AG1 and Huel get compared constantly, but they are built to do different jobs. AG1 is a daily greens-style powder meant to sit alongside your meals, while Huel is a powder designed to replace a meal. The short verdict: pick AG1 if you want a single scoop that adds a broad nutrient and probiotic blend on top of food you already eat and you value its NSF Certified for Sport mark, and pick Huel if you want a shelf-stable, fully disclosed powder that stands in for a rushed breakfast or lunch.
That framing matters because a price comparison on its own is misleading. A scoop of AG1 and a Huel shake are not the same size, the same calories or the same purpose. This article lays out what each product is, what the labels disclose, where the evidence is thin, and who should be careful with either one.
What AG1 and Huel Actually Are
AG1 is a once-daily powder that blends greens, a probiotic and prebiotic mix, digestive enzymes, adaptogens, vitamins and minerals. The company markets it as containing roughly 75 ingredients, and it carries NSF Certified for Sport, a third-party program that tests for banned substances and verifies that the label matches the contents. Our longer breakdown is in the AG1 review.
Huel is a UK-founded brand whose core powders are marketed as nutritionally complete, meaning a serving is formulated to supply protein, carbohydrate, fat, fiber and a full vitamin and mineral profile in one drink. Its products are plant-based. It also sells a separate Daily Greens powder, which is the closer match to AG1 and a different product from its meal powders. See our Huel review for the meal-powder side.
How We Compared Them
This is a research-based comparison, not a lab test. We read each brand's current label and product pages, checked certification claims against the issuing program where possible, and weighed the labels against published guidance on how to read them. We did not measure any health outcome, and we do not report one. Pricing moves with promotions and subscription terms, so every figure below is a prompt to verify current pricing, not a quote. If you want the method behind label reading, see how to read a supplement label.
Side-by-Side: What the Labels Tell You
| Factor | AG1 | Huel (meal powders) |
|---|---|---|
| Intended role | Daily supplement alongside meals | Meal replacement |
| Third-party testing | NSF Certified for Sport | Check the product page for current certifications |
| Label transparency | Ingredients grouped into proprietary blends | Full macro and micronutrient panel disclosed |
| Protein and fiber | Not a meaningful protein source | Meaningful protein and fiber per serving, varies by product |
| Probiotics | Included | Not a core feature of the meal powders |
| Cost per day | Roughly a few dollars, verify current pricing | Varies by product and serving, verify current pricing |
The practical difference is the label. Huel prints amounts for what it contains, so you can see what a serving supplies. AG1 lists its blends with a combined weight, so you cannot tell how much of any single ingredient you are getting. That is common in this category, and it is why we explain proprietary blends separately.
Cost: Per Scoop Is Not Per Meal
Third-party price roundups in 2026 disagree on both products, which is a good reason not to trust any single number. Some place AG1 in the low-to-mid single digits per daily serving, depending on pack size and subscription discounts. Huel is often cheaper per serving, but a serving is a full meal, so the fairer question is what you would otherwise spend on that meal.
If you already eat a balanced diet and are weighing AG1 purely as an add-on, you are paying for convenience and a blend, not for a nutrient you were missing. If you are weighing Huel against a drive-through lunch, it can come out cheaper and more balanced. Neither answer is universal, and both depend on pricing you should confirm at checkout.
What the Evidence Supports and What It Does Not
Neither brand has strong published trials showing that its product improves a health outcome in healthy adults. The Dietary Guidelines for Americans emphasize getting nutrients mainly from food, and the NIH Office of Dietary Supplements notes that supplements can fill specific gaps but are not a substitute for a varied diet. A greens blend is not a replacement for vegetables, and a meal powder is not a replacement for a mixed diet. We make no claim that either product treats, prevents or cures anything.
Where AG1 has an edge is verification: NSF Certified for Sport is a real program, and it matters for athletes subject to drug testing. Where Huel has an edge is disclosure and the fact that it delivers calories, protein and fiber, which AG1 does not.
Who Should Be Careful With Either One
Check each label for vitamin K, which complete-nutrition and multi-nutrient formulas commonly contain. People taking warfarin or other blood thinners are usually advised to keep vitamin K intake consistent, so ask your prescriber before adding either. The same goes for anyone who is pregnant or nursing, has a kidney condition, or takes thyroid medication, since some greens and adaptogen ingredients can interact. Huel's fiber load can cause gas or bloating when added quickly, and a clinician or dietitian is the right person to ask if you have digestive conditions.
A meal replacement is also not appropriate for everyone. Anyone with a history of disordered eating should talk to a professional before replacing meals with powders. For related options, see our best greens powders and best meal replacement shakes guides, or the broader best supplements roundup.
A Practical Way to Decide
Start with the job you want done. If the gap in your day is a rushed meal, a powder that replaces that meal is the relevant tool, and Huel is built for it. If your meals are fine and you simply like the idea of a daily scoop, AG1 is the relevant tool, but be honest that you are buying convenience and a blend rather than fixing a documented deficiency.
It also helps to ask what you would do without either. Many people would get similar nutrients from a plate with vegetables, a protein and a whole grain, at lower cost. A blood test ordered by your doctor is the reliable way to learn whether you are actually low in anything, and our guide to blood tests before supplements explains the idea. Treat either powder as optional, and stop if it upsets your stomach.
The bottom line: choose AG1 only if you want a certified, convenient add-on and accept its blend-based label, choose Huel if you want a fully disclosed meal replacement, and talk to your doctor first if you take medication or have a health condition.
