United States: GRAS status
In the US, spirulina is classified as GRAS — Generally Recognised As Safe — by the FDA. This classification means spirulina is considered safe for use as a food ingredient based on scientific evidence and common usage. GRAS status allows spirulina to be sold as a food supplement without pre-market approval.
GRAS does not mean the FDA has tested or approved spirulina supplements individually. It means the ingredient category is on the FDA’s list of substances considered safe for the general population. Individual products are regulated under DSHEA (Dietary Supplement Health and Education Act), which requires manufacturers to ensure safety but does not require pre-market proof of efficacy.
Practical implication: US spirulina products must meet food safety standards (GMP — Good Manufacturing Practice) but are not required to prove their health claims before selling. This is why US supplement marketing can make more adventurous claims than EU marketing.
European Union: Novel Food history and current status
The EU’s regulatory history with spirulina is more complex. Spirulina is a traditional food in some non-EU countries (Mexico, Chad) and has been sold in the EU since before the Novel Food Regulation came into force in 1997.
Spirulina has been determined to have a “significant history of consumption” in the EU prior to 1997, meaning it does not require Novel Food authorisation. It can be sold in EU member states as a food supplement.
However, the EU’s health claims regime (Regulation (EC) No 1924/2006) is strict. Health claims made about spirulina products in the EU must be on the approved list (the EU Register of Authorised Claims) or meet the “authorised only if” conditions. Most spirulina-specific health claims (beyond generic nutrient content claims) have not been authorised.
What EU producers can claim: the nutrient content of their product (e.g., “source of iron”, “contains protein”) if the product meets the nutritional threshold. They cannot legally claim spirulina “supports immune health” or “reduces cholesterol” in EU marketing without specific authorisation.
United Kingdom: Post-Brexit alignment
The UK retained its own Novel Food Register and health claims regime post-Brexit, broadly aligned with EU standards at the point of exit. Spirulina’s traditional food status is similarly recognised. UK health claims regulation (enforced by the Food Standards Agency) is similarly restrictive to EU claims regulation.
Japan: Functional food recognition
Japan has a sophisticated functional food regulatory system — FOSHU (Foods for Specified Health Uses) and FFC (Foods with Functional Claims). Spirulina has been consumed as a health food in Japan since the 1970s and several Japanese products have FFC designation with specific function claims related to cholesterol or antioxidant status. The DIC Lifetec operation in Japan has operated under this framework for decades.
Turkey: Supplement regulation under TGDF
Turkey regulates food supplements under the Türk Gıda Dergisi Fonksiyonel system, with oversight from the Turkish Food and Drug Administration (TITCK). Spirulina is classified as a food supplement and can be sold legally. Health claims are subject to regulation; Turkish marketing tends to be less restricted in practice than EU marketing but is theoretically subject to similar claim requirements. Turkish producers selling to EU markets must comply with EU regulations on export products.
What regulatory status means for buyers
Understanding regulatory context helps interpret product marketing:
- EU products with strong, specific health claims — these claims are not EU-authorised for spirulina specifically. Treat them with appropriate scepticism.
- US products with disease-related claims— also not FDA-approved for spirulina. DSHEA requires a disclaimer (“This statement has not been evaluated by the FDA”) on all structure-function claims.
- Organic certification — regulated in both US and EU, meaning the certification body has verified the production claims. This is one marketing claim with genuine regulatory teeth.
The quality gap that regulation doesn’t cover
Neither GRAS status nor EU Novel Food non-applicability addresses the quality concerns that matter most for spirulina: heavy metal contamination, microcystin content, and phycocyanin content. These require producer-specific voluntary testing and transparency — which is why the CoA remains the primary quality signal regardless of market.
