AG1 vs Bloom vs Athletic Greens vs Organifi
Side-by-side specs on the 4 most-searched greens powders. Note: AG1 and Athletic Greens are the same product (rebrand in 2022). We compare AG1, Bloom, Organifi, and Greens First as the genuinely-distinct top 4.
Quick answer
It depends on what you need. AG1 (Athletic Greens) is the broadest single-product convenience play with NSF Certified for Sport testing, but $79-99/month makes it 2-3x the cost of alternatives. Bloom is the best-value option ($30-50) with decent flavor variety but lower probiotic CFU + only 1 named strain. Organifi is the strongest adaptogen stack (1500mg ashwagandha) and the only stevia-free option, but contains no probiotics. Greens First has the strongest clinical-provenance pitch but lower brand awareness. Per-serving costs range from $1.00 (Bloom) to $3.30 (AG1).

Pick by use case
AG1 / Athletic Greens
Best for: Single-product convenience seekers, athletes needing NSF Certified
Caveat: Most ingredients sub-therapeutic dose due to broad blend; expensive
Bloom Greens & Superfoods
Best for: Budget-conscious users wanting decent flavor, social-media discovery
Caveat: Lower probiotic CFU, only 1 named strain, lower adaptogen doses
Organifi Green Juice
Best for: Stevia-averse users, adaptogen-focused stack, USDA organic preference
Caveat: No probiotics — would need to take separately
Greens First Superfood Powder
Best for: Clinical-provenance buyers, mild flavor preference
Caveat: Lower brand awareness than AG1/Bloom
The honest framing — what these products do + don't do
All four products are functional supplements, not vegetable replacements. Per Holscher 2020 (Advances in Nutrition), the US adult fiber gap is ~15g vs. the 25-38g recommended — and these powders provide 1-2g/serving, closing about 5-10% of the gap at best. The Hernandez 2019 / Cox 2019 evidence base for general microplastic + vegetable nutrition does NOT support "30 servings of vegetables in one scoop" marketing claims.
Where they DO have RCT support: bloating reduction (Ford 2014 meta-analysis, probiotic strains), postprandial digestion (Money 2011, digestive enzymes — only AG1 + Greens First contain them in meaningful doses), and baseline antioxidant capacity (Kim 2014, polyphenol-rich formulas). For the full evidence breakdown, see our honest greens powder evidence review.
Bottom-line dollar logic: if you're using greens powder for bloating/gut symptoms, Bloom at $30-50 delivers ~70% of AG1's benefit at 40% of the cost. If you specifically need NSF Sport certification (competitive athletes) or have proprietary-blend skepticism, AG1 is worth the premium. If you're stevia-averse or specifically want high-dose adaptogens, Organifi is the right pick. For most consumers: Bloom for value, Organifi for stevia-free adaptogens, AG1 only if you need the testing certification.
FAQ — Greens Powder Comparisons
Quick answer
Yes. 'Athletic Greens' rebranded to 'AG1' in late 2022. Same product, same formula, same company (Athletic Greens, Inc.). The bottle now says 'AG1 by Athletic Greens.' If you see a 'vs' comparison treating them as separate products, that's outdated content.
Quick answer
AG1 leads on probiotic CFU (~7.2 billion) but uses only 2 named strains (L. acidophilus + B. bifidum). Greens First has 2 billion CFU with 2 strains (L. acidophilus + L. rhamnosus). Bloom has 1 billion CFU with 1 strain (Bacillus subtilis). Organifi contains NO probiotics. For IBS-specific bloating relief, Ford 2014 meta-analysis suggests multi-strain probiotic formulas outperform single-strain — AG1 and Greens First win on this axis.
Quick answer
For most consumers, yes. Bloom delivers ~70% of AG1's functional ingredient overlap at 40% of the cost ($1.00-1.67/serving vs $2.63-3.30/serving). The main trade-offs: Bloom has 1 vs AG1's 2 named probiotic strains, 1 billion vs 7.2 billion CFU, no NSF Sport certification, and lower adaptogen doses. If those gaps don't matter for your use case (bloating relief, daily veggie placeholder), Bloom is the better value.
