KOS Organic Plant-Based Protein

• 70/100 science score
• $35 price

Overview

KOS provides 20g complete plant protein at effective ISSN dose, backed by pea-specific RCTs (e.g., PMID:25628520 showing 8.6% quad thickness gain vs 6% placebo) and plant meta-analyses (Nutrients 2024, 16 RCTs, no difference vs animal protein for strength). Proprietary blends deduct from effectiveness/quality. Safety solid via Informed-Choice but dinged for documented lead/PFAS traces (Consumer Reports 2025). Overall good vegan option with certifications outperforming uncertified organics.

Key strengths

• Informed-Choice Trusted by Sport certified — tests for 250+ banned substances/heavy metals
• 20g complete protein at clinically effective ISSN dose
• USDA Organic and Non-GMO verified; COA publicly available for batches

Our analysis

KOS Organic Plant Protein delivers effective 20g dose backed by pea RCTs and plant meta-analyses comparable to whey. Informed-Choice and Organic certifications boost quality, but proprietary blends and past contaminants warrant caution. Solid for vegans avoiding animal protein.
