Arthrospira platensis
Blue-green microalgae, concentrated source of protein and iron.
Spirulina is a cyanobacterium (microalgae) cultivated for centuries by the Aztecs and Lake Chad populations. Composed of 60-70% protein, rich in iron, phycocyanin (blue antioxidant pigment), beta-carotene and B vitamins, it is one of the most studied dietary supplements in the world.
Spirulina (Arthrospira platensis) is presented here as an educational botanical remedy profile: what people traditionally use it for, how it is commonly prepared, and where the safety boundaries are.
Spirulina is a cyanobacterium (microalgae) cultivated for centuries by the Aztecs and Lake Chad populations. The important nuance is that the form matters: tea, powder, tincture, capsule and essential oil can produce different exposure levels and different risks.
Use this page as a practical starting point for steady energy and fatigue-aware routines, not as a diagnosis or treatment plan. The safest approach is to compare the expected benefit, the preparation, the dose context and your personal health situation before deciding whether the plant belongs in your routine.

The evidence picture for Spirulina depends heavily on the plant part, preparation and dose. Traditional use is a useful signal, but it is not the same as proof for every modern health claim.
The strongest claims on this page are kept practical and cautious: Rich in protein, Anti-anemic, Antioxidant, Detoxifying, Immune stimulant. They should be read as areas of traditional or researched interest, not guaranteed outcomes.

| Decision point | What to check |
|---|---|
| Common forms | As powder, tablets, flakes or added to smoothies and juices. |
| Preparation baseline | Start with 1g/day and gradually increase to 3-5g/day. Mix in fruit juice or smoothie. Avoid heating. |
| Best-fit context | steady energy and fatigue-aware routines; seasonal immune support; liver, kidney and elimination support |
| When to pause | Choose quality-controlled spirulina (risk of heavy metal contamination). |
| Quality marker | Prefer products that state the plant part used and the extract ratio or preparation method. |
Compare Spirulina with plants that share the same goal, then choose based on preparation, safety profile and your context. A gentle tea, a standardized extract and an essential oil should never be treated as the same intervention.
