The AG1 vs Bloom Nutrition Greens comparison reveals an uncomfortable truth about the greens powder market: a product that costs $99 per month and a product that costs $40 per tub are not playing the same game. They just happen to be the same color.

AG1 (formerly Athletic Greens) has positioned itself as the premium all-in-one daily supplement -- 75 ingredients, NSF Certified for Sport, 7.2 billion CFU probiotics, and a marketing budget that has seemingly recruited every podcast host on earth. Bloom Nutrition Super Greens entered the market through TikTok virality, sweet fruity flavors, and a price point that doesn't require a second mortgage.

Both are green powders. Both claim to support gut health, energy, and general wellness. But the ingredient lists, testing standards, and dosing philosophies are so different that comparing them requires more nuance than "which one tastes better."

Quick Verdict

AG1 is the better product by a significant margin. It provides clinically relevant doses of vitamins and minerals, discloses most individual ingredient amounts, carries NSF Certified for Sport verification, and uses 75 ingredients across multiple functional categories. The 12-gram serving size alone tells you there's more substance in the scoop.

Bloom is a lighter product -- literally. At 5.44 grams per serving with 30+ ingredients, the math doesn't allow for meaningful doses of most components. It tastes better, costs less, and gets millions of TikTok views. But if you're evaluating these products on what they actually deliver to your body, AG1 justifies the premium.

Key Differences Breakdown

1. Serving Size and Ingredient Density

This is where the comparison starts and, honestly, where it could end.

AG1's serving size is 12 grams. Bloom's is 5.44 grams. That means AG1 delivers more than twice the raw powder per scoop. When you consider that AG1 also has more than twice the number of ingredients, the math gets even worse for Bloom: those 30+ ingredients are sharing 5.44 grams of space.

To put this in perspective, a clinically studied dose of ashwagandha (KSM-66) is 600mg. A meaningful dose of spirulina starts at 1-3 grams. A useful serving of greens blend typically runs 3-5 grams. Bloom's entire serving size is 5.44 grams total -- there is physically not enough powder in the scoop for most ingredients to reach doses that research supports.

AG1 isn't immune to this critique. At 75 ingredients in 12 grams, many individual components are present at sub-clinical levels too. But AG1 at least discloses specific amounts for key vitamins and minerals, and its 12-gram serving provides more room for the greens blend, fiber, and probiotics to reach functional levels.

Winner: AG1. The serving size advantage is decisive.

2. Third-Party Testing and Transparency

AG1 carries NSF Certified for Sport verification, which is the most rigorous third-party testing program available for dietary supplements. This means:

  • Every batch is tested for label accuracy (what it says is in there is actually in there)
  • Screened for 280+ banned substances prohibited by WADA, NFL, MLB, NHL, and other organizations
  • Tested for contaminants including heavy metals, pesticides, and microbial contamination
  • The manufacturing facility undergoes regular GMP audits
  • Random off-the-shelf testing can happen at any time

AG1 also provides a Certificate of Analysis (CoA) accessible to consumers, showing specific test results for contaminants and ingredient verification.

Bloom Nutrition does not prominently disclose its third-party testing practices. The brand doesn't carry NSF, Informed Sport, USP, or other recognized certifications. This doesn't necessarily mean the product is unsafe or inaccurate, but it means you're taking the brand's word for what's in the tub rather than having independent verification.

For anyone who values knowing exactly what they're consuming -- and especially for tested athletes -- this is a significant differentiator.

Winner: AG1, and it's not close.

3. Probiotic Quality

AG1 includes 7.2 billion CFU of probiotics from 5 clinically studied strains. The specific strains are named, and the CFU count is guaranteed at time of consumption (not just at time of manufacture, which is an important distinction -- probiotic viability degrades over time).

Bloom includes 3 probiotic strains: Bifidobacterium bifidum, Lactobacillus rhamnosus, and Lactobacillus acidophilus. These are legitimate, well-researched strains. However, Bloom does not disclose the CFU count, which makes it impossible to evaluate whether the dose is meaningful.

Probiotic research generally suggests that doses of 1-10 billion CFU per day are effective for general gut health support, but the optimal dose varies by strain. Without knowing Bloom's CFU count, you can't assess whether you're getting a therapeutic amount or a label-decoration amount.

Winner: AG1 for disclosed dosing and guaranteed potency.

4. Flavor and Taste Experience

This is Bloom's strongest category, and it's not trivial -- a supplement you won't drink is worthless regardless of its ingredient profile.

AG1 comes in one flavor: the original greens taste. It's earthy, slightly sweet from stevia, with tropical and pineapple notes. Many people genuinely like it. Some find it unpleasant. There are no alternatives. You either adapt or you don't.

Bloom offers 8+ flavors including Berry, Mango, Coconut, Citrus, Mixed Berry, and seasonal options. The flavors are sweet, fruity, and designed to taste like a smoothie rather than a vegetable. They're formulated with stevia and natural flavors, and they taste significantly better to most palates than AG1's single option.

For long-term compliance, flavor variety matters. Bloom's ability to rotate flavors can prevent the "supplement fatigue" that causes people to abandon their greens habit after a few months.

Winner: Bloom, clearly.

5. Ingredient Comprehensiveness

AG1's formula spans five functional categories:

AG1 Complex Key Ingredients Purpose
Vitamins & Minerals Vitamin C, B complex, zinc, selenium, magnesium, and 15+ more Daily micronutrient coverage
Alkaline & Nutrient-Dense Raw Superfood Complex Spirulina, chlorella, wheatgrass, barley grass, broccoli, and more Phytonutrient density
Herbs & Antioxidants Ashwagandha, rhodiola, milk thistle, CoQ10, alpha-lipoic acid Stress adaptation, antioxidant support
Digestive Enzyme & Mushroom Complex Reishi, shiitake, bromelain, and digestive enzymes Gut support, immune function
Dairy-Free Probiotics 5 strains at 7.2 billion CFU Microbiome support

Bloom's formula covers similar ground at a smaller scale:

Bloom Complex Key Ingredients Purpose
Fiber & Greens Blend Chicory root fiber, spirulina, wheatgrass, chlorella, barley grass Fiber, phytonutrients
Fruit & Vegetable Blend Beet, carrot, blueberry, spinach, broccoli, kale Micronutrients from whole foods
Probiotic & Prebiotic Blend Blue agave inulin, 3 probiotic strains Gut support
Adaptogen Blend Ashwagandha, rhodiola, ginseng, astragalus, eleuthero Stress adaptation
Digestive Enzyme Blend Amylase, protease, cellulase, lipase Digestive support

The ingredient categories overlap significantly. The difference is density: AG1's 12-gram scoop can deliver more of each ingredient than Bloom's 5.44-gram scoop can. Both formulas cover the bases; AG1 covers them with more material.

Winner: AG1 for breadth and depth. Bloom for a respectable formula at a lower price.

What They Share

  • Both are greens powders with multiple functional categories -- not just dehydrated vegetables
  • Both include probiotics for gut health support
  • Both include adaptogens like ashwagandha and rhodiola
  • Both include digestive enzymes for nutrient absorption
  • Both are vegan, gluten-free, and sugar-free
  • Both use stevia as a sweetener
  • Both use proprietary blends (though AG1 discloses more individual amounts)
  • Neither replaces a varied, whole-food diet -- they supplement it

Price and Value Analysis

The price gap is significant and deserves honest analysis.

Metric AG1 Bloom
Monthly cost (subscription) $99 ~$40
Price per serving $3.30 ~$1.33
Price per gram of powder $0.275/g $0.244/g
Annual cost $1,188 ~$480

On a per-gram basis, the two products are actually close in price. You're paying roughly the same amount per gram of powder -- AG1 just gives you a bigger scoop with more in it. The question is whether those extra 6.56 grams of powder per serving are worth an extra $2.00 per day.

Here's our take: if you'd otherwise be buying a separate multivitamin ($15-30/month), a separate probiotic ($25-40/month), and a standalone greens powder ($30-50/month), AG1's $99/month starts looking like a consolidation play rather than a luxury purchase. The math works if AG1 replaces 2-3 supplements you'd buy anyway.

If Bloom is your only supplement and you just want basic greens coverage at an accessible price, $40 per tub is hard to argue with. You won't get the dosing depth or testing rigor of AG1, but you'll get something rather than nothing.

Choose AG1 If...

  • You want a comprehensive daily supplement. AG1 covers vitamins, minerals, probiotics, adaptogens, and greens in one scoop. If you're replacing multiple individual supplements, the per-serving cost becomes more reasonable.
  • Third-party testing matters to you. NSF Certified for Sport is the gold standard. If you're a tested athlete or simply want verified quality, AG1 delivers accountability that Bloom doesn't match.
  • You want disclosed dosing. AG1 lists specific amounts for most vitamins and minerals, so you know whether you're meeting your targets. Bloom's proprietary blends make this impossible to assess.
  • You take your supplement routine seriously. At $3.30/day, AG1 attracts people who treat supplementation as a meaningful investment in their health, not an afterthought.
  • You don't mind paying for quality. The premium is real, but it buys genuine differentiation: more ingredients, bigger doses, and independent verification.

Choose Bloom Super Greens If...

  • Budget is your primary concern. At roughly $1.33/serving, Bloom costs less than half of AG1. For people who can't justify $99/month on a supplement, Bloom gets you in the game.
  • Taste matters more than dosing. Bloom's multiple fruity flavors are more palatable to most people than AG1's single earthy option. If you won't drink it, it doesn't matter what's in it.
  • You're new to greens powders. Bloom is an excellent entry point. It introduces the habit of daily greens without the financial commitment that AG1 requires.
  • You want variety. Eight-plus flavors let you rotate and prevent supplement fatigue.
  • You already take other targeted supplements. If you have a separate multivitamin, probiotic, and adaptogen stack, you don't need AG1's all-in-one approach. Bloom adds greens and enzymes without duplicating what you're already taking.

The Bottom Line

AG1 is the better greens supplement. It provides more than twice the serving size, discloses individual ingredient amounts, carries the most rigorous third-party certification available, includes guaranteed-potency probiotics, and covers more nutritional ground per scoop. The $99/month price tag is substantial but justifiable if AG1 replaces multiple supplements in your routine.

Bloom is not a bad product -- it's a good product at a good price. But calling it comparable to AG1 is a stretch. The 5.44-gram serving size limits what any formulator can achieve, the lack of third-party certification is a notable gap, and the undisclosed probiotic CFU count makes the gut health claims difficult to validate.

The honest recommendation: if you can afford AG1 and it replaces other supplements, it's a better investment. If $99/month isn't realistic for your supplement budget, Bloom gets you partial benefits at a fraction of the cost. Some greens are better than no greens.

FAQ

Can AG1 replace a multivitamin?

For most people, yes. AG1 delivers 100%+ of the daily value for most essential vitamins and several key minerals. It covers Vitamin A, C, E, K2, the full B-complex, zinc, selenium, chromium, and more. Where it may fall short is calcium and iron, which are intentionally limited because high doses can interfere with absorption of other minerals. If you have specific deficiency concerns, check AG1's label against your needs -- but for general daily coverage, it's more comprehensive than most standalone multivitamins.

Is Bloom Greens third-party tested?

Bloom does not prominently display third-party testing certifications (NSF, Informed Sport, USP, etc.) on their product or website. The brand may conduct internal quality testing, but without recognized independent certification, there's no way to independently verify that the label matches the contents. This is one of the most significant gaps between Bloom and AG1.

Why is AG1 so expensive?

Three factors: ingredient volume (12g serving with 75 ingredients), sourcing quality (branded ingredients, global supply chain), and certification costs (NSF Certified for Sport involves ongoing testing, audits, and compliance expenses that are baked into the product price). AG1 also spends heavily on marketing (podcast sponsorships, influencer partnerships), which undoubtedly contributes to the price. Whether the premium is "worth it" depends on how many separate supplements AG1 replaces in your routine.

Is there a better third option?

If you want AG1-level quality without the full price, consider Momentous Essential Greens or Transparent Labs Prebiotic Greens. Both offer larger serving sizes than Bloom with more transparent labeling than Bloom and lower prices than AG1. Live It Up Super Greens is another option that dietitians frequently recommend as a mid-range alternative with better value than AG1 and better transparency than Bloom.

Can I mix greens powder with protein powder?

Yes. Both AG1 and Bloom mix well into smoothies with protein powder, though the greens flavor is more noticeable with AG1 due to the larger serving size. Bloom's fruity flavors actually complement many protein shake recipes. Pro tip: blend rather than shake -- greens powders can clump in a shaker bottle, especially AG1's thicker 12-gram serving.
