AG1 (Athletic Greens) review: Expensive insurance policy that dissolves fast

What I tested

AG1 Daily for 90 days, one scoop every morning around 07:30, usually in 300ml cold water (their shaker bottle is fine, nothing special). Started this in January after my endocrinologist suggested I "stop optimizing code and start optimizing literally anything else"—my HbA1c had crept into pre-diabetic range and my dietary logging revealed I was averaging 1.2 servings of vegetables per day[^1].

I'm not Athletic. I don't do Greens in the wholesome farmer's market sense. But I do respect the idea of reducing surface area for failure, and swallowing 8-12 individual supplement pills every morning had a 40% adherence rate (I logged it).

What actually changed (sample size: one German skeptic)

Energy levels seemed more stable between 14:00-16:00, which used to be my "stare at Slack and achieve nothing" window. Hard to isolate causality—I also fixed my sleep schedule and stopped eating Döner at 23:00—but subjectively, the afternoon trough flattened. Could be placebo. Could be the B vitamins. Could be that I'm drinking 300ml of water first thing now.

Digestive regularity improved (you're welcome for that detail). My partner noticed I stopped getting the 11:00 energy crash that used to require a second coffee.

Blood work after 90 days: HbA1c down from 5.9 to 5.6, which my doctor attributed to "literally everything you changed, not one powder." Vitamin D went from 18 ng/mL to 31 ng/mL[^2]. Hard to give AG1 full credit when I also started walking 8k steps daily, but it didn't hurt.

The expensive part (let's talk about it)

€90 per month. That's €1,080 per year for something I could theoretically replace with frozen spinach, a multivitamin, and a probiotic for maybe €300 annually. The math is bad. I know the math is bad.

Athletic Greens positions this as "comprehensive," but when you look at the label, most adaptogens and extracts are dosed in the 50-100mg range—nowhere near the amounts used in actual studies (rhodiola studies typically use 400-600mg). It's nutrient coverage, not nutrient optimization. Those are different design goals, and the marketing conveniently blurs them.

Also: I've heard their founder on four separate podcasts doing the exact same talking points. That's not third-party credibility, that's media buying.

What actually matters (to me, at least)

It works as a forcing function. One scoop, 30 seconds, done. My previous system had failure modes: forgot to reorder zinc, forgot to take the fish oil, took the magnesium at the wrong time and got digestive distress. AG1 has one failure mode: did I drink the green thing? That simplicity has value, even if I'm overpaying for it.

The ConsumerLab certification is real (I checked the batch numbers). The ingredient sourcing PDF is more transparent than most.

Would I recommend it to someone on a tight budget? No. Would I recommend it to someone who's currently taking zero supplements and has decision fatigue? Maybe.

Verdict: Overpriced nutritional insurance that actually got me to 90-day adherence when nothing else did.
