OWYN is a plant-based nutrition brand that provides allergen-friendly formulas that give you a more accessible way to support your daily protein needs. Its product range includes ready-to-drink shakes, complete nutrition shakes, and coffee-protein hybrids.
The brand offers multiple formats, providing you with flexibility depending on how you prefer to combine protein into your day. It claims that its offerings may support better muscle recovery, enhance energy levels, and help manage weight.
In this review, we’ll take a closer look at the brand’s product offerings, the advantages and limitations of the brand, and what consumers say about their experience to help you decide whether it fits your needs.
As per the official website, OWYN offers allergen-friendly, dairy-free, gluten-free, soy-free, and nut-free formulations. It aims to provide ready-to-drink shakes and mixable powders designed for everyday nutrition as well as higher-protein needs.
The brand’s shake lineup includes several categories, including Protein Shakes in flavors such as Dark Chocolate, Smooth Vanilla, Strawberry Banana, Cold Brew Coffee, and Cookies & Creamless. These come in 12-bottle packs and are also available in multiple variety sets, including combinations like Dark Chocolate + Cold Brew Coffee + Cookies & Creamless or Strawberry Banana + Smooth Vanilla + Dark Chocolate. The range also features seasonal releases like Pumpkin Spice.
OWYN’s Pro Elite High-Protein Shakes include flavors such as Chocolate, Smooth Vanilla, Sea Salted Caramel, and No Nut Buttercup. This higher-protein approach continues in the powder category through Pro Elite Protein Powders available in Chocolate and Vanilla, offered in both 12-serving and 27-serving tubs.
The brand also covers functional nutrition through its Doubleshot Protein Coffee Shakes, which pair plant-based protein with caffeine. These shakes are available in flavours like Mocha Latte, Vanilla Latte, and Caramel Macchiato, which may provide energy support.
The Pro Elite High Protein Shake range provides 32g of protein from OWYN’s protein blend, which includes pea protein, organic pumpkin seed protein, and flaxseed oil.
Pea protein supplies essential amino acids commonly used to support muscle recovery and strength development. Organic pumpkin seed protein contributes additional plant-based amino acids along with minerals naturally found in pumpkin seeds.
The makers added flaxseed oil as it contains ALA, a plant-derived omega-3 fatty acid that supports cellular and metabolic functions. These shakes also contain prebiotics that may help the growth of good gut bacteria.
Pro Elite High Protein Shakes come in Smooth Vanilla, Chocolate, No Nut Buttercup, Sea Salted Caramel, and mixed variety packs.
OWYN’s Protein Shakes provide 20g of plant-based protein with a low-sugar, allergen-friendly formula. These shakes contain a multi-source protein blend, superfood greens, and vegan omega-3s.
They come in flavors such as Dark Chocolate, Smooth Vanilla, Strawberry Banana, Cookies & Creamless, Pumpkin Spice, and Cold Brew Coffee. The protein comes primarily from organic pumpkin seed protein, naturally rich in arginine, which supports nitric oxide production and vascular function.
Pumpkin seed protein also contains minerals like magnesium and zinc, which contribute to ATP energy production, DNA synthesis, and immune activity. Its peptides may become available for muscle repair and enzyme formation.
The included greens blend contains broccoli, spinach, and kale. Broccoli provides sulforaphane precursors that activate Nrf2 pathways for antioxidant defense. Spinach contributes dietary nitrate, which converts to nitric oxide to support muscle efficiency and endurance. Kale contains vitamin K for blood clotting and bone metabolism.
For sweetness, the brand uses monk fruit extract, which contains mogrosides that do not behave like sugar and do not raise glucose levels.
As per the official website, OWYN Protein Powders support muscle recovery and energy with 20g of plant-based protein per serving in Chocolate and Smooth Vanilla flavors.
The blend includes pea protein, pumpkin seed protein, and chia. Pea protein is naturally rich in BCAAs — leucine, isoleucine, and valine — which support muscle protein synthesis.
Chia may contribute ALA for cell membrane structure and provides soluble fiber that forms a gel during digestion, helping slow carbohydrate absorption.
The formula includes Bacillus coagulans MTCC probiotics to help maintain gut microbial balance by producing lactic acid, which may support digestion and nutrient breakdown.
OWYN’s Pro Elite Protein Powders offer 30g of vegan protein with nine essential amino acids and 5.5g BCAAs, available in Chocolate and Vanilla.
The OWYN Amino Acid Blend supplies both BCAAs and all essential amino acids for protein synthesis. Isoleucine and valine may support energy regulation and glucose uptake. Lysine aids collagen formation and calcium absorption, while threonine supports connective tissue structure.
The Vitamin/Mineral Blend includes vitamin C for collagen formation and antioxidant protection, and vitamin E for stabilizing cell membranes during oxidative stress.
Retinyl palmitate (vitamin A) supports immunity and epithelial integrity. Zinc oxide supplies zinc, which supports DNA synthesis and protein construction.
According to the official website, Doubleshot Protein Coffee Shakes combine 20g of plant-based protein with 180mg of caffeine to support energy and mood.
Available flavors include Vanilla Latte, Caramel Macchiato, and Mocha Latte. These shakes aim to resemble café-style drinks without added sugars or heavy creamers.
They may support muscle mass retention by supplying essential amino acids and may promote satiety by slowing digestion, which helps prevent midday energy dips.
Since protein supports tissue repair and enzyme activity, these shakes provide a morning protein source useful for recovery or convenience during busy routines.
High-Protein Complete Nutrition Shakes provide 26g of plant-based protein plus 23 vitamins and minerals. They come in Chocolate and Vanilla.
The formula includes riboflavin (B2) and thiamine (B1), which help convert carbohydrates into ATP. Copper gluconate supports red blood cell formation and antioxidant enzyme activity.
The shakes also include manganese sulfate, which helps activate enzymes involved in connective tissue formation and carbohydrate metabolism.
Potassium iodide provides iodine for thyroid hormone production, which regulates metabolism. Vitamin K1 supports normal blood clotting and works with vitamin D in calcium regulation.
The combination of protein, vitamins, and minerals helps support steady energy, recovery, and nutrient balance.
OWYN’s Balanced Nutrition Shakes offer 20g of plant-based protein and 23 vitamins and minerals. Protein influences weight management through several mechanisms, including the thermic effect of food, which increases calorie burn during digestion.
Protein also triggers satiety hormones such as peptide YY and GLP-1, which help signal fullness and reduce the likelihood of overeating.
OWYN has a broad retail presence because its products are stocked across many national stores and online platforms. The brand’s ready-to-drink protein shakes, including the 20 g protein line and the Pro Elite 32 g line, are available in major grocery chains such as Kroger, Target, Walmart, Publix, and Whole Foods Market. The products are also found in club stores, convenience outlets, and specialty nutrition sections, which allows the brand to reach people with different buying habits.
In addition to physical retail, OWYN has strong placement on large e-commerce platforms. Its full assortment of protein shakes, protein powders, and meal replacement products is sold through its own website as well as through major online marketplaces. The website offers all flavors and formats, including multipacks and variety packs, which support people who prefer direct delivery or recurring orders. The presence of the same product lines across physical stores and online platforms creates a consistent shopping experience and helps strengthen the brand’s visibility.
OWYN claims that all of its products are made without the 9 allergens, which include dairy, soy, gluten, wheat, eggs, peanuts, tree nuts, fish, shellfish, and sesame. These claims suggest that the product line may be suitable if you have multiple sensitivities or diagnosed food allergies.
The brand also claims that its entire range is non-GMO and certified vegan, indicating that the formulas use plant-based ingredients without genetically modified or animal-derived components. It highlights using plant protein sources such as pea protein, pumpkin seed protein, and chia in its offerings, which are naturally free from many common allergens found in whey, casein, soy, or nut-based proteins. OWYN also claims that every production batch goes through allergen testing to verify the absence of cross-contamination before products are released.
OWYN does not offer any personalized formulas or custom nutrition adjustments across its product line. It provides the same fixed options, such as the OWYN 20-gram Protein Shake, the Elite 35-gram High Protein Shake, and the Plant Protein Powder for every user.
The brand uses a preset mix of pea protein, pumpkin seed protein, flax, and greens, and does not allow for changing protein amounts, adding functional ingredients, or creating blends that match individual goals. For example, the Elite Shake always contains 35 grams of protein and 180 calories.
OWYN also does not provide any tools that help you build a personalized nutrition plan. No questionnaire helps evaluate your fitness level, dietary needs, or digestive sensitivities, and the website does not generate custom bundle recommendations based on your profiles. This means people with different needs, such as high-calorie bulking, low sugar weight management, or specialized recovery nutrition, will receive the same products as casual users.
OWYN promotes its plant-based shakes as clean, allergen-friendly, and easy to digest, but it has not published clinical trials or long-term studies on its own products. Shakes like the 20 g Protein Shake, Elite 32 g High Protein Shake, Pro Elite Multi Source Protein Powder, and Complete Nutrition Shake rely on general nutrition science, but no research tests how these exact formulas work in real life. The brand does not provide peer-reviewed studies on muscle recovery, nutrient absorption, strength, post-workout soreness, or endurance compared with whey or other plant proteins.
OWYN also highlights its eight allergen-free manufacturing processes, but it does not share clinical data showing how the shakes perform for people with digestive issues or food sensitivities.
The protein blend includes pea, pumpkin seed, and flax, yet there are no studies explaining how well this mix supports amino acid uptake or muscle protein synthesis over time. The brand also has not published long-term user studies that monitor changes in body composition and training progress.
Koia focuses on plant-based shakes made around clear nutrition categories, including Nutrition Shakes, Elite Shakes, Protein Powders, Protein Shakes, and Kids Shakes. These groups have a defined purpose, such as Nutrition Shakes offering 21 vitamins and minerals, Elite Shakes delivering 32g of protein, and Protein Powders supplying 20g of plant protein, 6g fiber, and 3g sugar per serving.
The brand also features a Kids line that provides 9g of plant protein and remains free from the nine major allergens. Across the site, Koia consistently highlights traits like plant protein, low sugar, prebiotic fiber, non-GMO, and gluten-free, reflecting a straightforward approach focused on clean ingredients and daily convenience.
Koia also highlights that its shakes require no refrigeration, strengthening their emphasis on portability. It uses a retail locator showing stores like Walgreens, Fresh Pick, and Olive Organic Market, emphasizing in-store accessibility.
OWYN, on the other hand, offers a wider range of shake formats and nutritional tiers — from Protein Shakes and Pro Elite High Protein Shakes to Coffee-Protein hybrids such as Mocha Latte and Caramel Macchiato. The brand leans heavily into online ordering, subscriptions, and customizable bundles.
The key difference is structure and depth: Koia keeps its product categories simple and consistent, focusing on core nutrition, while OWYN expands into varied formulas for high protein, balanced nutrition, complete nutrition, and caffeinated protein blends.
Rebbl and OWYN both offer plant-based options, but the structure and purpose of their product lines differ. Rebbl organizes products into Proteins, Awake, Balance, and Revive, each combining protein with functional botanicals.
The Awake+ line pairs 20g of protein with lion’s mane in flavors such as Cold Brew Latte, Matcha Latte, and Lavender Tea Latte. The Balance line includes options like Maca Mocha, while Revive includes reishi-based blends such as Reishi Chocolate and Reishi Vanilla.
Rebbl’s 20g protein options include Dark Chocolate, Hazelnut Chocolate, Strawberries & Creme, Oatmeal Cookie, Vanilla, and Chocolate Peanut Butter Banana. It also offers 26g shakes (Chocolate, Vanilla, Cookies & Creme, Latte, Churro) and 32g shakes (Vanilla, Chocolate, Cookies & Creme). Many are USDA Organic, low sugar, vegan, or Non-GMO Verified.
OWYN maintains a broader lineup, including Protein Shakes, Pro Elite High Protein Shakes, Doubleshot Protein Coffee Shakes, High Protein Complete Nutrition Shakes, Balanced Nutrition Shakes, and multiple powders. Flavors include Smooth Vanilla, Dark Chocolate, Strawberry Banana, Cookies & Creamless, and Cold Brew Coffee.
OWYN also offers protein powders in various tub sizes and emphasizes allergen-friendly standards and Non-GMO Project Verified claims. Its formulas are soy-free, dairy-free, gluten-free, and peanut-free, though not fully organic like many Rebbl options.
Sustainability marks another difference:
– Rebbl uses 100% recycled rPET bottles and redesigned its ribbed bottle to reduce plastic waste by an estimated 100,000 lbs annually.
– OWYN highlights clean ingredient sourcing but shares less detail about packaging sustainability.
Processing methods further distinguish them. Rebbl uses flash pasteurization, a gentler thermal process suitable for herbal ingredients. OWYN does not focus on processing methods in its branding.
Overall, Rebbl emphasizes functional botanicals, organic sourcing, and sustainability, while OWYN offers a wider array of high-protein shakes and powders with strong allergen-friendly assurances and clean, simple nutrition.
To assess OWYN, we started by looking at the brand’s age, background, and product range. The brand focuses on allergen-friendly, vegan-certified nutrition and offers protein shakes, protein powders, and small on-the-go drinks made with pea, pumpkin seed, and flaxseed protein.
It currently holds a 4.8 rating on Tenereteam, but this score is based on a limited number of reviews, which provides little insight into broader customer satisfaction. On the Better Business Bureau, the brand does not have an accreditation or rating, leaving little available information to understand reliability.
To evaluate OWYN, we reviewed customer feedback from Amazon between 2024–2025 across the brand’s products. Pro Elite Vegan High Protein Keto Shake holds a 4-star rating based on 11,853+ reviews. Many users appreciate the 32g protein content, clean ingredients, and easy digestibility, especially for those following keto diets or managing specific health needs.
Several users found the flavors generally acceptable and the shake helpful for meeting daily protein intake. At the same time, texture concerns such as thickness or slight chalkiness appear consistently, and some note that the price point is higher than comparable options.
For the Pro Elite Vegan 30g Plant-Based High Protein Powder, which maintains a 4-star rating from 7,066 reviews, customers highlight its light consistency, good mixability, and gentle impact on digestion. Users appreciate the added probiotics and relatively high protein density.
However, many customers mention a monk fruit or stevia-like aftertaste, and slight grittiness is referenced across multiple feedback.
The OWYN Protein Shake, High Protein Complete Nutrition Drink, holds a 4.2 rating based on 936 reviews, with feedback centered on balanced nutrition and improved flavor in newer formulations. Consumers note that the product offers a smooth taste profile.
The customer feedback suggests that the brand performs reliably in providing clean, plant-based nutrition with strong digestibility and solid protein content. At the same time, texture, sweetener aftertaste, premium pricing, and transparency expectations remain consistent areas for improvement.
OWYN focuses on offering plant-based shakes that avoid the top allergens, using ingredients such as pea, pumpkin seed, and chia to provide complete protein sources. These formulas remain free from dairy, soy, gluten, peanuts, and other major allergens.
The brand offers ready-to-drink formats and simple ingredient lists that support everyday convenience. Its wide retail availability also makes it easy for you to find the full assortment without relying on a single store or platform.
However, the reliance on pea protein in brand offerings may lead to digestive discomfort for some people, and the natural thickness of certain blends results in texture and sweetness levels that vary more than expected. OWYN also offers fixed formulas without personalized nutrition options, so you receive the same blends regardless of your goals, preferences, or sensitivities.
The brand gives you an allergen-friendly, plant-based option with straightforward features and everyday practicality. It's also essential to consider that potential digestive concerns could be possible from OWYN’s offerings.
