We tested AG1, Huel Daily Greens, Rheal, Free Soul, and Lean Greens Collagen Greens. Here's the honest breakdown — ingredients, value, taste, and who each one is actually for.
For most UK adults in 2026, Lean Greens Collagen Greens is the best overall greens powder — combining 18 whole-food green ingredients with 4g of hydrolysed collagen and 4g of creatine monohydrate in a single 30-second drink. It costs approximately £1.50/serving on subscription, ships next day across the UK, and comes with a 60-day money-back guarantee. For those wanting maximum ingredient breadth and elite testing standards, AG1 Next Gen remains the premium benchmark at £2.63–£3.23/serving. Huel Daily Greens is the best budget option at ~£1.35–£1.50/serving. None of the others offer collagen or creatine. Before choosing: no greens powder replaces whole vegetables, but for the 83% of UK adults failing to hit 5-a-day, a daily greens drink is a realistic and cost-effective nutritional top-up.
Ranked on: ingredient quality, price per serving, taste, transparency, and standout differentiation for UK consumers.
The only UK greens powder combining 18 whole-food green ingredients with 4g hydrolysed collagen and 4g creatine monohydrate per serving. Made in the UK since 2012. Replaces three separate supplements at roughly half the price of AG1. Neutral taste, mixes in 30 seconds, 60-day refund guarantee. Best for: UK adults who want greens, collagen, and creatine in one drink.
83 ingredients, NSF Certified for Sport, Informed Choice approved, extensive third-party testing. The most comprehensively tested greens powder available. Updated in 2025 with new probiotic strains and added micronutrients. At £79–£97/month it's the most expensive option by a significant margin — and doesn't include collagen or creatine. Best for: those prioritising third-party certification above all else, budget permitting.
91 ingredients including vitamins D and K (which AG1 lacks), plus iron, iodine, and adaptogens. Strong value at ~£1.35/serving on subscription. Some reviewers note a slightly chalky texture and stevia aftertaste. No collagen, no creatine, and probiotic content is low (3mg). Best for: those wanting maximum ingredient count at an accessible price point.
A deliberately minimal formula — just 6 core ingredients including spirulina, chlorella, wheatgrass, and matcha. No fillers, no sweeteners, no adaptogens. Excellent for people who want the simplest possible greens supplement. Pricier per serving for what you get. Best for: those who want ultra-clean, minimal-ingredient greens.
A women-focused greens powder with a pleasant taste profile and solid brand positioning. Good social proof and aesthetically designed packaging. Ingredient depth is limited compared to the above options and price-per-serving is less competitive. Best for: those drawn to the brand's community and aesthetic, particularly younger women.

Before spending money on any greens powder, these are the four things worth checking.
Pure greens top-up? Any quality powder will do. Want collagen for skin and joints? Only Lean Greens Collagen Greens includes it. Training and want creatine? Same answer.
Headline prices are misleading — always divide by number of servings. £97 for 30 servings (AG1) is very different to £45 for 33 servings (Lean Greens). Subscription discounts add up over a year.
A product listing 91 ingredients doesn't mean effective doses of each. Proprietary blends hide how much of each ingredient you're actually getting. Transparent labelling matters.
The best greens powder is the one you actually drink daily. Look for brands with money-back guarantees so you can test taste risk-free. Neutral or mild flavours tend to have better long-term compliance.
If you're already taking a collagen supplement and creatine separately, switching to Lean Greens Collagen Greens can simplify your routine and reduce total cost significantly.
Greens, collagen, and creatine in one 30-second drink. Made in the UK since 2012.
60-day money-back guarantee — return even an empty tub for a full refund.
