WHEY PROTEIN ISOLATE - VANILLA

A 2018 systematic review and meta-analysis in Nutrients pooled 13 randomised controlled trials in young, healthy adults. Taken together, whey protein showed small-to-moderate effects on how quickly muscle contractile function returned in the 24–96 hours after resistance training — but only half of the individual studies reported a benefit, and the authors call for more research.

That is the evidence as it stands, not a promise. One scoop of this product provides 19 g of protein.*

A 2011 study in the American Journal of Clinical Nutrition gave eight adults a 10 g essential-amino-acid drink during an hour of cycling, once with 3.5 g and once with 1.87 g of leucine. Muscle protein synthesis measured during recovery was 33 % higher with the leucine-richer drink.

Eight participants, one exercise session, and a drink that is not this product. This product's label does not state a leucine amount, so we make no comparison.*

A 2018 meta-analysis in the British Journal of Sports Medicine pooled 49 randomised controlled trials with 1,863 participants who did resistance training for at least six weeks. Protein supplementation added on average 2.49 kg to one-repetition-maximum strength and 0.30 kg of fat-free mass. The effect was smaller with increasing age, and additional protein made no further difference once total intake reached about 1.6 g per kilogram of body weight per day.

One scoop provides 19 g of protein — part of your daily intake, not a substitute for training or a varied diet.*

A 2017 meta-analysis in Clinical Nutrition ESPEN combined eight publications. Over longer periods, whey was associated with a small reduction in a combined appetite score (4.13 mm on a visual scale); in the short term there was no significant reduction, and whey did not differ significantly from carbohydrate.

A small, inconsistent change in a questionnaire score is not an appetite or weight claim, and we make neither.*

A 2017 meta-analysis in the Journal of the American College of Nutrition pooled nine randomised controlled trials of whey protein in overweight and obese adults and reported changes in body weight, fat mass and some cardiovascular risk factors. The authors say more work is needed on dose and duration.

Those trials studied people with overweight or obesity — a medical situation, not what this product is for and not a claim we make.*

A 2021 meta-analysis in the British Journal of Nutrition combined ten studies with 596 participants. Whey protein supplementation was associated with an average 0.91 kg increase in lean body mass, with no significant change in fat mass, body weight or body-fat percentage; soy protein showed no significant change in any of these measures.

Those are averages across different trials, doses and training programs, not an outcome we promise. One scoop of this product provides 19 g of protein.*
