What is Spirulina Powder?
Spirulina powder is a vibrant green superfood. It is a blue-green algae that grows naturally in highly alkaline water. This natural supplement has been used for centuries by various cultures, most notably by the Aztecs, who valued it for its potent nutritional content and ability to sustain energy.
Spirulina is now cultivated worldwide, including in environmentally controlled farms in Australia. Available in powder, tablet, and capsule forms, the powder is especially popular due to its versatility in recipes and ease of absorption.

Boosts Immune System
Spirulina powder enhances the body’s natural defences by increasing the production of white blood cells and antibodies. Its antioxidant content helps ward off infections and chronic inflammation, supporting overall immunity.
Enhances Energy Levels

Supports Heart Health
Spirulina has been shown to lower bad LDL cholesterol and triglycerides while raising good HDL cholesterol. It also helps manage blood pressure, reducing the risk of cardiovascular diseases.
Aids in Detoxification
Chlorophyll in Spirulina binds with heavy metals and toxins, helping the body naturally flush them out. This makes it a popular choice in detox regimens.
