Frequently asked questions
- What is AG1?
- A multi-ingredient daily greens powder — combines greens (spirulina, chlorella, grasses), vitamins, minerals, probiotics, prebiotics and adaptogens in a single daily scoop. Marketed as a 'one supplement' solution.
- Why is it so expensive?
- AG1 sits at the premium end of the greens-powder market at around £97 for a 1-month supply. Cheaper alternatives (like Nuzest Good Green Vitality at £75) cover much of the same category — whether the brand premium is worth it depends on how much you value the brand's testing programme and ingredient list.
- Is NSF Certified for Sport meaningful on a greens powder?
- Yes — multi-ingredient greens powders are a category where contamination risk is elevated due to the long ingredient list. NSF tests each batch against 280+ banned substances.
- Is it a meal replacement?
- No — AG1 is a supplement powder, not a complete nutrition replacement. Mix with water; it's not designed to substitute meals.
- How does it compare to Nuzest Good Green Vitality?
- Both are multi-ingredient daily greens powders with Informed Sport / NSF certs (AG1 = NSF, Nuzest = Informed Sport). Nuzest is the cheaper option (£75 vs £97). Ingredient lists differ; compare the published labels before deciding.
