An honest comparison of two popular daily supplements. We cover price, ingredient quality, transparency, and what you actually get for your money.
Last updated: March 2026
Fireblood is a 39-ingredient daily supplement with full dose transparency, chelated bisglycinate minerals, active vitamin forms, and all 9 essential amino acids. AG1 is a 75-ingredient greens powder that hides most doses inside blends, uses some cheaper mineral forms, and includes zero amino acids. Fireblood costs $62/mo on the 90-day plan compared to AG1’s $79/mo subscription price (as of March 2026).
The quick verdict
AG1 is a well-known greens powder with solid branding and a pleasant taste. But it hides most of its ingredient doses behind blends, uses some cheaper mineral forms, and skips amino acids entirely. Fireblood lists every single dose on the label, uses chelated minerals and active vitamins across the board, and includes all 9 essential amino acids. It also costs $17 less per month on the 90-day plan.
AG1 groups most of its 75 ingredients into blends where individual doses are not shown (verify at drinkag1.com). You cannot tell whether you are getting a research-backed dose or a token amount of any given ingredient.
The label lists names like “Alkaline, Nutrient-Dense Raw Superfood Complex” and “Nutrient Dense Natural Extracts” with a total blend weight. But not the dose of each ingredient inside. This practice is legal and common in the supplement industry. It does not help you make informed decisions about what you are taking.
Fireblood takes the opposite approach. Every single ingredient has its dose printed on the label. 39 ingredients, 39 doses. You can cross-reference each one against the published research yourself.
Why do ingredient forms matter in supplements?
Two supplements can contain the same mineral at the same dose and deliver very different results. The form determines how much your body actually absorbs.
Take magnesium. Magnesium oxide is cheap to manufacture and has an absorption rate around 4% (Firoz & Graber, 2001, Journal of Clinical Pharmacology; Ashmead, 2012, Amino Acid Chelation in Human and Animal Nutrition). Magnesium bisglycinate is chelated (bound to an amino acid), which helps it survive your stomach acid and actually reach your cells. Studies show chelated forms can absorb at rates 5-10x higher than oxide forms.
Fireblood uses chelated bisglycinate forms for all 8 minerals. AG1 uses a mix that includes some oxide forms (see AG1 supplement facts). For vitamins, Fireblood uses active forms across the board: P5P for B6, R5P for B2, methylcobalamin for B12, and L-5-MTHF for folate. These are the forms your body can use directly, without converting them first. This matters especially for people with MTHFR gene variants, who struggle to convert folic acid into usable folate.
Does AG1 have amino acids?
No. AG1 contains zero amino acids. Fireblood includes all 9 essential amino acids (the ones your body cannot make) plus Taurine, Glycine, and Proline.
EAAs play a role in muscle protein synthesis, recovery, neurotransmitter production, and immune function. If you are taking AG1, you need a separate amino acid supplement to get what Fireblood already includes in one scoop.
That is an extra bottle, extra cost, and extra pills or powder every day.
What AG1 does well
AG1 is not a bad product. It is worth being honest about where it earns its reputation.
Taste. AG1 genuinely tastes good. Probably the best-tasting greens powder on the market. If you have tried other supplements and quit because you could not stomach them, AG1 solves that problem. Fireblood is built for function and makes no apologies about taste.
Track record. AG1 has been around since 2010. That is over a decade of consumer feedback and multiple formula iterations baked into the product.
Greens and adaptogens. AG1 includes whole food powders, mushroom extracts, and adaptogens that Fireblood does not. If getting superfood powders in your daily scoop matters to you, AG1 covers more ground there.
NSF certification. AG1 carries NSF Certified for Sport, a rigorous third-party testing standard. Fireblood is GMP certified and third-party tested through independent labs.
Fireblood vs AG1 ingredient forms
Cheaper forms like magnesium oxide have absorption rates as low as 4% (Firoz & Graber, 2001), meaning most of what you swallow goes unused. Here is how the two products compare on form quality.
Yes. Fireblood costs $62/mo on the 90-day plan. AG1 costs $79/mo on subscription (verify current pricing) (prices as of March 2026). A large portion of AG1’s price goes toward marketing, including podcast sponsorships, influencer deals, and digital ads.
Fireblood (90-day)
$62/mo
39 ingredients $1.59 per nutrient/mo
Fireblood (monthly)
$72/mo
39 ingredients $1.85 per nutrient/mo
AG1 (subscription)
$79/mo
75 ingredients listed Most doses undisclosed
AG1 does include greens, adaptogens, and probiotics that Fireblood does not. The question is whether those additions are worth paying more while accepting hidden doses and zero amino acids.
Frequently asked questions
Depends on what you care about. If you want full dose transparency, active vitamin forms, chelated minerals, and amino acids in one product, Fireblood covers more ground. If you want a tasty greens powder with adaptogens and probiotics and you are less concerned about knowing exact doses, AG1 is a solid choice.
AG1 lists 75 ingredients, but many are grouped into blends where individual doses are not shown. More ingredients on a label does not mean more effective doses in your body. AG1 also has significant marketing overhead. Fireblood puts more of the budget into ingredient quality and less into advertising.
We would not recommend it. Both products contain vitamins and minerals, and stacking them could push you over recommended daily intakes, particularly for fat-soluble vitamins like A, D, E, and K. Pick the one that fits your priorities and stick with it.
No. AG1 is formulated for taste. Fireblood is formulated for function. Some ingredients that are good for you taste terrible, and masking them with sweeteners means adding things to the formula that are not there for your health. If taste is your top priority, AG1 wins that one.
Chelated minerals are bound to amino acids (in Fireblood’s case, glycine). This bond protects the mineral through your digestive system so more of it actually reaches your bloodstream. Standard forms like magnesium oxide have absorption rates as low as 4%. Chelated bisglycinate forms absorb significantly better and are gentler on the stomach too.
