Great taste and mixes well
Really solid protein powder! It mixes very easily with no clumps and has a smooth texture. The taste is great compared to other brands, not too heavy or overly sweet. Perfect for post-workout and easy on the stomach. Definitely a high-quality option and worth it!

Tasty though clumpy
I’ve been a fan of Dymatize ISO100 Whey Protein Powder Isolate in Gourmet Vanilla (the 20-serving tub, around 1.4-1.6 lbs depending on the pack) for several months now, especially as a reliable, clean post-workout option that doesn’t disappoint on taste or performance. If you’re looking for a straightforward vanilla that mixes into something enjoyable without tasting like “protein powder,” this one’s a winner.The Gourmet Vanilla flavor is one of the best vanilla isolates out there—creamy, smooth, and reminiscent of a light vanilla milkshake or ice cream base, with just the right sweetness (not overly artificial or cloying like some competitors). It has that classic vanilla bean note without a strong chemical aftertaste; many reviewers call it dessert-like, and it blends beautifully into smoothies, oatmeal, or even coffee for a protein boost. I usually mix one scoop with unsweetened almond milk or water in a shaker—dissolves instantly with no clumps, froths up nicely for a creamy texture, and leaves zero grittiness.Key highlights:• 25g protein per scoop from 100% hydrolyzed whey isolate—super fast-absorbing and gentle on the stomach (no bloating or digestive issues for me, even on an empty stomach).• 5.5g BCAAs (including 2.6g leucine) for solid muscle recovery and growth support.• Ultra-clean macros: under 120 calories, 1g fat, 1g sugar, 2g carbs—gluten-free, low-lactose, perfect for cutting phases or anyone watching carbs/sugar.• Mixability is flawless; it’s one of the smoothest proteins I’ve used.I’ve gone through a couple of these tubs quickly because the flavor makes shakes something I actually look forward to—great for breakfast on busy mornings, post-gym recovery, or curbing sweet cravings without junk. It’s Informed-Choice tested for banned substances, adding peace of mind for consistent quality.Only small drawbacks: It’s on the sweeter side (some find it too sweet straight with water; I prefer it diluted or blended), and the premium price (~$30-40 for 20 servings) reflects the hydrolyzed isolate quality—worth it for the purity and taste, but not the cheapest basic whey. If you want less sweetness, the unflavored or other variants might suit better, but Gourmet Vanilla is a top pick for flavored fans.Highly recommend this as a go-to vanilla protein—clean, delicious, and effective. 5 stars—easily one of my favorites for daily use

Clean, Fast-Digesting Protein That Actually Mixes Well
Not all whey protein is created equal. Some are too heavy, too sweet, or hard on the stomach.

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 textureOverall: a high-quality whey isolate that delivers performance and consistency without unnecessary fluff.

Great source of protein
Absolutely the best on the market! Tastes great plain or with fruit. Blends well. I’ve read others having issues with the smell, but I have been using this for over a year and never had that issue.ISO100 Isolate, has the least cholesterol and calories, while maintaining the highest protein. I’m not a body builder, so I rely on this product for my main source of protein in my mid-60’s, without worrying about excessive weight gain.My only negative comment…price seems to swing faster than the stock market!

Great taste and easy to mix
I really liked this protein. It mixes super easily with no clumps, and the vanilla flavor tastes good without being too sweet. I use it after workouts and sometimes for breakfast, and it feels light on my stomach. It also has a solid amount of protein per serving, so it feels like a complete option. I would buy it again

Delicious, and you get the exact amount of powder they claim
Think I found my permanent protein powder solution with the “Gourmet Vanilla” flavor of this. Just delicious. Doesn’t lead to upset stomach like other popular whey powders.Some one-star reviewers complaining about “shrinkflation”– ignore it. Yes, the container shows up “half empty”, but that is sort of industry marketing standards. They don’t short you any powder.I carefully measured and weighed the powder in two brand new containers. Almost exactly 22 oz in each. (advertised as 21.5 oz, so seems you actually get a pinch more)Couldn’t recommend this powder enough.

Tastes great, easy to mix
I’ve tried several protein powders and didn’t like the taste of them. This one was different. Tastes pretty good. Better than most. Seems easy to mix into milk.
