Best AG1 Alternatives UK: 6 Honest Picks for 2026

AG1 costs £79 a month in the UK on subscription. That is 30 servings. So £2.63 a day. As a one-off pouch it is £97, or £3.23 a day. If you are hunting for the best AG1 alternative in the UK, that number is usually why.

Cheaper is the easy part. Five of the products below cost less per day than we do. One costs a fifth of AG1. The harder question is what you wanted the powder to do.

Why UK buyers look for an AG1 alternative

Price comes first, and it is not close. Good Housekeeping UK tested 13 greens powders in 2026. Its first listed con for AG1 was one word: "Expensive." Seven of those 13 products cost under £30.

Then comes the quieter reason. A month goes by and nothing changes. Healthline's dietitian review says AG1 "may not be worth the cost for people who already take a multivitamin or maintain an overall balanced diet". The same question has run for years on Reddit, in r/HubermanLab, r/PeterAttia and r/Ultramarathon. People are not asking whether AG1 is good. They are asking whether they can feel it.

Credit where it is due, though. AG1 has four published placebo-controlled trials on the finished formula. It holds Informed Sport and Cologne List certification. One 13g serving gives 420mg of vitamin C, 50mcg of B12 and 330mcg of biotin, plus five bacterial strains. It prints that panel per 100g and per serving, which not every brand does. Good Housekeeping's panel even liked the taste.

Two things AG1 does not have: collagen and creatine. Neither is in its ingredient list. Hold that thought.

What to look for in an AG1 alternative

Most "AG1 alternatives" lists pretend one product wins. None does. Three different jobs hide inside that one search. Work out which is yours first.

• The same thing, cheaper. You liked the all-in-one idea. You just will not pay £2.63 a day for it.
• Only ever vegetables in a glass. You already take a multivitamin. You want the veg you keep not eating.
• You felt nothing. You finished a whole tub. You honestly could not say it did anything.

A different product wins each job. Only the third is ours, and we come last.

One more thing to check: the units. Some brands print the panel per 100g when the serving is 5g. Rheal's Clean Greens panel is headed "Total per 100g". It lists 455mg of vitamin C at 569% NRV. But one serving is 5g. So a serving gives about 22.8mg, or roughly 28% NRV. That is 20 times smaller than the headline. Nobody is hiding anything. You just have to do the maths.

The six best AG1 alternatives in the UK

All prices were checked in August 2026 on each brand's own UK site. Price per day uses the best standard subscription price where there is one. Otherwise it is the pack price divided by servings. Delivery is excluded, except in our own row, which shows the figure both ways.

1. Huel Daily Greens — the same idea for less

£45 on subscription, £50 one-off. 30 servings of 8.5g. £1.50 a day. The straight swap: 91 vitamins, minerals, greens and adaptogens, plus two bacterial strains.

Wins on: people actually drink it. Testers found it "significantly nicer than other greens powders they've tried, so they felt motivated to keep using it". Highest fibre in that test, at 3.5g. And by our maths it is 43% cheaper per day than AG1. AG1 goes further. Its own comparison page puts Huel at half AG1's price per serving. That table is scored by AG1 itself.

Loses on: "excessive servings of some nutrients", said the same nutritionists. There is a little sucralose in the blend. No clinical trial on the finished formula, and two bacterial strains to AG1's five.

Buy it if: you are leaving AG1 on price, and you need a powder that tastes like a drink.

2. Bulk Complete Greens — the cheapest greens in a glass

£26.99 for 500g. 55 servings of 9g. £0.49 a day. The 100g tub is £6.99, the 1kg £49.99. Bulk was running a summer promotion when we checked, so the RRPs are higher.

Eight greens and nothing else in the unflavoured version. Spirulina, chlorella, broccoli, pumpkin seed protein, spinach, alfalfa, moringa and kale. That is the whole label.

Wins on: price, by a distance. Roughly a fifth of AG1 per day. The nutritionists rated it "up there with the most natural options in this round-up".

Loses on: everything else. No vitamins, no minerals, no probiotics, no actives. The same test marked it down because "NRVs not provided and lack of clarity around ingredient quantities". Taste split the panel: "too musty and difficult to drink" for some, "too sweet" for others. It may contain milk, soya, gluten, mustard, sesame and sulphites.

Buy it if: you have decided a greens powder is a vegetable top-up and nothing more.

3. Rheal Clean Greens — the cleanest short label

£20 on subscription, £25 one-off. 30 servings of 5g. £0.67 a day. Eight certified organic ingredients and nothing else: baobab, barley grass, wheatgrass, moringa, freeze-dried pineapple, chlorella, spirulina and acerola.

Wins on: label. Good Housekeeping's nutritionist called it a "very clean formula" with "no additives". The pineapple version scored well on taste. At £0.67 a day it costs a quarter of AG1.

Loses on: dose. A 5g serving is small, and the panel is per 100g. Most testers "only noticed a slight increase in energy levels". Rheal's own answer to that is to give it six months.

Buy it if: you want a simple organic top-up and are not expecting to feel anything dramatic.

4. Free Soul Greens — the best-liked budget option

£25.99 on subscription, £32.49 one-off. 30 servings of 5g. £0.87 a day. 21 greens and superfoods, formulated for women. KSM-66 ashwagandha, maca, Actazin and Livaux kiwi, spirulina, chlorella, alfalfa and wheatgrass. There is 30mg of green tea extract a serving, which is 2.1mg of caffeine.

Wins on: the independent score. It got 93 out of 100 at Good Housekeeping. That ties AG1, at a third of the price. NRVs are balanced, from 12% to 217%.

Loses on: mixing. The "powder requires a good stir to dissolve fully". The experts also warned that ashwagandha, moringa leaf, alfalfa and lucuma "can cause GI issues if taken in large quantities". And 5g is a modest dose of anything.

Buy it if: you want greens plus digestion support for under £1 a day, in a fruit-flavoured drink.

5. JSHealth Greens + Collagen — greens with a nod to collagen

£37.99 one-off, £32.29 on subscription. 30 servings of 6.5g. £1.27 a day, or £1.08 on subscription. Broccoli, spinach, kale, barley grass and wheatgrass, plus inulin and 1g of hydrolysed marine collagen a serving.

Wins on: taste, over us. "It tastes amazing," said one at-home tester. The food team called it "mild and well balanced", and it "dissolved quickly in water and juice, with no grainy residue". Marine collagen also suits people who will not take bovine.

Loses on: the collagen dose. Clinical work on skin and joint outcomes usually uses 2.5g to 10g a day. So 1g is a positioning dose, not a working one. There is no creatine either.

Buy it if: you want a pleasant greens drink with a little collagen, and you avoid bovine sources.

6. Myprotein THE Performance Superfoods — greens with real creatine

£27.49 for 425g. 24 servings of 17.7g. £1.15 a day. A 23% greens blend, plus Creapure® creatine monohydrate, L-glutamine, betaine, lion's mane, cordyceps, ashwagandha and electrolytes. The brand's own FAQ states 3.4g of Creapure® a scoop.

Wins on: actives. This is a real greens-and-creatine product on a UK shelf at £1.15 a day. It answers "greens powders never contain anything that does anything" head on. It also means we cannot say we are the only greens powder with creatine in it. So we will not.

Loses on: the greens. They are 23% of the formula and the individual doses are not broken out. It is built for training, not for a morning habit. Read the label carefully too. The nutrition table is printed per 35.4g, which is two scoops.

Buy it if: you train hard and want creatine and greens in the same tub.

One alternative that is not cheaper: IM8

IM8 Daily Ultimate Essentials Pro is £89 per four weeks. That is £2.97 a day, more than AG1. The 12-week plan costs £235 and brings it to £2.61. It publishes a milligram figure for nearly every active, it is NSF Certified for Sport, and it ran a 12-week randomised trial. By AG1's own table it has one trial to AG1's four. Buy it if: you are leaving AG1, but not over money.

Price per day, side by side

Prices and formulas checked August 2026 from each brand's UK site. The last column is company base, not factory address. Only two manufacturing locations here can be verified: Collagen Greens is made in the UK, and AG1 is not. Brands change their formulas from time to time, so check the label before you buy.

The arithmetic behind that first column is set out in our guide to greens powder cost per day in the UK. If you only want the one head-to-head, our Collagen Greens vs AG1 comparison goes line by line.

Where Collagen Greens honestly sits

Sixth of nine on price. Five of the seven alternatives above cost less per day than we do. We are mid-priced, not cheap, and we will not pretend otherwise.

Here is what we do not have. No clinical trial on the finished formula; AG1 has four. No Informed Sport or NSF certification; AG1 and IM8 have those. We do not publish a vitamin panel to match AG1, IM8 or Huel, and we will not imply one. Our greens are modestly dosed. If your job is "cover my multivitamin", buy one of those three instead.

Our powder is unflavoured and earthy. It tastes like real greens, because that is what it is. No added sugar, no artificial sweeteners, just a whisper of stevia leaf. Huel, Free Soul, Rheal and JSHealth all scored well on flavour in that independent test. We would not. It may also contain wheat, barley, celery and gluten, so coeliacs should choose a certified brand.

Now the one thing that is ours. One 12.6g scoop holds 4g of creatine monohydrate and 4g of bovine collagen peptides, Type I and III. That is 63% of the scoop by weight. Myprotein has creatine but no collagen. JSHealth has 1g of collagen, a quarter of our dose, and no creatine. We checked every product here, plus all 13 in the Good Housekeeping round-up. We found nothing else pairing a clinically used creatine dose with a clinically used collagen dose.

That is also where the price argument turns. Bought as three separate tubs, greens plus collagen plus creatine runs past £80 a month. Here it is one scoop and one subscription.

That is the answer to the third job. Most greens powders have no energy actives in them at all. You feel nothing because there is nothing in the tub to feel. We explain that failure mode in do greens powders work. Creatine is different. It builds up over about a fortnight, so give it two to three weeks.

The price, in full. Collagen Greens is £38.50 for your first month on Subscribe & Save, then £44 a month. That is £1.33 a day. Delivery is £3.50 on subscription, so a first order comes to £42.00 and the honest daily figure is £1.44. One pack alone is £55 plus £4.99 delivery. Against AG1's £2.63 a day, that is roughly half, with two actives AG1 does not carry.

"Changed over to the new Collagen Lean Greens and wow, what a difference. Energy levels picked up straight away. Was sceptical at first but well worth the change." — Paulo, Darlington

There is a 60-day money-back guarantee behind it. Full refund on your first order, up to one whole opened bag. AG1 gives you 30 days.

AG1 alternatives: your questions

What is the cheapest AG1 alternative in the UK?

Bulk Complete Greens, at £0.49 a day. That is the 500g tub at £26.99, which is 55 servings of 9g. Roughly a fifth of AG1 per day. You get eight greens and nothing else. No vitamins, no minerals, no probiotics. Rheal Clean Greens is next at £0.67 a day if you want organic.

Is there an AG1 alternative with collagen or creatine in it?

Yes, but read the doses. Myprotein THE Performance Superfoods has 3.4g of Creapure® creatine a scoop, at £1.15 a day. JSHealth Greens + Collagen has 1g of marine collagen, at £1.27 a day, or £1.08 on subscription. AG1 itself has neither. Collagen Greens has 4g of each in one 12.6g scoop. We found no other UK product pairing both at those doses.

Will I lose AG1's vitamin coverage if I switch?

It depends where you go. Huel and IM8 both run broad vitamin panels. Bulk, Rheal and Free Soul do not, and nor do we. So if AG1 is your multivitamin, replace it with something that publishes NRVs. Check the panel is printed per serving, not per 100g.

How long before a greens powder does anything?

A plain greens powder may never give you something you can point at. It is nutritional cover, not a lift. Where there is creatine, the honest answer is two to three weeks, because creatine builds up over roughly a fortnight. Judge any powder on a month, not a week.
