AG1 is the nutrient-dense, NSF Certified for Sport pick at about $3.33 a serving, the one most people use to replace a multivitamin. Bloom Nutrition is the flavored, budget option at roughly a third of the price, the one you are more likely to actually drink every day. The choice really comes down to trust and completeness versus taste and cost.
Both are huge sellers, and most head-to-head reviews bury the real decision in a wall of numbers. So here is the short version first, then the detail. AG1 wins on disclosed nutrition and third-party testing. Bloom wins on flavor, price, and how easy it is to buy. Neither is a scam, and neither is perfect.

AG1 (Athletic Greens)
AG1 is the original all-in-one greens powder and still the brand most others get compared against. One 12-gram scoop packs 75 ingredients, including 10 vitamins and 10 minerals listed with real amounts on the label (think 420mg of vitamin C and 15mg of zinc), plus roughly 7 to 9 billion CFU of probiotics. It is unflavored, with a mild grassy-vanilla taste that most people tolerate but few love.
The bigger draw is trust. AG1 is NSF Certified for Sport and screened against more than 280 banned substances, so it clears the bar for drug-tested athletes. That, plus the broad vitamin and mineral spread, is why a lot of people use it in place of a daily multivitamin. The catch is the price: about $3.33 per serving, roughly $79 a box on subscription or close to $99 one-time for 30 servings.
Best for: athletes, anyone who wants a greens powder to double as their multivitamin, and shoppers who want the strongest third-party testing signal and will pay for it.
Bloom Nutrition
Bloom Nutrition took the opposite approach: make a greens powder people genuinely want to drink. Its Greens & Superfoods comes in 8 flavors, including Mango, Strawberry Kiwi, and Berry, with a smaller 5.44-gram serving built around 30+ ingredients across 7 proprietary blends. It leans on multiple digestive enzymes (amylase, protease, cellulase, and lipase) for the bloating-and-digestion angle it is known for. Founded by fitness creator Mari Llewellyn, it grew fast on TikTok and is now easy to find on its own site, Amazon, and Walmart.
The trade-off is what you can see and verify. Bloom's label lists almost no specific vitamins or minerals, the 7 proprietary blends hide the exact per-ingredient doses, and there is no NSF or sport certification. What you get in return is taste and value: around $1.08 to $1.33 per serving, with the standard tub near $39.99, a 60-serving size around $74.99, and 10% off plus free shipping if you subscribe.
Best for: budget-conscious shoppers and beginners who will only stick with a greens powder if it actually tastes good and is simple to buy.
How they compare
Ingredients and doses
AG1 lists 75 ingredients and, importantly, shows real amounts for its 10 vitamins and 10 minerals. Bloom lists 30+ ingredients but tucks them inside 7 proprietary blends, so you rarely see how much of anything you are getting. Worth knowing: both brands use proprietary blends, so neither is fully transparent. AG1 simply discloses more. A fair criticism of AG1 is the opposite problem, that cramming 75 ingredients into 12 grams may leave some of them under-dosed.
Taste and flavors
This one is not close. Bloom offers 8 flavored options and consistently scores higher on taste in side-by-side reviews. AG1 comes in a single unflavored version that most testers call drinkable but earthy. If whether you will keep drinking it daily depends on flavor, Bloom has the edge.
Price per serving
AG1 runs about $3.33 per serving. Bloom runs roughly $1.08 to $1.33. Even with AG1's subscription discount, it stays around three times the cost of Bloom. Over a year that gap is real money, so be honest about whether the extra nutrition and certification are worth it for you.
Third-party testing
AG1 is NSF Certified for Sport and screened against 280+ banned substances, which is the meaningful difference for competitive or drug-tested athletes. Bloom does not carry that certification. If verified purity matters to you, this is AG1's clearest win.
Overall value
Value depends entirely on what you want the powder to do. If you treat it as a multivitamin-plus-greens with sport-grade testing, AG1's price is easier to justify. If you want a tasty daily nutritional boost without overthinking doses, Bloom delivers most of the everyday benefit for about a third of the cost.
Which should you buy?
If you are an athlete, get drug-tested, or want a greens powder that can replace your multivitamin, buy AG1. The NSF Certified for Sport status, the disclosed vitamin and mineral doses, and the broader formula are what you are paying the premium for.
If you are on a budget, new to greens powders, or know you will only keep up the habit if it tastes good, buy Bloom. The flavors, the ~$1 per serving cost, and the easy retail availability make it the one most people will actually finish.
A quick honesty check before you commit: both hide some doses behind proprietary blends, so do not expect a fully transparent label from either. AG1 gives you more disclosure and the testing; Bloom gives you taste and a far lower price. Pick the trade-off that fits how you will really use it.
Frequently asked questions
Is AG1 worth the extra money over Bloom?
It depends on what you want from it. If you will use AG1 to replace a multivitamin and you value NSF Certified for Sport testing, the higher price is easier to justify. If you mainly want a tasty daily greens drink, Bloom delivers most of that for about a third of the cost.
Which tastes better, AG1 or Bloom?
Bloom, for most people. It comes in 8 flavors and scores higher on taste in side-by-side reviews. AG1 is unflavored with a mild grassy-vanilla profile that testers usually call drinkable rather than enjoyable.
Is Bloom third-party tested like AG1?
No. AG1 is NSF Certified for Sport and screened against more than 280 banned substances. Bloom does not carry that certification, so if verified purity is a priority, AG1 has the clear advantage.
How much does each cost per serving?
AG1 is about $3.33 per serving (roughly $79 on subscription or $99 one-time for 30 servings). Bloom is roughly $1.08 to $1.33 per serving, with the standard tub near $39.99. Bloom is consistently about three times cheaper per serving.
Can AG1 or Bloom replace a multivitamin?
AG1 is the stronger fit, because it lists 10 vitamins and 10 minerals with actual amounts on the label. Bloom lists almost no specific vitamins or minerals, so it works better as a general daily boost than as a true multivitamin replacement. Check with your doctor if you rely on specific nutrients.
Why is AG1 so much more expensive than Bloom?
AG1 carries a larger 12-gram serving, a 75-ingredient formula, NSF Certified for Sport status, and screening against 280+ banned substances, all of which add cost. Bloom uses a smaller serving and a lighter formula, and competes on taste and price instead.
Do AG1 and Bloom use proprietary blends?
Yes, both do. The difference is disclosure. AG1 still lists real amounts for its core vitamins and minerals, while Bloom keeps most of its 30+ ingredients inside 7 proprietary blends, so you see far fewer exact doses on the Bloom label.
