Optimum Nutrition Gold Standard Whey Nutrition Facts: 24g Protein, 120 Calories, 1g Sugar Per Scoop (2026)

Gold Standard 100% Whey Nutrition Facts (Per Scoop)

These are the official per-scoop numbers as published on Optimum Nutrition's product page (chocolate panel shown; exact values shift a gram or so between the 15-plus flavors).

That is 20g of protein per 100 calories — protein-powder territory that ready-to-drink shakes and bars rarely touch, and the reason a scoop of whey remains the cheapest, leanest way to close a protein gap. The current official ingredient list (chocolate): whey protein isolate, whey protein concentrate, cocoa processed with alkali, natural and artificial flavors, cellulose gum, acesulfame potassium, sucralose, leucine, lactase and digestive enzymes.

What “Whey Isolate First” Actually Means

Whey comes in two main grades. Whey protein concentrate is the standard, cheaper form — roughly 70 to 80% protein with a little more lactose and fat. Whey protein isolate is filtered further to about 90%+ protein with most of the lactose and fat removed. Gold Standard's pitch since the 1990s has been putting isolate first in the blend, with concentrate in a supporting role: you get near-isolate purity at a blend price. That is also why it digests fast and mixes easily with just a spoon and glass. If you want 100% hydrolyzed isolate and nothing else, that is exactly what Dymatize ISO-100 sells — at a higher price per serving.

Sweeteners and Lactose: The Fine Print

• Sweeteners: the sweetness comes from sucralose and acesulfame potassium (Ace-K), two FDA-approved artificial sweeteners — the same pair used by Premier Protein and (as of the current labels) the fairlife shake lines. If you avoid artificial sweeteners, this is not your powder.
• Lactose: Gold Standard is NOT labeled lactose-free, but the formula includes lactase and digestive enzymes, and the isolate-first blend is naturally low in lactose. Many people with mild lactose sensitivity tolerate it; a true dairy allergy rules it out (it is milk-based).
• Gluten-free: yes, per Optimum Nutrition's official claims.

Gold Standard Whey vs Dymatize ISO-100

The two most cross-shopped premium wheys. Both are excellent; they optimize for different things.

The honest summary: for general daily protein and post-workout recovery, the two perform the same job and Gold Standard usually costs less per serving with far more flavor choices (over 15, from Double Rich Chocolate and Vanilla Ice Cream to Fruity Cereal and S'mores). ISO-100 earns its premium only if you specifically want the purest, fastest-digesting isolate or have a touchier stomach. Full flavor-by-flavor detail in our ISO-100 nutrition guide.

Who Gold Standard Whey Fits

• Post-workout recovery: 24g of complete, fast-digesting protein with 5.5g BCAAs is squarely in the range research supports for muscle protein synthesis — see our best post-workout protein snacks guide for how a shake stacks up against food options.
• Budget protein-per-gram: a scoop of whey beats nearly every bar and ready-to-drink shake on cost per gram of protein.
• Calorie-counters: 20g of protein per 100 calories, with the flexibility to mix with water (as labeled) or milk (adds calories and creaminess).
• Not for: anyone avoiding artificial sweeteners, anyone with a milk allergy, or vegans — for plant-based recovery options see our whey vs plant protein comparison.

Frequently Asked Questions

How much protein is in one scoop of Gold Standard Whey?

24g of protein per roughly 30g scoop, at 120 calories, per Optimum Nutrition's official label. That includes 5.5g of naturally occurring branched-chain amino acids (BCAAs), the aminos most associated with muscle recovery.

Is Gold Standard Whey isolate or concentrate?

Both — it is a blend, but whey protein isolate is the first (largest) ingredient, with whey protein concentrate second. That puts its purity closer to an isolate than a typical concentrate powder at a lower price than pure-isolate products.

Does Gold Standard Whey have artificial sweeteners?

Yes — sucralose and acesulfame potassium (Ace-K) are on the current official ingredient list, alongside natural and artificial flavors.

Is Gold Standard Whey gluten-free and lactose-free?

It is gluten-free per Optimum Nutrition. It is not labeled lactose-free, but it is naturally low in lactose and includes added lactase and digestive enzymes, which many lactose-sensitive users tolerate well. It contains milk, so it is unsuitable for a dairy allergy.

How many calories is a scoop with milk instead of water?

The 120-calorie label assumes water. Mixing with a cup of 2% milk adds roughly the milk's own label calories on top — check your milk carton and add the two together; we don't estimate numbers that aren't on a label.

Bottom line: Gold Standard 100% Whey delivers 24g of protein for 120 calories with 1g of sugar and 5.5g of BCAAs, using an isolate-first blend that keeps quality high and price moderate — the sensible default whey, with ISO-100 as the premium pure-isolate upgrade. Know that it is sweetened with sucralose and Ace-K, and compare it against bars, shakes, and whole-food options in the protein snacks directory.
