What You're Actually Buying
AG1 is a micronutrient supplement that you add to your existing diet. It provides vitamins, minerals, probiotics, and adaptogens but essentially no macronutrients. You still need to eat breakfast.
Huel is an actual meal replacement. 400 calories, 40g protein, 7g fiber, plus 26 vitamins and minerals. It can genuinely replace a meal from both a macronutrient and micronutrient perspective.
Vitamin Quality: Surprisingly Close
Both products use L-Methylfolate (the bioactive form) and Vitamin K2 as MK-7. Both use chelated minerals in some positions. On vitamin form quality alone, they're more similar than different.
The critical difference: AG1 doesn't include Vitamin D (selling it separately for $20), while Huel includes it at meaningful levels. For a product that costs 56% more per serving, missing an essential vitamin is a real gap.
Where AG1 pulls ahead: its probiotic blend and adaptogen ingredients (though doses remain undisclosed behind proprietary blends). Huel takes the transparency approach with fully disclosed amounts.
Clinical Evidence
AG1's four completed RCTs are the strongest clinical program in the supplement space. Published research showing improved gut microbiome diversity, better nutrient absorption, and reduced bloating gives AG1 a credibility advantage that most competitors can't match.
Huel has limited published clinical data but benefits from full ingredient transparency. You can independently verify that each nutrient hits research-backed doses because nothing is hidden.
Value per Dollar
At $3.30/serving, AG1 provides vitamins, minerals, and adaptogens in a 50-calorie supplement. At $2.12/serving, Huel provides those same vitamins plus 40g protein, 400 calories, and 7g fiber.
Put differently: $2.12 buys you a complete meal with Huel. $3.30 buys you a supplement that requires you to still buy and prepare a meal on top of it. The total cost comparison isn't $3.30 vs $2.12. It's $3.30 + breakfast vs $2.12.
Bottom Line
Choose AG1 if: You eat well, want the strongest clinical evidence backing your supplement, and prioritize the adaptogen/probiotic profile. You don't need calories or protein from your supplement.
Choose Huel if: You want a complete meal that covers both macros and micros at less than half the daily cost. You value ingredient transparency over clinical studies.
Our take: If you're buying AG1 as a meal replacement, you're overpaying for an underpowered product. If you're buying it as a premium multivitamin supplement, the clinical evidence backs it up. Huel delivers dramatically more nutrition per dollar, but it's solving a different problem.
