Spirulina: The Complete Superfood Guide

Spirulina is a blue-green algae that grows naturally in both fresh and salt water. It is widely regarded as one of the most nutrient-dense foods on the planet — gram for gram, few natural foods can match its nutritional profile.

The Nutritional Profile A single tablespoon of spirulina contains approximately 4 grams of protein, alongside significant amounts of B vitamins, iron, copper, magnesium, and antioxidants including phycocyanin — the compound responsible for its distinctive blue-green colour.

Potential Benefits

• Exceptionally rich source of plant-based protein

• Contains iron which contributes to normal energy metabolism

• Rich in antioxidants that help protect cells from oxidative stress

• May support healthy immune function

• Naturally rich in B vitamins including B12 precursors

How to Take It Spirulina is available in tablet and powder form. Tablets are the most convenient option for daily supplementation. The powder can be added to smoothies, juices, or water — though its strong flavour means most beginners prefer to start with tablets. A typical daily dose is 3–5 grams.

What to Look for When Buying Choose organic spirulina from a reputable source to ensure it is free from heavy metals and contaminants. Look for products that are third-party tested and clearly state the country of origin.
