Ingredients

  • Erythritol
    Strong A 2023 study linked higher blood erythritol to cardiovascular events and found it increased clotting activity; long-term safety studies are warranted. [1][2]
  • Sucralose
    Strong In a 2022 randomized study, sucralose and saccharin altered the gut microbiome and impaired glucose responses in some people; a 2023 lab study raised questions about its by-product sucralose-6-acetate. [3][4][5][6][7]
  • Cellulose gum (carboxymethylcellulose)
    Strong In a small randomized feeding trial, carboxymethylcellulose modestly increased abdominal discomfort and reduced gut microbiota diversity; in mice it promoted low-grade inflammation. [8][9][10][11]
  • Protein blend (unspecified)
    Info An ingredient typical of ultra-processed foods (NOVA group 4). [12]
  • Milk protein concentrate / isolate
    Info An ingredient typical of ultra-processed foods (NOVA group 4). [12]
  • Whey protein concentrate / isolate
    Info An ingredient typical of ultra-processed foods (NOVA group 4). [12]
  • Soluble corn fiber (resistant dextrin)
    Info An additive class typical of ultra-processed foods (NOVA group 4). [12]
  • Palm kernel oil
    Strong About half saturated fat; WHO recommends keeping saturated fat to 10% of energy or less. [13][14][15]
  • Natural flavors
    Info "Natural flavor" is a legal category (21 CFR 101.22(a)(3)): flavor substances from spices, fruits, vegetables, meat, dairy or fermentation. [16][12]
  • Lecithin
    Info An additive class typical of ultra-processed foods (NOVA group 4). [12]
  • Sunflower oil
    Emerging High in omega-6 linoleic acid. [17][18][19][20]
  • Soy lecithin
    Info An additive class typical of ultra-processed foods (NOVA group 4). [12]
  • Stevia (steviol glycosides)
    Emerging WHO (2023) recommends against using non-sugar sweeteners to control body weight (conditional recommendation); US dietary guidelines advise limiting them. [6][7]
  • Xanthan gum
    Info An ingredient class typical of ultra-processed foods (NOVA group 4). [12]
  • Glycerin
    Info An additive class typical of ultra-processed foods (NOVA group 4). [12]
  • Caseinate
    Info An ingredient typical of ultra-processed foods (NOVA group 4). [12]
