Why we love it
NSF lists AG1 Next Gen as NSF Certified for Sport in 65 g and 390 g packs, with lot numbers published, and AG1 says every batch is tested for more than 280 banned substances.
AG1 has been studied as a finished product, not just as ingredients: three small placebo-controlled trials of 30, 20 and 16 adults measured gut bacteria, micronutrient targets met and blood nutrient levels. AG1 staff co-authored all three.
Garage Gym Reviews and BarBend each named AG1 Next Gen their Best Greens Powder Overall in May 2026, and Fortune rated it 4.5 of 5 in a July 2026 update.
Per AG1, one scoop gives 11 vitamins and minerals at 100% or more of the Daily Value, including 500 mg of vitamin C (556% DV) and 20 mg of zinc (182% DV).

Questions
Is AG1 worth the money?
It depends on what you value. AG1 costs $3.30 a serving one time, $2.63 monthly or $2.30 on the 90-day plan, per AG1, against $0.50 to $1.75 for three greens powders at Target. The premium buys an NSF Certified for Sport listing and trials of the product itself. Garage Gym Reviews scored its price 1 of 5.
Is AG1 NSF Certified for Sport?
Yes. NSF lists AG1 Next Gen, the 13 g scoop formula, as NSF Certified for Sport in 65 g and 390 g packs, with lot numbers published (checked October 6, 2026). AG1 also says every batch is tested for more than 280 banned substances.
What has research on AG1 measured?
Three small trials, all co-authored by AG1 staff. In 30 adults over 4 weeks, AG1 enriched two probiotic taxa without changing clinical safety markers. In 20 trained adults, it raised micronutrient targets met by 2.8 versus placebo. In 16 adults, one serving raised blood levels of 9 of 10 measured nutrients.
Has AG1 had any safety signals or recalls?
No recalls: openFDA food recall data listed none with AG1 as the recalling firm (checked October 6, 2026). An independent 2026 analysis of 48,840 FDA supplement adverse event reports flagged a preliminary liver enzyme signal for AG1 in 2023 to 2025, which its authors framed as a signal for further study, not a confirmed risk.
Why do older AG1 reviews read differently?
AG1 changed its formula. AG1 says reviews before January 2025 reflect an earlier formula, which used a 12 g serving with 7.2 billion CFU; Next Gen uses a 13 g scoop with 10 billion CFU. Garage Gym Reviews testers scored Next Gen's taste 3 of 5, lower than the old formula.
