AG1 vs. Huel vs. Green Vibrance: How the Three Greens Powders Compare

AG1, Green Vibrance, and Huel Daily Greens are three of the most-searched greens powders on the U.S. market. They sit in the same category — a daily scoop mixed into water — but their labels are built very differently. AG1 relies on proprietary blends across most of its formula. Green Vibrance discloses every ingredient with its individual amount. Huel lists essential vitamins and minerals by amount but aggregates some botanical groupings. Here's how the three compare on ingredients, transparency, and price.

Quick verdict

AG1 is the most expensive of the three and holds NSF Certified for Sport status. Most of its ingredients sit inside proprietary blends, so individual amounts aren't disclosed. Vitamin D3 and K2 are sold separately as a liquid dropper.

Green Vibrance is priced in line with Huel and discloses every ingredient with its individual amount , no proprietary blends, plus 25 billion probiotics from 12 strains per serving.*

Huel Daily Greens is the most affordable option and lists essential micronutrients like vitamin D, K, iron, and iodine by amount. The scoop is small (8.5 g) for a 91-ingredient panel, so individual botanicals sit well below the doses used in clinical research. It also contains caffeine sources (green tea and green coffee extracts).

What is AG1?

AG1 (formerly Athletic Greens) is a subscription-first greens powder that Athletic Greens Ltd. updated in January 2025 as AG1 Next Gen. It's best known for its podcast and celebrity sponsorships and is marketed as an all-in-one daily foundation.

On the label:

• 75+ ingredients organized across multiple proprietary blends
• Probiotics from Lactobacillus and Bifidobacterium strains
• Prebiotics (inulin), adaptogens, digestive enzymes
• NSF Certified for Sport
• Vitamin D3 and K2 sold as a separate liquid dropper, not included in the main powder

Price: $79 per month on subscription for 30 servings (~$2.63 per serving); $99 for a one-time 30-serving purchase (~$3.30 per serving).

Trade-off to know: most of the ingredient panel is bundled into proprietary blends, meaning you see the total blend weight but not the amount of each individual ingredient inside. This makes head-to-head dose comparisons difficult.

What is Green Vibrance?

Green Vibrance is a plant-based greens powder from Vibrant Health that has been in continuous formulation since 1992 and is currently at Version 22.0. It's a daily scoop mixed into water or a cold beverage.

On the label:

• 65+ functional foods, every ingredient disclosed with its individual amount — no proprietary blends
• 25 billion probiotics from 12 strains per serving*
• 2.5 g of plant-based micronutrients
• 14 antioxidants
• 6 cereal grass varieties
• Non-GMO Project Verified; gluten-free, dairy-free, soy-free, vegan
• No caffeine

Price: $56 for 30 servings (~$1.87 per serving); subscription pricing is lower.

Trade-off to know: because Green Vibrance is a whole-food-based formula stored in the refrigerator or freezer after opening to preserve probiotic potency, it isn't the most convenient of the three for travel. Vibrant Health offers travel packets for that use case.

What is Huel Daily Greens?

Huel Daily Greens is an 8.5-gram-per-scoop powder from Huel, positioned as a broad daily supplement. Its formula lists 91 ingredients spanning vitamins, minerals, whole-food-sourced nutrients, probiotics, adaptogens, and botanicals.

On the label:

• 91 ingredients
• Vitamin D, K, iron, and iodine included by disclosed amount
• Bacillus coagulans probiotic
• Contains ashwagandha, green tea extract, and green coffee bean extract (caffeine sources)
• Additives: tapioca starch, silicon dioxide, guar gum, natural flavors, stevia
• Plant protein from pea protein, chia, and sprouted quinoa

Price: $56.50 for 30 servings, or approximately $45 on subscription (~$1.50 per serving).

Trade-offs to know: the 8.5-gram scoop is small for a 91-ingredient panel, so individual botanicals and adaptogens sit below the doses used in clinical research. If you're avoiding caffeine, the green tea and green coffee inclusions matter — Huel doesn't publish an exact per-scoop caffeine amount.

Proprietary blends: the transparency question

The biggest label difference across the three products is how much you can actually see:

• AG1 relies most heavily on proprietary blends. Total blend weight is disclosed; individual ingredient amounts are not.
• Green Vibrance discloses every ingredient with its individual amount. No proprietary blends anywhere on the label.
• Huel sits between the two: essential vitamins and minerals are disclosed by amount, but some botanical and adaptogen groupings are aggregated.

Proprietary blends are legal under FDA labeling rules. The trade-off is that shoppers can't verify whether any specific ingredient is present at a research-supported dose or a token amount. Full disclosure, the format Vibrant Health calls Truth in Labeling, gives you the same information a formulator or clinician would want to see.

Price comparison at 30 servings

Subscription pricing lowers AG1 to about $2.63 per serving and Huel to about $1.50 per serving. Green Vibrance subscription pricing is also lower than the one-time rate. Prices reflect manufacturer sites as of publication and are subject to change.

Which one to choose

All three are daily greens powders, but the decision usually comes down to two questions:

How much do you want to see on the label? If per-ingredient transparency matters — every dose visible, no proprietary blends — Green Vibrance is the only one of the three that answers that fully. Huel is partial; AG1 discloses least.

What are you willing to pay? AG1 costs roughly 75 percent more per serving than Green Vibrance and Huel at one-time pricing, and about 40–75 percent more on subscription depending on the comparison. That premium goes to a proprietary formula, NSF Certified for Sport status, and the brand's marketing footprint.

Frequently asked questions

Which greens powder is the most affordable?

Huel Daily Greens and Green Vibrance are priced almost identically at the one-time rate — about $1.87–$1.88 per serving for 30 servings. Huel drops to about $1.50 per serving on subscription. AG1 is the most expensive of the three, at about $2.63 per serving on subscription and $3.30 per serving at the one-time price.

Do Huel Daily Greens contain caffeine?

Yes. Huel Daily Greens includes green tea extract and green coffee bean extract, both of which contain caffeine. Huel does not publish an exact per-scoop caffeine amount, so the total per serving isn't listed on the label. AG1 and Green Vibrance do not contain added caffeine.

Does AG1 contain vitamin D and K?

Not in the main powder. AG1 sells a separate liquid vitamin D3+K2 dropper that customers take alongside the powder, rather than including those vitamins in the greens formula itself. Both Huel Daily Greens and Green Vibrance include vitamin D and K in the powder.

Which of these products fully disclose their ingredient amounts?

Only Green Vibrance discloses every ingredient with its individual amount. Huel discloses essential vitamins and minerals with amounts but aggregates some botanical and adaptogen groupings. AG1 uses proprietary blends across most of its label, disclosing total blend weight but not individual ingredient amounts.

Can any of these replace a multivitamin?

All three are marketed as multivitamin alternatives. Whether any of them meets your needs depends on the specific vitamins and minerals you're trying to cover — the practical step is to compare each label's amounts against your daily targets rather than relying on the marketing framing.

Which has the most probiotics?

Green Vibrance lists 25 billion probiotics from 12 strains per serving* on its label. AG1 discloses probiotics from Lactobacillus and Bifidobacterium strains but publishes lower CFU counts than Green Vibrance. Huel Daily Greens contains a Bacillus coagulans probiotic; the CFU count isn't prominently listed on its front-of-label marketing.
