whey protein isolate + mulberry leaf extract

Whey protein isolate + mulberry leaf extract is a combination dietary supplement consisting of isolated whey protein (a highly purified protein fraction derived from milk) and mulberry (Morus alba) leaf extract. Whey protein isolate is distinguished by its high protein content with minimal carbohydrates and fats, and is used to support muscle protein synthesis, metabolic health, and satiety. Mulberry leaf extract contains bioactives, most notably 1-deoxynojirimycin (DNJ), which inhibits intestinal polysaccharide-degrading enzymes—reducing gastrointestinal absorption of glucose[2][3][4]. This combination is considered for improvement of postprandial glycemic control. Whey protein isolate acts primarily by **delaying gastric emptying** (leading to lower rates of glucose absorption after meals)[1][3], while mulberry leaf extract acts by **inhibiting alpha-glucosidase enzymes**, reducing the breakdown and absorption of dietary carbohydrates and thereby blunting postprandial glucose spikes[3][4]. Both ingredients have independent effects confirmed by randomized studies in healthy individuals and subjects with type 2 diabetes[1][3][4]. Timing is important for efficacy: whey protein isolate is most effective as a pre-meal supplement, and mulberry leaf extract works best when consumed with a meal[1][3]. The combination product is a **nutritional adjuvant** (not an approved pharmaceutical drug), explored for postprandial glycemia management and potential reduction of diabetes risk.
