AG1 Review Ingredients, Evidence, Price and Value

This AG1 review is for adults deciding whether a daily greens drink is worth about £79 or $79 a month. This is a source-reviewed guide, not a hands-on lab test. Figures come from drinkag1.com, NSF’s public listing, Trustpilot, and named papers captured on 13 September 2026.

Who this AG1 review is for

AG1 suits people who want one scoop instead of a drawer of single supplements, and who will pay a premium for third-party sport testing. It does not replace meals. It does not replace vegetables. If you want a 400 kcal complete food, look at Huel Black Edition, not this pouch.

Skip AG1 if soy is a problem. The UK label listed lecithin (soy). Skip it if you are under 18, pregnant, or breastfeeding. AG1’s UK page is explicit. Skip it if you already take a zinc supplement. The same page says not to stack other zinc products. Skip it if £79 or $79 a month would squeeze ordinary food.

If the habit you want is “drink more water,” a reminder app is cheaper. Start at WaterMinder or the hydration and nutrition products hub. Protein still belongs on the plate. See our everyday protein guide.

Dated formula and commercial fields

The UK nutrition table captured on 13 September 2026 listed 13 g per day (about one heaped tablespoon or one travel pack). Energy was 172 kJ / 41 kcal. Fat 0.9 g. Carbohydrate 4.4 g, of which sugars 1.2 g. Protein 2.6 g. Fibre 2.5 g. Vitamin C was 420 mg (525% NRV). Vitamin B12 was 50 μg (2000% NRV). Five named bacterial strains were listed with CFU counts “at the time of manufacture.”

Directions on that page: mix one scoop in 250–350 ml of cold water. Refrigerate the opened 390 g bag and use it within 90 days. The caution block said food supplements are not a substitute for a varied diet.

Price, subscription and a year of bills

Keep currencies apart. The UK page showed £79 a month and £2.64 a serving. The US daily-health page showed $79 a month and $99 if you buy once. First-month discounts appear often. We did not lock a promo that may expire tomorrow.

A year of the listed subscription is 12 × £79 = £948, or 12 × $79 = $948, before tax and extra shipping. Travel packs were listed as a dearer format on secondary price explainers. We used pouch figures only.

That is roughly twice the listed monthly bag price of Huel Daily Greens in our sister Huel Daily Greens review. Price is not proof of a better formula. It is the bill.

Ingredients, allergens and privacy

The UK ingredients open with apple powder, pea protein isolate, spirulina, soy lecithin and inulin. Later lines include wheatgrass, barley leaf, chlorella, mushroom powders, steviol glycosides, and vitamin K as menaquinone-7. The label also lists five Lactobacillus and Bifidobacterium strains with CFU at manufacture, not necessarily at the end of shelf life.

AG1’s privacy policy says the company collects account and usage data, uses it to personalise the site, and shares it with service providers you cannot switch off. Some third-party sharing can be limited. AG1 states it complies with the EU-US Data Privacy Framework and the UK extension. That is a shopping-site policy, not a medical record.

There is no required companion app for the scoop. If you still want a drink log, Waterllama and Plant Nanny are separate products with their own store privacy labels.

What independent tests and papers measured

Townsend and colleagues published a double-blind, randomised, placebo-controlled trial in the Journal of the International Society of Sports Nutrition in 2024 (PubMed 39352252; NCT06181214). Thirty healthy adults (15 men, 15 women) took AG1 or placebo for four weeks. Stool analysis found enrichment of Lactobacillus acidophilus and Bifidobacterium bifidum, species the authors said likely came from the product. Digestive quality-of-life scores did not worsen. That is a tolerability note, not an energy claim.

A 2025 crossover paper in the same journal enrolled 20 highly active adults for 14 days of AG1 and 14 days of matched maltodextrin, with a two-week washout. Overall community diversity did not differ by PERMANOVA. Some taxa, including Bifidobacterium animalis and Lacticaseibacillus rhamnosus, were enriched on AG1. A subset lost those shifts after washout. Sample sizes are small. Several authors listed AG1-linked affiliations. The UK marketing footnote says studies used a similar, evolving formula.

NSF’s public Certified for Sport listing for AG1 Next Gen showed a 13 g scoop, 40 calories, and “free of” claims including gluten, dairy, lactose, egg and peanuts on the lots listed there. That listing is a banned-substance and label-claim programme. It is not a clinical outcome trial.

What remains unverified

We did not assay heavy metals. ConsumerLab’s public teaser says it has tested AG1 and published cautions, including comments on metals and liver-injury reports. Those reports do not prove cause. We omit ConsumerLab’s paywalled numbers because we could not verify them.

Also unverified: whether today’s pouch matches the 2024 trial powder, your tax, and any “replaces 15 supplements” price comparison. That comparison is AG1’s own 2025 shopping footnote, not an independent basket audit.

This AG1 review lands here: you pay for a tested, soy-containing scoop with small microbiome trials and a high monthly bill. You do not pay for a meal, a diagnosis, or proof that you will feel different.
