While we’ve uncovered plenty of the best protein powders over the years, we understand that not every supp is the perfect puzzle piece for everyone’s fitness picture. For example, athletes looking for a quick-digesting protein that won’t leave their gut tossing and turning mid-workout may prefer a hydrolyzed whey protein option such as Dymatize Iso 100. In addition to its gut-friendly makeup, this popular protein supplement features an approachable price per serving, as well as delectable flavors that can leave you satiated and satisfied.

Dymatize Iso 100 Whey Protein is just one of the over 100 protein powders we’ve tested over the years, but the formulation continues to hold merit as a top pick for budget-minded athletes, as well as those more sensitive to potential GI side effects associated with other types of protein. In this Dymatize Iso 100 protein review, we’ll look closely at the formulation and specs of this supplement, as well as provide insight gathered from our personal experience with this taste-filled powder.

Dymatize Iso 100

A protein powder comprised mostly of hydrolyzed whey, which may help you recover more quickly than other forms of whey.

Watch as _BarBend_’s Nick English outlines this Dymatize protein powder’s benefits, drawbacks, taste, pricing, ingredients list, and more.

Main Takeaways

• This is a protein-forward formulation, meaning a single serving shouldn’t make too much of an impact on your daily carbohydrate and fat counts.
• Dymatize Iso 100 is sweetened with sucralose and stevia — the latter of which can be known to cause GI distress in some athletes.
• Container sizing can reach as high as 76 servings, although you may be limited as to which flavors are available at this quantity.

Dymatize Iso 100 Specs

Dymatize Iso 100 is available in containers with anywhere from 20 to 76 servings, which equates to costs per dosage starting around $1.25. This is especially noteworthy given that hydrolyzed whey protein is oftentimes the most expensive option when it comes to the different types of protein. Speaking of hydrolyzed whey, studies report that it’s one of the better-digesting protein options available, making it a great solution for those with more sensitive stomachs. (1)

Iso 100 is available in 13 different flavors, which include unique collaborations with Post Cereal and Dunkin’. “I had the Dunkin’ Glazed Donut option, and it honestly reminded me of my go-to order — a maple bar,” notes our product tester. “It was sweet, but not overbearing. Honestly, I felt it was a nice reminder of my past where Dunkin’ was a morning staple of mine.”

Dymatize Iso 100 nutrition facts

The great taste also marries well to this supplement’s impressive mixability. According to our tester, this powder blended easily in a shaker bottle without much effort. However, we do recommend opting for a more savory liquid as a base — the flavors can begin to fade if you’re solely mixing this best whey protein powder with water.

To get into the metrics, you can expect 25 grams of protein in each serving, regardless of your flavor choice. “I like that you get 5.5 grams of BCAAs in the 25 grams of protein per serving,” states certified dietitian nutritionist Chelsea Rae Bourgeois, our expert reviewer. “And since Dymatize removes all the excess carbs , fat, lactose , sugar, and cholesterol , your body can focus on absorbing the protein efficiently.”

The 5.5 grams of BCAAs are also noteworthy with this supplement, particularly the 2.6 grams of leucine. Studies suggest that leucine can be a major player when it comes to sustained muscle growth. (2) While the 110 to 120 calories per serving may lend themselves to more of a weight loss protocol than a muscle-building regimen, we do appreciate the added amino acids to cover all bases (at least somewhat).

Lastly, Dymatize Iso 100 is third-party tested by Informed Choice, making it an easy go-to for strength athletes needing to abide by certain governing bodies. We always recommend seeking out supplements with third-party testing, as it can be a quick way to ensure that the listed formulation and dosages are accurate.

Who Should Use / Who Shouldn’t Use Dymatize Iso 100

While Iso 100 may be one of our favorite whey protein powders, especially under the hydrolysed whey umbrella, we understand that its formulation may not meet the needs of every palate out there. Below are some recommendations we have for who should and shouldn’t consider adding this impressive protein supplement to their regular regimen.

Recommended for:

• Athletes wanting a protein source with minimal impact to their daily carbs and fat counts
• Individuals susceptible to GI distress with other protein powder types
• Those looking to keep supplement costs low — servings begin at $1.25 per dose

Not Recommended for:

• Those looking to support a bulking phase with higher calories per serving
• Athletes wanting an abundance of fruit-based flavors
• Clean eaters looking to avoid artificial sweeteners

Our Experience Using Dymatize Iso 100

As we’ve done with over 100 different protein powders varieties, we mixed Dymatize Iso 100 in our favorite shaker bottle and, after sipping it for multiple weeks, took notes on key categories including solubility, side effects, cost per serving, and (of course) taste. We then scored these findings on a scale of 1 (lowest) to 5 (highest). Here are some of our takeaways.

Ingredients and Formulation

When it comes to the makeup of Dymatize Iso 100, we were fairly impressed with its lean, low-carb formulation. Regardless of flavor, you can expect to receive 25 grams of protein, up to 3 grams of carbohydrates, and no more than 1 gram of fat per single-scoop serving. Additionally, we feel the max 120 calories per dose can be excellent for those seeking one of the best protein powders for weight loss.

Another perk associated with this Dymatize offering is its use of hydrolyzed whey protein. According to our tester, this protein type digested easily throughout the day, even post-workout, with no apparent side effects or uncomfortable situations.

We did rate the formulation at 4 out of 5, though, given this powder’s inclusion of stevia and artificial additives. “It’s sweetened with sucralose and stevia and contains artificial flavors , which may leave a poor aftertaste for some,” notes Chelsea Rae Bourgeois, our expert reviewer. “Plus, it doesn’t feature a strong vitamin and mineral profile, so you’ll need to make sure you’re getting those nutrients from your whole foods.”

Taste

In testing, we were happy with the sampled flavors of this protein powder, and particularly enjoyed the Dunkin’-sponsored offerings that had us feeling like we were right in line at the coffee shop. However, we scored the taste at 3.5 out of 5 given the mixed results we saw when blending this supplement with water alone. “While I thought the thin consistency was a perk for drinkability, I will admit that it did leave something to be desired in the flavor department,” says our tester.

As a result, we recommend mixing Dymatize Iso 100 with a richer beverage, such as dairy-based or cow-based milk. You can also try to avoid thin consistencies by adding it to your favorite smoothies, although this may be more of a chore given the fact that a majority of the flavors are chocolate derivatives.

Solubility

Okay, so we just stated that the consistency can be thin when mixing Dymatize Iso 100 with water, but that doesn’t mean the powder won’t dissolve efficiently. We scored the solubility at 4.5 out of 5 and found no clumps or apparent residue in our shakers. This can be a definite perk for athletes needing a quick hit of the vital macronutrient before a workout, as there’s no need to violently stir or shake this supplement to achieve a drinkable blend.

Independent Lab Results

This impressive protein powder is third-party approved by Informed Choice, which ensures that it’s free of banned substances and that the listed serving sizes are accurate across the entire makeup. However, we’ve also employed an independent, third-party accredited lab of our own to test this protein powder’s purity and label accuracy.

This Gourmet Vanilla variety of Dymatize ISO 100 Hydrolyzed Whey earned an overall A grade for purity and label transparency from our independent accredited lab.

Our findings resulted in Dymatize Iso 100 earning an A grade overall, scoring in the top 10% of more than 150 protein products tested for the presence of metals, pesticides, phthalates, and bisphenols.

Price Per Serving

The fact that Dymatize Iso 100 starts at $1.25 per serving is quite an achievement. Hydrolyzed whey, after all, is typically the most expensive protein type given the extra manufacturing steps that expose it to heat, enzymes, or acids to “pre-digest” the protein. Plus, as one of the best protein powders on Amazon, you can extend those savings even further by keeping tabs on regular sales windows or large shopping events, such as Prime Day or Black Friday. As such, we rated the price per serving at 4.5 out of 5.

What to Consider Before Buying Dymatize Iso 100

Buying a protein powder may seem like an easy endeavor — find the formulation that matches your palate and fits within your budget, right? Well, whether ordering a tub of Dymatize Iso 100 or some other option, there are multiple factors worth pondering over before confirming your cart at checkout.

• Protein Per Serving: “Each person’s protein needs are unique to them and will vary,” notes Samina Qureshi, a registered dietitian. “You can calculate your protein needs by multiplying your weight in kilograms by 0.8 to 1. (3) This will give you a general idea of how much protein to consume, but other considerations will impact your daily protein needs, including age, gender, activity levels, infections, or chronic health conditions like kidney disease.”
• Calories Per Serving: In addition to protein counts, you should also ensure that your powder’s calories are aligned with your fitness goals. For example, the best protein powders for weight gain often feature a more dense formulation, while those better suited for weight loss can come with lower calorie counts that mesh easily with your whole-food nutritional plan.
• Available Flavors: There’s no sense in choosing a protein powder that tastes bad. Look through the available tastes and try to find one that tickles your palate. It can also be useful to opt for an offering with multiple appealing flavors, as this can help you stick to a similar formulation over multiple months while preventing flavor fatigue.
• Third-Party Testing: Having a protein powder with third-party certification can help ensure that its formulation is accurate and the ingredients don’t include any banned substances. This can be especially important for strength athletes that need to build their supplement regimen in accordance with specific regulations set by their sport’s respective governing body.
• Price Per Serving: Most whey protein powders will cost between 1and1 and 1and3 per serving, based on our research, but always be sure to take a look at your finances before purchasing a tub of your own. You can also browse for subscription-based discounts that offer the powders at lower rates for regularly-scheduled deliveries.

Dymatize Iso 100 Vs. Competitors

Dymatize Iso 100 does stand out thanks to its utilization of hydrolyzed whey protein, but it is by no means the only high-quality protein powder out there. Below, we’ve outlined some comparable protein powders to Dymatize Iso 100 — 100% Grass-Fed Whey Protein Isolate from Transparent Labs and the iconic Gold Standard Whey Protein from Optimum Nutrition.

Transparent Labs 100% Grass-Fed Whey Protein Isolate has long been one of our favorite protein powders thanks to its clean, gluten-free, non-GMO makeup free of artificial flavors, artificial sweeteners, and artificial colorings. However, it’s not without negatives, especially when compared to Dymatize Iso 100. For one, the price per serving is more expensive. Also, there is just one lone container size to choose from, eliminating the possibility of buying your supplements in bulk for a cheaper cost.

Another competitor to Iso 100 is Optimum Nutrition Gold Standard Whey Protein. This iconic supplement comes in an abundance of flavors and is one of the cheaper proteins available, with prices starting at $0.98 per serving. However, the protein per serving is lower than that of Dymatize, and the protein source includes whey concentrate, which can potentially lead to stomach issues for athletes more sensitive to lactose.

Places to Buy Dymatize Iso 100

In addition to the brand’s dedicated site, you can also purchase Dymatize Iso 100 from popular third-party retailers including GNC, The Vitamin Shoppe, Amazon, Target, Walmart, and more.

Customer Experience and Brand Reputation

Dymatize has been a popular supplements brand for over 25 years, crafting tasty, clean formulations across multiple categories. The brand has also bolstered its lineup of some of the best casein proteins, whey protein isolates, and mass gainers through unique collaborations with popular food companies, such as Post Cereal and Dunkin’.

Our Final Verdict on Dymatize Iso 100

In our opinion, Dymatize Iso 100 is an excellent option for athletes wanting a fast-digesting supplement that’s easy to mix and delivers on taste (provided you mix it with a liquid other than water). The lean makeup and low starting price also make it one of the best clean protein powders we’ve tested, although those looking for a calorie-dense makeup to support a bulking phase may prefer a heavier formulation above the max 120 calories featured in this offering.

When choosing a protein powder, you should always think about your dietary goals and how you want your supplements to fit within your regimen. A mix of palate-pleasing flavors and stamps of approval from accredited third parties are also nice touches. Use this information and stock up on your next favorite protein-rich treat.

That said, Dymatize Iso 100 packs 25 grams of protein per serving without excessive carbs or fat. This formulation could be sufficient for muscle growth provided you’re meeting your dietary goals with other protein-rich foods throughout the day and putting the work in with your training.

Is Dymatize Iso 100 good for weight loss?

A high-quality protein powder for weight loss can vary from person to person. However, Dymatize Iso 100’s low calorie counts between 110 and 120 per serving do lend themselves to maintaining a caloric deficit more easily than denser formulations on the market.

How much does Dymatize Iso 100 cost?

The price you pay for Dymatize Iso 100 can depend on your chosen container size, which ranges from 20 to 76 servings per tub. Prices start at $1.25 per single-serving scoop and will go up when ordering smaller containers, so it can be beneficial to purchase this protein powder in larger quantities.
