AG1 Review (90 Days In): Is It Worth $99 a Month?

I paid $99 for the first month of AG1, then $79/month for two more on subscription. Ninety days in, here is what I actually noticed, what I didn't, and whether I will keep the autoship running into Q3.

This is not a press tin. The bottle, the metal scoop, the welcome card with my name on it — all of it bought at retail. I have no relationship with the company, and after this review I will not have one.

The Verdict

Rating: 3.6 / 5 — Recommended only if you would otherwise eat poorly

Buy if: You travel four nights a week, you eat one solid meal a day at best, and the alternative is a daily Diet Coke. Or: you have run the math on a real multivitamin + greens + adaptogen + probiotic stack and the convenience tax of one scoop is worth it to you.

Skip if: You already cook most meals, you take a clinical-grade multivitamin like Thorne Basic Nutrients, or you read the back of the canister and the dose ambiguity bothers you. It should.

One-line summary: AG1 is a solid, expensive, marketing-driven greens powder that will not hurt you and might modestly help you — but at $79-99/month, it is one of the most over-priced supplements in this category, and almost any combination of a real multivitamin plus a separate probiotic plus the food on your plate beats it on cost and on dose transparency.

What this review covers

Ninety days of daily AG1, taken first thing in the morning with cold water, on an empty stomach, before coffee — which is the protocol the bottle suggests and which I followed without deviation. Across that window I logged:

• Daily energy (subjective, 1-10)
• Bowel regularity and stool quality (yes, sorry)
• Resting heart rate and HRV from my Oura Ring 4 (review here)
• A Function Health blood panel at day 0 and day 90 (covered in our Function Health review)

I am a 38-year-old male, ~180 lb, training five days a week, generally eating around 180g protein and a vegetable-heavy diet. I am not the AG1 target customer. The AG1 target customer eats like a 24-year-old in their first sales job.

This review focuses on what the product is, what is actually in the scoop, what changed measurably over 90 days, and whether the price holds up against the alternatives.

What's in the tin

AG1 ships in a 30-serving aluminum canister with a metal scoop and a small "welcome packet." The unboxing is genuinely well-considered, and the canister itself is a nice piece of industrial design. The packaging will absolutely justify a $20-30 premium in the average customer's head. That is the point.

Inside, the powder is fine, slightly granular, and a vivid moss green that smells like grass and faint pineapple. One 12g scoop in 8 oz of cold water dissolves in about 15 seconds with a spoon, 5 seconds in a shaker. The taste is fine. Not good. Fine. It is faintly tropical, somewhat earthy, slightly sweet from stevia. It will not become a thing you look forward to. It will become a thing you do.

Inside that scoop, per the AG1 label, there are 75 ingredients organized into eight "complexes":

1. Alkaline, nutrient-dense raw superfood complex (7.4g)
2. Nutrient-dense extracts, herbs, and antioxidants (2.7g)
3. Digestive enzyme and super-mushroom complex (154mg)
4. Dairy-free probiotics (7.2B CFU)
5. Adaptogen complex
6. Plus a separately listed multivitamin layer with named B-vitamins, vitamin C, vitamin D3 (1000 IU), magnesium glycinate, and more

That is a lot. Critically, the "nutrient-dense superfood complex" is a 7.4-gram proprietary blend — meaning the individual doses of spirulina, chlorella, wheatgrass, alfalfa, etc. are not disclosed. You are told what is in it. You are not told how much. This is the central honesty problem of AG1 and of nearly every greens powder on the market.

Compared to AG1's own claims:

• The multivitamin layer is disclosed and is reasonable — vitamin D3 at 1000 IU, B12 at 8mcg, B6 at 1.5mg, etc. These are normal daily-multivitamin doses, not megadoses.
• The probiotic count (7.2B CFU) is genuine and shelf-stable.
• The adaptogen complex (ashwagandha, rhodiola, eleuthero, etc.) is reasonable on paper, dose-opaque on the can.

This is, in short, a fairly good multivitamin and a probiotic, wrapped inside an undisclosed-dose greens-and-adaptogen blend, sold at premium pricing.

What I actually noticed in 90 days

Days 1-7: Mildly looser stool the first three days, then normalized. Energy unchanged. This is what every probiotic does. Not AG1-specific.

Days 8-30: No subjective change in energy, mood, focus, sleep, or training output. HRV and RHR from Oura unchanged within normal day-to-day noise (±5 ms HRV, ±2 bpm RHR). My morning routine simply now included this scoop. Coffee still did all the work.

Days 31-60: Steady-state. The only thing that changed was that I started missing AG1 days when I traveled and noticed nothing different on those days either. I ran out of single-serve travel packets and forgot to reorder. Nothing happened.

Days 61-90: Function Health bloodwork at day 90 came back essentially unchanged from baseline. Vitamin D up slightly (54 ng/mL vs 47 ng/mL — modest, plausibly seasonal). hsCRP unchanged. Ferritin unchanged. B12 high-normal but already was at baseline. Lipids unchanged. No measurable shift attributable to AG1.

For somebody whose baseline diet is mediocre, the modest D3, B-vitamin, and probiotic doses in AG1 will probably move a needle. For somebody whose baseline is already reasonable, AG1 is functionally a placebo at $79/month.

The cost problem

At the time of writing, AG1 is $99 for a one-time tin, $79 on monthly subscription. That works out to $2.63/day on subscription, $3.30/day standalone.

The honest comparison stack — a clinical multivitamin plus a separate probiotic plus a real adaptogen — costs about $35-45/month if you put a little effort into it:

If you build it yourself, you get fully disclosed doses, third-party testing per batch, and the ability to drop any component that does not work for you. You also get to skip the proprietary "superfood complex" entirely, which is the part of AG1 with the weakest evidence and the most marketing.

If, on the other hand, the entirety of your morning supplement decision is "is the scoop in the canister?" — AG1 is genuinely simpler. That simplicity has a price, and it is roughly $40-60/month over the long run.

Where AG1 is actually good

Three honest wins, because I want this to be fair:

1. Compliance. This is not nothing. The single biggest predictor of supplement efficacy is whether you take it. AG1 nails the user-experience side — one scoop, one shaker, done — better than nearly anything else in the category. For somebody who has tried and failed to take six different bottles, AG1 wins on the only axis that matters: they actually take it.

2. Travel packets. The single-serve packets are genuinely useful. I have a small stash in my dopp kit for trips where I know my diet will collapse. At that specific use case — three to five "I am eating gas-station turkey jerky" days in a row — AG1 is reasonable insurance.

3. The multivitamin layer is honest. Inside the proprietary blend nonsense, the named multivitamin doses on the AG1 label are legitimate. The vitamin D, B-vitamins, magnesium glycinate, and chromium are at clinically sensible doses. If you ignore everything else on the label, you are still getting a competent multivitamin in the scoop.

Where AG1 is misleading

Two honest losses:

1. The proprietary blend. Roughly 60% of the scoop's non-multivitamin mass is undisclosed-dose. You cannot know if you are getting 200mg of ashwagandha or 20mg, 50mg of curcumin or 5mg. This is industry-standard practice and it is bad industry-standard practice. Every supplement I genuinely respect — Thorne, Pure Encapsulations, Nordic Naturals, Momentous — discloses every dose.

2. The marketing tone. AG1's positioning ("foundational nutrition," "the only supplement most people need," etc.) is broader than the evidence supports. There is no randomized trial of AG1 specifically. There are studies of individual ingredients at known doses, almost none of which match what is in the scoop. The implied story — drink this, your nutrition is solved — is not what the science says.

The 90-day verdict

I will not be renewing my AG1 subscription. The math does not work for somebody who already eats reasonably and reads supplement labels.

I would, however, recommend AG1 to exactly two kinds of people:

1. Someone whose current "vitamin routine" is nothing. AG1 is meaningfully better than zero. The D3, B-vitamins, and probiotic alone will probably move bloodwork over six months for the average sedentary office worker.
2. A frequent traveler whose hotel-and-airport diet collapses on the road. The travel packets earn their place in a dopp kit.

For everybody else — and for me — the rational play is a clinical multivitamin like Thorne, a real probiotic, a third-party-tested omega-3, and creatine. That stack is cheaper, fully disclosed, and supported by larger evidence. It is also less fun and less simple than AG1, which is exactly the trade you are making.

FAQ

Is AG1 a multivitamin?

Partly. The disclosed multivitamin layer in AG1 is competent — vitamin D3, B-vitamins, magnesium glycinate, chromium, etc. — at sensible doses. But the rest of the scoop is a proprietary greens-and-adaptogen blend with undisclosed individual doses, so AG1 is best thought of as "a decent multivitamin plus a fairly marketing-driven greens blend, sold together."

Is AG1 worth $99 a month?

For most people who already eat reasonably, no. A separate clinical multivitamin (Thorne) plus a probiotic plus an adaptogen costs roughly the same and gives you fully disclosed doses you can actually act on. AG1 wins on convenience and on travel-friendly packaging, and that is a real product feature — but it is not a $1,200/year health intervention for most users.

Does AG1 replace a multivitamin?

Yes for most users — the disclosed multivitamin layer in AG1 covers the major fat-soluble and B-vitamin bases at reasonable doses. You do not need to double up.

Will AG1 help my gut?

Maybe modestly. The 7.2 billion CFU probiotic blend is real and shelf-stable, but it is a fraction of what a dedicated probiotic like Seed DS-01 (53.6B CFU) delivers. If gut health is the goal, a separate probiotic is better.

AG1 vs Huel?

Different products entirely. AG1 is a supplement powder you add to water; Huel is a meal-replacement designed to provide macronutrients and calories. If you want to skip meals, Huel. If you want vitamins-and-greens, AG1 or a real multivitamin.
