"NSF Certified for Sport ensures quality and safety"
This is a real, independently verified third-party certification confirming the product is tested for banned substances and label accuracy.

"Clinically shown to enrich gut microbiome with 10x more healthy bacteria"
This comes from a small company-funded crossover trial of 40 people over 4 weeks, not independent replication.
-
"Vitamin B12 at 16,667% Daily Value supports energy"
Standard B12 doses of 500-1000mcg already correct deficiency; 400mcg here is fine but the huge percentage is a marketing number, not proof of extra benefit.
Examine.com Vitamin B12 summary -
"75+ ingredients deliver superfood and adaptogen benefits"
Ashwagandha, rhodiola, and milk thistle sit in a 7.5g blend split 20 ways — doses are almost certainly far below the amounts used in clinical trials.
Consumer advice
If your goal is basic nutrient insurance, a store-brand multivitamin plus a probiotic and a fiber/greens supplement will cover most of what AG1 offers for a fraction of the price. AG1's clinical studies are real but small, mostly single-arm or short crossover trials, and heavily funded/run by the company itself — treat the "70% increase in folate" and "10x gut bacteria" stats as preliminary, not definitive. If you value convenience (one scoop vs. five bottles) and don't mind the price, it's a legitimate, well-tested product — just don't expect it to outperform its individual components, and don't expect the "superfood/adaptogen" ingredients dosed in milligrams within a 7.5g blend to do much of anything on their own.
Claims vs Evidence
MODERATE0 of 5 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
