The verdict, first
AG1 wins on the two things that separate greens powders — third-party testing and formula depth — and scored 69/100 to Primal Greens’ 53. AG1 carries NSF Certified for Sport, a rare and meaningful third-party check, and a 12 g blend spanning 75 ingredients. Primal Greens offers a smaller 8 g proprietary blend without that certification. On what you can verify about quality, AG1 is ahead.
Primal Greens’ entire case is price. At $1.72 a serving it undercuts AG1’s $2.63 by nearly a dollar a day — about $330 a year less. Both lean on proprietary blends that hide most individual amounts, so neither is a transparency champion. If budget is the deciding factor and you don’t need sport certification, Primal Greens delivers a greens powder for meaningfully less. If testing and formula depth matter, AG1 justifies its premium.

Testing is the real separator
AG1 carries NSF Certified for Sport — an independent program that tests finished product for banned substances and label accuracy, and one very few greens powders bother to earn. It’s the single biggest reason AG1 sits at 69/100. Primal Greens, as of our check, publishes no equivalent third-party certification we could verify. For a category built almost entirely on proprietary blends, an outside check on what’s actually in the tub is worth real points.
Neither product itemizes most of its ingredient amounts — both hide behind proprietary blends, which we mark down on both. The difference is that AG1 at least submits the finished blend to an outside lab; Primal Greens asks you to take the label on faith.
The price gap, in dollars
Primal Greens costs $1.72 a serving to AG1’s $2.63. Over a year that’s roughly $628 versus $960 — a gap of more than $330. That’s the trade in plain numbers: you can save about a dollar a day by giving up the NSF certification and 4 g of blend. For some buyers that’s an easy call; for anyone who wants the testing, AG1’s premium buys something specific.
Which one fits you
AG1 makes more sense if…
- You want NSF Certified for Sport testing on a greens powder
- A bigger blend (12 g, 75 ingredients) and the higher score (69 vs 53) matter
- You’ll pay a premium for the most-scrutinized product in the category
Primal Greens makes more sense if…
- Price is the deciding factor — about $330 a year less than AG1
- You don’t need third-party sport certification
- You’re comfortable with a proprietary blend, as both here use one
