OWYN's Non-Dairy Protein Shake (20 g) is a ready-to-drink, plant-based option positioned for people who need a quick dairy-free protein source. Each bottle provides 20 grams of protein and is marketed as vegan and allergen-friendly; it also contains a Superfoods Greens blend and a measurable omega-3 content. The product is distributed through major retailers and has a companion Pro Elite line with 32 grams of protein per serving.

This review synthesizes hands-on testing and reporting from industry reviewers and journalists: a flat-sample taste test and label analysis from Hone Health, an expert write-up and lab-related notes from Garage Gym Reviews, community and retailer feedback (including a negative retailer review), and Consumer Reports’ broader testing and investigation into heavy metals in protein powders and ready-to-drink shakes.

High-level verdict: OWYN Non-Dairy (20 g) is a convenient, genuinely plant-based ready-to-drink protein with a relatively clean ingredient list, third-party allergen testing, 535 mg omega-3s per serving, and an easy-to-digest profile for many users. The biggest drawbacks are variable flavor reception across flavors, a very small amount of the greens blend despite the label callout, questions raised by industry-wide heavy-metal testing, and some isolated but serious consumer GI complaints. It’s a solid choice for allergen-sensitive users who prioritize convenience and a clean label but not the best pick for anyone wanting the highest-per-serving protein or guaranteed benign GI reactions.

How much protein and nutrients do you get?

Each OWYN Non-Dairy Protein Shake serving provides 20 grams of protein and, per product notes reported in reviews, includes 535 mg of omega-3s. Garage Gym Reviews also states the shakes provide all nine essential amino acids, which means the formulation aims to deliver a complete amino-acid profile despite being plant-based.

There is a higher‑protein sibling in OWYN’s lineup — the Pro Elite variant — which provides 32 grams of protein per serving; reviewers sampled both to compare volume and satiety. If you need more than 20 grams per ready-to-drink serving, consider that Pro Elite option or alternative products.

Clean label and testing, but industry safety questions remain

Reviewers highlighted a relatively clean ingredient list and the absence of artificial sweeteners and sugar alcohols. OWYN’s shakes are formulated to be free from top allergens and Garage Gym Reviews notes independent allergen testing; refrigeration is not required for the product.

However, broader industry testing has flagged heavy-metal contamination in many protein powders and ready-to-drink shakes. Consumer Reports’ investigation found elevated lead and other heavy metals in a number of products, and Hone Health explicitly flagged 'may contain heavy metals' as a caveat — an industry-wide risk to consider and one that should prompt buyers to look for brands that publish third-party contaminant testing.

Tastes vary but chocolate is generally smooth; digestion is usually easy

Hone Health reported a smooth chocolate taste in their sampling, and Garage Gym Reviews noted mixed feedback across flavors. Overall reception is variable by flavor: some testers liked it, others found certain flavors less appealing, so flavor selection matters more than with some other ready-to-drink lines.

Multiple reviewers praised the shake’s easy digestibility, but there are documented consumer complaints: a retailer review cited a user who experienced severe stomach pain and nausea within 30–60 minutes of drinking a vanilla bottle. While many users tolerate it well, those with sensitive stomachs should proceed cautiously.

Ready-to-drink format with broad retail availability

OWYN’s Non-Dairy shakes are sold in single-serve bottles and do not require refrigeration, making them convenient for on-the-go use and gym bags. Hone Health specifically noted availability at large retailers, increasing accessibility for shoppers.

Garage Gym Reviews called out low-carb positioning and the convenience of an allergen-friendly, shelf-stable option. Note, though, that some retailers’ policies and the brand’s sales channels may limit returns for taste dissatisfaction.

Return policies and real-user reports matter

Garage Gym Reviews pointed out that OWYN's ready-to-drink lineup may not be returnable in some channels — a practical downside if you buy multiple flavors and don’t like them. Several community discussion threads and retailer reviews show mixed sentiment on flavor and gastrointestinal tolerance.

A single negative retailer review reported severe GI distress after drinking the shake; while this is not a quantified incidence rate, it is a concrete consumer complaint that prospective buyers with sensitive stomachs should weigh alongside the product’s generally easy-digest reputation.

Pros & Cons

  • ✅ Plant-based, vegan ready-to-drink formula delivering 20 g protein per serving
  • ✅ Formulated to be allergen-friendly and independently tested for allergens (per Garage Gym Reviews)
  • ✅ Contains all nine essential amino acids (per Garage Gym Reviews)
  • ✅ Includes 535 mg omega-3s per serving (noted by Garage Gym Reviews)
  • ✅ Relatively clean ingredient list with no artificial sweeteners or sugar alcohols
  • ✅ Shelf-stable — refrigeration not required, sold through major retailers
  • ❌ Protein 'quality could be better' relative to higher‑protein dairy or OWYN Pro Elite alternatives (Hone Health)
  • ❌ The Superfoods Greens blend is present in only a miniscule amount, per Hone Health’s analysis
  • ❌ Industry-wide heavy-metal contamination has been documented; Consumer Reports’ testing raises safety questions for protein powders and shakes
  • ❌ Flavor reception is mixed across varieties; some testers reported dislike of certain flavors
  • ❌ Some retailers/reviewers report no returns allowed for taste dissatisfaction and isolated reports of severe gastrointestinal reactions

How It Compares to the Competition

  • Muscle Milk — Dairy-based option historically noted for taste but contains whey/dairy, so not suitable for vegans or those avoiding dairy.
  • Premier Protein (ready-to-drink) — Widely distributed protein shakes that were included in Consumer Reports’ broader heavy-metal testing; not a plant-only product.
  • Ritual (protein products) — A supplement brand included in Consumer Reports’ testing updates; differs in formulation approach and often emphasizes published third-party tests.
  • Truvani (protein shakes/powders) — Positioned as a clean-label brand and one of the products mentioned in Consumer Reports’ additional testing; different ingredient and sourcing approach than OWYN.

Who Should Buy This & Who Should Skip It

Buy it if: Buy OWYN Non-Dairy (20 g) if you need a shelf-stable, ready-to-drink plant-based option that avoids common allergens, appreciate a relatively clean label and 20 grams of protein per bottle, and want added omega-3s. It’s a good fit for vegans, people with dairy or top‑8 allergen restrictions, and anyone who values convenience and published allergen testing.

Skip it if: Skip this shake if you require more than 20 grams of protein per serving (consider OWYN Pro Elite at 32 g or other higher-protein RTD options), if you have a history of severe digestive sensitivity (there are isolated reports of acute GI reactions), or if you want a product with publicly posted heavy-metal testing that explicitly clears contaminant thresholds.
