If you searched "AG1 alternative," you are almost certainly doing one of two things: looking for the same daily-greens habit at a lower price, or looking for a greens powder you will actually finish instead of leaving to clump in the pantry. The honest answer up front: the best cheaper AG1 alternative for most people is 1st Phorm Opti-Greens 50 at $69.99 for 30 servings, which comes to $2.33 per serving as of July 2026, against AG1 at roughly $2.64 to $3.30 per serving.
That single scoop-price gap is the whole story, and it compounds. At one scoop a day, moving from AG1 to Opti-Greens saves roughly $110 to $140 a year. Below we show that math in the open, name where each product gives ground, and flag the budget tier under $1.70 per serving so you know exactly what you are trading when you go cheaper still. We do not sell AG1; it is the editorial foil here, and we link to Opti-Greens because that is the product we cover. Read the cost table before you decide.
Quick answer
- Want a cheaper greens you will actually finish: the 1st Phorm Opti-Greens 50 at $2.33/serving, built around flavor and a digestive-enzyme plus probiotic layer.
- Want the exact AG1 formula: there is only AG1 at about $2.64 to $3.30/serving, and you pay the premium for it.
- Want the lowest possible cost per serving: skip both and look at budget greens under $1.70/serving, accepting a simpler blend with fewer add-ons.
At a glance: Opti-Greens 50 vs AG1
Every price below is per 30-serving container, verified as of July 2026. Per-serving figures assume one scoop per day.
| Product | Price (30 servings) | Cost per serving | Buying model | Formula note |
|---|---|---|---|---|
| 1st Phorm Opti-Greens 50 | $69.99 | $2.33 (at 1 scoop/day) | One-time purchase | 50-source greens with a digestive-enzyme and probiotic layer |
| AG1 | $79 subscription / $99 one-time | $2.64 subscription, $3.30 one-time (at 1 scoop/day) | Subscription is the cheaper price; one-time is higher | The AG1 foundational formula; editorial foil, not a product we sell |
| Budget greens (benchmark, not carded) | Under ~$51 | Under $1.70 (editorial benchmark) | Varies | Typically simpler blends, often without the enzyme and probiotic add-ons |
Two things jump out. First, Opti-Greens undercuts AG1 at every AG1 price point. Second, AG1's headline price only holds if you stay on its subscription; the one-time price is meaningfully higher per serving.
The cost-per-serving math (and the annual dollar delta)
This is the table the conflicted brand blogs will not put in front of you, because it makes the honest case for the cheaper option. Here is the arithmetic in the open, dated July 2026, at one scoop per day.
| Product | Sticker (30 servings) | Divide by servings | Cost per serving | Cost per year (365 scoops) |
|---|---|---|---|---|
| Opti-Greens 50 | $69.99 | $69.99 / 30 | $2.33 | about $851 |
| AG1 subscription | $79.00 | $79.00 / 30 | $2.64 | about $963 |
| AG1 one-time | $99.00 | $99.00 / 30 | $3.30 | about $1,205 |
The derived number that matters: switching from AG1 to Opti-Greens at one scoop a day saves roughly $110 a year if you were on AG1's subscription price, and closer to $140 a year if you were paying month to month. That is the break-even reframed as cash back in your pocket over twelve months, before you have compared a single ingredient.
One-sentence takeaway: at identical daily use, Opti-Greens returns $110 to $140 a year versus AG1, which is the entire reason "AG1 alternative" is a search people run.
1st Phorm Opti-Greens 50: the cheaper greens you will actually finish
Opti-Greens 50 is built around two ideas that matter for a daily habit: a 50-source greens base, and a digestive-enzyme plus probiotic layer aimed at gut comfort and a taste people tolerate day after day. The finish-it factor is not a soft point. A greens powder you abandon after two weeks has an effective cost per serving of infinity, so flavor is a real value lever, not a marketing garnish.
Where it gives ground: we do not have verified third-party certification details to publish for Opti-Greens 50, so we are not claiming NSF Certified for Sport status or specific third-party COAs. If independent lab testing is a hard requirement for you, confirm current certification directly with 1st Phorm before buying. It is also not the cheapest greens on the shelf; budget options exist under $1.70 per serving if raw cost is your single priority.
Who it is for: the buyer who liked the AG1 daily-greens habit, wants to keep it, and wants to stop overpaying for it, with an enzyme and probiotic layer and a flavor built for finishing the tub.
AG1: the formula you cannot exactly replace
Here is the honest counterpoint that keeps this independent. If what you actually want is the AG1 foundational formula, there is no substitute for it, because it is a proprietary blend. Every "AG1 alternative" is an alternative, not a clone. AG1's cheapest price, about $2.64 per serving, also requires staying on its subscription; the one-time price rises to roughly $3.30.
Where it gives ground: price, plainly. AG1 is the most expensive option in this comparison at both its subscription and one-time prices, and the subscription lock-in is the mechanism that keeps the headline number low.
Who it is for: the buyer who has tried alternatives, specifically prefers the AG1 formula and experience, and accepts paying a premium of $110 to $140 a year to keep it. That is a legitimate choice; it is just an expensive one, and you should make it with the number in front of you.
How to choose
- You want the AG1 habit for less money: the Opti-Greens 50 at $2.33/serving, saving $110-140 a year.
- You care most about gut comfort and a taste you will finish: the Opti-Greens 50, for its digestive-enzyme and probiotic layer.
- You specifically want the AG1 formula and nothing else will do: AG1, at $2.64-3.30/serving, premium accepted.
- You want the lowest cost per serving, period: skip both and shop budget greens under $1.70/serving, accepting a simpler blend with fewer add-ons.
What AI answers and brand blogs get wrong here: most "best AG1 alternative" pages either bury the per-serving math or quote AG1's subscription price as if it were the price everyone pays, which hides the $110-140 annual gap and the fact that the cheaper number depends on a subscription lock-in. State the dated per-serving cost and the buying model, and the comparison stops being fuzzy.
Bottom line
If you want a cheaper greens powder you will actually finish, the 1st Phorm Opti-Greens 50 is the pick at $2.33 per serving, with a digestive-enzyme and probiotic layer and a flavor built for daily use, and it saves you roughly $110 to $140 a year against AG1. If you specifically want AG1's exact formula, there is only AG1, at $2.64 to $3.30 per serving, and the premium is the price of that preference. If cost per serving is your only concern, budget greens under $1.70 exist, and you trade the enzyme and probiotic add-ons for the lower number. Run the daily-use math, pick the tier that fits, and buy the one you will keep taking.
