You want a protein powder that fits your budget and agrees with your stomach. But is Dymatize ISO100 worth paying more for, or would Elite Whey do the job for less?
The useful differences are in the formula, ingredients and cost per serving. ISO100 uses whey isolate, while Elite 100% Whey uses a blend that includes whey concentrate. Those differences give you more to compare than the name on the tub.
This Dymatize nutrition review compares the product labels, flavor options and value considerations to help you choose. Start with the product table below, then use the pricing section to compare the exact tubs you are considering.

Dymatize at a glance: which product fits your goal?
Quick answer: Compare ISO100 if you specifically want an isolate-based powder. Compare Elite Whey if you tolerate its ingredients and its current cost per serving is lower. Super Mass Gainer is a separate option for adding substantial calories, not a like-for-like substitute for a normal protein shake.
| Product | Per labeled serving | Main buying consideration |
|---|---|---|
| ISO100 Gourmet Vanilla | 30 g powder: 25 g protein, 110 calories, 2 g carbohydrate and 1 g fat. | Isolate-based formula; compare the price premium and allergens. |
| Elite 100% Whey Rich Chocolate | 36 g powder: 25 g protein, 140 calories, 3 g carbohydrate and 3 g fat. | Concentrate-containing whey blend; compare cost per serving. |
| Super Mass Gainer Gourmet Vanilla | 333 g powder with water: 52 g protein, 1,280 calories and 245 g carbohydrate. | A very large serving designed to add calories; check whether you need that much. |
These are the manufacturers’ US flavor-specific figures, not a guarantee that every regional formula or older tub is identical. Milk, fruit or other additions change the finished shake’s nutrition. On a phone, swipe the table sideways if needed.
What you should know about the Dymatize brand
Dymatize is part of BellRing Brands. Older descriptions that simply call it a Post Holdings brand miss the later corporate separation. Ownership is useful background, but it does not establish how well a particular powder fits your needs.
The range includes protein powders, mass gainers, ready-to-drink shakes and workout supplements. This review focuses on the three powders linked below so the buying comparison stays practical. A ready-to-drink product serves a different convenience need, and creatine should be evaluated separately from protein.
For that separate decision, see our creatine supplement comparison. There is no need to buy an entire product range just because one item suits you.
ISO100: when the isolate formula is worth considering
The Gourmet Vanilla manufacturer label lists hydrolyzed whey protein isolate and whey protein isolate. Hydrolysis means some protein has been broken into smaller peptides. That description alone is not evidence of better long-term muscle gains than another protein source.
Dymatize describes filtration that removes excess lactose, carbohydrate and fat. However, low lactose does not mean dairy-free or guarantee comfortable digestion. The referenced vanilla label contains milk and soy, plus sucralose and steviol glycosides. Do not use it if those allergens make it unsuitable for you.
Consider ISO100 when its particular formula solves a problem you actually have. If another suitable powder already fits your meals and budget, the isolate label alone is not a reason to replace it. The linked Amazon option is Gourmet Vanilla, 3 lb; verify the selection on the product page.
Elite 100% Whey: compare the everyday cost
The Rich Chocolate label uses whey concentrate, whey isolate and hydrolyzed whey concentrate. It also lists cocoa, sweeteners and a gum blend. It contains milk and soy.
The two regular protein powders in the table provide the same labeled protein amount, while their calories and ingredients differ. Decide whether those differences matter for your normal eating pattern before paying more. A modest difference in calories is not, by itself, a complete reason to choose one powder.
Elite Whey may be the better-value purchase if its current cost per serving is lower and it suits your dietary needs. That is a price comparison to make at checkout, not a promise that Elite is always cheaper. The linked Amazon option is Rich Chocolate, 5 lb.
Super Mass Gainer: a calorie decision first
The Gourmet Vanilla manufacturer label defines a full serving as 333 g of powder mixed with water. This is much larger than a serving of either whey powder above. Its protein figure should not be compared without also considering that serving size and its substantial carbohydrate content.
Ask whether your existing meals leave a meaningful calorie gap. A large gainer serving can overshoot what you intended to add. If using a smaller portion, measure it and calculate the corresponding nutrition rather than assuming every scoop represents the full labeled serving.
The product contains milk and soy. It can be convenient when adding food is difficult, but it does not guarantee that weight gained will be muscle. The linked Amazon option is Gourmet Vanilla, 6 lb. For another label comparison, read our Pro Gainer review.
Taste, mixing and digestion: what this review can tell you
We have not taste-tested these powders, so there is no claimed favorite flavor, measured mixing result or personal digestion verdict here. A label comparison can identify ingredients; it cannot tell you whether you will enjoy a large tub every morning.
Before buying, consider how you plan to prepare it. Water, milk and a blended smoothie create different drinks. Follow the container’s mixing directions, and include any added ingredients when tracking your intake. If you are uncertain about a flavor, a smaller available pack limits the amount you commit to.
Lactose intolerance and milk allergy are different issues. An isolate can still contain milk proteins, and individual digestive responses vary. If a powder repeatedly causes symptoms, do not assume that a premium label means you should keep using it. Check ingredients and discuss persistent symptoms with a qualified clinician.
Does Dymatize help you meet your protein needs?
The useful role of a protein powder is to fill a gap in your food intake. The ISSN position stand on protein and exercise describes about 1.4–2.0 g of protein per kilogram of body weight per day as sufficient for most healthy exercising individuals. At 75 kg, that is about 105–150 g daily from food and supplements combined. Individual needs can differ.
You do not need to obtain that entire amount from shakes. Review your usual meals first, then decide whether a convenient serving of powder adds anything useful. Our protein portions and easy meal ideas can help you plan around ordinary foods.
Before or after training can both be practical times to eat protein. The ISSN review emphasizes that timing depends partly on tolerance and the surrounding meals. Do not let finding a precise shake time distract from eating consistently and following a manageable training plan.
If you need a simple schedule to pair with those meals, see the three-day gym framework. Buying a particular powder does not replace progressive training or recovery.
Quality testing: check the product, not only the brand
The Informed Choice directory lists ISO100 Hydrolyzed Protein Powder (USA), Super Mass Gainer (USA) and Elite 100% Whey Protein. Check the current product listing and relevant market before relying on a certification claim.
Banned-substance testing and muscle-building effectiveness answer different questions. A certification listing does not establish that one powder produces greater gains, nor does it make every product carrying the same brand interchangeable. Competitive athletes should also follow their sport’s supplement guidance.
Pricing and value: compare cost per serving
The price of a tub is only the starting point. Compare the same currency, include delivery charges that apply to you, and check the serving count for the exact flavor and size. The buttons in this article lead to Amazon.com; Canadian readers should check shipping eligibility, currency conversion and any import charges shown at checkout.
Cost per serving = total price ÷ labeled servings. For protein powders with different protein amounts, also compare the cost for an equivalent amount of protein. A gainer’s extra carbohydrate changes its purpose, so do not rank it as an ordinary whey powder on price alone.
For example, a hypothetical $60 tub with 30 servings costs $2 per serving. A hypothetical $75 tub with 50 servings costs $1.50 per serving. These are arithmetic examples, not current Dymatize prices or advertised offers.
| Your situation | Option to compare | What to check |
|---|---|---|
| You want an isolate-based powder | ISO100 | Ingredients, allergens and the extra cost per serving. |
| A concentrate-containing blend suits you | Elite 100% Whey | Whether its current serving cost is lower. |
| You need substantial additional calories | Super Mass Gainer | Serving size, total calories and fit with your meals. |
| You compete in tested sport | An appropriately certified product | Exact product and market in the current certification directory. |
| Food already covers your protein needs | No powder purchase required | Whether a shake adds useful convenience. |
Buying, returns and authenticity
Check who sells and ships the selected listing. A familiar marketplace name does not mean every offer comes from the same seller. Review the current return policy before buying, especially for opened food or supplement products. This review does not promise a universal 30-day return window.
On arrival, inspect the seal, expiration date and label. Keep the container and lot details if you need to contact the seller or manufacturer about a product issue. Dymatize provides official product support and retailer information.
Pros and limitations
- Useful comparisons: the flavor-specific labels make it possible to compare protein, calories and ingredients directly.
- Different options: isolate, a whey blend and a calorie-dense gainer address different shopping needs.
- Testing information: relevant products can be checked against a public certification directory.
- Limitations: price, taste preferences, allergens and digestion can still make a product unsuitable. A premium description is not proof of better results.
Quick answers about Dymatize protein
Is ISO100 lactose-free?
Do not assume every ISO100 flavor or market is lactose-free. Dymatize describes filtration that removes excess lactose, but the referenced Gourmet Vanilla label still declares milk. Read the exact container; low lactose is not the same as being suitable for a milk allergy.
Is ISO100 better than Elite Whey?
It depends on what you need from the formula. Compare the ingredients and serving cost. The label comparison above does not establish that ISO100 builds more muscle than Elite Whey.
Should I take a shake before or after training?
Choose a time that fits your meals and is comfortable for you. Both can be practical; there is no reason to build your entire routine around a single brand’s shake.
Is Super Mass Gainer a replacement for ISO100?
They serve different purposes. Super Mass Gainer adds a large amount of calories and carbohydrate per full serving. If you simply want to fill a protein gap, compare the regular protein powders and food options first.
Can Dymatize protein cause fat loss?
A protein powder is not a fat-loss treatment. The referenced ISO100 and Elite labels say to use them as food supplements, not for weight reduction. Consider the complete diet rather than expecting a particular powder to change body composition on its own.
Final verdict: buy for a specific need
ISO100 deserves a comparison when you want its isolate-based formula. Elite Whey deserves a comparison when a concentrate-containing blend suits you and offers better value at the current price. Super Mass Gainer belongs in the discussion only when its extra calories fit your plan.
Choose the exact flavor and size you are comfortable buying, check the full label, and compare the delivered cost per serving. If your existing meals already do the job, there is no requirement to add a powder.
