ISO100 combines high protein density, very low sugar and a disclosed 2,6 g leucine dose. Current Informed Choice entries strengthen the evidence trail. The premium price is real, and the format is most defensible for buyers who specifically value a low-lactose isolate and sport certification.

Formula and ingredients
Dymatize reports 25 g protein, no more than 120 calories, 5,5 g BCAAs and 2,6 g leucine per serving. Protein comes from whey isolate, including hydrolysed isolate. “Fast absorbing” is plausible, but evidence does not establish a superior long-term muscle outcome over an adequate dose of another complete whey.
Laboratory and certification trail
Informed Choice lists ISO100 separately for North America and Europe. The U.S. entry showed Salted Caramel batch M2605952 tested on 19 October 2026; the European directory also showed current 2026-tested lots. These entries address banned substances, not a full public contaminant and nutrient panel.
Company accountability
The Dymatize site identifies BellRing Brands in its corporate links. The score is based on the product label and external Informed Choice records, not corporate scale or athlete endorsements.

Named Best Protein Powder by Women’s Health. This reflects editorial testing and taste/use experience; it does not change the scientific score.
See the issuing source ↗Where this fits
A strong fit for buyers who want an isolate with visible batch testing. Buyers who tolerate whey concentrate or blended whey can often meet the same nutrition objective for less.
Limits and update trigger
Public certification is region- and batch-specific. ShreddedAF did not purchase, taste or independently assay the product.

Source rule: Manufacturer pages establish the current label and claims. Independent certifier directories establish only the specific certification, region and batches they list. Editorial awards never alter the score.
