The 4 Best Protein Powder 2026

What we love

• You want a whey protein whose heavy-metal test results are actually published, batch by batch, so you can verify what you are drinking.
• You care about clean lead numbers for something you might drink daily, since this landed in Consumer Reports' cleanest tier for lead.
• You are a competitive or drug-tested athlete who needs NSF Certified for Sport verification.
• You want no added sugar and a lean isolate that is gentle on a sensitive stomach.

Worth knowing

• You need a plant-based protein, since this is a dairy whey.
