This guide compares nine top all-in-one shakes across protein, digestive support, and superfoods to help you pick the right fit.

You want one scoop to cover more than just protein—maybe replace a meal, speed up recovery, or settle your stomach. The right all in one protein supplement does exactly that, packing meal-level nutrition into a single shake.
Our Picks at a Glance
How To Choose The Best All In One Protein Supplement
An all-in-one shake is a balancing act between protein, digestive support, and micronutrients. You want enough protein to build or maintain muscle, plus probiotics and enzymes so that protein actually digests comfortably instead of leaving you bloated.
Look past the protein headline
Most buyers fixate on the protein number, but the true value of an all-in-one lives in what else is in the scoop. Probiotics, prebiotics, and digestive enzymes improve digestion and nutrient absorption, reducing stomach discomfort. Added fiber extends fullness, turning a shake into a satisfying meal replacement.
Match the protein source to your body
Whey blends digest fast and work well post-workout, while plant proteins like pea or soy are gentler for sensitive stomachs and fit vegan diets. Some formulas mix egg white, collagen, and plant proteins to create a broader amino acid profile. Choose a protein source that suits your digestion, not just the premium label.

In‑Depth Reviews
1. BODi Shakeology Whey Protein Powder Blend — Chocolate
Our pick — over 4.5★ from 550+ verified ratings; the strongest balance of quality and price.
The meal-replacement heavy hitter that balances 17g of protein with serious gut support.
What sets this apart is the complete formula, not just the protein. Each serving gives you 17g of protein from a whey and pea blend (a mix of dairy and plant sources), plus flax and quinoa for extra nutrients. It also adds 6g of fiber, probiotics (good bacteria), prebiotics (food for those bacteria), and digestive enzymes—so your gut gets support that makes this feel like a real meal, not a quick shake.
Curbing cravings is the part owners talk about most, and the chocolate flavor is the clear crowd favorite. The taste wins people over consistently, with buyers reporting it tastes rich without being overly sweet or chemical, and that it blends well with ice, banana, or fruit. It is gluten-free and skips artificial sweeteners, colors, and preservatives.
The recurring trade-off, as buyers report, is the price: “Really works. My only complaint is the price.” Owners frame it as a premium investment that justifies itself through the nutritional density and reliable results, especially as a breakfast replacement on busy mornings.
What earns the top spot
- Rich chocolate taste praised for balanced sweetness
- 6g fiber plus probiotics and enzymes for digestion
- 30 servings per container delivers long-term value
The honest trade-off
- Premium price point sits well above budget options
- Slightly chalky texture when mixed with water alone
Reach for this if: you want a dependable, nutrient-dense meal replacement that curbs cravings and supports digestion — and you are willing to pay for the quality.
Think twice if: your budget is tight, because the per-serving cost is the single most common owner complaint.
2. UpNourish Strawberry Banana Vegan Protein Powder
A budget-friendly vegan shake packing 54 superfoods and 1.5 billion probiotics per serving.
What makes this one stand out is the sheer breadth of what is in each scoop. The 21g of plant-based protein comes alongside 54 superfoods like kale, spinach, blueberry, and goji berry, plus 1.5 billion CFU of probiotics — a heavy hitter for gut health at an entry-level price point.
Owners consistently praise the strawberry-banana flavor and the way it blends with almond milk into a thick, creamy shake with no grit. Owners mention it keeps them full until afternoon and eliminates the 2 p.m. sluggishness, making it a strong breakfast swap. It is lactose-free, dairy-free, gluten-free, with zero sugar and a low-carb profile that fits keto diets.
The flavor is where opinions split slightly — a few find the strawberry note a bit synthetic compared to the coffee version. The 15-serving count is also on the shorter side, so heavy daily users will reorder faster.
Why it wins on value
- 54 superfoods plus probiotics at a budget price
- Thick, creamy mix with almond milk, no grit
- Zero sugar and keto-friendly
Where it cuts corners
- Only 15 servings per container
- Strawberry flavor reads synthetic to some
Who it beats: every pricier vegan shake on fullness and superfood count per dollar — buyers call it a better deal than competitors with the same nutrients.
Look elsewhere if: you need a daily 30-serving tub, since 15 servings disappear fast for committed users.
3. Orgain Organic 25g Protein + 10g Collagen Powder — Vanilla Bean
The 3-in-1 formula stacking 25g of protein with collagen for skin, hair, and joint support.
That mass comes from 15g of organic plant protein plus 10g of grass-fed bovine collagen, a pairing that supports your gut while aiming at your hair, skin, nails, and joints.
Each serving also includes 1 billion probiotics for gut support, and the vanilla bean flavor wins genuine praise for being tasty and filling. Buyers describe it as a satisfying breakfast alternative that mixes easily with fruits and nuts, and it dissolves well in a small blender without turning grainy. It is certified non-GMO, gluten-free, and made without dairy, soy, or lactose.
The honest catch is texture, which splits opinions — some find it silky smooth while others say it lands a little chalky, a common trait in plant-based blends. The compact 1.6-pound tub is also noticeably smaller than the Shakeology container, a 2.4x gap in dimensions that heavy users will notice.
What makes it a standout
- 25g protein with a 10g collagen boost in one scoop
- Behavior praised as tasty and filling for breakfast
- Certified non-GMO and gluten-free
The texture debate
- Some report a chalky aftertaste
- Smaller tub size versus longer-lasting blends
Pick this over: the competition if collagen for skin and joints is a priority — this is the only top pick pairing 10g of it with a full protein dose.
Pass on it if: you hate any chalky note in your shake, since plant-based texture is a known split.
4. Andrew Lessman Secure Soy Complete Meal Replacement — Vanilla
The 12-year-faithful soy shake delivering 21 essential vitamins in a smooth vanilla sip.
This one earns its place through a different lens — it is a complete nutrition drink first, a protein shake second. Each serving combines non-GMO soy protein with dietary fiber and 21 essential vitamins and minerals, and it does it at just 63 calories per serving, making it one of the lightest meal replacements here.
The flavor is the anchor, with buyers reporting a smooth, creamy vanilla that is not overly sweet and mixes easily without clumps or chalk. It keeps people full for hours without bloating, and long-term users — including those on the product for over 12 years — cite its clean ingredient profile and reliable results for weight management.
What you do not get is a probiotic or enzyme complex; this is a straightforward, thoughtfully formulated soy meal replacement rather than a gut-support superfood blend. If you want adaptogens and probiotics, the vegan picks above go further.
Why it endures: a decade-plus of owners still ordering it speaks to a formula that simply works — smooth vanilla, steady fullness, and a balanced 21-vitamin profile at 63 calories.
The limit: no probiotics or digestive enzymes, so it is nutrition-first rather than gut-focused.
5. Vega All-in-One Nutrition Organic Vegan Protein Powder — Unsweetened
The clean-slate vegan shake for mixers who want zero sweetness and full control.
The defining spec here is right in the name — unsweetened. Each serving delivers 20g of organic pea protein with superfoods, fiber, and probiotics, but without any added sweetener, which makes it the pick for anyone who finds Stevia or other alternatives overpowering. You sweeten it yourself, or drink it as-is.
Quality is what owners praise most, noting it dissolves fast in any liquid with no lumps and keeps them full for up to three hours. It is a favorite for post-dental-work liquid diets and for those who want to stay vegan and gluten-free without the cloying sweetness of rival shakes.
The unsweetened taste and slight grittiness require proper blending with milk for best results. It is also a pricier per-serving product than budget vegan options.
Who it serves: the control-freak mixer who wants a clean 20g organic pea base and prefers adding their own sweetness — this is the anti-sweetener standout.
Who it skips: anyone expecting a ready-to-drink sweet shake; this one demands blending and personal flavor work.
6. PlantFusion Complete Meal Replacement — Chocolate Caramel
The greens-heavy plant shake with over 20 superfoods and 6 grams of satiating fiber.
This one focuses on packing in nutrients. You get 20g of plant protein, plus cruciferous greens like kale and watercress, over 20 different organic superfoods, 4.4 grams of omega fats (healthy fats for your heart), and 6 grams of fiber. That combination is designed to keep you full for 2 to 4 hours, and buyers consistently report it does.
What wins people over is the taste; it is the most-mentioned aspect by a wide margin, with the chocolate caramel flavor drawing genuine enthusiasm. It is fortified with 21 wholefood vitamins and minerals including A, C, D, E, K, B12, and B7, and it is made dairy-free, soy-free, gluten-free, and free of major allergens with digestive enzymes added.
The recurring gripe is the earthy undertone — some describe an initial chocolate-grass flavor that improves with blending tricks like adding cocoa, banana, or almond milk. It also thickens fast, so it mixes best with extra liquid and ice.
Why it stands out
- 6g fiber plus greens for long-lasting fullness
- Chocolate caramel flavor widely praised
- Free of major allergens with digestive enzymes
What takes effort
- Earthy flavor notes until you dial in the recipe
- Thickens quickly, needing extra liquid and ice
Best for: anyone with food allergies who wants a greens-and-fiber-dense meal shake and does not mind tweaking the blend to perfect the taste.
Reconsider if: you want a grab-and-go sweet shake; this one rewards a little kitchen effort.
7. FlavCity All in One Protein Shake Powder — Vanilla Latte
The morning-rush shake that fuses 60mg of caffeine with collagen and adaptogens.
This is the all-in-one built for the early riser who wants coffee and protein in one shaker cup. Each serving combines 60mg of natural caffeine, 10g of collagen peptides, and functional mushrooms like Reishi and Cordycecs, replacing your morning coffee and supplement stack in a single scoop — no blender needed.
The taste is the standout, drawing the most owner praise of any aspect, with buyers describing the vanilla latte flavor as smooth, not gritty or chalky, and mixed cleanly in under a minute. It is made with 100% grass-fed whey, is gluten-free with no added sugars, and is third-party tested for purity.
The honest split is value — some find it worth the price given the collagen-plus-caffeine stack, while others call it a waste of money. The vanilla latte flavor is also strong, and some prefer it toned down. If you want a true meal replacement with broad vitamins, this skews more toward a functional coffee-protein hybrid.
The promise: out the door in 10 minutes with caffeine, 10g collagen, and clean whey in one shake — genuinely fewer dishes and zero wait.
The caution: it is a targeted functional shake rather than a full vitamin meal replacement; check if the 60mg caffeine suits your afternoon cutoff.
8. Ka’Chava Whole Body Meal Shake — Coconut Acai
The everything-shake built on peas, sacha inchi, maca, and 85+ superfood ingredients.
Ka’Chava positions itself as the whole-body meal, not just a shake. The formula pulls together pea protein, sacha inchi, maca root, kale, super greens, MCTs, probiotics, adaptogens, digestive enzymes, and functional mushrooms — a density that goes beyond the average meal replacement toward a full nutritional foundation.
The coconut acai flavor earns real enthusiasm, described as rich, creamy, and smooth like a milkshake, with a subtle natural fruit note. Customers note it mixes well in a blender with water, ice, and coconut yogurt, and that it keeps them full for hours. It is non-GMO with no whey, gluten, soy, dairy, or artificial anything.
Value is the recurring negative — this is a premium-priced shake, and the 15-serving tub does not last long for daily users. The flavor also splits people; some find it just okay, not great, and a few note a slightly earthy or grainy texture.
What earns the premium
- 85+ superfoods in a milkshake-smooth blend
- Adaptogens plus probiotics and digestive enzymes
- Coconut acai flavor genuinely praised
Where it stings
- Premium per-serving cost is the top complaint
- 15 servings vanish quickly for daily drinkers
Reach for this if: you want the most complete plant-based meal shake on the market and the premium per-serving cost fits your budget.
Look elsewhere if: you are cost-sensitive; the shorter 15-serving count makes this the priciest daily habit here.
9. Transformation Protein Super Blend — Vanilla
The 30-gram-protein powerhouse pairing egg white, collagen, and 15 billion probiotics.
This is the muscle-focused end of the all-in-one spectrum, and the 30g of protein per serving leads the entire list. That protein comes from a triple-source blend of egg white, collagen, and plant protein, plus 3g of L-leucine — the key muscle-building amino acid — to push recovery and lean mass.
What makes it genuinely all-in-one is the digestive stack: 15 billion CFU of bacillus coagulans probiotics, a strain built to survive stomach acid, alongside digestive enzymes and MCT oil for energy and focus. It is whey-free, soy-free, dairy-free, and gluten-free, blending smoothly with water or milk.
Effectiveness is the top owner praise, with buyers reporting clean mixing, sustained energy, and no bloating or jitters after switching from whey. The honest split is taste — the vanilla is described as creamy by some, but one buyer called it hard to mix with a spoiled-milk note, so flavor perception varies.
The verdict: the biggest protein dose here with a serious probiotic count — the clear pick for gym-goers who want muscle-building power plus gut comfort.
The caveat: flavor is polarizing, with a minority finding the vanilla hard to mix; chocolate may be the safer first tub.
Understanding the Specs
Protein per serving
The headline number, but not the whole story. A 30g serving like the Transformation blend supports muscle building, while 17-20g servings like Shakeology and Vega prioritize meal replacement and fullness. Match the protein count to your goal — gym recovery wants the high end, everyday meal swaps work fine at the lower end.
Probiotics and digestive enzymes
These are what separate a true all-in-one from plain protein. Probiotics and digestive enzymes in formulas like Transformation and Shakeology help your gut break down protein and ease bloating. If you have a sensitive stomach, prioritize a formula with both, like Shakeology or PlantFusion.
