Bio PetActive Spirulina is a natural whole-food supplement for birds — a fine powder of the blue-green microalga spirulina, one of the richest natural sources of protein and micronutrients there is. Where a vitamin drop tops up a few specific nutrients, spirulina brings a broad, food-based boost in one ingredient.

A whole food, not just a vitamin

Spirulina is a completely natural food, and its appeal is how much it carries in one ingredient. At around 60% protein it's one of the best plant protein sources available, and it's a complete protein — it contains all the essential amino acids a bird needs, not just some of them. On top of that it supplies beta-carotene, vitamin B12, the B-complex, iron, other essential minerals, and gamma-linolenic acid, an important fatty acid.

It's also easy for a bird to digest. Spirulina's cell wall is made of soft mucopolysaccharides rather than cellulose, so there's no tough plant fibre to break down — the nutrients are readily available. The visible payoff shows up where you'd expect from a protein-and-carotene-rich food: healthier, brighter, shinier feathers, and support for a healthy gut flora.

• ✓60% complete protein. All the essential amino acids from one natural source.
• ✓Rich in micronutrients. Beta-carotene, B12, B-complex, iron, minerals and gamma-linolenic acid.
• ✓Easily digestible. No cellulose in the cell wall, so nutrients are readily absorbed.
• ✓Feather & gut support. For healthy, shiny plumage and a healthy intestinal flora.

How it differs from a vitamin drop

A multivitamin corrects specific gaps in a seed diet; spirulina works more like an upgrade to the diet itself — a concentrated natural food that adds protein, colour-supporting pigments and a broad micronutrient base. It's a natural fit during moulting and breeding, when protein demand is highest, and for softbills and other species that benefit from a richer nutritional base. Many keepers use it alongside a vitamin supplement rather than instead of one, since the two do different jobs.
