Dymatize ISO 100 Hydrolyzed Whey Protein 5lb — The Gold Standard of Whey Isolate

Dymatize ISO 100 is one of the most iconic and best-selling whey protein supplements in the world — and has been for over two decades. Alongside Optimum Nutrition Gold Standard 100% Whey, Dymatize ISO 100 is pretty much the definition of an OG whey protein powder — a longtime bodybuilding forum favourite that has evolved over time into a high-quality mainstream supplement trusted by athletes worldwide. Now available in Sri Lanka at PrimeSupps.lk in a 5lb (2.27kg) tub delivering 71 full servings.

Dymatize ISO 100 is an ultrapure, fast-digesting hydrolyzed whey protein isolate with 25g of protein, 5.5g of BCAAs, and 2.7g of leucine per serving — designed for muscle building and made using a multi-step purification process. This is not a blend, not a concentrate — it is 100% whey protein isolate, with a portion hydrolyzed for the fastest possible absorption and digestion.

What Makes Dymatize ISO 100 Different?

Dymatize ISO 100 is produced to the highest quality standards, formulated using a cross-flow microfiltration, multi-step purification process that preserves important muscle-building protein fractions while removing excess carbohydrates, fat, lactose, and cholesterol.

ISO 100 is made with pre-hydrolyzed protein sources to ensure fast digestion and absorption — this means the protein is partially pre-digested before it even enters your body, hitting your bloodstream faster than any standard whey concentrate or even regular whey isolate. The result is quicker amino acid delivery to muscle cells exactly when they need it most — immediately post-workout.

Dymatize ISO 100 is third-party tested by Informed Choice, making it an easy go-to for strength athletes who need to abide by certain governing bodies — and for anyone who wants complete confidence that what’s on the label is what’s in the tub.

The Science Behind Dymatize ISO 100

The hydrolyzed whey isolate formula in Dymatize ISO 100 is backed by extensive independent research. According to Healthline, whey protein isolate is the fastest absorbing and purest form of whey available — and hydrolysis takes this even further by pre-digesting the protein into smaller peptides for near-instant absorption. Examine.com rates whey protein as having strong evidence for increasing lean muscle mass and strength when combined with resistance training. The National Institutes of Health (NIH) confirms that leucine — present at 2.7g per serving in Dymatize ISO 100 — is the primary amino acid responsible for stimulating muscle protein synthesis and is critical for maximising the muscle-building response to exercise.
