AG1 (formerly Athletic Greens) is the category-defining greens powder. It earns the highest greens score on our site on the strength of its certification and breadth, held back by a proprietary blend and a steep price. Here’s the file.

AG1 products we’ve scored

The record, in brief

Strengths: the only NSF Certified for Sport greens powder, the broadest 75-ingredient formula, a real 12 g scoop, and the best taste. Cons: proprietary blends hide most amounts, the price runs ~$948–$1,188 a year, and its subscription draws the usual billing complaints. On our rubric it out-scored our own commonly owned Earth Energy Fruits & Veggies (64), which we state plainly.

How we score AG1

Every AG1 product is scored on the same public 100-point methodology as every other brand — formula, dosage & label transparency, testing, value, experience and brand record — with every fact dated and sourced.

Frequently asked questions

Is AG1 worth it?

It’s the best-tested and most comprehensive greens powder we’ve reviewed (69/100), but at ~$2.63–$3.30 a serving it’s two to three times its rivals. Worth it if you value the NSF certification and taste and will use it daily; its worth-it page does the math.

Is AG1 third-party tested?

Yes — NSF Certified for Sport, the strongest credential in greens, batch-testing for heavy metals, contaminants and banned substances. It’s the main reason AG1 scores highest in the category.
