Field of Greens vs AG1 (2026): Organic Whole Foods vs All-In-One

Both products are marketed to the same broad wellness audience and both promise to cover nutritional gaps in a single daily scoop, which puts them on the same shortlist even though their underlying philosophies are close to opposite. Field of Greens, made by Brickhouse Nutrition, is a lean, USDA-organic, whole-food-only fruit-and-vegetable powder built around a doctor-formulated story. AG1 is a 75-ingredient all-in-one drink spread across proprietary blends, with a stated probiotic count and a long list of vitamins, minerals, adaptogens and mushroom extracts.

The comparison is genuinely useful because it forces a real choice: do you want the simplicity and traceability of a short, whole-food list, or the breadth of a formula that tries to cover greens, probiotics, adaptogens and micronutrients all at once? Neither answer is wrong, but they lead to very different products.

This article works through what each brand publishes as of August 2026, and is explicit anywhere a figure is not published rather than estimating one.

Here is what we can verify from public pricing and label copy as of August 2026. Where a brand does not publish a figure, we leave it stated as such rather than guessing.

Winner: it depends on which Field of Greens price you use. At the one-time canister price of roughly $79.95 for about 30 servings, Field of Greens costs around $2.66 a serving, close to AG1's one-time rate of about $3.30. On subscription, Field of Greens' price drops below that figure, and AG1's subscription rate of $79/month works out to roughly $2.63 a serving — so on subscription pricing the two brands land in a similar range, with the exact gap depending on each brand's current discount, which is worth checking before buying either.

Neither product is dramatically cheaper than the other once subscription pricing is accounted for on both sides. The more meaningful difference is structural: AG1's advertised price is built around its $79 subscription, while Field of Greens' headline figure is the one-time canister price with subscription savings layered on top. Compare like for like — one-time to one-time, subscription to subscription — rather than AG1's subscription rate against Field of Greens' list price.

As always with supplement pricing, check both brands' current checkout pages before deciding, since subscription discounts and canister sizes are the parts of a listing most likely to change between when this was written and when you read it.

Winner: Field of Greens, on structure, though it has its own disclosure gap. Because Field of Greens is built entirely from whole fruit-and-vegetable powders rather than proprietary blends of extracts and isolated compounds, there is no blend total hiding a mix of unknown-quantity ingredients — what you see on the ingredient list is closer to what you are getting, even though individual fruit and vegetable weights within the formula are not published as of August 2026.

AG1 places most of its 75 ingredients inside proprietary blends, so you can read the full list and the blend totals but not how much of any single item is present. That is standard practice across the category and not unique to AG1, but it does mean a shopper cannot verify the amount of any one adaptogen, mushroom extract or herb relative to the others.

Credit where it is due: AG1 publishes more supporting documentation than most competitors and states its 10 billion CFU figure plainly, which is more disclosure than many greens brands offer on the probiotic front specifically. Field of Greens' strength is the other axis — food-based simplicity rather than a stated CFU number.

Winner: AG1, on the numbers it publishes. A stated 10 billion CFU in its Next Gen formula is a specific, verifiable figure, and it is one of the higher published counts in the category. Field of Greens does not lead with a probiotic claim, and we could not find a published CFU figure on its current marketing as of August 2026 — if a stated probiotic count matters to you, check Field of Greens' current label directly before assuming either way.

That said, a stated CFU count is not the only route to gut support. Whole-food fiber, which is central to Field of Greens' formula, can support digestion independently of a formulated probiotic blend, and Field of Greens has never positioned itself as a probiotic-first product — its pitch is organic whole foods, not gut-microbiome specifics.

If you are shopping specifically for a probiotic supplement and want the number in writing, AG1 gives you that. If you are shopping for a short, organic, whole-food ingredient list and are comfortable without a stated probiotic claim, Field of Greens' approach may suit you better.

Winner: it depends entirely on what you are optimising for, which is the honest answer rather than a dodge. If you want the widest possible net of vitamins, minerals, adaptogens, mushroom extracts and a stated probiotic count in a single scoop, and you do not mind a proprietary-blend structure or a subscription-first pricing model, AG1 is built for exactly that and does it at scale.

If you want a short, traceable, USDA-organic ingredient list built from whole foods rather than extracts, and a doctor-formulated brand story matters to you, Field of Greens is the leaner, more food-focused option of the two.

The trap is buying either product expecting it to be the other. AG1 is not trying to be a minimalist whole-food powder, and Field of Greens is not trying to be the broadest ingredient list in the category. Decide which philosophy you actually want before comparing price tags.

Winner: AG1, on what is published. A 90-day money-back guarantee is among the longest windows in the category and fits how these products are meant to be judged — you cannot fairly assess a daily habit over a week or two. Field of Greens' current guarantee terms should be checked directly on its brand page before you buy; we are not going to state a window we cannot verify as of August 2026.

Both brands use subscription pricing to reach their lowest advertised rate, and both charge more for a one-time purchase — AG1 is $99 rather than $79, and Field of Greens' one-time canister price sits above its subscription rate. If you dislike managing auto-ship, compare both brands at their one-time prices rather than their subscription headlines.

One point worth flagging for either brand: subscription discounts and guarantee windows are the parts of a supplement listing most likely to change without much notice, so treat anything stated here as a snapshot and confirm on the current order page before you commit.

Buy Field of Greens if USDA organic certification and a short, whole-food-only ingredient list are what you are shopping for, and you are comfortable with a formula that does not itemise a probiotic count or individual ingredient weights.

Buy AG1 if you want the broadest ingredient list in the category in one scoop, a stated 10 billion CFU probiotic figure, and the longer 90-day guarantee — and subscription pricing does not bother you.

It is also worth saying that plenty of shoppers would be equally well served by a leaner, disclosed-dose alternative to both. If printed blend weights matter to you as much as organic sourcing or ingredient breadth, it is worth reading a wider comparison before settling on either of these two.
