The short answer
Our pick
OWYN Only What You Need 32g Pro Elite Vanilla Flavored Protein…- The most protein per bottle without any dairy in it.
- You want the cheapest per-gram option; plant RTDs cost more.
Key takeaways
- OWYN carries twice the protein: 32 g in 12 fl oz, about 21.3 g per 8 oz, against Orgain's 16 g and about 11.6 g.
- Orgain's 240 calories are the point of it, not a flaw — it is built to stand in for a meal you could not face.
- Neither listing prints a fiber number, so treat any added-fiber expectation as unconfirmed until you read the panel.
- A 0 g sugar shake that tastes sweet is using a high-intensity sweetener — read the ingredient list, because that is where people's tolerance actually differs.
- Lactose intolerance is not a dairy allergy. If lactose is the issue, an ultra-filtered dairy bottle may suit you better than either of these.
Pick by your situation
| If your situation is… | Pick | Why |
|---|---|---|
| You need the most dairy-free protein per bottle | OWYN Pro Elite | 32 g in 12 fl oz, about 21.3 g per 8 oz, with 0 g sugar on the label. |
| You have barely eaten all day | Orgain Vegan | 240 calories and over 22 vitamins and minerals alongside 16 g of plant protein. |
| You react to top-9 allergens | OWYN Pro Elite | The label states the product is tested and validated for the top 9 allergens. |
| You suspect carrageenan is your problem | Orgain Vegan | The listing states no carrageenan, which makes switching a cheap experiment. |
| Lactose is the issue, not dairy itself | Core Power Elite | Ultra-filtered and lactose free on the label, and denser per ounce than either plant bottle. |
| You want fiber specifically | Ensure Max Protein | It is a dairy bottle, but it is the one here that prints a fiber figure: 4 g with a prebiotic. |
Each pick is one of the products compared below — a shortcut by situation, not a separate recommendation.

Most people arrive at plant shakes from one of two directions: dairy stopped agreeing with them, or they do not eat animal products at all. Those two readers need different things from this page, and the two best-known bottles in the category happen to answer different questions anyway.
Before the picks: severe or persistent abdominal pain, vomiting that stops you keeping fluids down, signs of dehydration, allergic symptoms, vision changes, or pain that wraps around to your back are never a shopping problem. Call your prescriber or seek urgent care. Nothing here is medical advice.
The plant bottles, with two dairy baselines
The fourth column is ours, derived from protein per bottle and bottle size — no label prints it. Everything else is read off the listing.
| Shake | Protein | Bottle size | Protein per 8 fl oz | Base | Sugar |
|---|---|---|---|---|---|
| OWYN Pro Elite | 32 g | 12 fl oz | About 21.3 g | Plant protein, top-9 allergen friendly | 0 g |
| Orgain Vegan | 16 g | 11 fl oz | About 11.6 g | Organic pea and chia | — |
| Ensure Max Protein | 30 g | 11 fl oz | About 21.8 g | Milk protein | 1 g |
| Premier Protein | 30 g | 11.5 fl oz | About 20.9 g | Milk protein | No added sugar |
The two dairy rows are there as a yardstick, not as picks. They answer the question people actually have: how much am I giving up by going plant? On protein density, the answer for OWYN is almost nothing — about 21.3 g per 8 oz against 21.8 and 20.9. On Orgain, the answer is about half, and deliberately so.
The two bottles are not doing the same job
OWYN Pro Elite is a protein bottle. Its label leads with 32 g of dairy-free protein, all nine essential amino acids, zero sugar, no artificial sweeteners or sugar alcohols, zero net carbs, and top-9 allergen testing. It is the densest dairy-free option in our catalogue and it is priced like the premium product it is.
Orgain Vegan is a nutrition bottle. Its label leads with 16 g of organic pea and chia protein, over 22 vitamins and minerals, a fruit-and-vegetable powder blend, and 240 calories — the highest calorie figure in the category. On a small appetite, calories are not automatically the enemy. A bottle that carries 240 of them alongside a vitamin load is doing something a zero-sugar protein bottle is not.
Rule of thumb: if the day's protein is short, reach for OWYN. If the day's food is short, Orgain is the bottle that fills more of the gap.
The fiber question, answered honestly
Plant shakes are widely assumed to bring fiber with them, and this is where we have to be careful rather than helpful-sounding. Neither the OWYN nor the Orgain listing we hold prints a fiber figure. Orgain's does state no carrageenan, non-GMO, gluten-free, no soy ingredients, no lactose or dairy ingredients, and certified organic. OWYN's states zero net carbs. Neither gives us a number we are entitled to publish.
For contrast, Ensure Max Protein does print one: 4 g of fiber with a prebiotic. That is a dairy bottle. If fiber is specifically what you are after, the honest route is the fiber supplements shelf, taken gradually and with fluid, rather than hoping a plant shake quietly covers it.
FDA's own label guidance is a useful frame here: fiber is a nutrient to get more of, soluble fiber slows digestion and the rate nutrients are absorbed, and insoluble fiber speeds movement through the digestive system. Those are different effects, and "plant-based" tells you nothing about which one a bottle delivers.
Sweeteners, and why texture threads never end
A shake at 0 g sugar that still tastes sweet is sweetened with something. FDA's sweetener page sets the scale: steviol glycosides run 200 to 400 times sweeter than table sugar, monk fruit extract 100 to 250 times, sucralose about 600 times. A tiny quantity does the work, which is why these bottles carry almost no sugar and few calories from it.
Tolerance for those sweeteners is intensely personal, and it is the single most common reason someone abandons a shake they otherwise like. The ingredient list is the only place that question gets answered, and it takes ten seconds to read.
Texture is the other recurring theme, and is genuinely harder to make smooth than whey. In r/Zepbound and r/WegovyWeightLoss shake threads, the repeated advice is not a particular brand — it is to drink it cold, to sip it over an hour rather than in one go, and to split a bottle across two sittings if that is what gets it finished. People also describe combining a shake with cold brew or high-protein milk to raise protein without raising volume much, which doubles as a way to blunt an aftertaste.
One more pattern worth naming: additives. In those same subs, people who react badly to a popular shake often point at carrageenan on the ingredient list and switch to a brand without it. That is an owner-reported pattern, not a demonstrated cause, and we are not going to dress it up as one. Orgain's listing states it contains none, which makes it a cheap experiment if you suspect it. Persistent symptoms are a conversation with your prescriber, not a shopping decision.
Are you actually dairy-free, or lactose-free?
Worth checking before you pay the plant premium. NIDDK describes lactose intolerance as digestive symptoms caused by lactose malabsorption, notes that most people who have it can consume some lactose without symptoms, and is explicit that it is a different thing from a milk allergy, which is an immune system disorder. It also estimates that about 36 percent of people in the United States have lactose malabsorption.
If lactose is the problem, an ultra-filtered lactose-free dairy bottle like Core Power Elite may be both cheaper per gram and easier on your stomach than a plant shake. If dairy protein itself is the problem, or you do not eat animal products, then these two bottles are your shelf, and OWYN is the protein one.
Where each fits in a week
OWYN is the bottle to keep for the morning after an injection, when appetite is lowest and you want the day's protein handled before it gets away from you. Orgain is the bottle for the day you have not eaten properly at all — vitamins, calories and 16 g of protein, in something you can drink slowly. Neither replaces chewing, and both are worth more alongside resistance training than on their own.
Your next step
If neither bottle fits, a powder lets you set the volume yourself.
Frequently asked
The questions that keep coming up
Is OWYN or Orgain better for protein?
OWYN, clearly. It carries 32 grams in a 12 fluid ounce bottle, about 21.3 grams per 8 fluid ounces, against Orgain's 16 grams and about 11.6 grams. Orgain is built around calories and micronutrients rather than protein density.
Do plant protein shakes have fiber?
Some do, but neither of these listings prints a fiber figure, so we will not state one. If fiber is the goal, a dedicated fiber supplement introduced gradually and with fluid is the honest route.
Why does a zero sugar shake still taste sweet?
Because it uses a high-intensity sweetener. FDA puts steviol glycosides at 200 to 400 times the sweetness of table sugar and monk fruit extract at 100 to 250 times, so a very small amount does the job. Which one a bottle uses is on the ingredient list.
Are plant shakes easier on the stomach than dairy ones?
Not automatically. If lactose is your issue, an ultra-filtered lactose-free dairy bottle may suit you better. If dairy protein itself is the issue, or you eat no animal products, then plant is the right shelf. It is worth knowing which of the two applies to you.
Why is plant protein grittier?
Pea and chia protein do not go into suspension as smoothly as whey or milk protein. The workarounds people describe most are drinking it cold, sipping it over an hour, and mixing it with coffee or another liquid rather than drinking it neat.
