You want a stevia-sweetened shake that tastes good and does not leave you gassy or bloated afterward. That is the whole job. The picks below cover every angle of that brief — a hydrolyzed grass-fed isolate for lean phases, an unflavored powder you can drop into coffee, a plant-based option, and single-serve stick packs for travel.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You want a stevia-sweetened shake that mixes without clumps and does not upset your stomach. Start with how much protein you need per scoop, then check whether the sweetener is stevia or something else hiding further down the label. Flavor, mixability, and how your stomach handles it decide the right pick — and this rundown of the protein powder with stevia sorts that out for you.
Top Picks


How To Choose The Best Protein Powder With Stevia
Stevia is a plant-based sweetener, and it behaves differently from sugar or sucralose (a common artificial sweetener) in a shake. It can taste clean and creamy in one formula and sharply bitter in another. The base protein, the flavoring, and how much stevia the maker uses drive that difference. So look first at what sits around the sweetener, not the sweetener itself.
Check protein grams per scoop before anything else
Protein per serving is the number that decides whether a tub is worth your money. A 25g scoop delivers more usable protein than a 20g or 21g scoop, so you drink fewer shakes to hit your daily target. If you are dieting, that gap matters even more, because every scoop carries calories and carbs alongside the protein. Look for isolate on the label rather than a blend if you want the leanest profile.
Match the form to how you will actually use it
Flavored tubs suit people who drink shakes straight with water or milk and want a dessert-like taste. Unflavored and unsweetened powders suit anyone who blends into coffee, oatmeal, soups, or baked goods and does not want vanilla fighting the recipe. Single-serve stick packs suit travel, gym bags, and anyone testing flavors before committing to a full tub. Pick the form that fits your routine: a flavored tub for straight shakes, an unflavored one for recipes, stick packs for travel.
Watch the lactose and digestion notes
Whey isolate removes most of the lactose, which is why many dairy-sensitive buyers tolerate it where a concentrate would upset them. Hydrolyzed whey is broken down further, and some formulas add digestive enzymes to help with gas and bloating. If your stomach reacts easily, an isolate or a plant-based blend is usually the safer starting point.

Detailed Reviews
1. SASCHA FITNESS Hydrolyzed Whey Protein Isolate 2 Pounds
Our pick — 4.5+★ from 600+ verified ratings; the strongest balance of quality and price.
Hydrolyzed grass-fed whey with 25g per scoop, sweetened only with stevia.
This is the pick for anyone chasing a lean physique who still wants a shake that tastes like dessert. Each serving carries 25g of protein from a 100% isolate and hydrolyzed grass-fed base, which the maker says your body absorbs very fast — so it suits the window right after training as well as a between-meals hit. That 25g is 19% more protein per scoop than the Orgain plant-based tub at 21g, and it matches the AGN Roots isolate gram for gram while adding flavor.
The stevia story is the reason it sits at the top of this list. There are no artificial sweeteners here — just stevia, described by the brand as a natural sweetener that will not wreck your health. The label also claims zero carbs, sugar and fat and low sodium, which is what makes it workable during a fat-loss phase when every gram gets counted. Digestive enzymes are built in to help with gas and bloating. If dairy has bothered you before, the gluten-free and lactose-free tags are worth noting.
Here is the honest catch: taste divides people. The chocolate-leaning flavors land creamy for some palates and read bitter to others, which is the classic stevia risk. The flavor line is where you should be most careful — buy the smallest size first if you are sensitive to that herbal edge. Quality is what wins people over far and away, and that reputation has real momentum behind it. As buyers report in their own words: “Is like the 5th time I bought it.” Repeat purchases like that tell you the formula delivers for people who stick with it.
What earns its keep
- 25g protein per serving from a hydrolyzed grass-fed isolate
- Sweetened with stevia only, no artificial sweeteners
- Zero carbs, sugar and fat, low in sodium for lean phases
- Digestive enzymes added to help with gas and bloating
- Gluten free and lactose free
What to weigh first
- Flavor splits opinions — some find it creamy, others bitter
- Stevia can carry a herbal edge if you are sensitive to it
Go for it if: you want the highest protein-per-scoop in this lineup with a clean stevia-only label and enzymes built in.
Sample a small tub first if: stevia’s herbal note has tasted bitter to you in other brands.
2. Simply tera’s Organic Whey Protein Powder 12 Oz
Four ingredients, real Bourbon Island vanilla, and an organic stevia finish.
If your protein powder mainly disappears into a smoothie or a bowl of oatmeal, this is the tub to reach for. It delivers 20g of complete protein per serving from grass-fed whey, with only 4 ingredients — including vanilla from the Bourbon Islands and organic stevia. No artificial sweeteners, no added sugar, and no rBGH hormone. That short list is the whole appeal: you can read the label and understand every line of it.
Taste is the thing it does better than almost anything else here, and it does it with real vanilla rather than flavoring. Owners describe the texture as fluffy and note it blends well into smoothies. It also carries all 18 amino acids, including the 9 your body needs for energy, muscle building and cell repair — so it holds up nutritionally alongside the leaner isolates. The trade-off on protein is real, though: 20g per serving falls short of the 25g you get from the SASCHA FITNESS or AGN Roots isolates, so if raw protein density is your priority, look there instead.
What nobody hides on this one is the price of all that simplicity. It is one of the pricier ways to buy whey, and the value question is genuinely mixed — plenty of buyers think it earns its cost, while others feel the hit at checkout. If you use it daily, the spend adds up faster than with a plain isolate. Still, for pure drinking pleasure with a clean stevia-sweetened label, it is hard to argue with.
Where it shines: four ingredients, genuine Bourbon vanilla, and a fluffy texture that folds into smoothies without clumping.
Where it costs you: 20g protein per serving and a premium position on the shelf — a small size makes sense before you commit.
Reach for this if: taste and a short ingredient list matter more to you than squeezing every gram of protein into each scoop.
Pass it by if: you need the densest isolate in this group for a cutting phase.
3. AGN Roots Grass Fed Whey Protein Powder Isolate
An unsweetened isolate you can drop into coffee, soups or baking without a flavor fight.
This one is for the person who wants protein as an ingredient, not a dessert. It is a grass-fed whey isolate that is both unflavored and unsweetened, so there is zero stevia and zero taste to work around. Each 25g-of-protein serving carries 6.5 grams of BCAAs, which the brand calls the highest natural concentration among grass-fed whey competitors. Two scoops per serving means 15 servings per 1lb pouch, and crisp as it is: it dissolves into coffee, smoothies and baked goods without changing the taste of your recipe.
The sourcing credentials are what set it apart from every other tub on this page. It is Certified Animal Welfare Approved by A Greener World, Informed-Sport and Informed-Protein certified, and on the ASPCA’s Shop with Your Heart list. Cold processing keeps the protein undenatured, and it arrives in an air-tight thermally protected pouch rather than a plastic tub. If you have ever had a whey powder that tasted dusty, the moisture control here is the reason this one smells of fresh dairy cream instead. On weight, it is the lightest bag in this lineup at 1 pound — the SASCHA FITNESS tub carries 2.11 pounds — so it is easy to store and ship.
Two things to know before you buy. Plain water tastes mediocre with an unsweetened isolate, so plan on mixing it into something with flavor — coffee and smoothies are the go-to. And the scoop is a tiny half-serving size, meaning you are measuring two of them per shake, which catches new buyers off guard. Cost is the other honest note: it is priced above standard whey, and though many consider it worth it for the certification and clean label, others feel the premium. Owners mention being clear about the math: “2 scoops/serving, 15 servings per 1lb, 25g protein.”
Why it earns a slot
- 25g protein and 6.5g BCAAs per serving
- Completely unflavored and unsweetened — no stevia taste at all
- Informed-Sport, Informed-Protein and Animal Welfare Approved
- Cold processed to keep protein undenatured
- Lightest bag here at 1 pound, easy to store
The trade-offs to expect
- Plain water tastes mediocre; mix it into something flavored
- Half-serving scoop means two scoops per shake
- Priced above standard whey
The right call when: you want maximum flexibility and a clean, unsweetened protein to add to anything from coffee to soups.
Think twice when: you drink your shake plain with water and want flavor built in.
4. Orgain Organic Vegan Protein Powder 2.03 lb
Dairy-free chocolate that does not taste like a compromise.
For anyone avoiding dairy, whey, or simply plant-based nutrition, this is the natural home base. It packs 21g of organic plant protein from peas, brown rice and chia seeds, with all 9 essential amino acids present. The formula has 0g sugar and prebiotic fiber for gut support, and it is certified USDA Organic and plant based. No erythritol in the base formula, no carrageenan, no lactose and no artificial colors or sweeteners. It is also kosher and made without soy ingredients.
The chocolate fudge flavor is the draw here. It gives you a rich cocoa aroma, a creamy consistency, and not much grit after a shake in the blender — so it reads as a real dessert rather than a chore. It blends well with almond milk, and it holds up in overnight oats and baked goods if you want protein in your breakfast. At 21g of protein per scoop, it is 19% less than the 25g isolate picks above, so you will drink it more often to hit the same number.
One warning for anyone sensitive to alternative sweeteners: the sweetener here combines stevia with erythritol, and that aftertaste can stand out. If you have been burned by that flavor before, a simpler stevia-only formula like the Clean Simple Eats stick packs may sit better. For everybody else, this is the most straightforward dairy-free chocolate here, and the 2.03 lb tub covers 20 servings.
The case for it: real cocoa flavor, all 9 essential amino acids, and a clean plant-based label that stays dairy free.
The honest hiccup: the stevia-plus-erythritol combo leaves a faint aftertaste if your palate is tuned to notice it.
Worth grabbing if: you want a dairy-free chocolate shake that blends smooth and tastes indulgent.
Skip the chocolate if: you have a strong aversion to erythritol — try a flavor that leans more on the stevia.
5. Clean Simple Eats Whey Isolate Protein Powder 10 Stick Packs
Ten single-serve packets that let you try five flavors without buying a full tub.
This box is designed for the gym bag, the hotel room, and the desk drawer. Inside are 10 single-serve stick packs across five flavors: Simply Vanilla, Chocolate Brownie Batter, Chocolate Peanut Butter, Coconut Cream and Mint Chocolate Cookie. Each packet holds 20g of cold-processed grass-fed whey isolate plus a digestive enzyme blend, and each is naturally sweetened with stevia and free of artificial flavors, sweeteners and dyes. If you are new to protein powder, this is the sensible way to test flavors before buying a big container.
Taste and quality are what make this pack land so well. The flavors are creamy enough to drink in water or milk and bold enough to boost coffee — the mint chocolate in coffee comes out like a mint chocolate mocha. It blends smoothly with no chalky grit in a shaker, and a hand mixer smooths it out even further. Each packet runs about 100-110 calories with 20g protein and no more than 8g carbs, so it fits a cutting plan without much math. Portability is the whole point of the format, and it is the easiest of the bunch to take through airport security.
The gentlest warning: not every packet flavor is equally strong. The chocolate flavors carry less cocoa punch than the vanilla and snickerdoodle packs, and some drinkers want a bolder chocolate hit. The 10-packet box also runs out fast once you find a favorite. For variety, convenience, and a clean stevia-sweetened label, though, nothing else here matches the format.
The best of it: 20g isolate per packet with five flavors to sample, plus digestive enzymes included for easy digestion.
What to accept: the chocolate flavors are mild, and a 10-pack disappears quickly once you pick a favorite.
Made for you if: you travel, train away from home, or want to sample before committing to a full tub.
Better to pass if: you already know your favorite flavor and want the lowest cost per serving.
6. PERFECT SPORTS Diesel Whey Protein Isolate 360g
French vanilla New Zealand whey that mixes with a spoon in seconds.
This is the pick for the cook. The vanilla is versatile enough to go into coffee, ice cream, muffins and smoothies, and the powder mixes instantly in a shaker or a glass with a spoon thanks to an agglomeration process (a spray-drying step that makes powder dissolve faster). That matters if you hate clumps and do not want to drag out the blender every morning. The whey itself is a New Zealand grass-fed, pasture-raised isolate, cold processed at 4 degrees Celsius to keep the protein and active biofractions (the natural protein parts in milk) intact — and with almost all lactose removed, it suits people who cannot handle standard dairy powders.
The stevia-sweetened formula carries no artificial ingredients, flavors or colors, and the lack of weird aftertaste is what keeps people coming back. It also claims zero carbs and zero fat, which makes it a lean fit for low-carb diets. Customers note loving it in hot coffee and homemade ice cream alike. One note: this is a 360g container, the smallest tub on this page, so it will run out faster than the 2 lb bags if you drink a shake daily. New Zealand whey products also tend to sit at a premium, and this one is no exception.
One fair warning for the label-checkers: this formula carries a California Proposition 65 sticker, which you will notice on the packaging and is worth knowing about before you buy. The flavor and quality are the reasons it is here — clean-tasting vanilla that holds up to heat and other ingredients. If you want a protein that can do dessert duty along with your morning shake, this earns its place.
What makes it worth it
- New Zealand grass-fed isolate, cold processed at 4 degrees Celsius
- Mixes instantly with a spoon, no clumps
- Sweetened with stevia and free from artificial flavors
- Zero carbs and zero fat per serving
- Vanilla flavor works in coffee, ice cream and baking
The fine print
- 360g is the smallest tub here, runs out quickly
- Carries a California Proposition 65 sticker on pack
The right fit for: anyone who blends protein into recipes and drinks it in coffee, and wants a fast-dissolving vanilla isolate.
Look elsewhere if: you want the biggest tub for the money or a package with no Prop 65 sticker.
7. Biochem 100% Whey Protein Isolate Powder 24.6 oz
A near-tasteless isolate for anyone whose stomach reacts to other powders.
This bag is for the buyer who keeps trying whey and keeps getting gas, bloating or an upset stomach. The formula is a 99% lactose free whey isolate, which absorbs quickly without the digestive discomfort, and it delivers all 9 essential amino acids including BCAAs for muscle recovery. It comes from 100% grass-fed cows, certified gluten free, certified vegetarian by AVA, and the first protein brand to reach iGen Non-GMO certification. No artificial colors, flavors or sweeteners, and no rBGH or rBST hormones.
The 20g-per-scoop figure is on the lean side, but the macros are tight: under 1g carbs and 0g fat per serving. That combination is what makes it a fit for low-carb and keto-friendliness alongside clean-eating athletes. It mixes smoothly in water, milk or a plant-based alternative without clumping in a shaker, and the near-neutral taste disappears into fruit, greens and nut butters. If you like a sweet, dessert-style shake, this is not that — it is closer to a blank canvas for whatever you blend it with.
Two quirks to plan around. Stirred with a spoon it can clump, so use a shaker or a blender to get a smooth shake. And the natural flavor is very plain on its own, which is exactly what annoys people who are used to a sweetened chocolate shake. If that sounds like you, pick a flavored option like the Simply tera’s vanilla instead. Everyone sensitive to additives is the audience this one is built for, and the 24.6 oz container holds roughly 30 servings.
Why it earns a spot
- 99% lactose free isolate, easy on sensitive stomachs
- 20g protein, under 1g carbs, 0g fat per scoop
- All 9 essential amino acids including BCAAs
- Certified gluten free, vegetarian and iGen Non-GMO
- No artificial colors, flavors or sweeteners
What may bother you
- Clumps with a spoon, so use a shaker or blender
- Very plain taste on its own, may disappoint sweet-shake fans
Try this if: you have a sensitive stomach and want a near-tasteless protein that vanishes into whatever you blend.
Likely not for you if: you look forward to a sweet, dessert-style shake every morning.
Know the Specs
Protein per serving
This is the grams of protein in one scoop or packet, and it is the first number to compare. A 25g isolate delivers more usable protein than a 20g formula, so you need fewer shakes to hit your target. If you are cutting, every scoop also carries calories and carbs, so a leaner isolate with more protein per serving does more of the work for you.
Stevia vs other sweeteners
Stevia is a plant-based sweetener that adds sweetness without sugar. Formulas that combine stevia with erythritol can carry a cooler aftertaste, while stevia-only recipes vary from creamy to herbal depending on the flavoring and base. If you are sensitive to aftertastes, look for a formula that lists stevia on its own and start with a small size.
Isolate vs concentrate
Whey isolate removes most of the lactose and fat, which is why it suits dairy-sensitive stomachs and low-carb plans. Hydrolyzed whey is broken down further so it absorbs faster, which is what makes it popular after training. A concentrate keeps more lactose and carbs, which is cheaper but harder on some stomachs.
Flavored vs unflavored
A flavored powder suits drinking straight with water or milk and can taste like dessert. An unflavored, unsweetened powder is meant to disappear into coffee, soups, oatmeal or baking without changing the recipe. A flavored tub in your soup will taste strange, and an unflavored one in plain water can fall flat.

The Bottom Line
For most people chasing the best stevia protein powder, the SASCHA FITNESS Hydrolyzed Whey Protein Isolate is the one to beat — 25g of hydrolyzed grass-fed isolate per scoop, sweetened with stevia only, and digestive enzymes included to keep the bloat down. If you want your protein to vanish into coffee and baking without any flavor, reach for the AGN Roots isolate and its Informed-Sport credentials (a third-party test that checks for banned substances). And if dairy is off the table, the Orgain vegan chocolate is the dairy-free answer that still tastes like dessert. Pick the format that fits your routine, because a powder you actually keep drinking is the only one that does its job.
