Multiple independent sources (a PMC/NIH review, a 2026 Foods review, Harvard Health, and MSKCC) state that spirulina contains gamma-linolenic acid, and the claim faithfully matches the passage's wording. The claimant's own words are not used as evidence.

What was said

… You can't have it exposed to air, so you have to take it as a gel cap. But if you learn about these substances oh, and I forgot to mention, spirulina also contains gamma linolenic acid, which is a very potent nutritive support to support your body's natural normal response to inflammation, for example, and other benefits.

What we found

Supports. A primary NIH/PMC review states spirulina contains health-promoting fatty acids such as gamma-linolenic acid (GLA).[1]

Supports. A 2026-published primary review in Foods describes GLA as the most prominent fatty acid in spirulina, typically 1-2% of dry weight.[2]

Supports. Harvard Health states spirulina is a good source of gamma linolenic acid, and MSKCC states spirulina contains high levels of GLA.[3][4]

Context. Sources vary on quantity (GLA share of fatty acids ranges from 10-20% in one species to 49% in another), but this does not affect the core assertion that spirulina contains GLA.[5][6]
