Whey Protein: What It Actually Is, And Who Actually Needs It
The most popular supplement in every gym bag. Here's what it does, and whether you're actually one of the people who needs it.
Help break down specific macronutrients — proteases for protein, lipases for fat, amylases for carbohydrates — supplementing the enzymes the body already naturally produces in the digestive tract.
Specific diagnosed conditions like pancreatic insufficiency, or lactose intolerance (where lactase supplementation is well-established), show clear evidence for enzyme supplementation providing real benefit.
General 'digestive support' marketing aimed at otherwise healthy people without a diagnosed enzyme deficiency has considerably less evidence behind it — occasional bloating or discomfort often has other causes worth investigating first.
Eating too quickly, food intolerances, high-FODMAP foods, or simply overeating are all far more common causes of digestive discomfort than an actual enzyme deficiency — worth ruling these out before turning to supplementation.
