About
What it is and where it shows up.
Spinach powder is produced by dehydrating and milling the leaves of Spinacia oleracea; it is used in food products, dietary supplements, and nutraceuticals to deliver nutrients (vitamins A, C, K, folate, iron), natural green pigmentation, and mild vegetable flavor.
Safety summary
The regulatory and scientific consensus.
Spinach powder is generally safe for healthy adults and is not classified as a regulated food additive in any major jurisdiction, carrying no specific ADI. It is naturally high in oxalates, which can promote calcium oxalate kidney stone formation in susceptible individuals, and rich in vitamin K, which may antagonize anticoagulant medications such as warfarin. Concentrated forms may contain significant levels of dietary nitrates, raising particular caution for use in infant foods due to the risk of methemoglobinemia.
Regulatory landscape
What food-safety regulators have decided.
| Jurisdiction | Status | Note |
|---|---|---|
| FSANZ (Food Standards Australia New Zealand) (Australia) | Approved | Spinach powder is classified as a standard food ingredient (dehydrated vegetable) under the Australia New Zealand Food Standards Code and is not subject to food additive scheduling. No specific maximum intake level is specified.source |
| EFSA (European Food Safety Authority) (European Union) | Approved | Spinach powder used as a food ingredient is not a food additive under Regulation (EC) No 1333/2008 and requires no E-number; it is permitted as a conventional foodstuff under Regulation (EC) No 178/2002. When used specifically as a natural colorant, chlorophyll extracts (E 140) derived from spinach are separately regulated under the EU positive list for food colours.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Spinach (Spinacia oleracea) is a recognised vegetable under the Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011; spinach powder as a dehydrated vegetable product is permitted for use in food and nutraceutical products without a specific usage cap. Health benefit claims on nutraceutical products containing spinach powder require prior FSSAI approval per FSS (Health Supplements, Nutraceuticals) Regulations, 2016.source |
| FDA (Food and Drug Administration) (United States) | Approved | Spinach powder is a dehydrated whole-vegetable ingredient and is not subject to food additive pre-market approval under 21 CFR; it is regarded as GRAS (generally recognized as safe) by virtue of its status as a conventional food. No specific maximum use level is codified in 21 CFR Parts 182 or 184. |
Who should approach with care
Whose guidance would steer them away.
Kidney Disease — Spinach powder is naturally high in oxalates; regular consumption can increase urinary oxalate excretion and promote calcium oxalate kidney stone formation, which is particularly harmful in individuals with chronic kidney disease or a history of oxalate nephrolithiasis.
Infants — EFSA has identified spinach and other leafy greens as major dietary nitrate sources; concentrated spinach powder poses a risk of methemoglobinemia (blue-baby syndrome) in infants due to their limited capacity to reduce nitrite formed from nitrates.
Other — Individuals on anticoagulant therapy (e.g., warfarin) should consult a physician before regularly consuming spinach powder, as its high vitamin K content can antagonize anticoagulant efficacy and cause clinically significant fluctuations in INR levels.
Gout — Spinach contains purines; while not among the highest dietary purine sources, concentrated spinach powder may contribute to elevated serum uric acid levels in gout-prone individuals and potentially trigger flare-ups.
