AG1 wins on ingredient depth (75 ingredients, NSF Certified for Sport), but Bloom wins on cost-per-serving and taste ratings. If you want the most comprehensive daily greens and budget isn't a concern, AG1. If you want a solid product at 40% of the price, Bloom delivers.

Ingredient Breakdown
AG1's 75-Ingredient Formula
AG1 is built around four core proprietary blends: a Raw Superfood Complex (greens, algae, antioxidant fruits), a Nutrient Dense Extracts blend (adaptogens, mushrooms, herbs), a Digestive Enzyme & Super Mushroom Complex, and a Dairy-Free Probiotic blend delivering 7.2 billion CFU.
The sheer breadth is AG1's most defensible differentiator. You're getting spirulina, chlorella, barley grass, wheat grass, broccoli flower, carrot, beet, spinach, acerola cherry, Rhodiola rosea, ashwagandha, coenzyme Q10, artichoke leaf, alpha-lipoic acid, and dozens more — all in a single scoop. No greens competitor approaches this ingredient count.
The catch: AG1 uses proprietary blends, which means individual ingredient doses aren't disclosed. You know you're getting spirulina, but not how many milligrams. For evidence-based consumers who want to verify therapeutic doses, this is a real limitation.
Bloom's Streamlined 30-Ingredient Stack
Bloom takes a leaner approach — fewer blends, cleaner label, and better taste optimization. Its formula includes a greens blend (spirulina, spinach, kale, broccoli), a digestive support blend (apple cider vinegar, ginger, inulin), and a 1 billion CFU probiotic.
What Bloom lacks compared to AG1: adaptogens, mushroom extracts, antioxidant fruit concentrates, and liver support ingredients. If you're looking for a greens + adaptogen + probiotic all-in-one, Bloom doesn't cover that ground. But if you're stacking Bloom with dedicated adaptogens (like ashwagandha capsules) separately, you can build a comparable stack for less money overall.
Bloom's edge: The simpler formula is easier to tolerate for sensitive stomachs, and the taste profile (fruit punch, mango, coconut) consistently rates higher than AG1's earthy, grassy flavor.
Probiotics: 7.2B CFU vs 1B CFU
AG1's probiotic dose is meaningfully higher. Research generally suggests 1–10 billion CFU is effective for general gut health maintenance, so both products fall in a reasonable range — but AG1's 7.2B CFU gives more buffer. Neither product competes with dedicated probiotic supplements (which can deliver 50B+ CFU), but for casual gut support within a greens formula, AG1's dose is the stronger offering.
Price Comparison: The Real Math
This is where the conversation gets uncomfortable for AG1 advocates. The cost differential over time is significant.
At subscription pricing, AG1 costs approximately $948/year (30-day supply at $79 on subscription). Bloom costs approximately $420/year (30-day supply at ~$35 on subscription). That's a $528 annual difference — enough to add a quality magnesium, omega-3, and vitamin D stack on top of Bloom and still come out ahead financially.
The "Bloom + Extras" Stack (Same Budget as AG1)
- Bloom Greens — ~$420/year
- Ashwagandha 600mg (adaptogen coverage) — ~$80/year
- Lion's Mane mushroom capsules — ~$120/year
- Dedicated probiotic 25B CFU — ~$120/year
- Total: ~$740/year — still $208 cheaper than AG1 alone
This isn't to say AG1 is overpriced in absolute terms — it's a premium product with premium testing and formulation costs. But the value argument for AG1 depends heavily on whether convenience (one scoop instead of multiple supplements) is worth $500+ per year to you.
Third-Party Testing
This is a category where AG1 has a genuine, meaningful advantage over most competitors — including Bloom.
AG1 holds NSF Certified for Sport certification, which is the most rigorous third-party certification available for supplements. NSF tests for over 200 substances prohibited by major athletic organizations, verifies label claims, and audits manufacturing facilities. Athletes subject to drug testing (NCAA, WADA, professional leagues) specifically look for this certification. It's not cheap to obtain, and AG1's consistent renewal of it signals genuine commitment to quality control.
Bloom carries Informed Sport certification, which is also a respected third-party program (used widely in the UK and increasingly in the US). It tests for banned substances and label accuracy. It's a solid credential — just one tier below NSF Certified for Sport in terms of recognition among elite athletes and institutions.
For the average consumer, both certifications mean the product is what the label says it is. For competitive athletes, NSF Certified for Sport is the gold standard and AG1 wins outright here.
Taste & Mixability
AG1 has a distinctive flavor: earthy, slightly bitter, with a green vegetable undertone that most people either come to appreciate or never fully enjoy. It mixes cleanly in 8–10oz of cold water with a brief stir. Some users add it to smoothies to mask the taste. Reviews consistently rate it around 4.1/5 — respectable, but not a flavor standout.
Bloom formulates aggressively for taste. Available in flavors like mango, coconut, apple berry, and original, Bloom skews sweeter (stevia + monk fruit) and avoids the grassy undertone entirely. Aggregate taste ratings land around 4.4/5. If palatability is a key driver of daily compliance — and it often is — Bloom has a real edge here.
Mixability is comparable. Both dissolve fully in water with minimal clumping. Neither requires a blender.
Who Should Choose AG1?
- Athletes subject to drug testing who need NSF Certified for Sport verification
- People who want the most comprehensive single-product daily foundation and aren't managing a budget
- Those who want meaningful adaptogen coverage (ashwagandha, rhodiola) built into their greens
- Biohackers and optimizers who value ingredient breadth over cost-per-serving
- Anyone who currently takes 5+ separate supplements and wants to consolidate
Who Should Choose Bloom?
- Budget-conscious consumers who want solid greens coverage without paying premium pricing
- People who struggle with the taste of typical greens powders and need a flavored option
- Those already taking dedicated adaptogen and probiotic supplements who just want a greens base
- New supplement users who want to start with something affordable and approachable
- Anyone who plans to build a custom stack and doesn't need all-in-one convenience
Final Verdict
AG1 is the better product by most objective measures — more ingredients, higher-dose probiotics, adaptogens, and the strongest third-party certification in the category. It earns its premium positioning. But "better product" and "better value for you" aren't the same thing. For most people who aren't competitive athletes and who are willing to take one or two additional targeted supplements, Bloom delivers 80% of the functional benefit at 40% of the cost. The right choice depends on whether you're optimizing for comprehensiveness or for value.
