Collagen Greens vs AG1 (Athletic Greens)
Tim GoodwinBoth products promise a daily nutrition shortcut. We compared ingredients, price, formulation focus, and overall value to see which one makes more sense for real life.
Greens powders have exploded in popularity over the past few years. Walk into any health food shop or scroll through Instagram, and you'll see dozens of options promising to transform your morning routine.
Athletic Greens (AG1) has become one of the most recognisable names in this space. Heavy investment in podcast sponsorships, influencer partnerships, and premium branding has made it the default choice for many health-conscious consumers.
But with that recognition comes a premium price tag — roughly £97 per month for UK customers (£79 per month on subscription).
Newer alternatives have emerged that take a different approach. Rather than trying to be everything to everyone, they focus on specific gaps that most adults actually have: protein intake, collagen for skin and joints, and energy support.
Collagen Greens by Lean Greens is one of those alternatives. This page compares both products side-by-side — price, ingredients, formulation philosophy — so you can decide which makes more sense for your routine.

The Real Price of Your Daily Habit

Complexity vs Consistency
Here's something most supplement companies won't tell you: the best product is the one you actually use. Many people buy premium supplements with the best intentions, then quietly stop using them after a few weeks.
The reasons vary — taste, routine friction, complexity, or simply forgetting.
A simpler product taken daily will always outperform a complex product sitting in your cupboard.
Collagen Greens was designed with this in mind. Neutral taste. Easy mixing. No elaborate protocols. Just a 30-second morning habit that fits into your existing routine.
AG1 is by no means a bad product — it's comprehensive and well-formulated. But for many people, that comprehensiveness comes with a complexity they don't need. Sometimes, less really is more.
Deep Dive Into Collagen Greens
The original Lean Greens super greens powder formulation was originally developed back in 2012. The core components of that formulation remain largely untouched as it was so far ahead of its time.
Super Greens Blend
Instead of stacking dozens of synthetic ingredients, Lean Greens contains a few raw, freeze-dried-dehydrated vegetables and greens ingredients designed to maximise bio-availability and stick to it's roots as an alternative to vegetable juicing.
Digestive Enzymes
Digestive enzymes are a core part of many foods we simply don't eat in our modern diets. When was the last time you had pineapple (that wasn't on a pizza)? These enzymes are vital to help the body digest unprocessed foods, such as Lipase to help process fats, or protease for breaking down proteins.
Collagen Greens utilises the 6 core digestive enzymes your body needs to help your body every day.
Hydrolysed Collagen
Collagen is a much disputed dietary supplement ingredient. What we do know is that the healthier the body, the more collagen is produced naturally by the body, and the more additional collagen consumed can help provide the outcomes people expect from collagen.
So combining hydrolysed Bovine Collagen with the Lean Greens formulation was a no brainer, as they work hand in hand to help you be a healthy collagen-forming body!
Creatine Monohydrate
Finally the crowning ingredient in Collagen Greens is creatine monohydrate. It is a much studied ingredient in body-building circles, however more research is pointing to the positive benefits for people of all ages and activity levels.
Including this alongside collagen makes Collagen Greens the most complete and unique super greens formulation available today. And with it being half the price per serving of AG1, the choice is clear which product should be considered.

- You're comfortable paying premium pricing for a formulation with 75+ ingredients in 13g serving

Collagen Greens is right for you if...

- You specifically want collagen and creatine in your routine
- You want better value without a lifestyle overhaul
- You want practical, not extreme. Something that works and you can feel it!

Ingredient-by-Ingredient
The headline difference isn't the greens — both contain a comparable greens base. It's what sits alongside them. AG1 spreads across 75+ ingredients including adaptogens and mushrooms; Collagen Greens concentrates on two clinically dosed actives most UK adults are short of.

The honest case for AG1
AG1 is a well-made product and there are genuine reasons to prefer it. If you specifically want adaptogens, mushroom extracts, and the broadest possible vitamin and mineral coverage in a single scoop, AG1 covers more ground than Collagen Greens does. Its 90-day guarantee is longer than our 60-day one. And if you already take a separate collagen and creatine supplement you're happy with, the case for switching is much weaker.
Where Collagen Greens wins is on cost per serving, on including 4g each of collagen and creatine that AG1 doesn't have at all, and on being made in the UK with UK-based support. Which of those matters more depends entirely on what you're buying a greens powder for.
Delivery and support in the UK
Collagen Greens ships from our UK warehouse. Order before 2pm on a weekday and it goes out the same day, arriving in 2–3 working days on Royal Mail 48, or next working day via DPD. Support is answered by the same UK team — the founders reply to reviews by name.
