Orgain Organic Protein Plant-Based is a widely available vegan protein powder built on a pea, brown rice, and chia seed protein blend. It's USDA Certified Organic and Non-GMO Project Verified, positioning it toward buyers who prioritize organic sourcing and plant-based ingredients over maximum protein purity or absorption speed. It's one of the most recognized names in the plant-protein category, sold at major retailers including Amazon, Target, and Costco.

Plant-based protein blends like this one generally have a less complete amino acid profile than whey isolate when using a single plant source — Orgain addresses this by combining pea, brown rice, and chia, which together cover all nine essential amino acids more completely than any single plant source alone. It absorbs somewhat more slowly than whey isolate and typically has a denser, less 'clean' mixing texture than a microfiltered whey isolate, which is a near-universal tradeoff across the plant-protein category rather than a flaw specific to this product. Protein-per-serving is lower here (21g) than most of the whey isolates in our lab-tested lineup (23-28g).
This is a reasonable fit for vegans, vegetarians, or anyone avoiding dairy who wants an organic, widely available option without needing to research a smaller or harder-to-find plant-protein brand. It's not the pick if your priority is maximum protein-per-scoop or the fastest possible absorption — our lab-tested whey isolates outperform it on both, but obviously aren't an option if you're avoiding animal products.
The protein blend (organic pea, organic brown rice, organic chia seed) is combined with an organic creamer base (acacia gum, sunflower oil, inulin) for texture and mouthfeel, since plant proteins on their own tend to mix thinner and grainier than dairy-based proteins. Sweetening varies by flavor — some use organic stevia and monk fruit extract, others (like the Iced Coffee flavor) get some sweetness and caffeine from real coffee beans. The listed fiber content (around 7g per serving in some flavors) is notably higher than any whey product in our lab-tested lineup, a direct benefit of the plant-based ingredient base.
Yes — while pea, brown rice, and chia individually have amino acid limitations, combining all three results in a blend that provides all nine essential amino acids, per the amino acid profile Orgain publishes on its own product pages.
No — it's formulated as a vegan product with no dairy-derived ingredients, based on the ingredient list published by the manufacturer.
Plant-based proteins are frequently priced comparably to or slightly higher than mid-tier whey per serving, partly reflecting the cost of organic certification and the more complex multi-source protein blend. Check current retailer pricing, as it fluctuates.
