OWYN vs Koia

Overview: OWYN (Only What You Need)

OWYN stands for Only What You Need, and the brand backs that promise with a top-9 allergen-free certification on every product: no dairy, no soy, no peanuts, no tree nuts, no eggs, no fish, no shellfish, no wheat, no sesame. The OWYN protein shake delivers 20g of plant protein per 12oz bottle from a proprietary OWYN protein blend of organic pea protein, organic pumpkin seed protein and organic flax.

OWYN is also one of the few RTDs to include a digestive-enzyme blend (protease and bromelain) for easier protein absorption. Sweetening is monk fruit + organic stevia. The price runs $3.50-$4.50 per bottle in 4-packs and 12-packs at Target, Sprouts and Whole Foods. Flavors span Chocolate, Cold Brew Coffee, Cookies & Cream, Vanilla, Strawberry Banana and seasonal Pumpkin Spice.

Overview: Koia

Koia launched in 2014 and quickly became the plant-based RTD with the most aspirational cold-aisle placement. Each 12oz bottle delivers 18g of plant protein from a blend of pea, brown rice and chickpea protein. Koia sweetens with monk fruit and the entire shake stays vegan, gluten-free and non-GMO.

Koia's calling card is taste. Cacao Bean Coffee, Chocolate Banana, Vanilla Bean and Cinnamon Horchata are bright, dessert-style profiles that hit harder on flavor than most plant-based RTDs. The catch: Koia carries 8g-12g of sugar per bottle (mostly from organic cane sugar), making it less suitable for strict low-sugar diets. Bottle price is $3.50-$4.50, similar to OWYN.

Side-by-Side Comparison

Value Score Comparison

Both brands sit in the premium RTD tier. OWYN slightly outperforms on protein-per-dollar at the 12-pack price, while Koia compensates with broader flavor selection and stronger taste reviews.

• OWYN wins on per-bottle protein (20g vs 18g) and is the easy choice for low-sugar diets.
• Koia wins on flavor variety and on the "do I actually want to drink this" test, which matters more than spec sheets for daily use.

Verdict: Which Should You Choose?

Pick OWYN if:

• You have any of the top-9 food allergies
• You want zero to low added sugar in your RTD
• You want 20g protein per bottle, not 18g
• You value the added digestive enzyme blend

Pick Koia if:

• You prioritize flavor variety and indulgent profiles
• You are okay with 8g-12g of organic cane sugar per bottle
• You shop at Whole Foods or Sprouts and want the broader Koia lineup
• You want a dessert-style RTD instead of a clean post-workout shake
