Thorne Plant Protein Review: Sport-Certified Dairy-Free Option
August 10, 2026
Best for: Athletes who need a dairy-free protein powder and value NSF Certified for Sport.
Thorne Plant Protein provides 22 g of protein per serving from pea, brown rice, and chia. It is a sensible option for people avoiding dairy, and the NSF Certified for Sport credential is a major strength for tested athletes. Its trade-off is the premium price and a more complex ingredient profile than a plain unflavoured powder.
What stands out
• 22 g plant protein per serving.
• Pea, brown rice, and chia protein sources.
• NSF Certified for Sport.
• Recently listed at $52 for 30 servings, about $1.73 per serving before tax or offers.
What to consider
Taste, sweeteners, and texture are highly personal with plant blends. Check the exact flavour label, allergen information, and current price. It is a plant-protein option, not a direct nutritional equivalent of a whey isolate.
Verdict
A strong sport-certified choice for a dairy-free buyer who accepts the higher price. See the full comparison in Best Protein Powder: How to Choose a Formula Worth Using: https://keysupplements.com/best-protein-powder-how-to-choose-a-formula-worth-using/.
