What it is
A mix of powdered greens — spirulina, chlorella, wheatgrass, spinach, broccoli and similar — dried and concentrated. Marketed as covering your vegetable bases.
Why people take it
The individual components contain real nutrients and some (spirulina) have small human trials on lipids and inflammation. But the blend as a product has essentially no outcome trials, and one scoop delivers far less than the vegetable portioner it is compared to in marketing.
Our verdict
A reasonable top-up, a poor substitute. Pay attention to whether the label tells you what is actually in it.
Structure & class
Dehydrated concentrate of green vegetables, grasses and algae. Micronutrient content depends entirely on composition, which is usually proprietary.
Mechanism & clinical data
Component-level data exists (spirulina meta-analyses on lipids, chlorella trials on blood pressure) at gram-level doses. Greens blends typically deliver components in sub-gram amounts. Product-level RCTs (AG1 2025) establish safety and microbiome shifts but not clinical outcomes. No greens blend has a published RCT showing improvement in a hard health endpoint.
Pharmacokinetics
Varies by constituent.
Dose & forms
What to watch out for
Marketing compares one scoop to '5 portioner of vegetables' — the fiber, volume, and satiety of actual vegetables are not in the scoop. Heavy-metal testing matters for algae components.
Where this dose comes from
The trial dose above is our editorial pick from the published human trials for this ingredient. We choose the dose that the best-available studies used on the endpoint most relevant to longevity. The range shows the lowest and highest doses tested in published trials. The landmark studies below are the papers we read to set it. You can click through and check our work.
When new trials publish, our automated sweeps flag them. If a new study materially changes the dose, we update it through editorial review and record the old dose, new dose, and the triggering study in every affected product's recommendation history. The dose is never changed automatically.

EU report identifies 117 supplement substances as potential health risksThe HoA Working Group on Food Supplements (26 European countries) published its first report evaluating 117 substances used in food supplements. Of these, 65 were assessed as likely novel foods, 6 were already regulated, 34 had insufficient data, and 12 were prioritized for Article 8 restriction under Regulation (EC) No 1925/2006. The 12 priority substances include ashwagandha, curcumin, melatonin, piperine, St. John's wort, coumarin, p-synephrine, maca, holy basil, Melaleuca, black cohosh, and L-tryptophan. The report drew on 1,500 RASFF alerts reviewed between 2017 and mid-2022.

EU Health Claims Regulation adoptedRegulation (EC) No 1924/2006 laid down harmonised rules for nutrition and health claims made on foods, including supplements. Only claims listed in the EU Register of authorised claims can be used. Rejected botanical claims are held in a separate on-hold list.

EU introduces the Novel Food RegulationRegulation (EC) No 258/97 required any food or food ingredient without a history of consumption in the EU before 15 maj 1997 to be authorised before being placed on the market. This is the framework that captures NMN, spermidine as a supplement ingredient, urolithin A, and many other longevity actives.
