Learn all about Spirulina
What is Spirulina?
Energise with nature's multivitamin - spirulina. This complete protein source contains rare phytonutrients for total body wellness. Feel vibrant!
Benefits of Spirulina
"Spirulina represents one of nature's most nutritionally complete food sources. What makes it particularly remarkable is not just its protein density, but its exceptional micronutrient profile, including rare compounds like phycocyanin that aren't readily available in conventional foods. Its sustainability profile - requiring minimal land, producing protein efficiently, and even absorbing carbon dioxide - makes it increasingly relevant as we face global nutrition and environmental challenges."

How to use Spirulina
Dosage
3-5g daily for general health; 5-10g daily for specific health concerns
Timing
Can be taken with or between meals; dividing into multiple doses throughout the day may enhance tolerability
Notes
Start with lower doses (1g) and gradually increase to assess tolerance; consuming with sufficient water helps prevent digestive discomfort
Who should take Spirulina?
- Individuals seeking plant-based protein supplementation
- Those with increased nutrient needs or limited dietary variety
- People looking to support immune system function
- Athletes and active individuals interested in recovery and performance
- Those exposed to environmental toxins or pollutants
- Individuals interested in supporting healthy ageing through antioxidant intake
How does Spirulina work?
Spirulina's diverse biological effects stem from its rich nutrient profile and bioactive compounds. Its phycocyanin content helps reduce inflammation signals and cell damage. Complete protein content supports tissue maintenance and immune function. The high chlorophyll content assists in detoxification processes by binding to toxins in the digestive tract. Additional mechanisms include influencing gut bacteria balance, boosting nitric oxide to help blood vessels relax, and providing key nutrients for how cells work.
Frequently asked questions
Natural sources of Spirulina
Spirulina grows naturally in warm, alkaline freshwater lakes with high pH and salt content, particularly in subtropical and tropical regions including Mexico, Central Africa, and certain areas around the Great Lakes. Commercial spirulina is typically cultivated in controlled pond systems or photobioreactors (closed systems for growing algae). As a specific type of cyanobacteria (a type of bacteria), spirulina cannot be derived from other food sources - it must be directly harvested or cultivated as an organism.
Potential side effects & risks
Warnings
Individuals with autoimmune conditions should use with caution due to immune-stimulating effects. Those with phenylketonuria (PKU) should be aware of phenylalanine content. Source quality is critical - contaminated sources may contain harmful microcystins, heavy metals, or bacterial contaminants. Pregnant women should consult healthcare providers before use.
Side effects
Generally well-tolerated. Some individuals experience digestive discomfort, nausea, or headaches when beginning supplementation. May cause green discoloration of stools. Rare allergic reactions can occur in those sensitive to algae or seafood proteins.
Interactions
May enhance the effects of anticoagulant and antiplatelet medications due to vitamin K content. May affect immunosuppressant medications due to immune-enhancing properties. Could potentially interfere with certain medications metabolised by the liver.
