Yes, spirulina can be evaluated in a protein-bar formula, but the important question is how the complete bar performs. A promising small sample still needs checks for binding, bite, flavour, moisture and storage stability. Do not assume the ingredient’s protein percentage transfers directly into a finished bar’s nutrition claim; verify the finished product.

What research can tell you
A 2025 study explored a brown-rice protein bar formulated with Spirulina platensis and phycocyanin. It evaluated formulation and quality using methods including FTIR and multivariate assessment. This is evidence that the application is being studied, not proof that one formula works across bar types, equipment or ingredient suppliers.

Start with a clear control
Make a base bar without spirulina, then compare a small number of planned variants. Keep the binder, sweetener, oil, protein base and mixing sequence consistent. Record the spirulina lot and addition point. If you test green biomass and blue phycocyanin, treat them as separate ingredients and trials.
A powder can change colour and the way a mixture feels before forming. Watch for dry pockets, uneven colour and crumbling when cut. Check whether its flavour competes with cocoa, fruit, nuts or other ingredients.
Build a simple measurement sheet
Record mixture handling, formed dimensions, cutting performance, hardness, moisture or water activity using a suitable method, flavour, aroma, aftertaste and changes over the intended shelf-life. Use coded samples and ask panelists to rate attributes separately; “Do you like it?” alone will not explain a failure.
Don’t copy another study’s percentages
Published studies use different protein bases, binders, oils, moisture levels and processes. A result from a brown-rice bar does not set a recommended use level for another bar or AimGrow material. Choose levels from your brief and supplier documentation, then test on your own line.
Before a production run, confirm the ingredient specification, lot documents and storage requirements. AimGrow lists a bulk spirulina powder product; ask the company for current details and available formats. Your pilot must validate the finished bar.
The cited 2025 study concerns a specific brown-rice bar with Spirulina and phycocyanin. It is not a universal recipe or a product claim.
