ISO100

Not all whey protein is created equal. Some are too heavy, too sweet, or hard on the stomach. The Dymatize ISO100 Whey Protein Powder (Vanilla, 5 lb) stands out because it delivers exactly what performance-focused users want: fast digestion, clean taste, and reliable mixability. This isn’t a “dessert shake” protein — it’s a functional, high-quality isolate that fits easily into a serious training routine. ⸻ ✅ Pros 1) Hydrolyzed whey isolate = fast absorption ISO100 is made from hydrolyzed 100% whey isolate, which means: • very low fat • very low carbs • easy digestion • quick post-workout absorption It feels light and efficient, especially after hard training sessions. 2) 25g of protein per serving A clean, solid protein dose that supports recovery without unnecessary extras. Perfect for post-workout shakes or as a simple protein boost during the day. 3) Mixes extremely well This is one of its biggest strengths. It dissolves quickly in water or milk with: • minimal clumping • smooth texture • no gritty aftertaste Even with just a shaker bottle, it blends easily. 4) Vanilla flavor is balanced The Vanilla flavor is: • not overly sweet • not artificial-tasting • easy to drink consistently It also works well mixed with oats, smoothies, or yogurt. 5) Large 5 lb size offers strong value If you use protein regularly, the 5 lb tub makes financial sense and reduces how often you need to reorder. ⸻ ⚠️ Cons 1) Premium price compared to basic whey You’re paying for isolate and hydrolyzed quality. It’s not the cheapest option on the shelf — but the digestibility and texture justify it for many users. 2) Not a mass gainer This is lean protein. If you’re looking for high-calorie shakes, you’ll need to add carbs or fats separately. 3) Artificial sweetener taste (slight) While well-balanced, there is still a mild sweetener presence if you’re very sensitive to that. ⸻ Wrap Up: Is Dymatize ISO100 Worth It? If you want a clean, fast-digesting whey isolate that mixes smoothly and tastes good enough to drink daily, the Dymatize ISO100 Vanilla is an excellent choice. It’s especially well-suited for: • post-workout recovery • athletes managing macros • anyone who values digestibility and texture Overall: a high-quality whey isolate that delivers performance and consistency without unnecessary fluff.

I’ve been really happy with this protein powder. The Gourmet Vanilla flavor tastes great and doesn’t have any funky aftertaste. It goes down easy and blends really well, especially when I mix it into Greek yogurt. It mixes smoothly without clumps and adds a nice flavor without being overpowering. Overall, it’s a solid protein powder that tastes good and is easy to use. I’d definitely recommend it.

This is my go-to protein powder. It tastes delicious and does not affect my stomach like some other protein powders. I have only had vanilla but am going to explore some other flavors.

I use this every day. It is such a delight. I mix it into my coffee and it tastes like a $10 drink (but not too sweet). I cannot emphasize enough how EASY this blends in. I've tried many many protein powders over the years, this is by far the most blendable. I stir it with a fork for (maybe) 10 seconds, and it's almost completely dissolved. Often the only lumps are on the fork, and since it is so smooth and tasty, I just pop that in my mouth. The only caveat to that is that it will get very weird and clumpy in super-hot beverages. I usually blend it into a few ounces of water, pour cold coffee over it, and then give that a quick stir. I've also had it on it's own, or shot some water flavor enhancer in it (which gives it a Dreamsicle-like flavor)

tastes much better with milk or a milk substitute, with water it tastes kind of off. mixes well, but not as easily as they claim

I used to get the naturally flavored version (stevia etc) but they stopped making it, so I use this one now. It has the best texture and has been the easiest to digest powder I've used, no gas or bloating whatsoever. The stats are good, and anytime I see articles about protein powders faking stats or being contaminated this brand always comes out unscathed. They have lots of flavors but I just stick with vanilla. There are cheaper options out there but think this is a case of getting what you pay for

One of my favorite whey protein powders. Protein content is great, high quality, doesn’t upset my stomach, and the flavor is great. Also, it’s not too sweet and can be mixed in with a variety of drinks and food.

Great portion. Actually tastes good.

Great product

Good taste

Easy for my stomach. Dissolves very well. Best protein shake I’ve ever had and I prefer the vanilla flavour. I get to mix it with my yogurt and overnight oats. I also take it immediately after a good workout to prevent fatigue and soreness.
