated daily dose. Not intended for use by anyone under 18. Keep out of reach of young children.

Creatine monohydrate is a supplement that saturates your muscles with phosphocreatine. This helps your body rapidly regenerate ATP (the primary energy currency of cells) during intense, short bursts of physical activity.
