Dymatize ISO 100 Hydrolyzed Whey Protein Isolate
ISO 100 delivers 25g of protein per serving from hydrolyzed whey protein isolate and whey protein isolate, with about 1g of sugar or less and 110–120 calories depending on flavour — making it the go-to protein for athletes tracking macros strictly or pushing through a cut. Unlike blended proteins that include concentrate, ISO 100 is filtered to remove excess lactose, carbs, and fat, leaving a fast-absorbing protein with 5.5g of BCAAs per serving, according to Dymatize. Bulldog Nutrition is an authorized Canadian and US retailer of Dymatize — every tub is 100% authentic and ships fast across Canada and the US.

Why Dymatize ISO 100?
- 25g protein per serving — from hydrolyzed whey protein isolate and whey protein isolate; Dymatize describes the hydrolyzed whey as fast-absorbing
- About 1g of sugar or less and 0.5–1g of fat per serving, depending on label version
- Filtered to remove excess lactose, carbs, fat and sugar, according to Dymatize — 2g carbs per serving on the Gourmet Chocolate label
- 5.5g naturally occurring BCAAs per serving, including 2.6g leucine (per Dymatize)
- Several flavours — Gourmet Chocolate, Gourmet Vanilla, Fudge Brownie, Cinnamon Churro, and more
Who Is This For?
ISO 100 is built for serious athletes who track their macros precisely and can't afford carb or fat creep from their protein source. It suits a cut or body recomposition phase — most of its calories come from protein, with very little sugar or fat. Dymatize describes ISO 100 as easily digestible and filtered to remove excess lactose, but it is still made from milk. If you want a hydrolyzed whey isolate in a 5lb tub, this is it.
Who Is This NOT For?
- ✗ Hard-bulk athletes who need calorie-dense shakes — at ≤120 cal/serving, consider a mass gainer instead
- ✗ Anyone sensitive to artificial sweeteners — ISO 100 contains sucralose and/or stevia depending on flavour
- ✗ Vegans or vegetarians — this is a dairy-derived whey protein
- ✗ Budget-focused buyers — an isolate generally costs more than a blended whey
- ✗ Under 18 — not intended for use by minors
What's In It?
ISO 100 uses two protein ingredients: hydrolyzed whey protein isolate and whey protein isolate. Hydrolyzed means part of the protein has been broken down with enzymes into smaller peptides — Dymatize describes it as fast-absorbing and easily digestible. Each serving provides 25g of protein, 5.5g of BCAAs (including 2.6g leucine, per Dymatize), 110–120 calories depending on flavour, about 1g of sugar or less and 0.5–1g of fat depending on label version. Sweetened with sucralose and stevia (Gourmet Chocolate label); see the label on your container for your flavour's full ingredient list.
⚠️ Contains milk and soy. Chocolate Peanut Butter also contains peanut — check the label of any peanut-flavoured tub, including Peanut Butter, before use. Always read the full label before use. These statements have not been evaluated by Health Canada or the FDA for disease treatment or prevention.
